Answer:
Ans. After
independence industries are increasing in a rapid pace and become a reason for
pressure on existing fresh water resources.
Fresh water is almost limited, though renewable, in India but over-exploitation
and mismanagement of this resource by industries is aggravating the water
stress day by day.
(i) Industries especially heavy industries use huge amount
of fresh water for industrial purpose and pollute and waste such water.
(ii) These industries, for their energy consumption
purpose depend on hydroelectric projects where electricity is generated through
damming the rivers upstream. So, the river almost dries in the lower stream
areas.
(iii) Again industries dump the chemical waste in the
river, lake etc, which then consequently pollute the water dangerously for
human survival. These also contaminate the ground water through industrial
wastes.
So the increasing number of industries exert pressure on existing
fresh water resources.
