Answer: Pollution is the process of making the element of environment dirty. The elements of environment such as water, air, soil etc are getting polluted every day. Of all the pollutions, water pollution is the most threatening to our life. Water, a vital element of the environment, is also polluted in different ways. Man pollutes water by throwing waste into it. Farmers use chemical fertilizers and insecticides in their fields. When rain and floods wash away some of these chemicals get mixed with water in rivers, canals and ponds. Mills and factories also throw their poisonous chemicals and waste products into rivers and canals and thus pollute the water. Water vehicles also pollute rivers by dumping oil, food waste and human waste into them. Insanitary latrines and unsafe drains standing on river and canal banks are also responsible for further pollution. Furthermore, Kutcha drains running into the canals and rivers cause water pollution. Clean water is safe for use but polluted water is harmful for man. Water pollution can be prevented in many ways. We suffer from cholera, diarrhoea, dysentery and many other water-borne diseases when we drink polluted water. We should refrain from throwing waste and filth into water to minimize water pollution. However, it is important to note that water is life, but polluted water causes death.
