please tell me an essay on water conservation for class 7

Answer:
hi which school
Explanation:
Only three percent of the total water available is freshwater. But more than sixty percent of this potable water is locked up in ice caps and glaciers. Therefore, we humans must consume water judiciously.
But so far, we have done the reverse. We exploit water extensively for agriculture and industrial purposes.
Moreover, we haven't kept our water bodies clean. Industrial effluents and sewage discharges are directly let into rivers. In cities, buildings come up on dried ponds and lakes.
So, when it rains, we don't have the facility to store the rainwater. Therefore, we not only have frequent flash floods, but the rainwater goes to the sea and gets wasted. We use the fertile soil from riverbeds carelessly, and it leads to flooding in riverine areas too. So, we humans are primarily responsible for reducing the holding capacity of water bodies.
We live in concrete jungles, and a green cover is almost missing in our cities. It is the roots of trees that help in the retention of groundwater. Moreover, plants release oxygen and absorb carbon dioxide.
Thus, they are instrumental in curbing global warming. Lesser warming implies a slower melting of ice sheets and glaciers, thereby, preserving the largest source of fresh water.
Floods and storms are natural events, but nature has its way of replenishing the water that flows into the seas. But we humans have a history of clearing up forests for various purposes like agriculture, industrialization, and human settlements.
We cannot imagine living without water. Water is vital for a healthy body. We can survive without food for a few days but cannot live without water — we need it for cooking, cleaning, and for using the toilet too.
Non-availability of water in landlocked regions could become a threat to survival for most of the species there. Consumption of unclean water leads to many diseases such as cholera and diarrhea.
Tiny drops of water make the ocean vast. So, every drop of water saved is a step towards saving life on the blue planet. Our governments come up with effective strategies for conserving water.
However, the issue persists and is a global crisis. John F Kennedy once quoted that whosoever solves the water-crisis should get two Nobel prizes, one for Science and the other for Peace.
The scientific communities need to work on advanced agricultural reforms in irrigation, development of drought-resistant crop varieties, and desalination of seawater.
Proper planning of cities and efforts to keep the water bodies clean are an absolute requirement. But all these measures need to be cost-effective, and governments must ensure that the developments reach the end-user for reaping maximum gains.
The government should also come up with bold measures such as curbing advertisements that depict the wasting of water such as the use of the shower etc.
