Polluted water is very harmful for health. By drinking impure water, many people often suffer from many diseases like typhoid, malaria, cancer etc. Polluted water also destroys fish and plants by decreasing the amount of oxygen in the water bodies.

Therefore, proper measures should be taken to prevent water pollution. Disposal of human and industrial wastes in ponds and rivers should be avoided. The use of pesticides in agriculture should be reduced. More plants and trees should be planted to prevent pesticides and fertilizers from running into nearby water sources.
As we already know that without water no life can survive. Therefore, we must keep the water clean. If everyone follows their responsibility to protect water from getting polluted then it will be easy to get clean and healthy drinking water.
