Water is used not only for drinking purposes but also for household works, agriculture and industrial works. Water is polluted in many ways. Human beings are mostly responsible for it. Man pollutes water by throwing waste into it and making unsanitary latrines by the banks of rivers or canals. Farmers use chemical fertilizers and insecticides in their fields. These are washed away by flood or rain water and pollute the nearby rivers, canal or pond water. Mills and factories throw their wastes and poisonous chemicals into rivers and pollute the water. Steamers, launches and even sail boats can pollute water by throwing oil food waste and human waste into the rivers and canals. By drinking polluted water, we become ill. Cholera typhoid, dysentery and other water-borne diseases attack us if we drink polluted water. Fishes die, even farming becomes impossible in severely polluted water. We can prevent water pollution by careful waste management. Farmers should use organic fertilizer instead of chemical fertilizer. Sanitary latrines should be used. Above all common people should be conscious of it.
