Answer: Pollution means contamination of the environment. Our environment is polluted in two ways pollution and water pollution. Air is polluted in many ways. Smoke pollutes the air. Man makes fire to cook his food, makes bricks, melts pitch for road construction, and burns wood. All these things produce heavy smoke and this smoke pollutes the air. Railway engines, mills factories, and powerhouses use coal and oil. Buses, trucks, and cars use petrol and diesel. Again all these things cause air pollution. Water is polluted in many ways. Farmers use chemical fertilizers and insecticides in their lands to grow more food. The rain and floods wash away some of the chemicals. They get mixed with canal water and river water. Mills and factories pollute water by throwing waste materials and unsold products into the rivers and canals. Steamers, launches, and even sailboats pollute water by throwing oil, food, and human waste into the big canals and rivers. Unsanitary latrines in the countryside standing on the banks of the rivers and canals also pollute water. Thus air and water are polluted and as a result, our environment gets polluted.
