Water is an important element in our environment. No creature can live without it. It is essential for life. But polluted water is harmful to it. Water is polluted in many ways. Our farmers use chemical fertilizers in their fields to grow and get better crops. They use insecticides to kill the harmful insects that damage their crops. These are sometimes washed away into the rivers, canalsand ponds and get mixed with water and pollute it. Sometimes, mills and factories throw their waste products
containing poisonous chemicals into rivers and canals and pollute water. Again, launches and steamers and even sailboats pollute water by throwing burnt oil, food waste and human waste into the rivers. Often human waste and filth from the in sanitary latrines and kutchha drains run into the rivers and canals and ponds and thus pollute water. Polluted water causes various kinds of diseases and sometimes causes death. So, we must prevent the pollution of water in order to live a healthier and happier life.
