HOW THE ENVIRONMENT IS POLLUTED

The world is producing millions of tons of tons of domestic rubbish and toxic industrial waste each year, and it is becoming increasingly difficult to find suitable locations to get rid of all the refuse. The disposal of various kinds of waste is seriously polluting the environment. We know that air is an important element of our environment and our air is polluted by smoke. Man makes fires to cook food, make bricks, melt tar for road construction and to do many other things. fires create smoke and pollute the air. Railway engines and powerhouses create smoke by burning coal and oil. Mills and factories also belch a lot of smoke. Buses, trucks, and cars use petrol and diesel oil. These too emit smoke. All these kinds of smoke pollute the air.
