(i) How do men pollute water? (ii) How to farmer pollute water? (iii) How to mills and factories pollute water? (iv) What are other ways of water pollution? (V) How can we minimize water pollution?
Water an important element of the human environment is essential for human and plant life. It is next air. Water can be polluted in many ways. First of all, farmers use chemical fertilizers and insecticide in their fields to grow more food. The rain and floods wash away some of the chemicals, they get mixed with the river water, canal water, and pond water, secondly, mills and factories pollute water by throwing the waste materials and unsold products into the rivers and canals. Thirdly steamers motor launches and even sailboats can pollute water by throwing oil, food, waste and human waste into the rivers and canals. Moreover, unsanitary latrines in the countryside standing on the banks of the rivers and canals also pollute water. Besides the Kutcha drains running into the rivers and canals cause water pollution, clean water is safe for the use and polluted water is harmful to man. Water pollution can be prevented in many ways. First of all, we should make the people aware of the fact that water next to air. It is called life. So, fertilizer, chemical, and pesticide should not be allowed to mix the river water, canal water, and pond water. Mills and factories should not throw the waste materials and unsold products into river and canals. Steamers, motor launches, and even sailboats should not throw oil, food waste and human waste into the river and canals. Unsanitary latrines in the countryside should not be built on the banks of the river and canals. In fine awareness should be created to the public.
