Essay on Pollution

Introduction.

Pollution has become a very common yet serious issue in today’s world. It has been there in different forms since a long time even before human evolution such as volcanic eruptions, wildfire which lead to various photochemical reactions in the atmosphere. The current concern is that it is rising day by day due to various resources of pollutants. And, one of the main pollutants are humans and man-made machines. It is right to say that pollution is damaging the mother earth severely and we, humans, should play our part to prevent it from happening.

What is Pollution?

Pollution sepsis is the presence of contaminants in the natural environment that causes harm and damage and therefore leads to adverse changes.

Kinds of Pollution

There are mainly three kinds of pollution - 1) Air Pollution, 2) Water Pollution, and 3) Soil Pollution.

Air Pollution

Air Pollution occurs due to the presence of harmful gases and substances in the air. It is due to vehicle emission, dust and dirt, poisonous gasses from the factories etc. To reduce air pollution, we should use carpooling or public transport rather than using our private mode of transportation whose harmful gas emission only adds to the problem, we should also actively avoid burning trash or other materials etc.

Water Pollution

Water Pollution happens when toxic substances get mixed in various water bodies such as lakes, oceans, rivers etc. Here toxic substances refer to the Chemical fertilizer, Industrial waste, Sewage and wastewater, Mining activities, Marine dumping etc.

Soil Pollution

Soil pollution depicts the contamination of soil due to the presence of toxic substances due to Excessive use of fertilisers and pesticides, deforestation, industrial waste etc . To maintain the soil’s fertility, the government must limit the usage of fertilizers and plant more trees.

There are a few other pollutants causing pollution apart from the aforementioned ones, such as Radioactive pollution. This is one of the rarer types of pollution. It occurs due to the presence of radioactive substances such as the presence of nuclear waste in air, solids, liquids or any other place.

Effects of Pollution on Human Health

Pollution is increasingly having a major effect on the health of human lives. People are gettin g affected by different types of deadly diseases due to the various pollution in air, water and soil. Here are the different diseases humans face due to different pollution.

Due to Air Pollution

Air is an essential part of human life. Humans cannot live without breathing air. But, air pollution causes major damage to human lives. Here are some of the major diseases caused due to air pollution.

Lung cancer

Major coronary heart disease

Respiratory problems

Due to Water Pollution

Water is another source of life. Any living being cannot survive without drinking water.

Essay on Air Pollution in 500 Words

Below we have provided Air Pollution Essay in English, suitable for class 3, 4, 5, 6, 7, 8, 9 and 10 school students. This essay is drafted in easy and simple language.

Air Pollution is an environmental issue that poses a huge threat to billions of organisms surviving on our planet. It has been increasing at an alarming rate with an increase in the concentration of pollutants. The contamination of air by these hazardous pollutants has disrupted the natural balance in our environment. The quality of life has reduced.

Causes of Air Pollution

Two primary phenomena cause air pollution. One of them is the natural phenomenon that comprises volcanic eruptions, wildfires, radioactive elements, and volatile organic compounds. The other most crucial cause is human activity. With the increase in the number of industries, the contamination in the air automatically increases. Fuels and chemicals utilized in factories, mills, and industries release harmful chemicals to the atmosphere. These are organic compounds, gases, particulate matter, ash, and other volatile substances.

Chlorofluorocarbons, also known as CFCs, are another potent reason for air pollution. These chemicals get released from leaky refrigerants, spray tins, burning plastics and various other sources. They deplete the ozone layer and allow harmful UV rays to enter our atmosphere. This, in turn, causes serious illnesses. It is also responsible for smog in urban cities. Smog impairs visibility and can lead to accidents.

Carbon dioxide solely accounts for almost 57 percent of the air pollution. Greenhouse gases and Carbon dioxide together contribute to global warming . They also cause acid rains which are harmful to plants and man-made objects like ancient monuments.

Effects of Air Pollution

With the air quality deteriorating, our future is at stake. Increasing pollution can cause serious health hazards like cancer and cardiovascular issues. Children suffer from bronchitis and pneumonia. Irritation of the nose and throat, asthma attacks, pulmonary diseases are all outcomes of air pollution. Another significant effect of pollution is extreme climate change. Disrupting food chains, extinction of species, depleting the ozone layer are some of the grave issues we face today.

Control of Air Pollution

The Air Pollution Act forbids power sectors and high-scale industries from releasing particulate matter beyond a certain level. Chimneys, Electrostatic precipitators, and filters must be implanted to lessen the damage caused by the emissions.

People must be made aware of the grave conditions of air pollution. The government has taken a huge step to sensitize people regarding the consequences of pollution. We must do our part as well. Using the means of public transport will ensure less number of vehicles. Lesser vehicles mean lesser emission of pollutants.

Planting more and more trees can help solve this crisis. Reforestation in mining areas is also an effective step. Conservation of energy is of prime importance. Renewable energy sources like solar panels, wind turbines, hydroelectric power, and natural gas must be utilized. We must avoid burning dry leaves at our homes and must indulge in the habit of composting.

The implementation of Eco-friendly methods will ensure a cleaner and healthier environment. LPG (Liquefied Petroleum Gas), CNG (Compressed Natural Gas), and Biogas are some Eco-friendly substitutes of fuels. Together, we must strive to bring a change. Our efforts matter because they will bring in much-needed change. After all, everyone wants to live on a healthy planet.

7 Role in Controlling Air Pollution

The presence of unusually high concentrations of harmful or poisonous substances in the environment (air, water, etc.) is called pollution . Pollution contaminates the air and water with poisonous substances and makes them impure to such an extent that they become harmful to the human beings, other animals, plants as well as to the non-living things.

An unwanted and harmful substance that contaminates the environment (such as air and water) is called a pollutant.

The two main gases present in air are nitrogen and oxygen. Nitrogen makes up about 78% of air whereas oxygen makes up about 21% of air by volume. Air also contains small amounts of carbon dioxide, argon and water vapour.

In addition to the normal constituents, the polluted air may also contain harmful substances such as carbon monoxide, sulphur dioxide, nitrogen oxides, smoke and dust, etc. Many respiratory problems are caused by breathing in polluted air.

Fresh water (usable water) is present in rivers, lakes and ponds. Some fresh water is also present under the ground. Due to increasing water pollution, water-borne diseases are also increasing day by day.

The contamination of air with harmful gases (like sulphur dioxide nitrogen oxides, carbon monoxide), smoke and dust, etc. is called air pollution .

The substance whose presence in air makes it impure or contaminated is called an air pollutant.

A substance becomes an air pollutant when it is present in air in such concentration which is high enough to have a harmful effect on the living or non-living things.

The major pollutants which cause air pollution are : Sulphur dioxide, Nitrogen monoxide, excess of Carbon dioxide, Chlorofluorocarbons, and Suspended particulate matter (such as Dust, Smoke and Fly ash)

Sources of Air Pollution

Most of the air pollution is caused by the burning of fuels such as wood, cow-dung cakes, coal ,kerosene, petrol and diesel in homes, motor vehicles (automobiles), factories and thermal power plants.

The various sources of air pollution are:

(1) Smoke emitted from homes by the burning of fuels like wood, cow-dung cakes, kerosene and coal.

(2) Exhaust gases emitted by motor vehicles (automobiles) due to burning of petrol and diesel.Motor vehicles are the major cause of air pollution in big cities.

(3) Smoke emitted by factories and thermal power plants due to burning of coal.

(4) Oil refineries and industries engaged in the production of metals and manufacture of chemicals.

(5) Stone crushers, cement factories, asbestos factories and lead processing units cause air pollution.

(6) Use of chlorofluorocarbons in refrigeration, air conditioning and aerosol sprays.

(7) Smoking causes air pollution

(8) Forest fires and volcanic eruptions are the two natural sources of air pollution which put smoke and dust into the air.

Harmful Effects of Air Pollution

Sulphur dioxide.

(1) Sulphur dioxide is produced by the burning of coal in factories and thermal power plants.

(2) Sulphur dioxide is also produced by the burning of petrol and diesel in motor vehicles.

(3) Oil refineries also emit sulphur dioxide gas into air.

(1) Sulphur dioxide gas in the air causes respiratory problems.

(2) If may even cause permanent lung damage.

(3) Sulphur dioxide gas in polluted air produces acid rain. This acid rain damages trees, plants, soil, aquatic animals (like fish) statues, buildings and historical monuments.

(4) Sulphur dioxide also contributes to the formation of a deadly air pollutant called smog.

Nitrogen Oxides

(1) Nitrogen oxides are produced by the burning of fuels like petrol and diesel in motor vehicles.

(2) They are also produced by the burning of coal in factories and thermal power plants.

The high temperature produced by the burning of fuels like petrol, diesel and coal makes some of the nitrogen and oxygen of air to combine to form nitrogen oxides.

(3) Oil refineries also produce and emit nitrogen oxides into the air.

(1) Nitrogen oxides attack breathing system and lead to lung congestion.

(2) They also attack skin.

(3) Nitrogen oxides present in polluted air produce acid rain.

(4) Nitrogen oxides also contribute to the formation of smog.

Smog is a deadly air pollutant which is formed by the combination of smoke and fog( The minute water particles suspended in air near the surface of earth during cold weather in winter is called fog.)

Smoke contains tiny carbon particles, and harmful gases such as nitrogen oxides and sulphur dioxide. The carbon particles, nitrogen oxides and sulphur dioxide of smoke combine with the condensed water vapour called fog to form smog.

Smog causes cough and aggravates (makes worse) asthma and other lung diseases, especially in children.

Carbon Monoxide

(1) Carbon monoxide is produced by the incomplete combustion of fuels like wood, coal, kerosene, petrol and diesel in homes, factories and motor vehicles.

(2) The exhaust gases of motor vehicles (cars, buses and trucks, etc.) contain carbon monoxide which they emit into air.

(3) Cigarette smoke also contains carbon monoxide.

Carbon monoxide is a very poisonous gas.When inhaled carbon monoxide combines with the haemoglobin of our blood and reduces the oxygen-carrying capacity of blood.Due to this, blood is not able to carry sufficient oxygen to our body parts. This lack of oxygen cause respiratory problems (breathing problems). It causes suffocation. If too much carbon monoxide is inhaled, it may even cause death.

Carbon Dioxide

Carbon dioxide is produced in excessive amounts by the burning of large quantities of fuels such as wood, coal, kerosene, petrol, diesel, LPG, and CNG in homes, factories and motor vehicles.

Excess of carbon dioxide in air is considered a pollutant (because it produces undesirable changes in the environment). Carbon dioxide is the main greenhouse gas which traps sun’s heat in the earth’s atmosphere by producing greenhouse effect which leads to global warming.

Chlorofluorocarbons (CFCs)

Chlorofluorocarbons are the chemical compounds made of chlorine, fluorine and carbon elements. Chlorofluorocarbons are used in refrigerators, air conditioning and aerosol sprays.

Chlorofluorocarbons are industrially useful gases but they also behave as air pollutants because of their damaging effect on ozone layer.

Chlorofluorocarbons are depleting the useful ozone layer of the upper atmosphere. Chlorofluorocarbons released into the air go up and ultimately reach high into the atmosphere where the protective ozone layer exists. They react with the ozone gas of ozone layer and destroy it gradually. Ozone layer prevents the harmful ultraviolet radiations of the sun from reaching the earth. The destruction of ozone layer by CFCs will allow the extremely harmful ultraviolet radiations of the sun to reach the earth. These ultraviolet radiations can cause skin cancer, cataract, and destruction of plants, including crops. A big hole has already been made by the destruction of ozone gas in the ozone layer over the South Pole of the earth. It is called “ ozone hole “.

Suspended particulate matter (SPM)

The finely divided solid or liquid particles suspended in air are called suspended particulate matter.

Some of the examples of suspended particulate matter are : Dust, Smoke and Fly ash.

(a) Dust consists of tiny particles of earth: Dust is produced by blowing wind, heavy traffic on roads, stone crushers and construction activities.

(1) Dust in air spoils our clothes and reduces visibility.

(2) Dust produces allergic reactions in human body and aggravates diseases like bronchitis.

(3) Dust covers the leaves of plants and trees and prevents photosynthesis.

(b) Smoke is mainly tiny particles of carbon in air. Smoke is produced by the burning of fuels like wood, cow-dung, cakes, kerosene, petrol, and diesel in homes, factories, thermal power plants and motor vehicles.

Smoke present in air spoils our clothes and blackens the buildings. Smoke attacks our lungs and causes respiratory diseases.

(c) The minute ash particles formed by the burning of coal and carried into air by the gases produced during burning, is called fly ash.

Fly ash particles present in air cause irritation to the eyes, skin, nose, throat and respiratory tract. Continued breathing in air containing fly ash causes diseases like bronchitis and lung cancer.

The two extremely harmful effects of air pollution on the environment are acid rain and greenhouse effect (or global warming).

Controlling Air Pollution

Some of the ways of controlling air pollution are:

(1) The air pollution can be controlled by using smokeless fuels like LPG, PNG (Piped Natural Gas and Bio-gas for cooking food (instead of wood, cow-dung cakes, or coal). Solar cookers can also be used for cooking food. Solar water heaters should be installed for obtaining hot water.

(2) The air pollution from motor vehicles can be reduced by using CNG (Compressed Natural Gas) as fuel in place of petrol and diesel. CNG is a very clean fuel which does not pollute air

(3) The air pollution from factories, thermal power plants, oil refineries and chemical industries can be controlled by washing down their smoke and waste gases with jets of water. When the smoke and waste gases are sprayed by jets of water before they reach chimney, then soot present in smoke is washed away and most of the poisonous gases like sulphur dioxide and nitrogen oxides get dissolved in water.

(4) The air pollution can be controlled by using non-polluting sources of energy like solar energy, wind energy and hydroenergy for generating electricity. This will reduce the use of fossil fuel like coal which is used for generating electricity at thermal power plants and causes air pollution.

Role in Controlling Air Pollution

Some of the steps which can be taken as individuals (or as a group of individuals) to control air pollution and improve the quality of air around us are as follows :

(1) We should not burn dry leaves, papers and garbage in the open : Leaves should be converted into compost by burying in a pit ; used papers should be sent to paper mills for recycling; and garbage should be deposited in the garbage dumps established by the Municipal Corporation of the city.

(2) We should save electricity: If all of us start saving electricity by avoiding its wastage in homes, schools, shops, offices and factories, the demand for electricity will decrease. This will lead to the burning of less coal to generate electricity. And burning of less coal will reduce air pollution.

(3) We should grow more trees and also take care of the existing trees in our neighbourhood. Trees reduce pollution by absorbing excess carbon dioxide from the air.

(4) We should join “Say No to Crackers” campaign organised by children of many schools during Diwali days to reduce the level of air pollution during the festival season.

(5) We should use bicycle for covering short distances. This will save precious fuel like petrol (which we use in cars, scooters and motorcycles) and also reduce air pollution.

(6) We should use the school bus or public transport bus for going to school.

Title: Air Pollution – A Looming Environmental Crisis

Introduction :

Air pollution has emerged as a major environmental concern globally, posing significant threats to human health and the planet. It is the presence of harmful substances in the air, resulting from human activities and natural processes. This essay delves into the causes, impacts, and solutions to air pollution. By exploring the sources of pollution, health consequences, and mitigation strategies, we can better understand the severity of the issue and work towards a cleaner and healthier environment.

Causes of Air Pollution

Air pollution is primarily caused by human activities such as industrial emissions, vehicle exhaust, burning of fossil fuels, and agricultural practices. Industrial processes release large amounts of pollutants into the air, including particulate matter, nitrogen oxides, sulfur dioxide, and volatile organic compounds. Vehicle emissions, particularly from automobiles and trucks, contribute significantly to air pollution, releasing pollutants like carbon monoxide and nitrogen oxides. The burning of fossil fuels, such as coal and oil, for electricity generation and heating purposes, also releases pollutants into the atmosphere. Additionally, agricultural practices involving the use of fertilizers, pesticides, and livestock contribute to air pollution through the release of ammonia and methane.

Health Impacts of Air Pollution

Air pollution has severe health consequences, particularly for vulnerable populations such as children, the elderly, and individuals with pre-existing respiratory and cardiovascular conditions. Exposure to pollutants can lead to respiratory problems, including asthma, bronchitis, and chronic obstructive pulmonary disease (COPD). Fine particulate matter, known as PM2.5, can penetrate deep into the lungs and enter the bloodstream, causing cardiovascular diseases and increasing the risk of heart attacks and strokes. Long-term exposure to air pollution has been linked to lung cancer, respiratory infections, and reduced lung function. Moreover, air pollution exacerbates allergies, triggers asthma attacks, and impairs lung development in children.

Environmental Impacts

Air pollution not only affects human health but also poses significant risks to the environment. It contributes to climate change by releasing greenhouse gases, such as carbon dioxide and methane, into the atmosphere. These gases trap heat, leading to global warming and the disruption of ecosystems. Acid rain, a consequence of air pollution, harms forests, lakes, and aquatic life. Pollutants released into the atmosphere can also lead to the formation of smog and haze, reducing visibility and impacting tourism, outdoor activities, and overall quality of life. Additionally, air pollution has adverse effects on agriculture, damaging crops and reducing yields.

Mitigation Strategies

Addressing air pollution requires a comprehensive approach that involves governments, industries, communities, and individuals. Governments play a crucial role in setting air quality standards, implementing regulations, and monitoring compliance. They must promote cleaner technologies and renewable energy sources, incentivize industries to reduce emissions and enforce penalties for non-compliance. Additionally, governments should invest in public transportation systems, promote the use of electric vehicles, and adopt sustainable urban planning to reduce vehicle emissions.

Industries can contribute to pollution control by adopting cleaner production processes, investing in sustainable technologies, and implementing emission reduction strategies. Encouraging the use of alternative fuels, such as biofuels, and implementing energy-efficient practices can also mitigate air pollution.

Communities and individuals can play an active role in reducing air pollution by adopting sustainable practices. This includes reducing energy consumption, conserving resources, practicing responsible waste management, and using public transportation or carpooling. Raising awareness about the impacts of air pollution and promoting sustainable lifestyle choices can foster a collective effort in combating pollution.

Conclusion:

Air pollution remains a critical environmental issue that demands urgent action. By understanding the causes, impacts, and solutions to air pollution, we can work towards cleaner air and a healthier planet. Collaboration among governments, industries, communities, and individuals is necessary to implement effective mitigation strategies. Through the adoption of cleaner technologies, the promotion of renewable energy sources, and the practice of sustainable living, we can protect human health, preserve the environment, and ensure a sustainable future for generations to come.

The air we breathe, the water we drink, the security of creatures we drink, the security of creatures we share with, and fertility of land on which we grow our food are all deteriorating resulting in the increase of health hazards and lowering standard of health of the nation as a whole, In this seemingly desperate situation how to let our optimum survive is a burning question of the day.

A study conducted by the World Bank in 1995 revealed that 40,000 Indians die prematurely due to polluted air in cities. Yet another study made by the Environment protection Agency shows that every nearly 40,000 children in India are affected by respiratory diseases caused by the growth of carbon dioxide in the atmosphere. Air pollutants are continually poisoning our bones and the most susceptible to pollution are children below five years and elderly persons above 50 years. In general, those who have hyper-responsiveness to the presence of pollutants are bit harder than others. Air pollutants increase the risk of lung disease in asthma patients. Women with previous lead exposures may have elevated blood level during period of high bone turnover as observed during pregnancy, location or hyperthyroidism. Their unborn fetuses may be exposed to this danger as also the new born though breast milk. Children have relatively narrower air passages which are more easily obstructed. They need more oxygen whereas they inhale larger volumes of polluted air. Children are three times more at risk & exposure to pollutants floating in the sky than adults. In Delhi every tenth school going kid is suffering from asthma caused by air pollution. Traffic police men, automobile mechanics, drivers, cyclists, rikshaw-walas, road side vendors and hawkers all inhale more pollutants than others due to the nature of their work.

Vehicular discharged is the most important of pollutants which is wrecking the health of urban populace. Human body can tolerate up to 0.25 milligram of lead in blood. But a resident of cities like Delhi, Mumbai, and Chennai through vehicles.

Air pollution is not visible to the naked eye nor can it be handled or removed by individual efforts. Polluted water can be purified before drinking, polluted food can be done away with, noise pollution can also be controlled by individual efforts but air pollution can be controlled only by the ruling authority. In Singapore owning and running a car has been made so expensive that fewer people dare possess a car. There are many zones in European countries where vehicles are prohibited from plying; High registration fees and restriction on the movement of vehicles can go a long way in saving us from toxns. Keeping half the existing vehicles off the road for two days in a week, improving the quality of fuel and traffic management may also be helpful.

These are all prohibitive measures, which can be enforced only by the Government. Certain protective measures should also be adopted for effective control of this menace. Tree plantation can go a long way to balance the ratio of carbon dioxide in atmosphere. During photosynthesis plants absorb carbon dioxide and release oxygen. Hence plantation of trees wherever possible and ban on cutting of green trees will help in maintaining proper balance in atmosphere. Agricultural land must also be kept under one crop or the other. This will not only protect from air pollution but will also put a check to soil erosion which is an important factor responsible for the loss of fertility of soil.

Water pollution can be checked by keeping our rivers, canals and lakes clean. Industrial wasted must also be disposed off in such a way that it does not contribute to pollution of air and water. At no cost it should be allowed to find its way to the rivers. Use of insecticides in agricultural crops, fruit trees, garden and vegetable crops as also in houses should be judiciously planned.

Noise pollution can be easily and effectively controlled by our individual and social efforts. Proper tuning of musical sets, radios, loudspeakers, T.V. sets and vehicle horns etc. should be practiced.

These should be sustained efforts to find alternatives like solar powered vehicles and appliances to reduce our dependence upon oil engines to run vehicles and generator sets. Only when the problem is tackled on war footing can we control this problem of pollution.

Brief Notes on Class 8 Pollution of Air and Water

Air is a very important element in the atmosphere which makes this Earth livable for us. It consists of a mixture of gases which by volume are – about 78% of nitrogen, about 21% oxygen and carbon dioxide, argon, methane, ozone, and water vapors in very small quantities.

Air Pollution

Contamination of air by unwanted substances which has a harmful effect on both the living and the non-living is referred to as air pollution. A thick fog-like layer in the atmosphere especially during winter is smog which is made up of smoke and fog. Smoke contains oxides of nitrogen which combine with other air pollutants and fog to form smog. The smog causes breathing difficulties such as asthma, cough, and wheezing in children.

Air Pollutants

The substances which contaminate the air are called air pollutants. Sometimes, such substances may come from natural sources like smoke and dust arising from forest fires or volcanic eruptions, or certain human activities.

The sources of air pollutants are factories, power plants, automobile exhausts, and the burning of firewood and dung cakes.

The Vehicles produce high levels of pollutants like carbon monoxide, carbon dioxide, nitrogen oxides, and smoke.
Carbon monoxide is also produced from the incomplete burning of fuels such as petrol and diesel. It is a poisonous gas because it reduces the oxygen-carrying capacity of the blood.
Many industries like petroleum refineries are major sources of gaseous pollutants like sulphur dioxide and nitrogen dioxide. Sulphur Dioxide is produced by the combustion of fuels like coal in power plants. It can cause respiratory problems and permanent lung damage.
Other kinds of pollutants are chlorofluorocarbons (CFCs) which are used in refrigerators, air conditioners, and aerosol sprays. CFCs damage the ozone layer of the atmosphere which is very harmful. Less harmful chemicals are being used in place of CFCs these days.

Not only living organisms but non-living things like buildings, monuments, and statues also get affected by air pollution. One such example of a famous monument being affected by air pollution is the Taj Mahal which is one of the 7 wonders of the world.

The industries located around Agra like rubber processing, automobile, chemicals, and oil refinery have been responsible for producing pollutants like sulphur dioxide and nitrogen dioxide. These gases react with the water vapors present in the atmosphere to form sulphuric and nitric acid. This acid then mixes with rain making it acidic and it is called acid rain .

This Acid rain corrodes the marble of the monument through a phenomenon called “ Marble cancer ”. Suspended particulate matter such as the soot particles emitted by oil refineries and other factories have contributed to the yellowing of the marble of the Taj Mahal. The Supreme Court has therefore taken steps to save the Taj by ordering industries to switch to cleaner fuels like CNG (Compressed Natural Gas) and LPG (Liquefied Petroleum Gas) and automobiles to switch over to unleaded petrol in the Taj zone.

Green House Effect

The trapping of radiation by the earth’s atmosphere is similar to how the greenhouse traps heat to keep the plants inside the greenhouse warm. That is why it is also called the greenhouse effect. Without this process, life is not possible on Earth. But the excess of this phenomenon threatens and endangers life on Earth.

Greenhouse Gases

Gases like CO2, methane, nitrous oxide, and water vapors also contribute to the greenhouse effect hence they are called greenhouse gases

Global Warming

The gradual increase in the average temperature of the Earth’s atmosphere is called global warming. Global warming can cause sea levels to rise and affect rainfall patterns, agriculture, forests, plants, and animals.

Deforestation leads to an increase in the amount of CO2 by reducing the number of trees that consume CO2. Human activities contribute to the accumulation of CO2 in the atmosphere adding to the greenhouse effect and thus eventually Global Warming.

What can be done to reduce air pollution?

A decision was taken by the government to switch to fuels like CNG unleaded petrol in vehicles which has resulted in cleaner air for the country.
“Say no to crackers” campaign was organized by children from many schools and it made a big difference to the air pollution levels around Diwali.
Switching over to alternative fuels like solar energy, hydropower, and wind energy instead of fossil fuels for our energy requirements could help a lot.
Small contributions on our part like Aforestation can help a lot. Van Mahotsav is organized every year in July when lots of trees are planted. So we can help plant trees and nurture the ones already present in the neighborhood.

Water Pollution

Water is another one of the most important elements which are required for the sustenance of life on Earth. But clean water is what gives us life whereas contaminated water can give us diseases.

Potable Water

The water suitable for drinking is called potable water.

The contamination of water by unwanted and harmful substances is called Water pollution.

Water Pollutants

The substances that pollute water like sewage, toxic chemicals, silt, etc. are called water pollutants.

One big example of water pollution in our country is pollution of Ganga. A study by the (WWF) World Wide Fund for Nature found that river Ganga is one of the 10 most endangered rivers in the world and the pollution levels in it have been rising steadily for many years. The towns and cities through which the river flows throw large quantities of garbage, untreated sewage and many other harmful things directly into the river. In fact the river has been declared ‘dead’ at many places where the pollution levels are so high that aquatic life could not survive.

The Ganga Action Plan was launched in 1985 to reduce the pollution levels in the river. The increasing population and industrialization have already damaged this beautiful river beyond repair and therefore the Government of India launched another initiative known as (NMCG) National Mission for Clean Ganga in 2016.

Causes of Water Pollution

Many industries like oil refineries, paper factories, textile and sugar mills, and chemical factories discharge harmful chemicals into rivers and streams, causing the pollution of water. This is called chemical contamination of water. The chemicals released into the water include arsenic, lead, and fluorides which lead to toxicity in plants and animals. There are regulations to prevent this and industries are supposed to treat the waste produced before discharging it into the water but the rules are not followed very often. The soil is also affected by the impure water causing changes in acidity, growth of worms, etc in the soil.
All the chemicals in weedicides and pesticides dissolve in water and are washed into water bodies from the fields and even seep into the ground and pollute groundwater. These chemicals in the water bodies act as nutrients for algae to flourish which serve as nutrients for algae to flourish. A lot of oxygen is used up by these unwanted processes which result in a decrease in the oxygen level and can kill aquatic organisms.
Untreated sewage with food wastes, detergents, micro-organisms, etc. when thrown directly into the water bodies also causes water pollution. Water contaminated with sewage may contain bacteria, viruses, fungi, and parasites which can cause diseases like cholera, typhoid, and jaundice.
Hot water can also become a pollutant. When released into the rivers power plants and industries it can raise the temperature of the water body which adversely affects the animals and plants living in it because they are used to a certain temperature of the water. Sudden fluctuation in the temperature affects the flora and fauna negatively and can even kill them.

How to Make Water Safe

Filtering- A popular household filter is a candle-type filter.
Boiling- Many households use boiling for obtaining safe drinking water. Boiling kills the germs present in the water and makes it safe for drinking.
Chlorination– It is a commonly used chemical method for purifying water by adding chlorine tablets or bleaching powder to the water. But more chlorine tablets than specified should not be used because they are harmful.
Water treatment plants– Laws should be strictly implemented so that polluted water isn’t disposed of directly into rivers and lakes. Water treatment plants should be installed in all industrial areas.
At an individual level, one should consciously save water and not waste it. Reduce, reusing and recycling should be used diligently as a method. Reusing water used for washing and for other household tasks, water used for washing vegetables can be used to water plants in the garden, while brushing your teeth or washing utensils the taps should be turned off. Leaving the tap running can waste several liters of water. Using simple methods in our everyday routine can help in saving water.

Clean air consists of a mixture of gases which by volume are – about 78% of nitrogen, about 21% oxygen, and carbon dioxide, argon, methane, ozone, and water vapors in very small quantities. Whereas polluted air contains unwanted substances called air pollutants which have a harmful effect on both the living and the non-living.

Contamination of air by unwanted substances which has a harmful effect on both the living and the non-living is referred to as air pollution. The contamination of water by unwanted and harmful substances is called Water pollution.

Water can be contaminated by the things given below – • Many industries like oil refineries, paper factories, textile and sugar mills, and chemical factories discharge harmful chemicals into rivers and streams, causing the pollution of water. This is called chemical contamination of water. The chemicals released into the water include arsenic, lead, and fluorides which lead to toxicity in plants and animals. There are regulations to prevent this and industries are supposed to treat the waste produced before discharging it into the water but the rules are not followed very often.

Water contaminated with sewage may contain bacteria, viruses, fungi, and parasites which can cause diseases like cholera, typhoid, and jaundice. • Hot water can also become a pollutant. When released into the rivers power plants and industries it can raise the temperature of the water body which adversely affects the animals and plants living in it because they are used to a certain temperature of the water. Sudden fluctuation in the temperature affects the flora and fauna negatively and can even kill them.

Essay on Environmental Pollution for Students and Children

500+ words essay on environmental pollution.

Essay on Environmental Pollution – Environment is the surroundings in which we live. But the contamination of our environment by pollutants is environmental pollution. The current stage of the earth that we are seeing is the cause of centuries of exploitation of earth and its resources.

Moreover, the earth cannot restore its balance because of environmental pollution . The human force has created and destroyed life on earth. Human plays a vital role in the degradation of the environment.

Effect of pollution on the health

The environmental pollution, directly and indirectly, affects the lives of humans and other species. These living beings co-existed on the earth with human from centuries.

Effect on Air

Carbon and dust particles string up with the air in the form of smog, damaging respiratory system , haze, and smoke. These are caused by the emission of industrial and manufacturing units by burning of fossil fuels, vehicle combustion of carbon fumes.

Moreover, these factors affect the immune system of birds which become a carrier of viruses and infections.

Besides, it also affects the body system and body organs.

Effects on Land, Soil, and Food

Human’s organic and chemical both waste harm the land and soil with its decomposition. Also, it introduces some chemical in the soil and water. Land and soil pollution mainly caused by the use of pesticides, fertilizers , soil erosion, and crop residues.

Effect on Water

Water gets contaminated easily with any pollutant whether it is human waste or chemical discharge from factories. Also, we use this water for irrigation of crops and drinking. But, because of infection they become contaminated too. Besides, an animal dies because they drink this same contaminated water.

Moreover, around 80% of pollutants of land such as chemical, industrial and agricultural waste end up in the water bodies.

Besides, these water bodies ultimately connect to the sea which means it indirectly pollutes the biodiversity of the sea.

Effect on Food

Because of contaminated soil and water, the crop or agricultural produce also get toxic. Furthermore, this contaminated food effect our health and organs. From the beginning of their life, these crops are laced with chemical components that reach a mass level until the time of harvest.

Effect on Climate

Climate change is also a cause of environmental pollution. Also, it affects the physical and biological components of the ecosystem.

Moreover, ozone depletion, greenhouse gases, global warming all these climate changes are a cause of environmental pollution.

Furthermore, some unstable climate changes are earthquakes, famine, smog, carbon particles, shallow rain or snow, thunderstorms, volcanic eruption, and avalanches are all because of climate change that happens all because of environmental pollution.

In conclusion, man has exploited the wealth of nature at the cost of his and environments health. Also, the effect that is now emerging rapidly is all because of the activities of humans for hundreds or thousands of years.

Above all, if we wish to survive and continue our life on earth then we have to take measures. These measures will help is securing our as well as our next generation future.

The release of such air pollutants in heavy concentrations such as smog, particulates, solid materials, etc., are getting settled over the city, causing air pollution and health hazards. Many dirty wastes are produced by people daily, especially in the big cities polluting the whole atmospheric air to a great extent.

The release of gaseous pollutants from burning fuel of motor vehicles, industrial processes, burning of garbage, etc., are contributing to the air pollution. Some natural pollutants like pollen, dust, soil particles, natural gases, etc., are also sources of air pollution.

Air Pollution Essay 150 words

is the mixing of harmful substances into the atmosphere fresh air causing huge levels of damage, human health disorders, reducing the quality of life, etc. Air pollution is increasing daily because of the increasing number of industries. Such polluted air never remains in one place but spread to the whole environment and affects people’s lives all through the world. Death rates of human beings have increased because of an increased variety of diseases. The polluted air we breathe every moment causes lung disorders and even lung cancer, thus affecting the health of other body organs.

Air pollution continuously damages the whole ecological system and affects the lives of plants and animals. It has reached a critical stage and affected the whole atmosphere by allowing more harmful radiations from the sun to the earth. Again polluted air acts as a better insulator that prevents heat from escaping back into space.

Air Pollution Essay 200 words

Air pollution is one of the main environmental issues nowadays. There are many reasons behind regularly increasing this air pollution. Most air pollution is caused by automobiles, transport means, industrialization, growing cities, etc. The release of several harmful gases or dangerous elements from such sources is causing whole atmospheric air pollution. The ozone layer is also getting affected too much by air pollution, which causes serious disturbances to the environment. The increasing need of the ever-growing human population is the main cause of pollution. Daily human being activities causing dangerous chemicals to release, making the atmosphere dirtier than ever and forcing climate change negatively.

The industrialization process releases harmful gases, particles, paint, and batteries containing lead; cigarettes release carbon monoxide, and transport means release CO2 and other toxic substances into the atmosphere. All the pollutants are in contact with the atmosphere, destroying the ozone layer and calling harmful sun rays to the earth. In order to reduce the level of air pollution, we should bring some huge changes to our habits on a daily basis. We should not cut trees, use public transportation, avoid spray cans, and do so many activities to reduce the effects of air pollution.

Air Pollution Essay 250 words

Air pollution is the mixing of foreign substances into the whole atmospheric air. Harmful and toxic gases emitted by industries and motor vehicles cause huge damage to living organisms, whether plants, animals, or human beings. Some of the natural and various human resources are causing air pollution. However, most air pollution sources stem from human activities like burning fossil fuels, coal, and oil and releasing harmful gases and substances from factories and motor vehicles. Harmful chemical compounds like carbon dioxide, nitrogen oxides, carbon monoxide, sulfur dioxide, solid particles, etc., are getting mixed into the fresh air. The level of air pollution has increased greatly because of the 690% increase in damaging pollutants because of the expanded need for motor vehicles in the last century.

Another source of air pollution is the decomposition of garbage in landfills and the disposal of solid wastes emitting methane gas (dangerous to health). The rapid growth of population, industrialization, and increased use of automobiles, airplanes, etc., have made this issue a serious environmental problem. The air we breathe every moment is full of pollutants going to our lungs and whole body through blood, causing uncountable health problems. Therefore polluted air is causing damage to plants, animals, and human beings in many direct and indirect ways. If the environmental protection policies are not followed seriously and strictly, the increasing level of air pollution may increase to one million tons annually in recent decades.

Air Pollution Essay 300 words

When the fresh air gets polluted by means of dust, toxic gases, smoke, motor vehicles, mills, factories, etc. called air pollution. As we all know that fresh air is the most important element of a healthy life, we need to think that what happens if the whole atmospheric air gets dirty. First, air pollution is a matter of great regret for the whole human fraternity. Some of the big reasons for air pollution are poisonous fertilizers, insecticides, and pesticides in the agricultural sectors by innocent farmers to increase crop production. Released chemicals and hazardous gases (ammonia) from fertilizers are getting mixed into the fresh air and causing air pollution.

The burning of fossil fuels such as coal and petroleum and other factory combustibles are the major causes of air pollution. A variety of smoke emissions from the automobiles, such as cars, buses, motorcycles, trucks, jeeps, trains, airplanes, etc., are also causing air pollution. An increasing number of industries are causing the release of toxic industrial smokes and harmful gases (like carbon monoxide, organic compounds, hydrocarbons, chemicals, etc.) from the factories and mills to the environment. Some indoor activities of the people, like innocent use of cleaning products, washing powders, paints, etc., emit various toxic chemicals into the air.

The ever-increasing level of air pollution also enhances its harmful effects on the health of living beings. Air pollution is causing global warming to increase because of increasing atmospheric temperature due to the increasing level of greenhouse gases. Such greenhouse gases again cause greenhouse effect and force sea levels to increase, glaciers to melt, weather to change, climate to change, etc. Increasing air pollution is causing many lethal diseases (cancer, heart attack, asthma, bronchitis, kidney diseases, etc.) and death. Various important animal and plant species have been destroyed completely from this planet. The increasing level of harmful gases in the environment is causing the occurrence of acid rain and depleting the ozone layer.

Air Pollution Essay 400 words

The increasing concentration of harmful and toxic materials in the fresh air of the atmosphere is causing air pollution. Various foreign particles, toxic gases, and other pollutants released from various human activities are affecting the fresh air, which has an adverse effect on living beings like humans, animals, and plants. Air pollution levels depend on the type and amount of pollutants released from various sources. Topographical and meteorological conditions are increasing the spread and concentration of pollutants. Therefore variety of raw materials used in the manufacturing process in industries is increasing the type and quantum of emissions of harmful gases. Increasing population density is demanding the need for more industrialization, which ultimately causes air pollution.

Air Pollutants like harmful liquid droplets, solids particulates, and toxic gases (oxides of carbon, halogenated and non-halogenated hydrocarbons, nitrogen and sulfur gases, suspended inorganic particulate matters, inorganic and organic acids, bacteria, viruses, insecticides, etc.) which are generally not the constituents of fresh air are very hazardous to the plant and animal life. There are two types of air pollution sources which are natural sources and man-made sources. Some natural sources of air pollution are volcanic eruptions, volcanoes (ashes, carbon dioxide, smokes, dust, and other gases), deflation of sands, dust, salts spray from seas and ocean, soil particles, storms, forest fires, cosmic particles, rays, the bombardment of asteroid materials, comets, pollen grains, fungal spores, viruses, bacteria, etc.

However Man-made sources of air pollution are industries, agriculture, power plants, automobiles, domestic sources, etc. Some of the air pollutants from man-made sources are smoke, dust, fumes, particulate matter, gases from the kitchen, domestic heating, emissions from different vehicles, use of insecticides, pesticides, herbicides, and the heat created from power plants, smokes, fly ash, etc. Because of the increasing number of air pollutants, it has divided into two types: primary and secondary pollutants. Primary pollutants directly affect the fresh air and emitted from smoke, ash, dust, fumes, mist, spray, inorganic gases, carbon dioxide, carbon monoxide, sulphur dioxide, hydrogen sulphide, ammonia, nitric oxide, and radioactive compounds. Secondary pollutants indirectly affect the air by chemical interactions with the primary pollutants and other atmospheric constituents such as sulphur-trioxide, ozone, hydrocarbons, nitrogen dioxide, etc.

The get-together effort of human beings all over the world may help in controlling the level of air pollution. Establishment of industrial estates should away from residential areas, motivate use of tall chimneys instead of small, promote the use of high-temperature incinerators. However use of non-combustive sources of energy, promote the use of non-lead antiknock agents in the gasoline, promote re-plantation and so many positive efforts.

Air pollution essays given above useful to range of students studying in classes 1 to 10, etc. You can select any of them according to your need and requirement. Also you can use in an exam or essay writing competition at any event. Apart from an essay on air pollution, you can get other related essays and related information such as:

Exercise Questions

1. What are the different ways in which water gets contaminated ?

The different ways in which the water gets contaminated are listed below:

i) Industrial waste: The harmful chemical wastes get released by the industries into water sources.

ii) Sewage waste: K itchen, laundry, and toilets release waste materials, and this pollutes water.

iii) Agricultural chemicals: Excessive amounts of pesticides and fertilizers are used by farmers to enhance crop production. Rains and floods carry these harmful chemicals to water bodies, which results in water pollution.

2. At an individual level, how can you help reduce air pollution?

We can take the following steps to reduce air pollution:

i) We should avoid using personal cars and opt for public transport as much as possible.

ii) We should properly dispose of the garbage and not burn it.

iii) For shorter distances, avoid vehicles.

iv) We should control the number of emissions from household chimneys and vehicles.

v) We should replace our vehicle fuel, diesel and petrol with LPG and CNG.

3. Clear, transparent water is always fit for drinking. Comment.

No, we don’t agree with the statement that clear water is always fit for drinking because water might appear clean, but it may contain some disease-causing micro-organisms and several other dissolved impurities. Hence, we advise purifying the water by boiling it or by any purifying system before drinking it.

4. You are a member of the municipal body of your town. Make a list of measures that would help your town to ensure the supply of clean water to all its residents.

The following are the measures taken by us to ensure the supply of clean water to our town residents:

a) We clean the area around the water pipes.

b) The main water source has to be built in a clean surroundings and should be maintained properly.

c) Chemical methods such as chlorination must be used for purifying water.

5. Explain the differences between pure air and polluted air.

The composition of pure air contains 78% nitrogen, 21% oxygen and 0.03% carbon dioxide. Besides these, there are some other gases like methane, argon, ozone and water vapours’. The air is said to be polluted when the composition of air is altered by the addition of harmful substances or gases such as sulphur dioxide, carbon monoxide, nitrogen dioxide and particulate matter.

6. Explain circumstances leading to acid rain. How does acid rain affect us?

Sulphur dioxide and nitrogen dioxide are the type of pollutants which are released into the atmosphere by the burning of fossil fuels like diesel and coal. These pollutants react with the water vapours present in the atmosphere to form nitric acid and sulphuric acid, respectively. By precipitation, these acids come down and form acid rain.

Effects caused by acid rain:

a) It destroys the crops.

b) Harmful for buildings, especially those made of white marble like the Taj Mahal.

7. Which of the following is not a greenhouse gas?

(a) Carbon dioxide

(b) Sulphur dioxide

(d) Nitrogen

The answer is (d) Nitrogen

8. Describe the ‘Green House Effect’ in your own words.

The greenhouse effect is the cause of global warming, i.e., overall increase in the temperature of the Earth. The greenhouse gases cause the greenhouse effect. Examples of greenhouses gases include methane, CO 2 and water vapour. When solar radiation reaches the Earth, some radiation is absorbed by the Earth and then released back into the atmosphere. Greenhouse gases present in the atmosphere trap these radiations and do not allow the heat to leave. This helps our planet in keeping warm and thus helps in human survival. However, an indiscriminate increase in the level of greenhouse gases can lead to an excessive increase in the Earth’s temperature leading to global warming.

9. Prepare a brief speech on global warming. You have to deliver the speech in your class.

The increase in the average temperature of the Earth’s surface is known as global warming. It occurs due to the increased concentration of greenhouse gases in the atmosphere. The greenhouse gases include methane, CO 2 , and water vapour. These gases trap the solar radiation released back by the earth, which results in keeping our planet warm and helps in human survival. However, an increase in these gases can lead to an increase in the earth’s temperature resulting in global warming.

10. Describe the threat to the beauty of the Taj Mahal.

The major threat to the Taj Mahal is acid rain. When the acid rain falls on the Taj, which is completely made of marble, they react with marble to form a powder-like substance which is then washed away by the rain. This phenomenon is known as marble cancer. In addition, the soot particles emitted from the Mathura oil refinery located near Agra are leading to the yellowing of the Taj Mahal marble.

11. Why does the increased level of nutrients in the water affect the survival of aquatic organisms?

An increase in the level of nutrients in the water body leads to an excessive increase in the population of algae in the water body. When these algae die, they serve as food for decomposers. A lot of oxygen is utilized in this process, consequently leading to a decrease in the level of oxygen dissolved in the water body. This, in turn, causes fish and aquatic organisms to die.
