Water Pollution

25. Water Pollution

We live in an environment. Our life is closely related to this environment. Today we are worried that this environment is polluted day by day. There are four types of pollution: air pollution, Water pollution, sound pollution and odour pollution. Of these four types of pollution, water pollution is very serious. We know that water is life and this water is polluted in many ways. Farmers use chemical fertilizers and insecticides in their fields. The rain and floods wash away some of these chemicals. They get mixed with canal water and river water. Mills and factories pollute water by throwing waste materials into the rivers. Steamers, launches and other water vehicles pollute water by throwing oil, food waste and human waste into the rivers. Insanitary latrines and unsafe drains on the riverbanks also pollute water. Water pollution causes water-borne (পানিবাহিত) diseases such as cholera and diarrhoea. Besides, it creates a serious health hazard (স্বাস্থ্য সমস্যা). We know that every year millions of people all over the world die as a result of water pollution. To prevent these unfortunate and avoidable deaths, we have to prevent water pollution.
