Water is a precious natural resource. All living things need water for their survival. We cannot imagine life without water. Let it be animals or plants they require water to complete their daily metabolic activities. Plants require water to synthesize their food from the process of photosynthesis.
On average, an individual uses 600 to 700 litres in a day. We all can live without food for days together but cannot even imagine surviving without water, even plants become dry and shed their leaves without water.
Let us learn some more importance to water.

What is Water?
Water is one of the natural resources, which are found in an adequate amount. It is an essential source for the existence of life on the planet earth. It is widely used for various purposes such as drinking, washing, bathing, cleaning, cooking, irrigation, and other industrial and domestic uses.
Sources of Water
There are various sources of water. About 97% of the water on the Earth’s surface is covered with water. The three main sources of water are:
- Groundwater – This includes water bodies like Wells and Springs.
- Surface water – This includes different water bodies like Reservoirs, Rivers, Streams, Ponds, Lakes and Tanks.
Importance of Water
We all need water for different daily activities including:
- Domestic Purposes include bathing, cleaning, cooking, drinking, and washing.
- Agricultural applications include irrigation, farming, gardening, and frost control.
- Other Industrial Applications.
Apart from this, we drink water to:
- Stay hydrated
- Lubricate Joints
- Regulate the body’s temperature
- Transport nutrients and other waste in the body.
- Balance the loss of water from the digestive tract and body tissues.
Water Cycle
Water never stops moving. The water cycle mainly describes the process of the continuous movement of water from the surface of the earth and it is usually carried out in four different stages. The entire cycle is controlled by the sun and is also known as the hydrological cycle
Evaporation : In this stage, the heat from the sun heats up the water from oceans and other water bodies and evaporates the water in the form of vapours which rises up and form clouds.
Condensation : The water vapour’s in the clouds cools down.
Precipitation : The cooled water vapours in the clouds form droplets and released in the form of Precipitation back to the earth surface in the form of rain or snow.
Collection : The rainwater runs off to the ground and gets collected into the river, ponds, well, and back to the sea.
As mentioned above, about 97% of the water on the Earth’s surface is covered with water. Only 2 to 3% is available and safe for drinking. Rest of the water is saltwater and other two-thirds of the Earth’s freshwater is frozen in glaciers and these water resources are mostly inaccessible for human use.
This is the reason, we all need to reduce wasting this natural resource and conserve water for future requirements.

A short paragraph on saving water can help children learn the importance and use of water and how important it is to use it carefully.
Water is a natural resource that is essential for living on earth. Without water, the earth would be dry, and plants, animals, and humans would not be able to survive. Additional uses include irrigation, washing clothes, cooking, cleaning, etc. We all know that water is not an unlimited resource, and it is important we do not waste it. Daily practices like leaving the taps open while brushing, shaving, etc., cause water wastage. We should not throw garbage in water bodies because polluted water bodies affect marine life and human health when we consume seafood. Shortage of water causes diseases and damages agriculture too.
A short essay for classes 1, 2 and 3 will help young ones understand the use of water and the importance of conserving it. It will also enhance their writing skills.
Our planet earth is covered with around 71 per cent water. When seen from outer space, it appears blue and is also called the blue planet. Air and water are what make life possible on earth. Plants, animals, and humans need water to survive. Water is necessary for bathing, cooking, irrigation, washing, etc. Industries like mining, petrochemical, electricity, food, etc., rely on large quantities of water for their activities. However, in recent times we use water as it is an unlimited resource. No care is taken to use it judiciously. Discharging industrial and domestic waste in water bodies causes pollution. It affects marine life too. Water scarcity leads to drought and poverty and impacts the nation’s economy badly. Therefore, steps must be taken to conserve water. Rainwater harvesting, reusing water, awareness programs in schools, closing taps after using them, and disposing of wastes in bins are a few steps we can take as responsible citizens to save water. Storing running water in dams, using water cans instead of hosepipes, installing canals on rooftops, and adopting bucket baths instead of showers are small initiatives that significantly save water. Acting responsibly in this matter will benefit the present generations and the generations to come. So, saving water, saving nature, and saving our future generations should be our motto.
The save water essay for class 3 kids seeks to explain the importance of water in our daily lives, why water is essential for the planet and the activities that cause water pollution in recent times. The importance of a water conservation essay is such that children learn about the problems our planet faces and can act towards making the situation better.
What Is Water Conservation?
Water conservation means the practice of using water efficiently wherever possible, thereby minimising its wastage. It includes all steps taken to preserve water bodies, freshwater sources, and our daily requirements without polluting or wasting them.
Necessity And Importance Of Saving Water
Water, as we all know, is a vital resource for the existence of life on earth. Though its supply seems abundant, the percentage of available freshwater is even less. Global warming and constant climate change have led to delayed rains, causing water scarcity. An increase in population, the rapid development of industries and polluted water bodies have further worsened the issue. Without proper conservation efforts, the chances are that we might exhaust it. Saving water has economic and social benefits. Besides, protecting water resources for future efficient use reduces wastage and contributes to energy-efficient operations.
What Are The Different Uses Of Water?
Water is used for a variety of needs, and the major ones are listed below:
- For daily activities: Bathing, cleaning, washing, and cooking require water on a daily basis.
- Industrial uses: Water is needed in large quantities in mining, food, chemicals, and several other industries.
- Agricultural needs: Watering is essential for the survival and growth of plants.
- Ecosystem balance: The water cycle is important for rains and the balance of the ecosystem.
Causes And Effects Of Water Shortage
1. Causes of water shortage: Around 70 per cent of the earth is covered with water, but only 3 per cent of it is available for use. Therefore the availability is limited, and hence careless usage causes a shortage. An increase in population, rapid industrialisation, and climatic changes are major causes of water shortage.
2. Reasons for freshwater storage and how to store it: The need to keep freshwater stored arises due to careless use in daily activities, pollution of water bodies by dumping sewage, pesticides, chemicals, etc. Rainwater harvesting, installation of canals on rooftops, and utmost care not to waste water during brushing, shaving, and similar activities are a few methods to store it.
3. Effects of water shortage: Water scarcity causes drought and severely affects agriculture, plants, animals, and human beings. Industrial activities will come to a stop without water and, in the long run, affect the economy as a whole.
What Are The Best Ways To Save Water?
- Use rainwater for watering plants, laundry, etc.
- Turn off taps when not in use.
- Participate in save water save nature programmes.
- Water plants in the evening to reduce evaporation.
- Prefer a bucket bath instead of a shower.
- Check for any leaks in taps.
- Use washing machines in full loads.
- Invest in low flush toilets.
- Be cautious while washing cars.
- Don’t wash parking areas or garages daily.
The need to save water is at an all-time high, and educating children about its importance contributes a long way. Through this essay, your child will learn how important water is for lives on earth and the problems water shortage can cause. It also introduces them to water conservation and various steps that can be followed to achieve the same. They will learn how to participate in the idea of saving water by taking small steps to conserve water and thereby help preserve the earth.
Water is what makes the earth habitable; therefore, it is our responsibility to use it judiciously. And we should start sensitising our kids about it.

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.
