Long Essay on Water in English

Water, the pivotal ingredient in the essence of life, is the most important non-renewable resource, other than oxygen, for life to exist and thrive on our planet. Water which makes up almost one-third of the face of the planet has only 2.75% to 3.1% of fresh after that can actually be used by human beings, animals and plants.

This small percentage of fresh water is used by all living beings for their growth and survival. Plants and trees use it to for photosynthesis to grow. Animals and human beings use water to drink and bathe every day. Hence, judicious use of after should be followed since water is non-renewable and depleting at an ever-increasing rate. At this rate, water will become redundant for future generations, which is to say that life will become non-existent on earth. Experts say that those unimaginable days are not very far from us if we don’t use water with responsibility.

Water that is present in oceans and seas, that is saltwater, is not consumable by human beings and land animals. But this water acts as a lifeline for certain aquatic life.

There are various types of water resources, both potable and non-potable, in the world namely, surface water, rainwater, groundwater, well water, lake water, river water, glaciers, snow etc. All these water bodies form the main source of water on the planet. And to keep these water bodies replenished all the time, a healthy water cycle should be maintained in our ecosystem. Any little disturbance in the water cycle can lead to global warming, floods and droughts.

Usages of water

• Human beings use water for drinking bathing, cooking, washing, watering etc.
• Industries and factories use water for manufacturing purposes
• Animals use water for drinking and bathing
• Plants and trees use water to grow and produce food
• Farmers use water to cultivate the land and fulfil the population hunger
• Power plants and nuclear plants use water to produce energy and power

Why is Water Important for the Human Body?

• More than 70% of our body is made up of water. Without it, the human race will not survive
• Water in our body helps in regulating body temperature
• It keeps our organs and tissue moist and functioning
• It helps in digestion and breaking down of the food we take inside our bodies
• It keeps our skin healthy and nutritious

Scientists and engineers are working on projects and research, from many years, to convert saltwater into freshwater. If they succeed in doing that, then water will not be scarce anymore, but nevertheless, people should learn to use water judiciously, because we never know what nature might throw at us if we play with it. But till then, the only way out to survive is to use water very irresponsibly and strategically.

It is also predicted that the next world war will be fought for water. The symptoms of that are already being seen in the world nowadays, with examples like India and Pakistan fight over the Indus river, Turkey, Syria and Iraq fighting over Tigris-Euphrates river water, Karnataka and Tamil Nadu fighting over Kaveri river in India. These symptoms, if not taken care now itself, will easily lead to world war having catastrophic effects on humankind.

Before all these leads to the extinction of mankind, all the governments of different countries, people, businesses and organisation should come together and formulate proper policies and laws for responsible usage of water in the future.

Short Essay on Water in English

We have provided a 150 to 200 words essay on water which can be used by school students and children for their assignments and projects.

Water, the life-saving universal solvent is the most important element for the existence of living beings on earth.

Water is usually found in three states of matter, namely liquid, solid and gas. All three forms of water are important for the survival of the human race. Water, being a non-renewable resource is depleting at a very faster rate without any source of replenishment. The only way drinking water can be replenished and regenerated is through a healthy water cycle in the atmosphere. And for this water cycle to be maintained well, human beings need to learn to use natural resources like forest, coal and natural gas efficiently without harming the cycle of life.

Since water supports all forms of life, from surface animals and plant to aquatic plant and animals, the water resource belongs to every being on this plant and human beings should not be selfish in their greed for the usage of water.

The unplanned building of damns and man-made reservoirs, and being a thorn in the natural way of life has all affected the actual cycle of water. This has lead to massive drought and floods in various parts of the world.

All human beings should come together and join hands to use water efficiently and not indulge ourselves in the natural cycle of life and let nature thrive on their own.

• Frequently Asked Questions on Water

Water is a vital element of life. It is possible to stay alive for a few days without food, but it is impossible to stay alive without water, even for a single day. To write a paragraph on water, you can refer to the samples provided below for various word limits.

Water is the primary and essential need of every living organism. It is the most precious gift by nature that helps in survival. 70% of our body is filled with water, which is why it is an essential part of our life. Water is needed for various purposes every day. We need water for drinking, washing, cleaning, cooking, etc. Just like there is no life without oxygen, there is no existence without water. It exists in the form of seas, oceans, etc., and also in the form of ice. It is not only an essential element for human beings but also crucial for the survival and existence of plants, animals, birds, etc.

Water is the most important component of life, which is needed by human beings and needed for animals, birds, trees, etc. It exists in three different forms on the earth, i.e., solid, liquid, and gas. Water exists in the form of ice (solid), and water vapour (gaseous) forms. It also exists in the form of liquid in the seas, oceans, rivers, etc., but the composition of water remains the same throughout the earth. It is an important compound that is needed by all living organisms. Plants need water for photosynthesis, and humans need water for various purposes like cooking, bathing, washing, etc. So, like oxygen is an essential component for survival, water is also a crucial component of life.

Even though 3/4th part of the earth is covered by water, the amount of freshwater is low. Since the amount of freshwater is comparatively lower, it is necessary to conserve water by various means. For a healthy life, it is essential to drink the right quantity and quality of water.

Water plays a vital role in one’s life. It is required not just for our own survival but also for the proper functioning of our planet. All fruits and vegetables contain abundant water in them. To stay healthy, it is needed to have plenty of water, i.e., approximately 3–4 litres of water per day. The human body needs water, and a lack of it can result in major health problems. Kidney stones are a serious health problem caused by insufficient water consumption. Water has the ability to heal and is necessary for life to exist. Our planet is the only place where life is conceivable since water and all of the other essential elements for life are present. Planets, such as Mars, Mercury, and Venus, are uninhabitable. They resemble a desolate desert since there is no water. Water is necessary for life, and it also helps to keep the environment clean.

Water is a precious resource. Water scarcity is one of the most serious issues in the Middle East and even in some parts of India. There is a scarcity of drinking water. Water pollution has lowered the amount of accessible drinking water on the earth’s surface, as well as damaging the quality of the water. It affects not only human beings but also animals, birds and plants.

Water’s relevance can be seen in the context of the current water crisis. Drought is one of the unlucky situations that might occur in a location. The region’s economic and financial conditions will be badly impacted. Excessive rain, on the other hand, is a concern for people, animals, and even farmers and manufacturers. Water is thought to be a blessing, yet it can also be a curse.

Therefore it is essential to value the importance of water. With the increasing global warming, population, and deforestation, fresh water is being polluted, and the amount available to us is diminishing. The water is being misused due to overpopulation. Water, in many forms, depicts the natural beauty of the world. Water sculpts the beauty of nature as well.

Body of Essay 

Water is one of the most basic necessities for survival just as is oxygen for all humans and animals on Earth. Our Earth is made up of 70% water which earns itself the name, the “Blue Planet" as water appears blue from space. The uses of water are not limited to drinking but also for a wide range of other purposes like washing, cleaning, production of electricity and a lot more. But due to misuse of water, it is getting polluted because of our own deeds. This has created many problems for humans and animals alike. 

Due to plastic pollution in water bodies, marine life like tortoises and seagulls often choke on them and die of suffocation. This is creating an imbalance in nature.

Out of all the water that is available on Earth, most of it is too salty and unfit for drinking. Only 1% of the water available is fit for drinking which is coming under threat due to water pollution and droughts in several places. Many urban nationals are going to face a severe water crisis in about 10 years.

Water is also used in the agricultural sector apart from household uses such as cleaning, washing, drinking, etc. In the agricultural sector, feeding and maintaining livestock, and for crop production, water are highly essential.

Even in industries, water is used in the manufacturing and production of several goods which use the water available for us.

The dumping of waste materials has added to the woes of water pollution. Factories, households and livestock dump wastes in water that could otherwise be used for various purposes after proper treatment.

In India, several places are facing droughts and water shortages already. So it is very important for people to understand the need for water conservation and use water judiciously. Even individual help can prove vital in the future. Measures should be taken in water conservation such as:

Do not keep taps running when not in use, repair leakages immediately.

Utilize a full load of washing machines instead of washing fewer clothes, this will help save water each time.

Many public places such as restaurants, hotels and residential buildings have installed fountains which leads to a lot of wastage of water. This should be curbed totally.

Reducing shower time can also cut down on water usage.

Collecting and harvesting rainwater during the rainy season should be practiced which is very beneficial in water conservation. It can be used for a range of purposes such as cleaning, washing and flushing.

Watering lawns should not be practiced as it leads to immense loss of water.

With correct individual and collective approaches, it is possible to help conserve water and thus save the environment. One small step a day goes a long way. Everyone should practice water conservation methods to help reduce water shortages.

FAQs on Save Water Save Earth Essay

1. What is Water Conservation?

Water conservation refers to the processes involved in the development, control, and preservation of water resources. It involves the preservation of both surface water and underground water. Reducing pollution and pollutants is also an aim of systematic water preservation. A well-planned water conservation system can help keep the water clean and pure. Also, it encourages all to use water resources responsibly and wisely.

2. When is World Water Day Observed?

Since 1993, the United Nations have marked 22nd March or every year as World Water Day. This day aims to spread a systematic awareness of the need to conserve water. Also, on this day, several delegates discuss the present scenario of freshwater management and the possible measures to ease the issue. Even in India, the government focuses more on ensuring freshwater supply, planning for better drainage to check floods, and upgrading greenery as measures to improve water resources.

3. How can School Children Help in Water Conservation?

Even in school, young children can start by practising simple water-saving measures. Also, the teachers can encourage them to set up water-saving clubs where they can regularly perform skits, write songs and poems, and the like, focusing on the need to save water. They can be encouraged to be aware of their juniors about the necessity to save water, as well.

4. Why is water pollution harmful?

Water pollution is a big threat that the world is facing today. People living in rural and semi-urban areas wash clothes, bathe themselves and animals in nearby water bodies such as ponds, lakes and rivers which adds to water pollution. In urban areas, factories dump all their harmful wastewater into nearby water bodies without proper treatment which degrades the quality of water and all the water that could otherwise be used for drinking purposes goes to waste. People in India are already facing huge water shortages and droughts, water pollution everywhere only adds to the woes of the common people.

5. How can individuals work together to conserve water?

Individuals can take small steps to make a huge difference:

Try conserving rainwater and harvesting it for everyday uses like cleaning and washing instead of using normal water as it would still get the work done without having to use up good quality water that could otherwise be used for drinking purposes.

Water is used to produce electricity, therefore, we should always try to conserve electricity by switching off lights and bulbs when not in use. Even trying to replace some sources of energy with solar energy as it is eco friendly and is a renewable source of energy.

We should always try to conserve water by not wasting water unnecessarily. We should close taps when not in use and avoid dripping and wastage of water.

Water represents life. Water is a precious resource, a fundamental human requirement, and a valuable asset that all living things possess. Every child should understand the importance of water in daily life.

There are many reasons why water is considered one of the most important and valuable resources on our planet. Let us look at this in a more detailed manner.

Significance Of Water

Water is the cornerstone of human survival when it comes to life. A human body requires water every single day. We might be capable of not eating for seven days; however, we won’t last even three days without drinking water. Furthermore, approximately 60% of human bodies are made up of water which aids our body’s normal functioning. As a result, ingesting impure water will cause major health issues in humans. Therefore, the amount and quality of water we drink are critical to everyone’s physical health and wellness.

Furthermore, our everyday activities would be incomplete without water, like brushing our teeth or preparing meals. Also, many companies use water on a massive scale as almost every single activity of their procedure requires water.

Water has an important function in the lives of all living organisms. From the tiniest insect to the largest whale, each life requires water to stay alive. Water is not just a human need but also flora and fauna. Water is necessary for the planet’s life to function. We should not be self-centred and utilise it for our purposes without caring for the consequences.

Water For Life Processes

• Water plays a crucial part in most biological functions as a solvent. Several waste materials are also eliminated as a solution via urination and sweat.
• Water aids in maintaining body temperature. We take plenty of fluids when it’s hot outside, which keeps the body temperature stable. Water also escapes from the body’s surface as sweat, which removes heat from the body and gets to normal temperature.
• Water is required for plants to make food.

Uses Of Water

• In our daily lives, water is utilised for drinking, dishwashing, baking, showering, and wiping.
• We need water daily for our home gardens too.
• A hydroelectric power plant uses water to create energy.
• Water is being used to irrigate crops and create a variety of items.
• Many water sports include swimming, sailing, kayaking, etc.
• Water can also be used to put out fires.
• Water is necessary for the correct operation of farmed fish, dairies, and many other non-farm operations.
• The majority of fresh water is frozen.
• The oceans contain just about all the water on the planet.
• The salt content of salty water fluctuates.
• One single drop could hold a great deal of life.
• Comets might have also provided some water in the earth’s history. 

Your child will learn how to improve their writing and creative abilities. They will also discover how important water is for their bodies and the ecosystem and the various ways they might use it. They will learn about the importance of water on this planet, not just for humans but for all living things. Last but not least, students will learn about several water-related facts.

1. What Will Happen If Water Vanishes?

Complete vegetation would die rapidly without water, making the earth brown instead of greenish-blue. As clouds will fail to develop and there will be no rainfall, the climate will be dominated entirely by atmospheric circulation. Life as we know it would cease to exist. 

2. Why Should We Not Waste Water?

Water is scarce, despite its abundance, and cannot be regenerated. We must utilise it with caution.

To summarise, water is indeed the foundation of all living things on the planet. Recognising fresh water’s importance and educating people about it is necessary.

Water is crucial for all components of life which makes it a necessary resource for day-to-day activities. We use water for domestic activities like cooking, bathing, drinking, washing, etc. So, ultimately the consumption of water is very high. This makes it necessary to conserve water. Just as air, water is also important for life. Besides, water consumption, water pollution, and water scarcity are also some of the major water-related issues that need attention so that we can conserve water.

Every year we celebrate World Water Day on 22 March. This day is celebrated to spread awareness about the importance of water and run campaigns to conserve water on Earth. There are several ways to conserve water such as switching to showers, turning off taps when not in use, don’t pollute water bodies, storing rainwater, etc.

Essay on Water Conservation in 200 Words

Water is one of the Earth’s most precious resources. But the world is facing water scarcity. As per the SDA report 2022, around 2 billion people worldwide are lacking safe drinking water. This means they are more vulnerable to diseases and unhealthy life. 

Apart from the increasing population, climatic change is also hampering the quality of water. Floods and Droughts are more frequent due to the vulnerability of climate, thereby increasing the need to conserve water.

Water conservation is vital to meet the growing global demand for fresh water. Water consumption is very high for agriculture, industry, and households. By conserving water, we can ensure that there is a surplus amount of water to use and avoid conflicts over this limited resource.

Water conservation helps to maintain a balance in the ecosystem because every living thing on this planet is directly associated with the use of water. Reducing water consumption reduces the energy footprint associated with water supply.

The best ways of water conservation are rainwater harvesting , installing water plants, reusing water for gardening purposes, turning off taps when not in use, proper irrigation, installing automatic tap shut-off devices, not polluting water sources, and many more.

If we don’t want to witness the world die due to water scarcity then, it’s high time to conserve water and save the planet and future generations.

Water Conservation Essay 250 Words

Water conservation is a crucial step in protecting the environment. It is an important compound that supports life on Earth. The world has been facing water-related disasters due to scarcity of freshwater. 70% of the earth as well as the human body is composed of water, but there is a limited amount of freshwater to use. Owing to the ever-increasing population, climatic changes, global warming, and pollution, the need for the conservation of water is increasing. To do so, it is our fundamental duty to conserve water by planting more trees, managing water plants, storing rainwater, and making smart use of water. 

Water Scarcity

Water scarcity is a critical global issue that needs strict attention when the demand for freshwater exceeds the available supply of water. It can manifest in various ways, including a lack of access to clean drinking water, inadequate water for agriculture and industrial processes, and stressed or depleted natural water sources. 

Here are some factors that contribute to water scarcity:

• Climate change
• Growing population
• Global warming
• Inefficient water management
• Water pollution
• Increasing demand
• Poor irrigation techniques
• Wastage of water, and much more.

Ways to Conserve Water

Conserving water is crucial to help address water scarcity and ensure a sustainable water supply for both present and future generations. You can contribute individually by taking small measures to conserve water like turning off the tap. Likewise, here are some ways to conserve water:

• Drip irrigation technique
• Soil management
• Plantation of drought-tolerant crops
• Apply Mulching
• Recycle and reuse water
• Rainwater harvesting
• Desalination
• Spread awareness to conserve water
• Donate to the water cleaning campaign
• Implement proper water management techniques.

• 4.1 Rooftop Rainwater Harvesting
• 4.2 Rainwater Harvesting From Open Spaces Around Buildings

Groundwater

Most of the water on the earth is in oceans. The ocean water is highly saline (highly salty) due to which it cannot be used directly (for drinking, irrigation and in industry). Only a small fraction of water is available on the earth is fit for use by human beings, animals, and plants. This is available in rivers, lakes, ponds and as groundwater.

Availability of Ground Water

The groundwater is available everywhere but when it is used too much for agriculture and other purposes, the level of ground water decreases drastically and hence it cannot be used anymore.

As the population is increasing rapidly, the number of people using water is also increasing rapidly. Due to this, the demand for water is increasing day by day. Also more and more water is being used in agriculture for producing food and by the industries which manufacture a large variety of products for our use.

To conserve water means ‘to save water by using it carefully, wisely and by preventing its wastage. It is essential to conserve water because the amount of usable water on the earth is limited and there is scarcity of usable water for various purposes.

Various ways to conserve water or minimise the wastage of water at home

(1) Turn off the tap immediately after use. Get the leaking taps repaired immediately.

(2) Take bath by filling water in a bucket and not directly under the flowing tap.

(3) Wash the utensils by filling water in basin and not under the running tap.

(4) Use the water from washing rice, vegetables or fruits for watering the plants at home.

(5) Do not use a full flush from the cistern in the toilet when a half flush is sufficient.

Rainwater Harvesting

The activity of collecting rainwater directly and store it in big tanks for later use, or making the rainwater percolate into ground more efficiently to recharge the groundwater, is called rainwater harvesting.

The two main techniques of rainwater harvesting are:

(1) Collection and storage of rainwater in tanks for future use when there is scarcity of water, and (2) To make rainwater percolate into the ground more efficiently by constructing percolation pits and recharge wells so as to recharge (or replenish) groundwater.

Rainwater harvesting can be done in two ways:

(1) Rooftop rainwater harvesting, and (2) Rainwater harvesting from open spaces around buildings.

Rooftop Rainwater Harvesting

Rooftop rainwater harvesting can be done for two purposes:

(1) Collecting rainwater falling on roof and storing it in big tanks for later use.

(2) Collecting rainwater falling on roof and making it percolate into ground to recharge groundwater.

The rainwater collecting on the roof of a house is brought down-through rainwater pipe and collected in big underground tank made of concrete. This water may contain soil particles from roof and needs to be filtered before use. The stored rain water can be used in times of water scarcity.

In the second method of rooftop rainwater harvesting, the pipe bringing down rainwater collecting on the roof of a house (or building) goes directly into a percolation pit made in the ground. The percolation pit has a layer of broken bricks at the bottom; a layer of gravel in the middle and a layer of coarse sand at the top. It is covered by a concrete slab. A narrow bore (or hole) about 3 metres deep is dug into the ground. The outlet pipe coming out of percolation pit is put in this bore.

The rainwater which collects on the roof of a house is brought down by rainwater pipe into the percolation pit. This rainwater gets filtered by the sand, gravel and broken bricks in the percolation pit.

The filtered rainwater comes out of the percolation pit through the outlet pipe. The outlet pipe takes the rainwater deep into ground where it can easily seep into the soil. Whenever the depth of clay soil is more, rooftop rainwater harvesting to recharge groundwater is done through percolation pit with deep bore.

Rooftop rainwater harvesting collects only a small amount of rainwater at a time which can seep into the soil quickly through a percolation pit with a narrow bore. If rainwater harvesting is done from large, open spaces around buildings, then a very large amount of rainwater collects in a short period of time which cannot be absorbed into soil by a percolation pit with a narrow bore. A percolation pit with a wide recharge well is used. 

Rainwater Harvesting From Open Spaces Around Buildings

The rainwater harvesting from open spaces around the buildings in a city is done by constructing percolation pits covered with concrete slabs having holes in them, and connected to a recharge well through a pipe. The rainwater falling in the open spaces around buildings goes into the percolation pit through the holes in its concrete slab cover. After filtration in percolation pit, rainwater enters the recharge well through the outlet pipe and gradually seeps into the soil.

The main purpose of rainwater harvesting is not to hold rainwater on the surface of earth but to make rainwater percolate under the ground more efficiently so as to recharge (or replenish) groundwater.

The advantage of rainwater harvesting is that it increases the availability of groundwater and helps in overcoming water shortage.

Short Essay on Importance of Water (200 words)

Water is available in abundance on Earth. It is present on the surface of Earth as well as beneath it. The water bodies present on Earth’s surface include rivers, ponds, seas and oceans. The surface water evaporates due to the excessive heat of Sun. It is circulated in the atmosphere and forms clouds that burst and reach the Earth’s surface in the form of rain. Thus, the water that evaporates gets replenished by the natural process of water cycle which occurs continuously. This helps in maintaining the eco system and makes our planet worth living.

While Earth is filled with plenty of water, fresh water is very small part of it and its amount is only decreasing by the day. It is sad but true that due to various human activities and human negligence, the water present on Earth is getting polluted. Fresh water is getting depleted as the water bodies are being polluted due to industrial as well as domestic waste.

It is high time we must understand the importance of water in our lives and the necessity to save it. There are many simple ways in which we can avoid wastage of water such as bathing with less water, watering plants with waste water from RO, cleaning the car with a wet cloth rather than pipe, etc. We must also use the method of rain water harvesting to collect rain water. This way we can contribute our bit to save water.

Essay on Important Uses of Water (300 words)

Introduction.

Water is available in abundance on Earth. It is one of the main reasons which make life possible on our planet. Available from different sources, water is an essential requirement for all the living beings. It is used for various purposes by human beings. Here are some of the important uses of water.

Different Uses of Water

• Drinking: Drinking water is vital for the survival of living beings. So, one of the main uses of water is drinking.
• Cooking: Water is also used for the purpose of cooking. Many recipes such as lentils, rice, soups, etc require water. Besides, even the vegetables and fruits that do not require added water for preparation need to be washed thoroughly before eating/ cooking.
• Cleaning: Whether it is cleaning a house, office, car, machinery or anything for that matter, it is not possible without using water. All the cleaning tasks require water.
• Washing: Water is also required for the purpose of washing clothes, utensils and various other things.
• Sanitation: Water is also required for the purpose of sanitation. It helps in maintaining cleanliness and hygiene.
• Agriculture: A major share of water on Earth is used for the purpose of agriculture. It mainly used for irrigating the farms to keep the land fertile and ensure adequate supply to the crops. It also used for rearing the livestock.
• Industries: Industries use water for various purposes. The manufacturing of many products require water. It used in the transportation, fabrication and processing of various products. Some of the industries that need good amount of water include pulp and paper and engineering industries.

Water used for different purposes in homes and offices. It is as much essential for other living beings as it is for the humans. Therefore it is one of the main reasons we are alive. Is impossible to imagine life without water.

Essay on Importance of Water: Water Cycle (400 words)

Water is present in solid, liquid and gaseous forms on Earth. All three forms of water are essential to maintain our planet’s ecological balance. Water is in high demand as it used for various purposes. Fortunately, we have many sources of water including seas, rivers, oceans and rain. Water replenishes itself naturally and constantly by way of water cycle thereby maintaining balance in the atmosphere.

Why is Water Cycle Important?

Water needed for the survival of the living beings. Be it plants, animals or human beings – all three require water. While plants and animals mainly require water for the purpose of drinking or as habitat, human beings use water for several purposes. Water would have long vanished from the face of Earth if the process of water cycle hasn’t existed.

The process of water cycle involves different steps. These are evaporation, transpiration, condensation, precipitation and surface run off. Water evaporates from different sources including oceans, seas and rivers due to sun’s heat. Water vapours rise into the atmosphere. Slowly these vapours cool down and condense to form clouds.

When large amount of vapours join together, the cloud becomes heavier and falls in the form of rain. This way the water falls back on the surface of Earth. It gets accumulated in rivers, lakes, oceans, layers of rocks and soil. This completes the process of water cycle. The water collected in oceans and other water bodies once again evaporates and the entire cycle reoccurs. This is an ongoing process. Water cycle also impacts the weather condition on Earth. The cycling of water in the atmosphere regulates the weather patterns.

Important Sources of Water

Sources of water have broadly divided into two categories:

• Surface Water: This found in rivers, lakes, streams, seas, oceans and also reservoirs. The downpour from the clouds and the melting of snow from the mountains fill the rivers and the lakes. Rivers flow continually and also meet the sea. The sea water flows into the ocean. Surface water evaporates and enables the water cycle process.
• Ground Water: Ground water is present under the Earth’s surface. Water seeps under the land via porous rocks and soil. This water gets stored under the Earth’s surface and extracted by digging wells and also constructing tube wells.

Water cycle makes sure the lost water replenished on the planet and is available in abundance for all the living beings. If this process did not occur naturally we would not have sufficient water on our planet.

Essay on Importance of Water – An Essential Part of Our Life (500 words)

Water is an essential part of our ecological system. It is one of the main substances that make our planet fit for living. Water is essential for the growth and development of plants and animals. However we use water directly as well as indirectly for many of our needs.

Water – An Essential Part of the Human Body

Research shows that up to 60% of the human body made of water. Our lungs are around 83% water, our muscles and kidneys are 79% water, our brain and heart are 73% water, our skin contains 64% water and our bones have 31% water. Water helps in several functions of the body including blood circulation, digestion, regulating body temperature, protecting tissues and joints and also excreting waste via perspiration, defecation and urination.

Our body continually uses water to perform these functions. So, we need to provide a continuous supply of water to our body to help it function well. It is important to replenish the lost water timely.

Water – Vital for Plant Growth

Plants prepare their food by way of photosynthesis. Water forms an essential part of this process. As we water the plants, it enters their stem and moves up to their leaves. However it draws nutrients from the soil and carries them to the leaves. Photosynthesis takes place in the leaves. The water present in the leaves evaporates and exchanged for carbon dioxide.

Without proper supply of water, the plants do not get enough nutrients and photosynthesis cannot take place. As a result, the plants begin to droop and fall. Different kinds of plants require different amount of water at different times. While some plants need to watered twice a day others require water once a week while there are yet others that can go weeks without water especially during cold and moist season.

Water – Habitat for Marine Creatures

Water serves as home for the marine creatures. Wide variety of fishes, turtles, frogs, crabs and other marine creatures live in seas, oceans and rivers. These water bodies are their habitat. Most marine creatures live solely in water and cannot survive on land. They add to the biodiversity and also are an essential part of the eco system.

The increase in the level of water pollution is causing a threat to these beautiful and innocent creatures. Many species of the beautiful marine creatures have either gone extinct or endangered. Water pollution caused due to various human activities. It needs to controlled in order to provide a safe and healthy habitat for the marine creatures.

Water is vital to the survival of living beings. Even as water recycles naturally, the amount of fresh water on Earth is depleting fast. This is all because of the negligence of human beings. We use water for several purposes throughout the day. But we aren’t using it efficiently. We waste it more than we use it. This is the reason why water is decreasing at a rapid speed. It is high time we must use water wisely and limit the activities that pollute it.

Long Essay on Importance of Water (600 words)

Water is among the most essential substances on Earth. Two third of Earth covered with water; however, only a small part of it fresh water which is fit for human use. The growing pollution is polluting the fresh water too, thereby making it unfit for any kind of use. Besides, fresh water available for use often wasted during various activities. This has become a global cause of concern. It is time we should understand the importance of water and also try to save it.

Conversation of Water

In this era of growing water pollution, we need to watch out our activities. Fresh water is getting scanty mainly due to two reasons. One of these is the increasing level of water pollution caused due to industrial waste and various other human activities and the other is the continuous wastage of water by people around the world.

We must conserve water otherwise it will become difficult for us to survive on Earth in the times to come. Water is essential to maintain the ecological balance and create an atmosphere which is appropriate for us to survive. It also needed for drinking, cooking, cleaning, irrigating the fields and various other activities. We need to save water and put it to correct use.

Methods to Conserve Water

There are many ways in which we can conserve water. Several activities that we indulge in our daily lives can done differently to save water. Here is a look at these:

• We often keep the tap on while we brush our teeth. This results in a lot of wastage of water. Turn the tap on only when you require it, else keep it off. A lot of water that goes down the drain unnecessarily will saved this way. Practice the same while washing your hands as well.
• It is best to use bucket while bathing as a lot of water wasted while taking shower. Or you can keep a tub under the shower when you don’t require water while taking shower. This water can used for watering the plants or flushing.
• The waste water from RO can collected in a bucket and used to water the plants or for cleaning purpose. You can also do the same with the water left after boiling potatoes, noodles and pasta. This water is hot and can very well used for cleaning oily and greasy utensils.
• Water the plants during evening or early morning hours so that the water absorbed properly and does not get evaporated fast. This way you will require less water for watering the plants.
• Do not make use of water to defrost food items.
• Instead of using a pipe to wash your car, it suggested to use a bucket and wet cloth. You can also get it washed regularly from a car wash service that uses recycled water for this purpose.
• Rainwater harvesting is a good way to store water and to put it to good use.
• Install water efficient appliances such as low flow bathroom fixtures, sink systems, dish washers and washing machines and use them wisely to save water. For instance, make sure your washing machine and dish washer completely loaded before you turn them on.
• Do not neglect any leakage in your kitchen, bathroom or any other part of your house. Get it fixed immediately to avoid wastage of water.
• Using less electricity is an indirect way to save water. This is because power plants use several gallons of water.

Conservation of water must taken seriously. The government of every country should restrict activities that result in water pollution and wastage of fresh water and the citizens must provide complete support in this direction. Each one of us should realize the importance of water and take it as our responsibility to use the simple ways mentioned above to conserve water.

Essay on Water Pollution for Students and Children

500+ words essay on water pollution.

Water is the most important resource for survival on a planet. It is the essence of life on our planet – Earth. Yet if you ever see a river or lake around your city, it would be evident to you that we are facing a very serious problem of Water pollution. Let us educate ourselves about water and water pollution . Two-thirds of the Earth’s surface is covered by water , seventy-six perfect of your body is made up of water.

Water and Water Cycle

As you already know water is everywhere and all around.  However, we have a fixed amount of water on earth. It just changes its states and goes through a cyclic order, known as the Water Cycle. The water cycle is a natural process that is continuous in nature. It is the pattern in which the water from oceans, seas, lakes, etc gets evaporated and turns to vapor. After which it goes through the process of condensation, and finally precipitation when it falls back to earth as rain or snow.

What is Water Pollution?

Water pollution is the contamination of water bodies (like oceans, seas, lakes, rivers, aquifers, and groundwater) usually caused due to human activities. Water pollution is any change, minor or major in the physical, chemical or biological properties of water that eventually leads to a detrimental consequence of any living organism . Drinking water, called Potable Water, is considered safe enough for human and animal consumption.

Sources of Water Pollution

• Domestic Waste
• Industrial effluents
• Insecticides and pesticides
• Detergents and Fertilizers

Some of the water pollutions are caused by direct Sources, such as factories, waste management facilities, refineries, etc, that directly releases waste and dangerous by-products into the nearest water source without treating them. Indirect sources include pollutants that infuse in the water bodies via groundwater or soil or via the atmosphere through acidic rain.

Effects of Pollution of Water

The effects of Water Pollution are:

Diseases: In humans, drinking or consuming polluted water in any way has many disastrous effects on our health. It causes typhoid, cholera, hepatitis and various other diseases.

Eradication of Ecosystem: Ecosystem is extremely dynamic and responds to even small changes in the environment. Increasing water pollution can cause an entire ecosystem to collapse if left unchecked.

Eutrophication: Chemicals accumulation and infusion in a water body, encourages the growth of algae. The algae form a layer on top of the pond or lake. Bacteria feed on this algae and this event decreases the amount of oxygen in the water body, severely affecting the aquatic life there

Effects of the food chain: Turmoil in food chain happens when the aquatic animals (fish, prawns, seahorse, etc) consume the toxins and pollutants in the water,  and then the humans consume them.

Prevention of Water Pollution

The best way to prevent large-scale water pollution is to try and reduce its harmful effects. There are numerous small changes we can make to protect ourselves from a future where water is scarce.

Conserve Water: Conserving water should be our first aim. Water wastage is a major problem globally and we are only now waking up to the issue. Simple small changes made domestically will make a huge difference.

Treatment of sewage: Treating waste products before disposing of it in water bodies helps reduce water pollution on a large scale. Agriculture or other industries can reuse this wastewater by reducing its toxic contents.

Use of environment-friendly products: By using soluble products that do not go on to become pollutants, we can reduce the amount of water pollution caused by a household.

Life is ultimately about choices and so is water pollution. We cannot live with sewage-strewn beaches, contaminated rivers , and fish that are poisonous to drink and eat. To avoid these scenarios,  we can work together to keep the environment clean so the water bodies, plants, animals, and people who depend on it remain healthy. We can take individual or teamed action to help reduce water pollution. As an example, by using environmentally friendly detergents, not pouring oil down the drains, reducing the usage of pesticides, and so on. We can take community action too to keep our rivers and seas cleaner. And we can take action as countries and continents to pass laws against water pollution. Working together, we can make water pollution less of a problem—and the world a better place.
