Most of our water bodies— rivers, lakes, seas, oceans, estuaries and underground water sources are gradually becoming polluted. In the course "Covered so far, you have seen how deforestation, urbanization, intensive agriculture and industrialization have caused pollution of water bodies.

My neighborhood is facing with 3 types of pollution. The water pollution is the most serious problem, then the noise pollution and the last is visual pollution. Water pollution affects our whole life. There is not enough clean water to drink, and to use for daily activities. The factory near by has released a lot of chemicals, which kill fish and make the water unusable. We might also catch diseases, especially cancer. Noise pollution is caused by too many traffic. They always work the car’s hooters. And visual pollution is caused by too many telephone poles, advertising billboards, overhead power lines.
