(a) State three reasons to conserve water.

(b) State four ways in which you as an individual can conserve water.

(a) It is necessary for us to conserve water because —

1. The amount of water needed for all the living organisms is not available on earth in abundance.
2. In agriculture, water is needed in large quantities.
3. A large amount of water is required in industries.

(b) The ways by which we can conserve water are :

1. Wastage of water should be avoided, for example, taps should never be left open.
2. Do not allow water to drip from defective taps.
3. More plantations should be done as plants help in bringing rain.
4. We should use drip irrigation or spray-irrigation system for crops.
