Five reasons for water scarcity in India are:
(1) Taking out lot of underground water through tubewell or pump.
(2) Over population means more demand more demands mean more use of natural resources and thus, depelation.
(3) Wasting by opening and throwing water here and there for fun especailly in festival like holi.
(4) Mixing of pure water in chemical dump in the rivers and oceans. Thus, water scarcity of fresh drinking water.
(5) The most important wastage of water by the water tankers who simply open the tap and all the water leaks and goes into the roads etc.
Thus, saving a drop of water is like saving the world from scarcity.
(6) Today the multinational companies and other industrial units consume large quantities of hydroelectric power and for processing which put greater pressure on the existing fresh water resources in India. Multiplying urban areas with dense population and modern life styles have created an ever increasing demand for water and energy resources.
(7) Pollution of water bodies due to discharge of industrial effluents, use of pesticides, insecticides and fertilisers used in agriculture, make the river water hazardous for human consumption.
