Which of these is a way to increase the availability of freshwater
Nastasia [14]

Answer:

Option A

Explanation:

Options -

A-avoid water pollution.

B-build thermal power plants.

C-add water features to gardens.

D-avoid drip irrigation systems

Solution -

The largest source of freshwater on planet earth is underground water. The water beneath the surface of earth is very limited. The total fresh water reserve on earth is 3% of the total water on earth. Pollution due to discharge of waste water into the rivers and oceans has caused the degradation of not only surface water but also ground water.  

Thus, option A is correct

Drip irrigation is a means to prevent wastage of water during irrigation. Thus, avoiding it will cause further loss of fresh water.  

Addition of water feature will increase usage of water, thus it is also incorrect

Building thermal plant will also cause water pollution and wastage. Hence, option  B is also incorrect
