Now a days environment pollution is one of the most talked of topics in the world.Our environment is polluted in two ways.One is air pollution and other is water pollution.We pollutes air by factories smoke,melts pitch for road construction and burns wood.All this things produce heavy smoke and this smoke pollutes air.On the other hand for our fault we pollute water.Mills and factories pollute water by throwing the waste materials and unsold products.Unsanitary latrines in the countryside standing on the banks of the rivers and canals also pollute water.So,all this things pollute air and water badly.
