List four ways in which we can conserve water.
Following are the ways by which we can conserve water and use it effectively:
(i) Using the water effectively, by avoiding wastage and recycling wherever possible.
(ii) Planting more trees and forestation. Trees absorb water from the ground. Hence, balance the water cycle.
(iii) Storing rainwater in large amounts for future use by constructing dams.
(iv) Treating the sewage and industrial wastes before disposing them to the water source, thereby reducing the water pollution.
