Question

What is the cause of the decline of freshwater around us?

• A. Water pollution by throwing garbage in rivers and lakes
• B. Over fishing in oceans
• C. Overpopulation
• D. Cutting of trees

Answer 1

Answer: (A), (C), (D)

The correct options are
A Water pollution by throwing garbage in rivers and lakes
C Overpopulation
D Cutting of trees

Trees releases water vapour through the surface of their leaves by the process of transpiration, which helps in the increase of precipitation. This further helps in increase in freshwater availability. Due to high dumping of plastics and release of chemicals into rivers by industries, water pollution of these rivers causes a decrease in freshwater availability. Overpopulation leads to more consumption of resources, which, in turn, propels waste generation and more water pollution.
