Water is one of the main reasons we are alive. It is essential for the survival of the living beings. It is put to various uses including drinking, cooking, cleaning, washing, irrigation and more.
You will find below a number of short and long paragraphs on Water. We hope these Water paragraphs will help students in completing their school assignments. These will also help children to write and read out paragraphs with simple words and small sentences. Students can select any paragraph on Water according to their particular requirement.
Water is the most precious elixir the mankind possesses. For centuries, it has been easily accessible and thus its importance has been underestimated. Water helps in most of the processes going on in human body.
It is clearly quintessential for the humans. But it is also of prime importance to the other organisms present in our biosphere, namely trees and vegetation, birds, animals and insects. Today, enormous land masses face water scarcity. Clean, potable water is now a luxury instead of necessity in many regions. Therefore, as the most intelligent species living on earth, every individual should strive to realize the importance of this elixir and partake in efforts to conserve it.
Water is the most precious gift to humanity by God. It is the most essential need of humans, animals, insects, plants, birds and other living beings for their survival on this planet. Though 3/4th surface of earth is covered with water only 3% of that is available as fresh water (of which 70% is present as ice sheets and glaciers and only 1% is available as clean drinking water or which fits for human use).
Water is used for all the purposes such as washing, bathing, cooking, watering plants, irrigation, in industries for performing chemical reactions, generating electricity, manufacturing different materials and also in laboratories for performing various reactions.
Thus, because of increasing demand of water in an era of increasing population and finite availability of water, there is a huge requirement to conserve it. Awareness should be created among people to save water which eventually will lead to save life on earth.
The importance of water has been recognized since ages. Because of this the Egyptians built their whole civilization around the river Nile. They knew that the survival and the development of any civilization is possible only because of their ability to use water at its best.
Water cycle
Water is not a major requirement for survival only because it has various uses but also because it is a part of ecosystem. In fact, it has got its own cycle, water cycle, which contributes as a part of ecosystem.
Stages of Water Cycle
Water cycle, also known as hydrological cycle, is the cycle which describes the movement of water on, above and below the surface of earth. There are 5 stages of this cycle: evaporation, precipitation, condensation, transpiration and infiltration or run off. During evaporation, the water present on the surface of earth enters the atmosphere and turns into water droplets by the process called condensation.
By precipitation, the evaporated water again enters earth’s surface which eventually leads to infiltration, the process which helps in increasing ground water level, or run off, by which the remaining water runs down the surface and enters the water bodies. Transpiration is the process of evaporation of water from plants through their aerial parts.
By this hydrological cycle the ratio of water on earth is still able to remain constant, though it is present in different forms and stages.
Water, having remarkable chemical and physical properties, also known as the universal solvent and available in abundance in nature, has innumerable uses.
Water and Its Uses
Here is a look at the various uses of water. It is used in the following ways or areas:
So, apart from serving our basic need of drinking, water is used for various other extremely essential tasks.
Even though water is used for serving almost every purpose of life in one or the other way, and the availability of fresh, usable water is limited as compared to its increasing demand huge amount of water is wasted or polluted in an irreversible way.
Reasons for Water Pollution and its Wastage
Following are some of the ways in which water is contaminated or wasted due to human negligence:
On one hand there are tremendous needs and uses of water, which means tremendous ways to exploit it, and on the other hand there is finite amount of water left in comparison to the increasing demands of increasing population. There is thus a major need to save water.
Save Water – Save Life
Here are some of the ways to save water:
Water is the reason of survival for all the living species on earth. Water, consisting simple molecules made up of two hydrogen atoms and one oxygen atom, helps in building 70% to 90% of human body. It plays a very important role in animals as it helps in the homeostasis process by which the temperature inside the body remains relatively constant. It has maximum density which makes aquatic life possible in regions with extremely low temperature.
Importance of Water
Water is one of the most impactful pieces of nature. We have seen water as a powerful substance and have been able to understand its importance by using it for industrial and agricultural advancements, using it as a means of transportation, for generating electricity, in laboratories, for washing clothes, utensils, cooking food and more. But we have lacked to view the importance of sustaining it on a global scale as it is reducing at an alarming rate now. Though 3/4th of the earth’s surface is covered with water, there is only 3% of it available in pure form and out of that only 1% available for human use.
Exhaustion of Water
Water is getting exhausted at an exponential rate because of pollution and also because we humans are using it without any sustainable planning. With the number of man-made dams across the planet, we have altered the natural waterways forever, and there might be no going back to this. Adding of insecticides, pesticides or any other chemicals from industries in river water can put aquatic life in danger. Not only chemicals, but too much of organic waste can increase the amount of dissolved oxygen at an unacceptable rate for aquatic plants and animals.
What if we Fail to Save Water?
If steps towards true governance of using water sustainably are not taken then there will be massive loss to this planet and it will be irreversible. Pollutants added in water bodies can be the cause of death for the aquatic animals which eventually leads to the death of animals or birds surviving on them. Thus, it will eventually affect the food chain. Humans will also be affected by these processes as they can get diseases such as hepatitis by eating poisoned sea food. By this rate of rivers getting polluted, it is estimated that by 2050, 5 times as much land will be under extreme drought. Also, by then the increased population will demand 19% more agricultural water.
Thus, due to increasing rate of population and their demands of luxury and lack of governance, the chances of survival of living species on earth will tend to become null.
