Question

why is necessary to stop rain water?​

Answer 1

Answer:

$If the rainwater is stopped, from flowing away and allowed to percolate in soil or stored, this water will be available for us even after the rainy season. The groundwater level rises due to the percolation of rainwater in the soil. ... Well, the water rises, and more land can be cultivated.}$

Answer 2

Answer:

Factors such as climactic changes happening at a national and global level are causing water levels to fall. Overpopulation has resulted in the increased acquisition and development of land that has resulted in the depletion of our water bodies.

Deforestation has further compounded the deficiency of water, and this causes regional rain to eventually become unpredictable. Several areas are critically affected by a dearth of usable water.

As a result of accelerated property development in our cities, the greatest requirement for critical resources such as water is focused in urban areas. As a consequence, multi-storey residential complexes are being constructed at a rapid speed.

The earth’s surface is 70% water; yet, very little of this is actually usable or drinkable. It is very likely that we will shortly reach a stage when the quantity of usable water present on the earth’s surface won’t be sufficient to satisfy all our requirements.
