essay on the impact of overpopulation

Overpopulation Essay

500 words essay on overpopulation.

Overpopulation refers to an undesirable condition in which the number of existing human being exceeds the actual carrying capacity of the earth. It has many causes which range from a decline in the death rate to early marriages and more. The overpopulation essay will throw light on this issue.

Ill-Effects of Overpopulation

The ill-effects of overpopulation are quite severe. The first one is that natural resources deplete at a faster level. Our planet can produce only a limited amount of water and food . Thus, overpopulation causes environmental damage including deforestation, pollution, etc.

Similarly, there is the degradation of the environment which happens because of the overuse of resources like coal, oil, natural gases and more. As a result, the quality of air also gets affected in this manner.

In developing countries, overpopulation puts a strain on resources. Thus, it gives rise to conflicts and tension. It also causes more diseases that become harder to control. Next up, we have the issue of unemployment.

Moreover, it rises due to overpopulation. There is more number of people than job opportunities. As a result, unemployment gives rise to crimes like theft and more. We also have pandemics and epidemics which happen due to overpopulation.

It is because overcrowded and unhygienic living gives rise to infectious diseases . Another ill-effect is malnutrition and starvation. When there are scarce resources, these diseases will likely to be on the rise.

Most importantly, we have a shortage of water which makes it tougher for people to get access to clean water. Similarly, lower life expectancy also happens because of the boom in population, especially in less-developed nations.

We also witness faster climate change as nations continue to develop their industrial capacities. Thus, they emit industrial waste which gives rise to global temperatures . It will keep getting worse if things are not checked immediately.

Solutions of Overpopulation

There are many solutions which we may take up to prevent overpopulation. The best measure is family planning to keep the overpopulation check. In order to do that, one can ensure proper spacing between the births of the children.

Further, limiting the number of children as per income and resources must also be important. Similarly, it is essential to increase resources. The government must make the horrors of overpopulation reach the public through the use of media.

Moreover, better education can help implement social change which can curb overpopulation. Next up, knowledge of sex education must be made mandatory in schools so students learn young about everything they need to know.

Most importantly, it is essential to empower women so they can break out of poverty. This way, they can learn about reproductive health and make better decisions. Another solution can be government incentives.

Many governments of countries already have various policies which relate to tax exemptions for curbing overpopulation. For instance, some waive a certain part of income tax for married couples with one or two children.

Conclusion of Overpopulation Essay

All in all, overpopulation is no less than a curse that poses a permanent threat to the development of any country. It is essential to stop the flood of population. In order to do that, one must indulge in proper family planning and creating balance in society for a better world.

FAQ of Overpopulation Essay

Question 1: What is the main cause of overpopulation?

Answer 1: It is believed that the main cause of overpopulation is poverty. When there is a lack of education resource which coupled with high death rates, it results in impoverished areas witnessing large booms in population.

Question 2: How is overpopulation affecting the world?

Answer 2: Overpopulation is affecting the world as it is outpacing the ability of the planet earth to support it. It also has environmental and economic outcomes which range from the impacts of over-farming on global warming.

Overpopulation: Cause and Effect

A large group of people walking in a city

Conversations about overpopulation can quickly become controversial because they beg the question: Who exactly is the cause of the problem and what, if anything, should be done about it? Many population experts worry discussions around overpopulation will be abused by small-minded people to suggest some are the “right people” to be on the planet (like themselves), and some people are “the wrong people” (usually people in poverty, people of color, foreigners, and so on—you get the drift). But there are no “right” or “wrong” people on the planet, and discussing the problems of global overpopulation can never be an excuse, or in any way provide a platform, for having that type of conversation.

Each human being has a legitimate claim on a sufficient and fair amount of Earth’s resources. But with a population approaching 8 billion, even if everyone adopted a relatively low material standard of living like the one currently found in Papua New Guinea , it would still push Earth to its ecological breaking point. Unfortunately, the “average person” on Earth consumes at a rate over 50% above a sustainable level. Incredibly, the average person in the United States uses almost five times more than the sustainable yield of the planet.

When we use the term “overpopulation,” we specifically mean a situation in which the Earth cannot regenerate the resources used by the world’s population each year. Experts say this has been the case every year since 1970, with each successive year becoming more and more damaging. To help temper this wildly unsustainable situation, we need to understand what’s contributing to overpopulation and overconsumption and how these trends are affecting everything from climate change to sociopolitical unrest.

The causes of overpopulation.

Today the Earth is home to over 8 billion people. By 2100 the population is on track to hit 10.8 billion , according to the United Nations — and that’s assuming steady fertility declines in many countries. Interestingly, if extra progress is made in women’s reproductive self-determination, and fertility falls more than the United Nations assumes is likely, the population in 2100 might be a relatively smaller 7.3 billion.

For now, the world’s population is still increasing in huge annual increments (about 80 million per year), and our supply of vital non-renewable resources are being exhausted. Many factors contribute to these unsustainable trends , including falling mortality rates, underutilized contraception, and a lack of education for girls.

Falling Mortality Rate

The primary (and perhaps most obvious) cause of population growth is an imbalance between births and deaths. The infant mortality rate has decreased globally, with 4.1 million infant deaths in 2017 compared to 8.8 million in 1990, according to the World Health Organization (WHO). This is welcome public health news, of course.

At the same time, lifespans are increasing around the world. Those of us who are alive today will likely live much longer than most of our ancestors. Global average life expectancy has more than doubled since 1900 , thanks to advancements in medicine, technology, and general hygiene. Falling mortality rates are certainly nothing to complain about either, but widespread longevity does contribute to the mathematics of increasing population numbers.

Underutilized Contraception

The global fertility rate has fallen steadily over the years, down from an average of 5 children per woman in 1950 to 2.4 children per woman today, according to the UN Population Division . Along with that promising trend, contraceptive use has slowly but steadily increased globally, rising from 54% in 1990 to 57.4% in 2015. Yet, on the whole, contraceptive use is still underutilized. For example, according to the WHO, an estimated 214 million women in developing countries who want to avoid pregnancy are not using modern contraceptives.

These women aren’t using contraceptives for a variety of reasons, including social norms or religious beliefs that discourage birth control, misconceptions about adverse side effects, and a lack of agency for women to make decisions around sex and family planning. An estimated 44% of pregnancies were unintended worldwide between 2010-2014. Getting more women the access and agency to utilize family planning methods could go a long way in flattening the population curve.

Lack of Female Education

Although female access to education has increased over the years, the gender gap remains. Roughly 130 million girls worldwide are out of school currently, and an estimated 15 million girls of primary school age will never learn to read and write, compared with 10 million boys.

Increasing and encouraging education among women and girls can have a number of positive ripple effects, including delayed childbearing , healthier children, and an increase in workforce participation. Plenty of evidence suggests a negative correlation between female education and fertility rates.

If increased female education can delay or decrease fertility and provide girls with opportunities beyond an early marriage, it could also help to mitigate current population trends.

The Effects of Overpopulation

It is only logical that an increase in the world’s population will cause additional strains on resources. More people means an increased demand for food, water, housing, energy, healthcare, transportation, and more. And all that consumption contributes to ecological degradation, increased conflicts, and a higher risk of large-scale disasters like pandemics.

Ecological Degradation

An increase in population will inevitably create pressures leading to more deforestation, decreased biodiversity, and spikes in pollution and emissions, which will exacerbate climate change . Ultimately, unless we take action to help minimize further population growth heading into the remainder of this century, many scientists believe the additional stress on the planet will lead to ecological disruption and collapse so severe it threatens the viability of life on Earth as we know it.

Each spike in the global population has a measurable impact on the planet’s health. According to estimates in a study by Wynes and Nicholas (2017) , a family having one fewer child could reduce emissions by 58.6 tonnes CO2-equivalent per year in developed countries.

Increased Conflicts

The scarcity brought about by environmental disruption and overpopulation has the potential to trigger an increase in violence and political unrest. We’re already seeing wars fought over water, land, and energy resources in the Middle East and other regions, and the turmoil is likely to increase as the global population grows even larger.

Higher Risk of Disasters and Pandemics

Many of the recent novel pathogens that have devastated humans around the world, including COVID-19, Zika virus, Ebola, and West Nile virus, originated in animals or insects before passing to humans. Part of the reason the world is entering “ a period of increased outbreak activity ” is because humans are destroying wildlife habitats and coming into contact with wild animals on a more regular basis. Now that we’re in the midst of a pandemic, it has become clear how difficult it is to social distance in a world occupied by nearly 8 billion people.

Discover the real causes and effects of overpopulation

What can be done about overpopulation.

When addressing overpopulation, it’s crucial to take an approach of providing empowerment while mobilizing against anybody advocating for the use of coercion or violence to solve our problems. The combined efforts of spreading knowledge about family planning, increasing agency among women , and debunking widely held myths about contraception will measurably change the trajectory of the world’s population.

As we carry out our work at Population Media Center (PMC), we see first-hand that spreading awareness about family planning methods and the ecological and economic benefits of having smaller families can change reproductive behavior. For example, listeners of our Burundian radio show Agashi (“Hey! Look Again!”) were 1.7 times more likely than non-listeners to confirm that they were willing to negotiate condom use with a sexual partner and 1.8 times more likely than non-listeners to say that they generally approve of family planning for limiting the number of children.

CELEBRATING EARTH DAY WITH CONVERSATIONS ON OVERPOPULATION

In the spirit of Earth Day, it’s crucial to approach discussions about overpopulation with sensitivity and inclusivity. Overpopulation conversations should focus on the collective responsibility to steward Earth’s resources sustainably, rather than assigning blame or dividing communities. By fostering understanding and promoting access to education and reproductive health services, we can work towards a more equitable and sustainable future for all.

At PMC we harness the power of storytelling to empower listeners to live healthier and more prosperous lives, which in turn contributes to stabilizing the global population so that people can live sustainably with the world’s renewable resources.

Can We Talk About Overpopulation?

As numbers soar, scholars revisit a thorny debate.

Twenty years ago, farmers looked out at the tropical woodlands and savannahs of Uganda and saw endless virgin territory. A young man, upon starting a family, would clear a patch of wilderness near where he was raised and plant his own fields of sorghum, millet, groundnut, plantains, or cassava.

Now, after decades of unprecedented population growth, the land is running out. In southern Uganda, as in many parts of sub-Saharan Africa, farm communities are bumping up against one another and against dry lands, mountains, and rain forests. Pockets of arable land can still be found, but only in malaria-ridden hinterlands where nobody wants to live. Many farmers, rather than relocating long distances, are clearing rain forests near their homes, despite the fact that a tropical forest’s acidic soil is poorly suited to growing grains, fruits, and vegetables. Other farmers are subdividing their parents’ land, reducing the typical-sized farm plot in some parts of Africa to half an acre.

“That’s too small to feed a family,” says economist Jeffrey D. Sachs, who directs Columbia’s Earth Institute.

Africans will never be able to grow enough food for themselves, Sachs argues in his latest book, Common Wealth: Economics for a Crowded Planet , unless they start having fewer babies. Subsistence farmers in sub-Saharan Africa today raise an average of six children, which is causing the populations of some nations to double every 20 years. Few of these farmers are able to feed their children properly, let alone afford their education. Children thus grow up desperately poor and have huge families of their own. Shrinking farm plots add yet another burden: Food production on a per-capita basis is declining and malnutrition is worsening, which means that children are likely to grow up even less healthy and less productive.

“The poorest places in the world right now are stuck in a demographic trap,” says Sachs. “A family of subsistence farmers with six or seven kids doesn’t stand a chance.”

The only way to break this cycle of overpopulation and misery, Sachs writes in Common Wealth , is for wealthy nations to provide birth control to the world’s poor. Sachs recommends that rich countries quadruple foreign assistance for reproductive health programs to roughly $25 billion annually. That’s enough money, he estimates, to provide birth control, as well as maternal health care and STD treatment, to some 200 million women who lack it; most of them live in rural Africa.

The prospect of giving poor people contraceptives so they can lift themselves out of poverty might not seem particularly controversial, aside from the opposition that might be expected from some religious conservatives. Yet Sachs is the first mainstream economist in decades to formally propose this idea. Since the 1980s, family planning programs have been promoted strictly as a human right, not as a way to kick-start economic development. That’s because Western family planners in the 1960s and 1970s, in their zeal to slow population growth and to spur development in Asia, supported forced sterilizations, slum demolitions, and other abuses. Women’s rights advocates subsequently wrested control of international family-planning programs and made sure they never again aimed explicitly to lower birthrates.

The days of promoting birth control purely as a way to empower women, however, may be ending. There is a growing sense among scholars that the topic of overpopulation — which has faded from public consciousness as the world’s population growth rate has declined from its mid-1960s peak of 2 percent annually down to about 1.2 percent — is going to reemerge as a hot topic. Recently, the Sierra Club, the Worldwatch Institute, and other environmental groups have offered recommendations similar to those in Common Wealth , in which Sachs urges that we halt world population at 8 billion by 2050, rather than allowing it to grow to 9 billion from today’s 6.7 billion, as the UN projects.

Still, many population experts wonder: Is the marriage bed really the place to address economic and environmental problems? Is it even possible to manage people as numbers while respecting them as human beings?

Don’t blame the victim

Joel E. Cohen, a Columbia demographer, is an expert on population growth and environmental sustainability. He cringes at the term overpopulation .

“I have no idea what that word means, and you’ll never hear me use it,” he says. “It suggests that the size of a population can become so big that it starts causing problems in itself. That’s not the way it works. I’d put the situation this way: Rapid population growth makes it trickier for a poor country to deal with every problem that it faces, from distributing food and water during a drought to providing education and health care in rural areas. But it doesn’t cause these problems.”

There’s wide agreement among economists and demographers today that rapid population growth is troublesome. A report published in April by the UN Population Division concludes that high birthrates are hampering economic development across sub-Saharan Africa, mainly by limiting per-capita investments in education and health care. (Columbia economist Xavier Sala-i-Martin has shown that high birthrates typically stunt economic development.) The UN report also states that population pressure is worsening food and water shortages in the region. Environmental concerns also are real: rain forests in sub-Saharan Africa and in South America are being destroyed primarily by subsistence farming, according to NASA data, and deforestation is reducing local rainfall and exacerbating global climate change.

Cohen’s concern is that people often imagine a direct causal link between population growth and problems like hunger, poverty, and environmental degradation. It’s easy to think this way when visceral images of teeming third-world slums and starving masses invite human-scale explanations: Why do these people have so many babies? Cohen says we then may ignore political factors that contribute to these problems. For instance, agriculture subsidies in rich nations contribute to hunger by driving down farm incomes in the developing world; and African governments are famous for mismanaging food and water supplies. “During the Ethiopian famines of the 1980s, cash croppers in that country were allowed to export alfalfa to Japan as cattle feed,” he says. “Is that a population problem? I don’t think so.”

Cohen agrees with Sachs that international family-planning programs are underfunded. But he says that family planning should continue to be promoted — both to Western donors and to government officials in developing countries — strictly as a human right. To advance birth control as a means to slow population growth, Cohen says, implies that poor people need to solve their societies’ problems through private choices of childbearing. Might this cause the West to back away from other aid obligations, or inspire poor countries to implement coercive methods of population control?

Cohen hesitates. “It’s not as if a developing country’s problems are going to vanish if it manages to lower birthrates,” he says. “I would say that until the West has done its utmost to give poor people access to education, health care, job training, and family planning for the purpose of giving them more control over their lives, it’s premature to talk about trying to convince them to have fewer babies.”

Dirt to dust

Sachs insists that we speak clearly about population pressures. The problem of dwindling farmland in sub-Saharan Africa, he says, is insurmountable without a major effort to slow population growth.

As arable land in Africa has vanished, Sachs explains in Common Wealth , farmers have abandoned land-management techniques they used previously to sustain the long-term fertility of their fields, such as allowing one of the fields to lie fallow each season. Three-quarters of all arable land in sub-Saharan Africa today is severely depleted of nutrients because it has been overused, according to a recent study by the International Center for Soil Fertility and Agricultural Development.

A doubling of the region’s population since the early 1980s helps explain why almost all of sub-Saharan African countries now depend on foreign food aid. Until a few years ago, most were food exporters . “There’s a tyranny of the present at work,” Sachs writes, “and the poor, in their desperation to survive, are often contributing to massive local environmental degradation.”

Population control isn’t the only way to address food shortages, of course. Sachs points out that farmers in sub-Saharan Africa can’t afford chemical fertilizers, high-yield seed varieties, or modern irrigation. He and colleagues at the Earth Institute, as part of the United Nations Millennium Villages project, which Sachs initiated, are helping the governments of a dozen nations in Africa introduce modern farm technologies. They’ve had some remarkable success: The tiny, famine-prone nation of Malawi has tripled its grain yields in the past two years by subsidizing chemical fertilizer for all farmers.

“The problem is that these kinds of agricultural improvements never will produce gains to keep pace with a doubling of population every generation,” Sachs says.

Other types of foreign aid, such as for education or health care, also will bring diminishing returns if population growth rates don’t decline, says Sachs, who is academia’s most influential proponent of aid to Africa. He says that countries in sub-Saharan Africa now must spend huge portions of their budgets providing basic services, which leaves little money for the type of agricultural investment that Malawi is making in its fertilizer program. Economists thus say that countries experiencing explosive population growth must expend their budgets on “service widening,” to deliver basic services to more and more people, rather than on “service deepening,” to improve average services per person.

“If people continue having huge numbers of kids, and if farm sizes continue to shrink,” Sachs says, “I can’t imagine how the next generation is going to make it.”

Sordid history

Back in the 1960s, the populations of many poor countries in Asia, Latin America, and North Africa were growing as rapidly as the populations in sub-Saharan African countries are today. International health programs had gone into former colonies in these areas following World War II with antibiotic drugs, vaccines, and pesticides, which lowered mortality rates dramatically. Farmers in poor countries had always had lots of babies: They needed to, in order to ensure that at least one son grew up to work their fields and to take care of them in their old age. The problem was that while more of their children were surviving, rural people retained a cultural proclivity for huge families. Furthermore, they had little or no access to modern birth control, so they ended up with even more kids than they would have otherwise chosen.

Population growth soon was outpacing food production, especially in Asia, causing Western officials to fear that widespread famine would destabilize the continent, Columbia history professor Matthew Connelly explains in his latest book, Fatal Misconception: The Struggle to Control World Population . President Lyndon B. Johnson and his advisers viewed the situation through a lens of Cold War–inspired paranoia: Johnson, speaking to U.S. troops stationed in South Korea in 1966, warned that hordes of starving Asians might one day “sweep over the United States and take what we have.” His fear didn’t seem so irrational: 19 Nobel laureate scientists in 1960 had issued a public letter decrying how overpopulation could push the world into “a Dark Age of human misery, famine, and under-education, which could generate growing panic, exploding into wars.”

So in the late 1960s, the U.S. government began pouring tens of millions of dollars annually into international family-planning programs. The programs were administered primarily by Planned Parenthood, under the auspices of the newly formed United Nations Population Fund (UNFPA), which was financed largely by U.S. dollars and which claimed that its programs provided contraceptives, sterilization procedures, and abortions on a voluntary basis. In reality, American and British economists and demographers had designed these programs to slow population growth by nearly any means necessary, according to Connelly.

South Asian countries with caste systems were willing to push family planning most aggressively, Connelly writes, because many ruling-class Hindus feared social unrest among the hungry lower castes. So Indian officials, under the guidance of Western family planners, agreed to pay famished people small sums of money to be sterilized; they also agreed to fire doctors who didn’t meet sterilization quotas. India, Pakistan, Bangladesh, and Sri Lanka implanted in women a type of intrauterine contraceptive device that was proven to cause infections and the rupturing of the uterine wall. Couples in all of these countries lost medical, housing, and education benefits for having more than a designated number of children. When local health officials balked at implementing aggressive programs, the U.S. Agency for International Development and the UN threatened to shut off Western food aid.

The endgame for this chapter of family planning started to unfold in 1975, when Indira Gandhi’s government bulldozed entire blocks of Delhi slums where large numbers of residents refused to be sterilized. Around the same time, police rounded up at gunpoint all of the men in the Indian village of Uttawar and forced them to get vasectomies. These atrocities drew international outrage and led to Gandhi’s being voted out of power the following year. They also prompted a backlash from feminists and women’s rights advocates who were assuming leadership roles within the NGO community in the 1970s.

International family-planning programs, which by this time had spread throughout Latin America and North Africa, gradually abandoned coercive methods over the next few years. The population control movement would have one last gasp, though, when UNFPA and Planned Parenthood helped China launch its draconian one-child policy in 1979.

Women’s choice

By the late 1980s, the UNFPA and Planned Parenthood had cleaned up their programs so that medical workers on the ground no longer were expected to lower birthrates. Clinicians now concentrated on helping women make informed choices about their sex lives and childbearing. If family planning executives discussed the prospect of slowing population growth in public, Connelly says, it was only as an ancillary benefit of giving women more control over their bodies.

“The term population control has since had a negative connotation, as well it should,” Connelly tells Columbia .

The economic benefits of slowing population growth, though, were apparent: as birthrates plummeted in most of the developing world, prosperity and modernization typically arrived. The governments of many countries in Asia and Latin America, now that they had proportionately fewer poor people to care for, could afford to invest in industry and modern agricultural methods, which boosted grain production 300 percent in some nations between the 1960s and the 1980s. (Connelly, in Fatal Misconception , makes the controversial argument that family planning programs have received too much credit for declining birthrates, and hence for development; see sidebar to the left.)

The good news for women’s rights advocates was that voluntary family-planning programs seemed to have lowered birthrates just as much as had coercive programs. For instance, a UN-sponsored program that had offered birth control pills to all poor women in Thailand in the 1960s, on the advice of a young field-worker named Allan Rosenfield, who later became dean of Columbia’s public health school, helped to halve the number of children born per woman in that country, from six to three, in less than 20 years. Across the developing world, birthrates declined where family planners provided a range of safe contraceptives and taught people the benefits of limiting their family size — not only where they bribed people to be sterilized or threatened tax penalties.

Yet, just as family planning programs were beginning to define a new humanitarian mission, funding stagnated. The trouble started during Ronald Reagan’s first term as president, Connelly writes, when the emerging pro-life movement in the U.S. launched a major lobbying effort against international family-planning programs. Abortion opponents called attention to the fact that Planned Parenthood and UNFPA were providing technical assistance to China for its country’s one-child policy, which in the mid-1980s was in its most coercive phase, allegedly requiring some women to have abortions and to be implanted with intrauterine devices. “It was not much,” writes Connelly, “but it was enough of a perch to permit pro-lifers to pile calumny upon calumny on China’s program and all who could be associated with it.” Since then, every Republican president has refused to contribute to UNFPA, which is the primary source of funding for international family-planning services. Partly as a result, financial support for international family planning has remained flat, which means that the funding hasn’t kept pace with increasing demand as populations in poor countries continue to climb.

Sub-Saharan Africa is home to most women who lack access to birth control today in part because family planning programs arrived to the region late, in the 1980s, when the money had already begun to dry up, say family planning executives. Family planning came to Africa late, they say, because international health programs, with their ensuing population boom, had arrived late, too.

A lack of money isn’t the only thing that has kept family planning from many Africans, though: “There is mistrust in some nations about family planning programs because of their checkered past,” Connelly says. “In African countries where there are ethnic tensions, for instance, it can be politically difficult for leaders to implement family planning programs because many people fear that they’ll be used to reduce the populations of some groups, and not others.”

Counting backward

Today, UN-backed family-planning programs operate in nearly all developing countries. If the UNFPA were better funded, say its proponents, birth control would be more available in rural Africa as well as in many Muslim and Catholic countries, where Western family planners must work hard to educate local leaders about the benefits of reproductive health services.

How to raise the money? Advocates for family planning are doing a lot of soul-searching these days. Many leaders in the NGO community believe that family planning organizations would be better financed if they once again promoted their work as a way to slow population growth, says Suzanne Petroni, a researcher who monitors funding for reproductive health programs at the Summit Foundation, a Washington, D.C.–based nonprofit that promotes environmental sustainability.

“The sense among many family planners is that they’re getting less money than they used to from Western donors, in part because their programs are no longer connected to a practical purpose,” says Petroni. “They believe that the human rights pitch hasn’t worked.”

Particularly tempting to some family planners, Petroni says, is the prospect of exploiting public concerns about global warming. The sales pitch would go something like this: if we limit the number of people on earth, we limit the number of carbon footprints. (Sachs validates this logic in Common Wealth , warning that decades from now, when the crowded nations of sub-Saharan Africa modernize — and Sachs is optimistic that they will modernize eventually — energy consumption on the continent will skyrocket.)

Many women’s rights advocates fear that if family planning programs are positioned once again as a means to combat overpopulation, the door will open for more human rights abuses, Petroni says. This debate within the aid community is contentious because there remains distrust between feminists and some older environmentalists who backed the original population-control movement.

Matthew Connelly sides with the women’s rights advocates. He was convinced in writing Fatal Misconception , he says, that family planning programs that aim to lower birthrates are bound to commit abuses. He found, for instance, that crimes occurred in the 1960s and 1970s even when Western family planners tried to operate their programs ethically: medical workers in several South Asian countries strong-armed patients into accepting sterilizations because they thought that lowering birthrates was good for their own careers, and family planning programs inevitably devoted more resources to sterilization procedures and to abortions than to follow-up care.

Connelly worries that Western nations, if their aid programs once again were promoted as a means to slow population growth, would be tempted to withhold other forms of development aid from countries if they don’t lower birthrates to specified levels.

Lynn Freedman, a Columbia public health professor and an attorney who is an expert on population issues, concurs. “The idea that foreign aid could be linked to a country’s success at lowering birthrates is not wildly unlikely,” she says. “Aid agencies today are in the habit of designing all sorts of performance targets in order to account for the efficiency of their programs, and these targets can easily be misused in a way that violates people’s rights. The ’60s weren’t that long ago.”

Sachs doesn’t see that happening. “The worst I could imagine is that an agency might attempt to link a country’s family- planning money to birthrate reductions,” he says, “but I don’t think that other kinds of foreign aid would be linked in this way.” He also dismisses as unrealistic the possibility that international family-planning programs could once again employ coercive methods. Family planning programs must, and will, remain voluntary, he believes.

The greater moral danger today, Sachs argues, is that large numbers of women will continue to want for birth control, and populations will continue to grow rapidly in sub-Saharan Africa and in places like Haiti, Bolivia, Venezuela, Yemen, Afghanistan, Iraq, and Myanmar, in part because Western scholars and aid workers insist on tiptoeing around the subject of overpopulation for fear of being seen as insensitive to the abuses of the past. In Common Wealth , Sachs even advances the term population control, which has long been considered impolitic among scholars, because he says he wants to break the taboo.

“For years people have been telling me, ‘Don’t talk about population, talk instead about access to reproductive health services,’” Sachs says. “And I’ve said, ‘No, I want to talk about population, because it’s a serious problem.’ I think it’s time we take this subject out of the whispers.”

Birth control, under audit

Columbia professor Matthew Connelly’s Fatal Misconception, a history of the population-control movement of the 1960s and 1970s, is shocking for its parade of morally compromised scholars and diplomats who spread birth control around the world. There’s Planned Parenthood head and ecologist William Vogt, who thought that starving people in the developing world should be left to die and therefore opposed food aid; there’s Robert McNamara, who, as head of the World Bank, resisted funding healthcare programs in poor countries because they saved lives and contributed to overpopulation; there are the Planned Parenthood doctors who at a 1963 UN conference decided that a female contraceptive’s tendency to pierce the uterus, causing sterilization, was to be considered a side benefit.

Fatal Misconception was among the most controversial scholarly monographs of 2008, not just because Connelly calls out early family planners as xenophobic and racist, however. His most startling critique is that these programs didn’t even lower birthrates as designed: he says that between 1950 and 2000, the dozen or so developing nations that employed the most aggressive family- planning tactics reduced birthrates little more than did other countries. Relying on UN data, Connelly notes that China, for instance, reduced the number of children per woman from 6.2 to 1.7 during that 50-year period. In Brazil, where little effort was made to encourage family planning, the numbers fell from 6.2 to 2.3 children during the same period. Connelly lists half a dozen such examples to make his point. He then argues that girls’ education, women’s employment, and other social factors affected birthrates more so than did family planning programs.

“In many poor countries where birthrates declined dramatically,” Connelly tells Columbia, “the declines actually started before family planning programs even showed up.”

How could people have managed to have fewer babies without contraception? The same way they did in early-19th-century Europe, where birthrates plummeted a full century before modern birth control became available, Connelly says: They used traditional forms of birth control like the rhythm method.

Connelly charges that UN and Planned Parenthood officials who administered most family-planning programs in the 1960s and 1970s knew that data on the ground weren’t validating their efforts. They soldiered on, he says, because of institutional inertia. “These programs gave jobs to millions of people, and administrators weren’t interested in scrutinizing the numbers,” he says. “They were interested in making payroll.”

Many contemporary family planners are apoplectic over Connelly’s assertion that birth control programs don’t lower birthrates. Steven Sinding, a professor at Columbia’s Mailman School of Public Health and past director-general of Planned Parenthood International, has blasted Connelly over his book’s conclusions. Sinding claims that about 50 percent of birthrate declines in poor countries are attributable to family planning programs.

Columbia called T. Paul Schultz, a Yale economics professor who has spent his career studying birthrate dynamics. This subject invites confusion, he says, because no long-term controlled studies have ever been conducted. That’s partly because there are a multitude of factors that influence birthrates, so aid agencies whose programs target any one of these areas are reluctant to fund expensive, long-term studies to showcase the relatively small impact that their work likely has on fertility. The dearth of data, Schultz says, allows both advocates and opponents of family planning to cherry-pick statistics.

But the most sophisticated data available, collected over two decades in Bangladesh, Schultz says, suggest that the availability of free contraception accounted for about 20 percent of the region’s birthrate decline. That’s a strong relationship, considering how many variables were tested, he says. “The intuition of development experts has always been that family planning must slow population growth,” Schultz says, “and I’ve never seen any good data that suggest otherwise.”

A Brief on Overpopulation – Why it Matters and What You Can Do About It

As humanity has surpassed the 8 billion people milestone, it is more important now than ever to talk about population. What will we do if we continue to grow at exponential rates? What are ethical, viable strategies to decrease population?

“First off, let me get this straight, discussing addressing overpopulation does not mean discussing killing people. The goal is actually to prevent it.” – Dr. Jane O’Sullivan

Current world population in January 2023: 8 billion

The current rate of population growth is around 80 million people per year. There are over 8 billion people on the planet, the last billion added in less than the last 12 years.

The Earth’s first billion people milestone took from the beginning of human history until the 1800s to be achieved. Then, due to the industrial revolution, humanity reached the second billion mark by 1930 (taking only 130 years), reached the third billion in 1960 (only took 30 years), then reached the fourth billion by 1974 (only took 14 years), and the fifth billion by 1987 (only took 13 years). We hit 6 billion in 1999 (which took 12 years) and hit 7 billion in 2011 (which took about 12 years). At the current growth rate, the world population will reach 9 billion by 2037 and 10 billion by 2057.

The growth rate is declining, but not at a fast enough rate to combat the exponential compound growth. The growth rate was 2% in the 1970s. Now it is 1.05%. Any growth rate above 1% means we are still adding more people to the planet every year.

What is overpopulation?

Overpopulation is a human population in numbers high enough to cause environmental deterioration, impaired quality of life, or population crash.

Why is overpopulation an issue?

Overrun natural resources can only lead to death by starvation, conflict, and disease, and the only viable alternative is voluntary restraint on human births.

What is carrying capacity?

Carrying capacity is defined as the maximum population of a species that an area will support without undergoing deterioration.

Paul R. Ehrlich and other scientists estimate the world’s optimum population for carrying capacity (at a comfortable standard of living – editor’s note) to be less than two billion people – 6 billion fewer than on the planet today. “But the longer humanity pursues business as usual, the smaller the sustainable society is likely to prove to be. We’re continuously harvesting the low-hanging fruit, for example by driving fisheries stocks to extinction” – Paul Ehrlich says.

How do we revert population overshoot to a sustainable population level?

Geologist Art Berman explains population overshoot this way: “Overshoot means that humans are using natural resources and polluting at rates beyond the planet’s capacity to recover. The main cause of overshoot is the extraordinary growth of the human population made possible by fossil energy. Concerns about overshoot and population raised more than 40 years ago were dismissed. Climate change has captured public awareness more recently although many doubt that it is an emergency. Overshoot is more difficult to dispute; it destroys rainforests, leads to the extinction of other species, the pollution of land, rivers, and seas, the acidification of the oceans, and the loss of fisheries and coral reefs. People understandably want to know the solutions. Overshoot is the problem we must address. Any plan that includes continued growth is doomed to fail.”

What can we do? Jane O’Sullivan outlines the two options for addressing population overshoot – i ncrease the Earth’s carrying capacity or decrease population.

Increasing Earth’s carrying capacity

We are already doing this by (a) using fewer natural resources per person, or (b) increasing productivity by finding more ways to use resources. This only defers the problem and creates collateral damage.

Decreasing population numbers

If we talk about this now, the hope is to increase our options for solutions. One of the biggest challenges to facing overpopulation head-on and discussing a decreasing population are the stigmas and myths associated with reducing human population numbers. An elaborate set of myths has emerged in opposition to reducing population levels. These myths may prevent even environmentalists from viewing overpopulation as an issue. Jane O’Sullivan elucidates on the following six myths that make inaction a virtue.

Myth 1 – The human population is stabilizing, and birth rates are decreasing

Truth – Birth rates started declining in the 1970s-90s due to family planning, but not low enough. The number of mothers is still increasing faster than family planning is decreasing the birth rate . We are still having more births per year than ever before. The total fertility rate has decreased, but as fertility decline has slowed to a trickle, the number of total births has continued to increase.

Myth 2 – China is the only one with the problem and they used cruel methods (one-child policy)

Truth – Family planning programs have helped many countries successfully reduce births through voluntary means, including China, before the one-child policy.

Myth 3 – Poverty causes population growth, therefore development is the best contraceptive

I.e., family planning is unnecessary and inefficient as long as there is development.

Truth – If this was true, we would see the population decline as development increases. However, it is the decrease in fertility rates that drove economic development, not the other way around. This myth is therefore “correlation implying causation” in the wrong direction. The poorest countries could lower their population by family planning just as quickly as rich countries if they choose to prioritize it.

Countries of families with four or more children, on average, have the lowest level of development; in families with 3 children or fewer the level goes up by some degree, and with two or fewer children development soars. The current focus should be on expanding provisions for teachers, doctors, equality, etc. instead of just giving people what they need.

Myth 4 – Educating girls is the key to ending population growth

Truth – Another indirect approach that excludes a discussion on the benefit of small families and ending population growth. Educating girls helps but not much unless it is also flanked by family planning efforts. Family planning has a stronger effect on women regulating their fertility, decreasing the fertility gap between the educated and uneducated, and with family planning, girls are more likely to stay in school.

Myth 5 – Population growth is good for the economy

Truth – This makes people poorer as shown under Myth #3.

Myth 6 – Population growth in poor nations does not matter because of their “tiny carbon footprint”

Truth – Population growth is a greater threat than climate change. The best way for anyone to decrease their carbon footprint is to have one less kid.

Therefore, family planning is the most economical way to a sustainable future.

What action can each of us take?

1. Discuss smaller family sizes with your partner, family, and friends – how do we aim for birth rates lower than two children per couple?

2. Share information about the environmental impacts of population growth with friends and family. Advocate for action to reduce and reverse population growth.

3. Reassess concerns about aging – how can we shift away from worshipping eternal youth, to accepting and valuing the entire life cycle?

4. Celebrate population decline – what are possible depopulation dividends?

5. Support organizations and efforts that support family planning and women’s education.

Damien Carrington, an environmental editor at The Guardian, interviewed Prof. Paul Ehrlich about the solutions:

“The solutions are tough,” Ehrlich says. “To start, make modern contraception and backup abortion available to all and give women full equal rights, pay, and opportunities with men. Focus on overconsumption and equity issues. Specifically women’s rights and the explicit countering of racism.”

Ehrlich also says that an unprecedented redistribution of wealth is needed to end the over-consumption of resources, but “the rich who now run the global system – that hold the annual ‘world destroyer’ meetings in Davos – are unlikely to let it happen…Too many rich people in the world is a major threat to the human future, and cultural and genetic diversity are great human resources… It is a near certainty in the next few decades, and the risk is increasing continually as long as the perpetual growth of the human enterprise remains the goal of economic and political systems. As I’ve said many times, ‘perpetual growth is the creed of the cancer cell’.”

If cultural and genetic diversity are great human resources, how can the rich and the poor come together across the world to solve this issue?

Anne and Paul Ehrlich expand on their “vision for a cure” :

“Rich white people love to hold meetings to discuss the ‘population problem’ which always ends up focusing on the very real demographic difficulties of those with darker skin tones, especially people who live in Africa and Latin America. But isn’t it really time for the poor people of the world, especially those not in need of tanning beds, to extend a helping hand to the major villains of the destruction of humanity’s life-support systems? Could they not hold an educational conference in Washington, D.C. to explain why civilization is going down the drain, to the per-capita most environmentally destructive giant nation on the planet? Leaders from the “South” could both organize the event and supply experts to educate the wealthy and middle class on their ethical responsibilities and ways to meet them. We envision learning sessions on topics such as:

Avoiding the second child.
The population problem beyond numbers: inequality and waste of talent.
Are borders ethical?
Population shrinkage for politicians.
GDP shrinkage for economists.
Do Trump and his colleagues prove that the lighter your skin, the lighter your brain?
Citizens United: It’s time for euthanasia for corporations.
Redistribution and survival.
Disbanding “Murder Incorporated”: gun manufacturers and big pharma.
How to end plastic production.
The historical contributions of the global South to the food enjoyed by the North.
How biodiversity loss is accompanied by the loss of human cultural diversity.
We know our populations are growing too fast; how to help us help ourselves?

You can doubtless think of others. The possibilities are endless”.

Public Health and Overpopulation: The United Nations Takes Action

With the world’s population rising faster than ever before, will our population growth outpace our resource reserves? How can the dangerous effects of overpopulation be managed without diminishing the major improvements in our quality of life that come about thanks to population growth?

The UN projects that over half of the Earth’s population growth in the next three decades will occur in the continent of Africa. This is due to the fact that, from 2010 to 2015, Africa’s population grew at a rate of 2.55 percent annually, with the continent still maintaining the highest pace of population growth among other continents. The UN predicts that, behind Africa, Asia will be the second greatest donor to future international population growth, with an expected addition of approximately one billion people by 2050. In contrast, within every European nation, fertility rates are currently below the population replacement level, which is approximately two children per woman. In most of Europe, fertility rates have remained beneath replacement level for decades. The global population grew fourfold in the past 100 years, so what impact could increased population growth have in the future? Will there be mass-migration? Overcrowding in already densely populated or resource-rich areas? Poor living conditions and sanitation similar to Industrial Revolution era slums?

The global population is currently rising at a steady rate. The number of humans existing on Earth has never been as high as it is now. In 1800, Earth had approximately 1 billion inhabitants, which rose to 2.3 billion in 1940, then 3.7 billion in 1970, and approximately 7.5 billion today. In the last five decades, Earth has experienced an extreme population boom. This phenomenon is known as overpopulation, where the condition in which the amount of humans currently existing on Earth outstrips future resource availability and earth’s carrying capacity. Throughout human history, birth and death rates have always counterbalanced each other, which ensured that Earth had a maintainable population growth level. However, in the 1960s, the global population increased at an unparalleled rate. This brought about a variety of apocalyptic predictions, most prominently, a revival of the Malthusian trap panic.

Paul R. Ehrlich’s 1968 novel, The Population Bomb , eerily echoes Thomas R. Malthus’s landmark 1798 Essay on the Principle of Population . Ehrlich’s novel proposes theories regarding potential outcomes for when agricultural growth does not keep pace with population growth. Ultimately his theories say that the world’s food supply will inevitably become inadequate for feeding the general population, whose numbers would continue to swell until famine, disease epidemics, war, or other calamities took root. These Malthusian predictions about out-of-control population growth have resulted in a variety of detrimental global impacts, particularly the emergence of extreme reproductive control measures, which have taken center stage on an international scale. Today, despite the fact that population scientists mostly agree that Malthus’s forecasts were overblown, the lingering prevalence of these fears have contributed to millions of forced sterilizations in Mexico, Bolivia, Peru, Indonesia, Bangladesh and India, as well as China’s two-child policy . Overall, this has left many wondering whether extreme population growth projections are legitimate or merely groundless panic perpetuated by alarmists.

The Demographic Transition

In reality, rising birth rates and population booms are components of a four-step process called the demographic transition, which the Earth is currently undergoing. Most developed nations have already made this transition, but other countries are currently experiencing this change. In the 1700s, the entire world was undergoing the first stage of the demographic transition. During this time, the continent of Europe was in even poorer condition than the modern-day definition of a developing region, and was afflicted with inferior public health, sustenance, and medical facilities. Birth rates were higher; however, death rates were also higher. For this reason, population growth remained largely stagnant.

Statistically, in the 1700s, women birthed four to six children. However, on average, only two survived to adulthood. When the Industrial Revolution began in Great Britain in the mid-18th century, the Earth experienced the most significant shift in human lifestyles since the Agricultural Revolution. The Industrial Revolution altered every aspect of society, and fostered a greater sense of global interconnectedness. For example, many peasants became factory workers, manufactured products became widely available due to mass production, and countless scientific advancements improved existing methods of transportation, communication, and medicine.

Gradually, this economic development created a middle class and, after the work of union activists, ultimately raised the standard of living and health care for the impoverished labor demographic. Thus began the second transition stage. The increased availability of better foodstuffs, sanitation, and medicine directly contributed to lower death rates, causing a population explosion that doubled Great Britain’s population from 1750 to 1850. In the past, families tended to have more children because not all were expected to survive, but when child mortality rates decreased, the third transition stage was launched. This stage involves reduced conception rates and slowing population growth. Ultimately, a balance was established, with fewer deaths and births, creating a stable population growth rate and signifying the attainment of the fourth and final stage of the demographic transition.

Even as birth rates have decreased dramatically, Earth’s population is still rising at an alarming rate because the humans conceived during the population boom of the 1970s and 1980s are currently having more children; however, the current average number of children per family remains two and a half, while it was five during the late 1970s. As this generation ages and its fertility diminishes, the rate of population growth will likely continue to decrease in every nation. Most of the world’s countries have reached the fourth stage of the demographic transition. In approximately 80 years, developed countries will experience a reduction in fertility from over six children to fewer than three children. Malaysia and South Africa reached this point in 34 years, Bangladesh in 20 years, and Iran in 10 years. If developing countries are afforded more support, they will reach this point much faster.

Overall, most scientists postulate that human population growth will eventually come to an end, and the UN predicts that Earth’s population will not exceed twelve billion. Some of the major causes of population growth are reduced infant mortality rates, increased lifespans, higher fertility rates, advances in science and technology, and improved access to proper medical care. With the UN’s continued assistance, concurrent with overpopulation, the development level of the global community will increase, and the number of people living in poverty will decrease. Nonetheless, an ever-expanding human population is an immense social and economic challenge that necessitates the alignment of different national interests, especially with regards to reproductive rights, resource availability, and environmental concerns.

The United Nations Takes Action

In 1969, the United Nations Population Fund (UNFPA) was established in order to lead the UN in implementing population programs fundamentally based on the notion of family planning, or the “human right of individuals and couples to freely determine the size of their families” without governmental interference or legislation. In 1994, at the International Conference on Population and Development in Cairo, Egypt, the designated objectives of the UNFPA were determined in greater depth. It was decided that the UNFPA would specifically focus on the gender and human rights elements of population issues; consequently, the UN Population Fund was granted the lead role in aiding nations in fulfilling the Conference’s Programme of Action.

The three most significant sections of the UN Population Fund mandate are “Reproductive Health,” “Gender Equality,” and “Population and Development.” The United Nations Population Division (UNPD) works to confront the interconnected global issues posed by population growth, which is primarily fueled by rising fertility rates, increased longevity, and greater international migration. The UN produces the official demographic approximations and predictions for every country and all regions of the world. The UNFPA specifically addresses global population by compiling data and statistics regarding migration, fertility, marriage, regional development, urbanization, world population projections, and national population policies.

In November 2012, the UNFPA declared family planning a global human right; however, approximately 12 percent of 15 to 49-year-old women internationally are not afforded access to family planning. This is considered an egregious modern-day human rights infringement. The UNFPA aids various UN bodies like the Commission on Population and Development, and endorses the implementation of the Programme of Action undertaken by the International Conference on Population and Development (IPCD) in 1994. The UNFPA has been successful in urging international cooperation on the issue of securing family planning as a human right, pushing the UN to hold three conferences concerning the issue of population, along with two special sessions of the General Assembly and a summit in 2019 .

The Way Forward

Ultimately, apocalyptic population growth fears are overblown, and as such, draconian population control regulations are unnecessary. We have witnessed progress on an international scale in this area, perhaps most notably with China revoking its infamous, longstanding one-child policy just seven years ago. However, a broader global focus on guaranteeing family planning as a human right remains essential. In the words of economist Julian Simon, “Whatever the rate of population growth is, historically it has been that the food supply increases at least as fast, if not faster.” Since Ehrlich’s initial fear-mongering regarding an overpopulation-induced Armageddon, the planet’s population has more than doubled . However, annually, famine deaths have dropped by millions. Today’s famines are war-induced, not caused by natural resource consumption. As production rose, prices fell and calorie consumption increased, which decreased malnutrition worldwide. In Simon’s words, human ingenuity is the “ ultimate resource .” Therefore, the enactment of heavy-handed population-control regulations is not only abhorrent, but is also irrational and unsupported by scientific evidence.

Human Overpopulation: Still an Issue of Concern?

The jury is still out as to whether the growth of human population is a positive factor or a dominant ill that could spell environmental and social catastrophe

EarthTalk® E - The Environmental Magazine

Dear EarthTalk : Is it true that human overpopulation isn’t such a big issue anymore, as numbers are expected to start declining in a few decades? —Melinda Mason, Boone, Iowa Ever since Thomas Malthus published “An Essay on the Principle of Population” in 1798, positing incorrectly that humans’ proclivity for procreation would exhaust the global food supply within a matter of decades, population growth has been a hot button issue among those contemplating humankind’s future. Indeed our very success going forth and multiplying, paired with our ability to extend our life expectancy, has meant that we are perpetually pushing the limits of the resource base that supports us.

When Malthus was worrying about the planet’s “carrying capacity,” there were only about a billion of us on the planet. Today our population tops seven billion. While better health care and medicine along with advances in food production and access to freshwater and sanitation have allowed us to feed ourselves and stave off many health ills, some so-called Neo-Malthusians believe we may still be heading for some kind of population crash, perhaps triggered or exacerbated by environmental factors related to climate change.

But others are less concerned given projections that world population will likely start to decline once the world’s less developed nations urbanize and start lowering their birth rates, as has already happened in Europe, the U.S., Australia and parts of Asia. For example, Europe’s “fertility rate” between 2005 and 2010 was just 1.53 live births per woman (the standard replacement rate to maintain a stable population is 2.1). Without immigration, Europe’s population would already be shrinking.

Of course, the immigration that continues to fuel population numbers in developed countries is coming from somewhere. Indeed, population numbers are still growing in many of the world’s developing countries, including the world’s most populous nation, China, and its close rival, India. Also fertility rates in Africa continue to be among the highest in the world, as many countries there are growing fast, too. Poverty and health problems due to poor sanitation, lack of access to food and water, the low social status of women and other ills continue to cripple these regions. Overpopulation could plague us indefinitely if fertility rates don’t drop in these areas, especially as they ramp up their Western-style development. Globally, the United Nations estimates that the number of humans populating the planet in 2100 will range from as few as 6.2 billion—almost a billion less than today—to as many as 15.8 billion on the high end. Meanwhile, other researchers confirm the likelihood of world population levels flattening out and starting to decline by 2100 according to the lower UN estimate. To wit, the Austria-based International Institute for Applied Systems Analysis (IIASA) recently unveiled research showing that if the world stabilizes at a fertility rate comparable to that of many European nations today (roughly 1.5), the global human population will be only half of what it is today by the year 2200, and only one-seventh by 2300.

It is difficult to say which way the global population pendulum will swing in centuries to come, given ever-changing cultural, economic and political attitudes and the development demographics they affect. As such the jury is still out as to whether human overpopulation will become a footnote in history or the dominant ill that stands in the way of all other efforts to achieve sustainability and a kinder, gentler world.

Human Overpopulation: Causes and Effects in Developing Countries

This research paper outlines the causes and effects of human overpopulation, focusing in developing countries. The primary cause of this problems includes low mortality rates coupled with high birth rates. The exponential influx in human overpopulation has had negative effects on both the economic stability and environment of the affected countries. In addition to the causes and effects discussed, potential solutions are proposed to assist in the mitigation of the problem.

Over-population is a great Problem for many countries. This research looks into all possible solutions for this problem. World population has jumped from about 2.5 billion in 1951 to 7.8 billion in April 2020 , 212% increase. Over-population has been an issue for many countries especially in Africa, as Africa has the highest fertility rate ,children per woman, and Africans are low on resources especially for those who live in the middle of Africa ,in other words, near the equator, Because of its hot weather and being low on water, it is optimum environment for spreading diseases and droughts which its direct relation to overpopulation was later discovered resulting in lack of resources and slowness of economy development. Human Resources management has important terminology which need to be understood before getting into our main topic: fertility rate is the average children per woman, birth rate is the average number of children born per year and death rate is the number of deaths per year, natural change is the birth rate minus the death rate . Social Scientists have many theories on what causes over-population, Some suggest that poverty is the main cause of over-population as it is seen in most poor countries like in Africa unlike rich countries in Europe. They suggest that families try to overcome their poor condition by having more children. But other scientists argue that it can be correlation and something else is causing both of them. They suggest that it is a high death rates. Also, through comparing between poor Countries and rich Countries, it can be notice that in poor countries, death rates are high as of that most families give birth to many children. There are other suggested causes like lack of education and child labor. Over-population can cause many serious problems especially for poor countries. For example, It can cause lack of water in developing countries because as the population grow, water consumption increases. For countries that do not have a fresh stable water source, This can lead to droughts and lower life expectancy. Also, population growth could cause Extinction of wild life and pollution because forests and natural environments for various animals are cut down to free more space for buildings and cities. green house effect was learned in (CH.2.11) about and learned In (ES.2.10) about the role of plants in stabilizing the carbon dioxide percentage and the role of forest in keeping biodiversity in (BI.2.12). For These reasons, Countries tried to solve this issue, because of its significant impact on the economy and the productivity. Some of these solutions were the “one-child-policy” and “two-child-policy” tried by China to control population growth using the law. The Results of them were very fast. Other places tried to control over-population by focusing on education especially for girls like in Europe in the 19 th century. To conclude, This research will focus on these prior solutions and others and discuss why they work.

Overpopulation is an immensely dangerous problem that does not affect only individual countries but worldwide. It has many causes such as immigration; early marriages, poor medical access, and education are the main reasons to be indicated. While it has many reasons why the earth faces overcrowded, overpopulation's effects are considered a perilous crisis more than itself. In the past, researchers have explored how to stop this rising problem even though; they have tried several ways from mass sterilization to awarding families with no child. None of these approaches worked instead, people tend to have more children and take this dangerous risk. Therefore, depletion of natural resources, rise in pollution, epidemics, and other diseases are the main consequences of overpopulation which this literature review has discussed. Even though scientists and nature activists have argued about the effects of overcrowding on the earth, humankind, and health, there is no right solution taken by us: humans as a creator of this crisis. Furthermore, this research will concentrate on the possible effects of overpopulation on the earth, health, and human kind. Plus, it suggests some possible solutions. Significantly, it illustrates how overpopulation will impact natural resources and human health.

The purpose of this paper is to shed light on the overpopulation issue of India and propose recommendations on how to overcome it. First, the paper summarizes the crucial demographic conditions and where India stands by numbers. Then the article presents the development of the state approach to the issue starting from the early years of independence up to the current policies. It does so by scrutinizing its cultural, economic and social factors and implications of overpopulation and identifies socioeconomic backwardness, early marriages and family norms, lack of adequate health care infrastructure and education as the correlated and interdependent features supporting the trend of overpopulation. The authors come up with three recommendations to tackle the issue – women empowerment, education and industrialization.

The 20th century has seen unprecedented growth of the human population on this planet. While at the beginning of the century the Earth had an estimated 1.6 billion inhabitants, this number grew to 6.1 billion by the end of the century, and further significant growth is a near certainty. This paper tries to summarize what factors lie behind this extraordinary expansion of the human population and what population growth we can expect for the future. It discusses the concept of demographic transition and the preconditions for a lasting secular fertility decline. Recent fertility declines in all parts of the world now make it likely that human population growth will come to an end over the course of this century, but in parts of the developing world significant population growth is still to be expected over the coming decades. The slowing of population growth through declining birth rates, together with still increasing life expectancy, will result in a strong ageing of population age s...

Rapid population growth has been a topic of contestation on a socio-economic, statistical and environmental stance. It has proven to be a great cause for concern in much literature with regards to resource scarcity and the earth’s capacity to withstand the impact thereof, it’s hindrance to economic and social development and it’s threat to global political stability. It is important to note that 80 percent of the world’s population is found in low income countries (Hewitt) and in as much as it has been proven that population growth is exponential in these areas, it has not been resolved that one is poor because they have many children. Quite the opposite has been argued of which recent literature on the relationship between population and development has illustrated. When looking specifically at overpopulation in relation to development, there are two standpoints. The first one sees population growth being the barrier to sustainable development efforts as a whole, and much like the Malthusian Theory it urges control over population growth. The other standpoint denounces claims that overpopulation is the cause of social and economic development problems, but says it is a symptom of it. This essay will be looking at both standpoints so as to critically evaluate whether overpopulation really is the principle cause of development problems.

The Effects of Overpopulation

Global problems affect the life not only of certain individuals but the society in general. One of the global dilemmas that can consequently lead to the severe outcome is overpopulation. The major purpose of the paper is to discuss the problem of overpopulation, highlight the risks and environmental problems, as well as make an accent on the ways of regulation this issue.

As a matter of fact, overpopulation is a modern ecological problem. According to the recent researches, the number of people increases every year with tremendous speed. In 1900, the population reached the point of 1,5 billion of people whereas by 1960 the population has already doubled. Moreover, by 1999, the population doubled again (Pettorelli 543).

Every person consumes a lot of resources, and overpopulation is considered to be a threat. The only solution is birth control and improvement of the quality of life. The human overpopulation takes place in those countries where the population is bigger than food and water resources.

However, birth control encounters many obstacles. Among them are the following, namely negative reaction of the society, the enormous role of religion that encourages having many children, primitive communal forms of living, illiteracy and ignorance, poor development of medicine, and other. Thus, the countries of the third world are the most vulnerable in relation to the overpopulation.

Environmental problem, overpopulation, and underdevelopment are directly linked to a possible threat of lack of the resources in the nearest future. The majority of countries that experience a rapid increase in population have poorly developed agricultural segment.

The solution is to boost the productivity. However, the increase in usage of fertilizers, pesticides, and chemicals leads to a deterioration of the ecological situation and increasing concentrations of substances that are harmful to human food (Coallier 61). The interference of a human being into ecology leads to the lack of water that is good for drinking. In case people do not address the issue, a number of questions will arise, namely:

Landfills and pollution of the surface of the planet;
The destruction of the forests;
Shortage of mineral resources;
Hazardous impact on the marine ecosystem;
Air and water pollution with CO2 emissions (Bourne 375).

The only solution that will mitigate the impact of the over population is the birth control programs. The demographic situation in the Eastern World has already reached the point when the government found it essential to interfere. In the number of states, the measures directed to the reduction of the population were vital for implementation. One of the examples is China, which established the principle one child for one family.

The objective of the government was to control overpopulation. The average number of children who were born in China from one woman decreased from about 5 to 1 (Coallier 83). Thus, the restriction policy was successful, and the government reached the goal. The government encourages families to have one child; however, with the birth of the second baby, the family will be liable to pay a fee.

Throughout the history, the number of people was always controlled by wars and epidemics. Every time the number of people decreased, the society experienced rapid development. Nevertheless, nowadays, the society has already gained a significant experience that can be used in the treatment of different diseases. Thus, there are almost no factors that would significantly decrease the number of people.

In conclusion, it should be stressed that the situation regarding the overpopulation demands the solution. The issue should receive the priority not only on the governmental but global levels as well. Overpopulation can lead to severe consequences and become the reason for the destruction of the planet and humanity.

The world population explosion: causes, backgrounds and projections for the future

J. van bavel.

Centre for Sociological Research / Family & Population Studies (FaPOS), Faculty of Social Sciences, University of Leuven, Parkstraat 45 bus 3601, 3000 Leuven, Belgium.

At the beginning of the nineteenth century, the total world population crossed the threshold of 1 billion people for the first time in the history of the homo sapiens sapiens. Since then, growth rates have been increasing exponentially, reaching staggeringly high peaks in the 20th century and slowing down a bit thereafter. Total world population reached 7 billion just after 2010 and is expected to count 9 billion by 2045. This paper first charts the differences in population growth between the world regions. Next, the mechanisms behind unprecedented population growth are explained and plausible scenarios for future developments are discussed. Crucial for the long term trend will be the rate of decline of the number of births per woman, called total fertility. Improvements in education, reproductive health and child survival will be needed to speed up the decline of total fertility, particularly in Africa. But in all scenarios, world population will continue to grow for some time due to population momentum. Finally, the paper outlines the debate about the consequences of the population explosion, involving poverty and food security, the impact on the natural environment, and migration flows.

Key words: Fertility, family planning, world population, population growth, demographic transition, urbanization, population momentum, population projections.

Introduction

In the year 1900, Belgium and the Philippines had more or less the same population, around 7 million people. By the year 2000, the population of the Western European monarchy had grown to 10 million citizens, while the South East Asian republic at the turn of the century already counted 76 million citizens. The population of Belgium has since then exceeded 11 million citizens, but it is unlikely that this number will rise to 12 million by the year 2050. The population of the Philippines on the other hand will continue to grow to a staggering 127 million citizens by 2050, according to the demographic projections of the United Nations (UN 2013).

The demographic growth rate of the Philippines around the turn of the century (2% a year) has already created enormous challenges and is clearly unsustainable in the long term: such growth implies a doubling of the population every 35 years as a consequence of which there would be 152 million people by 2035, 304 million by 2070, and so on. Nobody expects such a growth to actually occur. This contribution will discuss the more realistic scenarios for the future.

Even the rather modest Belgian demographic growth rate around the turn of this century (0.46%) is not sustainable in the long term. In any case, it exceeds by far the average growth rate of the human species (homo sapiens sapiens) that arose in Africa some 200.000 years ago. Today, earth is inhabited by some 7 billion people. To achieve this number in 200.000 years, the average yearly growth rate over this term should have been around 0.011% annually (so 11 extra human beings per 1.000 human beings already living on earth). The current Belgian growth rate would imply that our country would have grown to 7 billion in less than 1500 years.

The point of this story is that the current growth numbers are historically very exceptional and untenable in the long term. The demographic growth rates are indeed on the decline worldwide and this paper will attempt to explain some of the mechanisms behind that process. That doesn’t change the fact, however, that the growth remains extraordinarily high and the decline in some regions very slow. This is especially the case in Sub Saharan Africa. In absolute numbers, the world population will continue to grow anyway for quite some time as a result of demographic inertia. This too will be further clarified in this paper.

The evolution of the world population in numbers

In order to be sustainable, the long term growth rate of the population should not differ much from 0%. That is because a growth rate exceeding 0% has exponential implications. In simple terms: if a combination of birth and growth figures only appears to cause a modest population growth initially, then this seems to imply an explosive growth in the longer term.

Thomas R. Malthus already acquired this point of view by the end of the 18th century. In his famous “Essay on the Principle of Population” (first edition in 1789), Malthus argues justly that in time the growth of the population will inevitably slow down, either by an increase of the death rate or by a decrease of the birth rate. On a local scale, migration also plays an important role.

It is no coincidence that Malthus’ essay appeared in England at the end of the 18th century. After all, the population there had started to grow at a historically unseen rate. More specifically the proletariat had grown immensely and that worried the intellectuals and the elite. Year after year, new demographic growth records were recorded.

At the beginning of the 19th century, the number of 1 billion people was exceeded for the first time in history. Subsequently growth accelerated and the number of 2 billion people was already surpassed around 1920. By 1960, another billion had been added, in 40 instead of 120 years time. And it continued to go even faster: 4 billion by 1974, 5 billion by 1987, 6 billion by 1999 and 7 billion in 2011 ( Fig. 1 ).

This will certainly not stop at the current 7 billion. According to the most recent projections by the United Nations, the number of 8 billion will probably be exceeded by 2025, and around 2045 there will be more than 9 billion people 1 . The further one looks into the future, the more uncertain these figures become, and with demography on a world scale one must always take into account a margin of error of a couple of tens of millions. But according to all plausible scenarios, the number of 9 billion will be exceeded by 2050.

Demographic growth was and is not equally distributed around the globe. The population explosion first occurred on a small scale and with a relatively moderate intensity in Europe and America, more or less between 1750 and 1950. From 1950 on, a much more substantial and intensive population explosion started to take place in Asia, Latin America and Africa ( Fig. 2 ). Asia already represented over 55% of the world population in 1950 with its 1.4 billion citizens and by the year 2010 this had increased to 4.2 billion people or 60%. Of those people, more than 1.3 billion live in China and 1.2 billion in India, together accounting for more than one third of the world population.

An external file that holds a picture, illustration, etc.
Object name is FVVinObGyn-5-281-291-g002.jpg

In the future, the proportion of Asia will come down and that of Africa will increase. Africa was populated by some 230 million people around 1950, or 9% of the world population. In 2010 there were already more than 1 billion Africans or 15% of the world population. According to UN projections, Africa will continue to grow at a spectacular rate up to 2.2 billion inhabitants in 2050 or 24% of the world population. The proportion of Europe, on the other hand, is evolving in the opposite direction: from 22% of the world population in 1950, over 11% in 2010 to an expected mere 8% in 2050. The population of Latin America has grown and is growing rapidly in absolute terms, but because of the strong growth in Asia and especially Africa, the relative proportion of the Latin American population is hardly increasing (at most from 6 to 8%). The proportion of the population in North America, finally, has decreased slightly from 7 to 5% of the world population.

What these figures mainly come down to in practice is that the population size in especially the poor countries is increasing at an unprecedented rate. At the moment, more than 5.7 billion people, or more than 80% of humanity, are living in what the UN categorise as a developing country. By 2050, that number would – according to the projections – have increased to 8 billion people or 86% of the world population. Within this group of developing countries, the group of least developed countries, the poorest countries so to speak, is growing strongly: from 830 million now, up to an expected 1.7 billion in 2050. This comprises very poor countries such as Somalia, Sudan, Liberia, Niger or Togo in Africa; Afghanistan, Bangladesh or Myanmar in Asia; and Haiti in the Caribbean.

The growth of the world population goes hand in hand with global urbanisation: while around the year 1950 less than 30% of people lived in the cities, this proportion has increased to more than 50%. It is expected that this proportion will continue to grow to two thirds around 2050. Latin America is the most urbanised continent (84%), closely followed by North America (82%) and at a distance by Europe (73%). The population density has increased intensely especially in the poorest countries: from 9 people per square km in 1950 to 40 people per square km in 2010 (an increase by 330%) in the poorest countries, while this figure in the rich countries increased from 15 to 23 people per square km (a 50% growth). In Belgium, population density is 358 people per square km and in the Netherlands 400 people per square km; in Rwanda this number is 411, in the Palestinian regions 666 and in Bangladesh an astonishing 1050.

Although the world population will continue to grow in absolute figures for some time – a following paragraph will explain why – the growth rate in percentages in all large world regions is decreasing. In the richer countries, the yearly growth rate has already declined to below 0.3%. On a global scale, the yearly growth rate of more than 2% at the peak around 1965 decreased to around 1% now. A further decline to less than 0.5% by 2050 is expected. In the world’s poorest countries, the demographic growth is still largest: at present around 2.2%. For these countries, a considerable decrease is expected, but the projected growth rate would not fall below 1.5% before 2050. This means, as mentioned above, a massive growth of the population in absolute figures in the world’s poorest countries.

Causes of the explosion: the demographic transition

The cause of, first, the acceleration and, then, the deceleration in population growth is the modern demographic transition: an increasingly growing group of countries has experienced a transition from relatively high to low birth and death rates, or is still in the process of experiencing this. It is this transition that is causing the modern population explosion. Figure 3 is a schematic and strongly simplified representation of the modern demographic transition.

In Europe, the modern demographic transition started to take place in the middle of the 18th century. Until then, years of extremely high death rates were quite frequent. Extremely high crisis mortality could be the consequence of epidemic diseases or failed harvests and famine, or a combination of both. As a consequence of better hygiene and a better transportation infrastructure (for one, the canals and roads constructed by Austria in the 18th century), amongst other reasons, crisis mortality became less and less frequent. Later on in the 19th century, child survival began to improve. Vaccination against smallpox for example led to an eradication of the disease, with the last European smallpox pandemic dating from 1871. This way, not only the years of crisis mortality became less frequent, but also the average death rate decreased, from an average 30 deaths per 1000 inhabitants in the beginning of the 19th century to around 15 deaths per 1000 citizens by the beginning of the 20th century. In the meantime, the birth rate however stayed at its previous, high level of 30-35 births per 1000 inhabitants.

The death rate went down but the birth rate still didn’t: this caused a large growth in population. It was only near the end of the nineteenth century (a bit earlier in some countries, later in others) that married couples in large numbers started to reduce their number of children. By the middle of the 20th century, the middle class ideal of a two children household had gained enormous popularity and influence. The reaction by the Church, for example in the encyclical Humanae Vitae (1968), came much too late to bring this evolution to a halt.

As a consequence of widespread family planning – made even easier in the sixties by modern hormonal contraceptives – the birth rate started declining as well and the population tended back towards zero growth. Nowadays the end of this transition process has been more than achieved in all European countries, because the fertility has been below replacement level for several decades (the replacement level is the fertility level that would in the long term lead to a birth rate identical to the death rate, if there would be no migration) 2 .

That the population explosion in the developing countries since the second half of the 20th century was so much more intense and massive, is a consequence of the fact that in those countries, the process of demographic transition occurred to a much more extreme extent and on a much larger scale. On the one hand, mortality decreased faster than in Europe. After all, in Europe the decline in mortality was the result of a gradual understanding of the importance of hygiene and afterwards the development of new medical insights. These insights of course already existed at the start of the demographic transitions in Asian, Latin American and African regions, whereby the life expectancy in these regions could grow faster. On the other hand, the total fertility – the average number of children per woman – at the start of the transition was a lot higher in many poor regions than it initially was in Europe. For South Korea, Brasil and the Congo, for example, the total fertility rate shortly after the Second World War (at the start of their demographic transition) is estimated to be 6 children per woman. In Belgium this number was close to 4.5 children per woman by the middle of the nineteenth century. In some developing regions, the fertility and birth rate decreased moderately to very fast, but in other regions this decline took off at an exceptionally sluggish pace – this will be further explained later on. As a consequence of these combinations of factors, in most of these countries the population explosion was much larger than it had been in most European countries.

Scenarios for the future

Nonetheless, the process of demographic transition has reached its second phase in almost all countries in the world, namely the phase of declining fertility and birth rates. In a lot of Asian and Latin American countries, the entire transition has taken place and the fertility level is around or below the replacement level. South Korea for example is currently at 1.2 children per woman and is one of the countries with the lowest fertility levels in the world. In Iran and Brasil the fertility level is currently more or less equal to Belgium’s, that is 1.8 to 1.9 children per woman.

Crucial to the future evolution of the population is the further evolution of the birth rate. Scenarios for the future evolution of the size and age of the population differ according to the hypotheses concerning the further evolution of the birth rate. The evolution of the birth rate is in turn dependent on two things: the further evolution of the total fertility rate (the average number of children per woman) in the first place and population momentum in the second. The latter is a concept I will later on discuss in more detail. The role of the population momentum is usually overlooked in the popular debates, but is of utmost importance in understanding the further evolution of the world population. Population momentum is the reason why we are as good as certain that the world population will continue to grow for a while. The other factor, the evolution of the fertility rate, is much more uncertain but of critical importance in the long term. The rate at which the further growth of the world population can be slowed down is primarily dependent on the extent to which the fertility rates will continue to decline. I will further elaborate on this notion in the next paragraph. After that, I will clarify the notion of population momentum.

Declining fertility

Fertility is going down everywhere in the world, but it’s going down particularly slowly in Africa. A further decline remains uncertain there. Figure 4 shows the evolution per world region between 1950 and 2010, plus the projected evolution until 2050. The numbers before 2010 illustrate three things. First of all, on all continents there is a decline going on. Secondly, this decline is not equal everywhere. And thirdly: the differences between the continents remain large in some cases. Asia and Latin America have seen a similar decline in fertility: from 5.9 children per woman in 1950 to 2.5 at the start of the 21st century. Europe and North America had already gone through the largest part of their demographic transition by the 1950’s. Their fertility level has been below replacement levels for years. Africa has indeed seen a global decrease of fertility, but the average number of children is still at an alarmingly high level: the fertility merely decreased from 6.7 to 5.1 children per woman.

These continental averages hide a huge underlying diversity in fertility paths. Figure 5 attempts to illustrate this for a number of countries. Firstly let us consider two African countries: the Congo and Niger. As was often the case in Europe in the 19th century, fertility was first on the rise before it started declining. In the Congo this decrease was more extensive, from around 6 children in 1980 to 4 children per woman today, and a further decline to just below three is expected in the next thirty years. Niger is the country where the fertility level remains highest: from 7 it first rose to an average of just below 8 children per woman in the middle of the 1980’s, before decreasing to just above 6.5 today. For the next decades a decline to 4 children per woman is expected. But that is not at all certain: it is dependent on circumstances that will be further explained in a moment. The demographic transition is after all not a law of nature but the result of human actions and human institutions.

Around 1950, Pakistan and Iran had more or less the same fertility level as Niger, but both countries have seen a considerable decline in the meantime. In Pakistan the level decreased slowly to the current level of 3 children per woman. In Iran the fertility decreased more abruptly, faster and deeper to below the replacement level – Iran today has one of the lowest fertility levels in the world, and a further decline is expected. The Iranian Revolution of 1978 played a crucial role in the history of Iran (Abassi-Shavazi et al., 2009): it brought better education and health care, two essential ingredients for birth control.

Brasil was also one of the countries with very high fertility in the 1950’s – higher than the Congo, for example. The decrease started earlier than in Iran but happened more gradually. Today both countries have the same total fertility, below the replacement level.

Child mortality, education and family planning

Which factors cause the average number of children to go down? The literature concerning explanations for the decrease in fertility is vast and complex, but two factors emerge as crucial in this process: education and child survival.

Considering child survival first: countries combining intensive birth control with very high child mortality are simply non-existent. The statistical association between the level of child mortality and fertility is very tight and strong: in countries with high child mortality, fertility is high, and vice versa. This statistical correlation is very strong because the causal relation goes in both directions; with quick succession of children and therefore a lot of children to take care for, the chances of survival for the infants are lower than in those families with only a limited number of children to take care of – this is a fortiori the case where infrastructure for health care is lacking. A high fertility level thus contributes to a high child mortality. And in the other direction: where survival chances of children improve, the fertility will go down because even those households with a lower number of children have increasing confidence in having descendants in the long term.

It is crucial to understand that the decline in child mortality in the demographic transition always precedes the decline in fertility. Men, women and families cannot be convinced of the benefits of birth control if they don’t have confidence in the survival chances of their children. Better health care is therefore essential, and a lack of good health care is one of the reasons for a persistently high fertility in a country like Niger.

Education is another factor that can cause a decline in fertility. This is probably the most important factor, not just because education is an important humanitarian goal in itself (apart from the demographic effects), but also because with education one can kill two birds with one stone: education causes more birth control but also better child survival (recently clearly demonstrated by Smith-Greenaway (2013), which in its turn will lead to better birth control. The statistical correlation between level of education and level of fertility is therefore very strong.

Firstly, education enhances the motivation for birth control: if parents invest in the education of their children, they will have fewer children, as has been demonstrated. Secondly, education promotes a more forward-looking lifestyle: it will lead people to think on a somewhat longer term, to think about tomorrow, next week and next month, instead of living for the day. This attitude is necessary for effective birth control. Thirdly, education also increases the potential for effective contraception, because birth control doesn’t just happen, especially not when efficient family planning facilities are not or hardly accessible or when there are opposing cultural or family values.

The influence of education on birth control has been demonstrated in a vast number of studies (James et al., 2012). It starts with primary education, but an even larger effect can be attained by investment in secondary education (Cohen, 2008). In a country like Niger, for example, women who didn’t finish primary school have on average 7.8 children. Women who did finish primary school have on average 6.7 children, while women who finished secondary school “only” have 4.6 children ( Fig. 6 ). The fertility of Niger would be a lot lower if more women could benefit from education. The tragedy of that country is that too many people fall in the category of those without a degree of primary school, with all its demographic consequences.

One achieves with education therefore a plural beneficial demographic effect on top of the important objective of human emancipation in itself. All this is of course not always true but depends on which form of “education”; I assume that we’re talking about education that teaches people the knowledge and skills to better take control of their own destiny.

It is one thing to get people motivated to practice birth control but obtaining actual effective contraception is quite another matter. Information concerning the efficient use of contraceptives and increasing the accessibility and affordability of contraceptives can therefore play an important role. There are an estimated 215 million women who would want to have contraception but don’t have the means (UNFPA, 2011). Investments in services to help with family planning are absolutely necessary and could already have great results in this group of women. But it’s no use to put the cart before the horse: if there is no intention to practice birth control, propaganda for and accessibility of contraception will hardly have any effect, as was demonstrated in the past. In Europe the lion’s share of the decline in fertility was realized with traditional methods, before the introduction of hormonal contraception in the sixties. There is often a problem of lack of motivation for birth control on the one hand, as a result of high child mortality and low schooling rates, and a lack of power in women who may be motivated to limit fertility but are confronted with male resistance on the other (Blanc, 2011; Do and Kurimoto, 2012). Empowerment of women is therefore essential, and education can play an important role in that process as well.

Population momentum

Even if all the people would suddenly practice birth control much more than is currently considered possible, the world population would still continue to grow for a while. This is the consequence of population momentum, a notion that refers to the phenomenon of demographic inertia, comparable to the phenomenon of momentum and inertia in the field of physics. Demographic growth is like a moving train: even when you turn off the engine, the movement will continue for a little while.

The power and direction of population momentum is dependent on the age structure of the population. Compare the population pyramids of Egypt and Germany ( Fig. 7 ). The one for Egypt has a pyramidal shape indeed, but the one for Germany looks more like an onion. As a consequence of high birth rates in the previous decades, the largest groups of Egyptians are to be found below the age of forty; the younger, the more voluminous the generation. Even if the current and future generations of Egyptians would limit their fertility strongly (as is indeed the case), the birth rate in Egypt would still continue to rise for quite some time, just because year after year more and more potential mothers and fathers reach the fertile ages. Egypt therefore clearly has a growth momentum.

Object name is FVVinObGyn-5-281-291-g007.jpg

Germany on the other hand has a negative or shrinking momentum: even if the younger generations of Germans would have a larger num ber of children than the generation of their own parents, the birth rate in Germany would still continue to decrease because fewer and fewer potential mothers and fathers reach the fertile ages.

The population momentum on a global scale is positive: even if fertility would decrease overnight to the replacement level, the world population would continue to grow with 40% (from 7 billion to 9.8 billion). Only the rich countries have a shrinking momentum, that is -3%. For Europe the momentum is -7%. The population momentum for the poorest countries in the world is +44%, that of Sub Saharan Africa +46% (Espenshade et al., 2011).

Consequences of the population explosion

The concerns about the consequences of population explosion started in the sixties. Milestone publications were the 1968 book The Population bomb by biologist Paul Ehrlich, the report of the Club of Rome from 1972 (The Limits to Growth) and the first World Population Plan of Action of the UN in 1974 among others.

In the world population debate, the general concerns involve mainly three interconnected consequences of the population explosion: 1) the growing poverty in the world and famine; 2) the exhaustion and pollution of natural resources essential to human survival; and 3) the migration pressure from the poor South to the rich North (Van Bavel, 2004).

Poverty and famine

The Malthusian line of thought continues to leave an important mark on the debate regarding the association between population growth and poverty: Malthus saw an excessive population growth as an important cause of poverty and famine. Rightfully this Malthusian vision has been criticized a lot. One must after all take the reverse causal relation into account as well: poverty and the related social circumstances (like a lack of education and good health care for children) contribute to high population growth as well.

Concerning famine: the production of food has grown faster since 1960 than the world population has, so nowadays the amount of food produced per person exceeds that which existed before the population explosion (Lam, 2011). The problem of famine isn’t as much an insufficient food production as it is a lack of fair distribution (and a lack of sustainable production, but that’s another issue). Often regions with famine have ecological conditions permitting sufficient production of food, provided the necessary investments in human resources and technology are made. The most important cause of famine is therefore not the population explosion. Famine is primarily a consequence of unequal distribution of food, which in turn is caused by social-economic inequality, lack of democracy and (civil) war.

Poverty and famine usually have mainly political and institutional causes, not demographic ones. The Malthusian vision, that sees the population explosion as the root of all evil, therefore has to be corrected ( Fig. 8 ). Rapid population growth can indeed hinder economical development and can thus pave the way for poverty. But this is only part of the story. As mentioned, poverty is also an underlying cause of rapid population growth. Social factors are at the base of both poverty and population growth. It’s those social factors that require our intervention: via investments in education and (reproductive) health care.

Impact on the environment

The impact of the population explosion on the environment is unquestionably high, but the size of the population represents only one aspect of this. In this regard it can be useful to keep in mind the simple I=PAT scheme: the ecological footprint or impact on the environment (I) can be regarded as the product of the size of the population (P), the prosperity or consumption level (A for affluence) and the technology used (T). The relationship between each of these factors is more complex than the I=PAT scheme suggests, but in any case the footprint I of a population of 1000 people is for example dependent on how many of those people drive a car instead of a bike, and of the emission per car of the vehicle fleet concerned.

The ecological footprint of the world population has increased tremendously the past decades and the growth of the world population has obviously played an important role in this. The other factors in the I=PAT scheme have however played a relatively bigger role than the demographic factor P. The considerable increase in the Chinese ecological footprint of the past decades for example, is more a consequence of the increased consumption of meat than of population growth (Peters et al., 2007; Liu et al., 2008). The carbon dioxide emission of China grew by 82% between 1990 and 2003, while the population only increased by 11% in that same period. A similar story exists for India: the population grew by less than 23% between 1990 and 2003, while the emission of carbon dioxide increased by more than 83% (Chakravarty et al., 2009). The consumption of water and meat in the world is increasing more rapidly than the population 3 . The consumption of water per person is for example threefold higher in the US than in China (Hoekstra and Chapagain, 2007). The African continent has at present the same number of inhabitants as Europe and North America together, over 1 billion. But the total ecological footprint of Europeans and Americans is many times higher than that of Africans (Ewing et al., 2010). Less than 18% of the world population is responsible for over 50% of the global carbon dioxide emission (Chakravarty et al., 2009).

If we are therefore concerned about the impact of the world population on the environment, we can do something about it immediately by tackling our own overconsumption: it’s something we can control and it has an immediate effect. In contrast, we know of the population growth that it will continue for some time anyhow, even if people in poor countries would practice much more birth control than we consider possible at present.

The population explosion has created an increasing migration pressure from the South to the North – and there is also important migration within and between countries in the South. But here as well the message is: the main responsibility doesn’t lie with the population growth but with economic inequality. The primary motive for migration was and is economic disparity: people migrate from regions with no or badly paid labour and a low standard of living to other regions, where one hopes to find work and a higher standard of living (Massey et al., 1993; Hooghe et al., 2008; IMO, 2013). Given the permanent population growth and economical inequality, a further increasing migration pressure is to be expected, irrespective of the national policies adopted.

It is sometimes expected that economic growth and increasing incomes in the South will slow down the migration pressure, but that remains to be seen. After all, it isn’t usually the poorest citizens in developing countries that migrate to rich countries. It is rather the affluent middle class in poor countries that have the means to send their sons and daughters to the North – an investment that can raise a lot of money via remittances to the families in the country of origin (IMO, 2013). There is after all a considerable cost attached to migration, in terms of money and human capital. Not everyone can bear those costs: to migrate you need brains, guts and money. With growing economic development in poor countries, an initial increase in migration pressure from those countries would be expected; the association between social-economic development and emigration is not linearly negative but follows the shape of a J turned upside down: more emigration at the start of economic development and a decline in emigration only with further development (De Haas, 2007).

7 Billion and counting… What is to be done?

A world population that needed some millennia before reaching the number of 1 billion people, but then added some billions more after 1920 in less than a century: the social, cultural, economic and ecological consequences of such an evolution are so complex that they can lead to fear and indifference at the same time. What kind of constructive reaction is possible and productive in view of such an enormous issue?

First of all: we need to invest in education and health care in Africa and elsewhere, not just as a humanitarian target per se but also because it will encourage the spread of birth control. Secondly, we need to encourage and support the empowerment of women, not just via education but also via services for reproductive health. This has triple desirable results for demographics: it will lead to more and more effective birth control, which in itself has a positive effect on the survival of children, which in turn again facilitates birth control.

Thirdly: because of the positive population momentum, the world population will certainly continue to grow in absolute figures, even though the yearly growth rate in percentages is already on the decline for several years. The biggest contribution we could make therefore, with an immediate favourable impact for ourselves and the rest of the world, is to change our consumption pattern and deal with the structural overconsumption of the world’s richest countries.

(1) Unless otherwise specified, all figures in this paragraph are based on the United Nations World Population Prospects, the 2012 Revision, http://esa.un.org/wpp/ . Concerning projections for the future, I reported the results of the Medium Variant. Apart from this variant, there are also high and low variants (those relying on scenarios implying respectively an extremely high and extremely low growth of the population) and a variant in which the fertility rates are fixed at the current levels. It is expected that the actual number will be somewhere between the highest and lowest variant and will be closest to the medium variant. That’s why I only report this latter value.

(2) In demography, the term «fertility» refers to the actual number of live births per women. By contrast, the term fecundity refers to reproductive capacity (irrespective of actual childbearing), see Habbema et al. (2004).

IELTS Overpopulation Essay - Sample Answer

Many countries of the world are currently experiencing problems caused by rapidly growing populations in urban areas, and both governments and individuals have a duty to find ways to overcome these problems.

Overpopulation can lead to overcrowding and poor quality housing in many large cities. Poorly heated or damp housing could cause significant health problems, resulting in illness, such as bronchitis or pneumonia. Another serious consequence of overcrowding is a rising crime rate as poor living conditions may lead young people in particular to take desperate measures and turn to crime or drugs.

In terms of solutions, I believe the government should be largely responsible. Firstly, it is vital that the state provides essential housing and healthcare for all its citizens. Secondly, setting up community projects to help foster more community spirit and help keep young people off the street is a good idea. For example, youth clubs or evening classes for teenagers would keep them occupied. Finally, more effective policing of inner city areas would also be beneficial.

Naturally, individuals should also try to address these problems. One way is to put pressure on the government to ensure they tackle the problems by, for instance, forming action groups to lobby the government and request intervention and adequate funding. They could also form Neighbourhood Watch areas to try and help reduce the high levels of crime.

Therefore, it is clear that the problems caused by overpopulation in urban areas are very serious. Yet if governments and individuals share a collective responsibility, then it may well become possible to offer some solutions.

Short Essay on Overpopulation (250 – 300 Words)

Introduction

Overpopulation is a global issue that affects our lives and will continue to do so until some action is taken. To put it in simple terms, it is a situation where the number of people living in an area is significantly higher than the amount of resources available to them. As population growth continues to spiral and more people are born than die in a given area, overpopulation inevitably increases.

Consequences of Overpopulation

The consequences of overpopulation are far-reaching and deadly. In densely populated cities, finite resources become increasingly scarce as industrialization and urbanization increase. This causes competition over resources and pressure on water, energy, and food supplies. Stressful living conditions only add to the problem as people battle overcrowding in housing as well as in workplaces and public spaces. This struggle to survive can lead to mental and physical health problems, aggression, and crime.

Impact of Overpopulation on the Environment

The environment also suffers greatly under overpopulation. With more people consuming resources and creating waste, there is an increased demand for space, energy, and materials. This often leads to habitat destruction, air and water pollution, and the depletion of natural resources. It is also believed that the human population is partly responsible for climate change as a result of the increase in emissions from transport, agriculture, and industry.

Overpopulation is an urgent, complex, and universal issue that needs to be tackled now to ensure our planet’s future. We must prioritize our wellbeing of us while carefully managing our resources so that no one is disproportionately affected by the consequences of human population growth.

Long Essay on Overpopulation (500 Words)

The global population has increased exponentially over the past century. Overpopulation is a major concern for the world, as it has a wide range of impacts on the environment, economy, health, and more. It is therefore important to understand the various implications of overpopulation and take steps to mitigate them.

Impact of Overpopulation on Global Scale

On a global scale, overpopulation can create large-scale environmental issues. As the number of people on the planet increases, so does the number of resources required to sustain them. This can lead to deforestation as more trees are cut down to provide materials for housing, and increased pollution due to additional waste being created. In addition, it creates the issue of food insecurity as more people are competing for access to limited resources.

Impact of Overpopulation on National Level

On a national level, overpopulation can lead to economic problems. As the population increases, it becomes more difficult to produce enough jobs and create enough income opportunities to support everyone. This in turn can lead to higher unemployment, higher taxes, and poorer living standards. In addition, due to population pressure, public services such as healthcare, transportation, and education can suffer from underinvestment, leading to poorer quality and inaccessibility for those who need it the most.

Impact of Overpopulation on Personal Level

On a personal level, being part of an overpopulated society can have many negative impacts. Crowding can lead to greater stress due to reduced personal space, more noise and air pollution, and decreased access to recreational areas. In addition, it can lead to greater competition for resources such as food and housing, resulting in rising prices and poverty rates.

Solutions for Overpopulation

While overpopulation has serious implications for our planet, there are steps we can take to mitigate this issue. Governments can implement and promote family planning programs to help families have better access to modern contraception and reproductive health care. In addition, comprehensive sex education can be used to promote responsible and informed decision-making on the part of individuals. On an environmental level, we can take steps to reduce our consumption of resources, adopt cleaner energy sources, and implement programs that promote environmental protection.

Overpopulation in India

India is one of the most populous countries in the world, with a population of more than 140 crore people. The country is struggling to meet the needs of its rapidly growing population. Overpopulation is an issue that India needs to address urgently. This can be done through education and better access to family planning services. Awareness campaigns need to be conducted to educate people about the consequences of overpopulation. Furthermore, the government needs to provide incentives for family planning and reproductive health care needs to be made accessible to everyone.

Overpopulation is a global issue with a wide range of societal and environmental implications. It is therefore important to understand the various impacts of overpopulation and to take steps to reduce, mitigate, and address them. With the proper solutions in place, it is possible to ensure that our planet can sustain its population in a way that is healthy and beneficial to all.

I hope the above-provided essay on overpopulation will be helpful for everyone to know the impact of the increasing population on our planet.

29 May 2024 · Amir Hossein Karbasi , Hao Yang , Saiedeh Razavi · Edit social preview

In transportation networks, intersections pose significant risks of collisions due to conflicting movements of vehicles approaching from different directions. To address this issue, various tools can exert influence on traffic safety both directly and indirectly. This study focuses on investigating the impact of adaptive signal control and connected and automated vehicles (CAVs) on intersection safety using a deep reinforcement learning approach. The objective is to assess the individual and combined effects of CAVs and adaptive traffic signal control on traffic safety, considering rear-end and crossing conflicts. The study employs a Deep Q Network (DQN) to regulate traffic signals and driving behaviors of both CAVs and Human Drive Vehicles (HDVs), and uses Time To Collision (TTC) metric to evaluate safety. The findings demonstrate a significant reduction in rear-end and crossing conflicts through the combined implementation of CAVs and DQNs-based traffic signal control. Additionally, the long-term positive effects of CAVs on safety are similar to the short-term effects of combined CAVs and DQNs-based traffic signal control. Overall, the study emphasizes the potential benefits of integrating CAVs and adaptive traffic signal control approaches in order to enhance traffic safety. The findings of this study could provide valuable insights for city officials and transportation authorities in developing effective strategies to improve safety at signalized intersections.

Introduction

Major impacts on the environment resulting from overpopulation, works cited.

Overpopulation may be described as a situation where a habitat holds a larger number of organisms than it should. The human population has been increasing at extreme rates in last few decades with an estimated three births every day (Connor 2006). Overpopulation has continued affecting the environment negatively over these years. Many human activities are not environment friendly and overpopulation does not make the situation any better.

One of the major ways in which overpopulations affects the environment is through water pollution. As many people move to urban areas to seek employment, the amount of sewage waste tends to increase. Such wastes are carelessly disposed off such that they finally find their way into water bodies in their untreated condition.

Some of the main contributors of water pollution are industries and open mines whose waste water contains chemical substances and other materials such as heavy metals which cannot be purified. Overexploitation in oceans through overfishing causes imbalance in the ecosystem of the coastal areas and results to lower populations of fish and other aquatic organisms (Stancheva 2003).

Eventually, all these wastes and sediments find their way into the ocean and since the ocean is important in regulating climate, the overall climate is affected which may lead to economical problems. In addition, the ocean helps to prevent global warming through absorption of some percentage of the carbon dioxide released into the atmosphere by human activities. Destruction of the ocean through overexploitation, therefore, limits this function.

Besides polluting the water, there is also the problem of overconsumption which limits the supply of this precious commodity. Lack of adequate water also affects the environment since water is essential in maintaining a balanced ecosystem through its use by plants and animals (Vinelli 2003).

Degradation of soil is another major impact of overpopulation. As the population increases, so does the demand for food production to cater for the growing population. This then leads to exploitation of lands that are not suitable for cultivation such as hilly areas and hilly lands whose cultivation leads to erosion and consequent loss of nutrients.

This need for more land for cultivation leads to certain agricultural practices that are not environment friendly such as slash-and-burn cultivation which lead to deforestation. Similarly, overpopulation calls for higher energy production. This leads to exploitation of wood for fuel production and hence resulting to deforestation.

Other primary causes of deforestation are construction of roads and residential houses to cater for the increasing population. The general impact of all the effects mentioned above is the decrease in biodiversity (Fears 2009). As the natural habitats are destroyed, many wildlife species have been displaced and many died due to changes in the environment resulting from pressure due to human overexploitation of the environment.

All of these issues indicate that the natural resources that humans ignore and misuse are of great importance to them. Some of these impacts on the environment resulting from human overexploitation of natural resources may be permanent or last for long periods of time (Nahle 2003).

If these trends continue, the environmental conditions will intensify since it is no doubt that the human population will continue increasing in the recent past. Sustainable approaches should, therefore, be taken to conserve the natural resources in order to counteract these adverse impacts

The Evolution and Impact of Slave Codes in American History

This essay about the history and impact of slave codes in America explores their origins in the colonial era and their role in perpetuating the subjugation of African Americans. It examines how these laws enforced racial hierarchy and dehumanization, while also highlighting the persistent resistance from enslaved individuals and abolitionists. The legacy of slave codes, extending into the era of Jim Crow, serves as a powerful reminder of the resilience and struggle for justice and equality.

How it works

In the vast expanse of American history, few narratives are as deeply interwoven or as profoundly marked by suffering as the saga of slave codes. These legal frameworks, born from exploitation and hardened in the fires of oppression, carved a bleak path through the nation’s past, leaving a significant impact on its present and future. From their inception in the early colonial period to their ultimate dismantling in the turbulent aftermath of the Civil War, slave codes stood as both a testament to human cruelty and a clarion call for justice.

The origins of slave codes in America can be traced back to the earliest days of European colonization, when the seeds of slavery were planted in the fertile soil of the New World. In the absence of established laws or moral boundaries, colonial settlers devised a patchwork of regulations to control the lives of enslaved Africans, treating them not as human beings but as property to be bought, sold, and discarded at will.

As slavery took hold and spread across the Southern colonies, the need for more comprehensive and enforceable legal structures to maintain control over the enslaved population grew. Consequently, slave codes emerged, codifying and reinforcing the power dynamics inherent in the master-slave relationship. These codes dictated every aspect of slave life, from daily routines to the brutal punishments inflicted on those who dared to defy their masters.

Central to the ideology of slave codes was the notion of racial hierarchy, which asserted the inherent inferiority of Africans and justified their subjugation based solely on skin color. Enshrined in law and enforced with ruthless precision, this insidious ideology formed the foundation of slavery, perpetuating a cycle of dehumanization and exploitation that would endure for centuries.

Despite their cruelty and injustice, slave codes could not extinguish the spark of resistance that burned within the hearts of the enslaved. From the plantations of the Deep South to the bustling cities of the North, enslaved individuals and abolitionists waged a relentless struggle against the bonds of slavery, challenging the legitimacy of slave codes and demanding recognition of their inherent humanity.

The legacy of slave codes resonates through the annals of American history, leaving a lasting imprint on the nation’s collective consciousness. Even after the abolition of slavery, the specter of racial discrimination and inequality continued to haunt the corridors of power, manifesting in the form of Jim Crow laws and other schemes designed to perpetuate the subjugation of African Americans.

Ultimately, the story of slave codes is not merely a tale of oppression and injustice but also one of resilience and resistance. It serves as a reminder that, in the face of overwhelming adversity, the human spirit has the power to triumph over even the darkest forces of tyranny and hatred. Although the scars of slavery may never fully heal, the legacy of those who fought against it shines as a beacon of hope for future generations, inspiring us to continue the struggle for freedom and equality for all.
