Answer 1

Answer:

75% of the earth is covered with water but still there is an urgent need to conserve it because fresh water reserves are only 2.5%. This 2.5 % fresh water is found in the form of ice caps, glaciers, ponds, lakes, rivers and underground water. We basically use surface water that is easily available to us

Answer 2

Answer:

Dear Student,

75% of the earth is covered with water but still there is an urgent need to conserve it because fresh water reserves are only 2.5%. This 2.5 % fresh water is found in the form of ice caps, glaciers, ponds, lakes, rivers and underground water.

Source of fresh water

Percentage

Ice and glaciers

69%

Ground water

30%

Surface water

1%

We basically use surface water that is easily available to us. This surface water is only 1% of the total fresh water available on the earth. This is the reason why there is an urgent need to conserve it.
