Read the text and answer the questions 1, 2, 3, 4 and 5.
Air is an important element of our environment. Clean air is essential for life. But air can be polluted in many ways. One thing that pollutes air is smoke. By inhaling polluted air we become sick. Man makes fire to cook his food. We use fire to make bricks and to burn refuse. In order to melt pitch for road construction we make fires. By burning wood and melting pitch people create more smoke. Railway engines and power houses use coal and oil. Coal and oil create smoke when they burn. Mills and factories use not only coal and oil, but also many chemicals. Buses, trucks and cars use petrol and diesel. Their engines burn these things to make energy. All kinds of smoke pollute the air. But the most serious air pollution occurs most often in big industrial areas where there are many mills and factories. By preventing air polluting we can be healthier and happier.

At first take my cordial love. Hope you are hale and hearty. In your last letter you wanted to know about air pollution of Dhaka. Now I am telling you about that. There are 15 million people in Dhaka. For excessive population there are lots of vehicles and industries. They make smokes. I think vehicular and industrial exhaust is the major problem in Dhaka. For smoke people suffer from airborne diseases.
What ever happens we have to protect our environment with the government? So every one of us should plant trees more.
That’s all for today. What do you think about water pollution? Write soon.
Your loving friend,
