madreJ [45]

Answer: B. great impact when humans use alternative water sources for non drinking functions.

Great impact when humans use alternative water sources for non drinking functions is the correct option because use of alternative water sources can deplete the overall available water for the present as well as for the future generation of the human population. This is against the concept of sustainable development which suggests that natural resources should be used in such a way so that these can meet the needs of the present population as well as that of future generation.
