Is water conservation necessary? Give reasons.
Conservation of water is necessary due to following reasons:
(i) Uneven distribution: Some parts of our country have high resources of water whereas other parts suffer from chronic water shortage. This causes floods in some regions and drought in other regions.
(ii) Fluctuation in rainfalls is very common and wide seasonal rains are observed yearly.
(iii) Dumping of untreated sewage and industrial wastes in rivers and ponds make them polluted.
(iv) The changing lifestyle of people increases the consumption of water, especially in urban areas.
(v) High yielding varieties of crop uses much more water for irrigation.
