Essay on Importance of Water

Water means Life. Water is a prime natural resource. It is a basic need for humans and a precious asset that living beings have. Water is equally vital for the survival of plant and animal kingdom. Soil needs water for sustaining plants. The water cycle is essential for ecological balance too. Though a big portion of the Earth is covered with water, only a small portion of it can be used for various human activities. So we need to be judicious and rational, regarding the usage of water .

Why is water important for our Body?

Water is important for our body for the following reasons. 

  1. Above 70% of our body contains water so it is pivotal for the human race to survive. 

  2. Water helps in regulating our body temperature. 

  3. Water helps in the digestion of solid food. 

  4. It also keeps our skin healthy and hydrated. 

  5. Water helps in excreting waste from our body through sweat, urination, and defecation. So replenishing the water in our body is essential in order to prevent dehydration.

  6. Drinking water also helps in reducing calories and maintains body weight because it can increase the rate of metabolism.

  7. Water consumption lubricates the joints, spinal cord, and tissues.


Importance of Water

All living organisms, plants, animals, and human beings contain water. Almost 70% of our body is made up of water. Our body gets water from the liquids we drink and the food we eat. Nobody can survive without water for more than a week. All plants will die if they do not get water. This would lead to the death of all the animals that depend on plants for their food. So the existence of life would come to an end. 


Role of Water In Life Processes

  • Water plays an important role in most of the life processes by acting as a solvent. The absorption of food in our body takes place in solution form with water as the solvent. Also, many waste products are excreted in the form of solutions through urine and perspiration. 

  • Water helps in regulating our body temperature. In hot weather, we drink a lot of water. This maintains our body temperature. Also, water evaporates from the surface of our body as sweat. This takes away heat and cools the body. 

  • Water is essential for plants to grow. Plants need water to prepare food. They also absorb dissolved nutrients from the soil through their roots. 

  • Aquatic plants and animals use the nutrients and oxygen dissolved in water for their survival. 


Uses of Water In Everyday Life

  • Water is used for drinking, washing, cooking, bathing, cleaning, in our day-to-day life.

  • It is used to generate electricity in hydroelectric power stations.

  • Water is used for irrigating fields and in the manufacture of various products. 


Other Uses of Water

  • Water serves as a means of transportation for goods and people.

  • It provides a medium for recreational sports such as swimming, boating, and water skiing. 

  • Water is also used to extinguish fires. 


Importance of Oceans

Oceans are of immense use to man. They are useful in many ways, directly and indirectly. They not only play a significant role in the climate of adjoining countries but also serve mankind in many ways. They are a storehouse of several resources. 

  • An ocean is a major source of water and forms a major part of the water cycle. Oceans contribute water vapour to the atmosphere and we get the same in the form of precipitation.

  • The oceans are the biggest storehouse of edible forms of marine food, fish being most important. In addition to food, sea animals provide other products like oil, glue, etc.

  • Oceans have enormous mineral and chemical wealth. A variety of dissolved salts like sodium chloride (common salt), magnesium chloride, and potassium chloride are found in plenty in the oceans.

  • Oil and gas are important fuels obtained from oceans.


Importance of Lakes and Rivers

  • Economic and industrial development

  • Water storage

  • Hydroelectric power generation

  • Agricultural purposes

  • Modern multipurpose dams

  • Source of food

  • Source of minerals

  • Tourist attractions and health resorts

  • Rivers provide fresh drinking water

  • Ports can be built on them as they form good natural harbours 


Major Concerns

Although our planet Earth is covered with 71% percent of water and 29% of the land, the fast-growing contamination of water is affecting both humans as well as marine life. The unequal distribution of water on the Earth and its increasing demand due to the increasing population is becoming a concern for all. 

  • Water pollution makes it difficult for marine animals to sustain.

  • Covering over 71% of Earth’s surface, water is undoubtedly the most precious natural resource that exists on our planet. Without the seemingly invaluable compound comprising Hydrogen and Oxygen, life on Earth would be non-existent. 

  • We are slowly but definitely harming our planet at a very alarming rate. 


Conclusion

Human beings should realize how important and precious water is. At the individual level, you can be more responsible and avoid wasting water so that our future generation can make the best use of this natural resource abundantly.
