Dialogue on air pollution

Sujon	Hello Farjana! How are you?
Farjana	I am fine. What about you?
Sujon	I am fine too. But I am little worried about air pollution.
Farjana	Oh, I see. Nowadays it has become a great problem which is creating a constant threat to our life
Sujon	Exactly! Air is being polluted in many ways though it is called life-giving force.
Farjana	Absolutely! The most common agent that pollutes air is smoke.
Sujon	Yes, smoke pollutes air. Moreover, railway engines, bus, trucks, also use petrol and diesel oil. All these things create smoke and cause air pollution.
Farjana	You are right. Smoke of all kinds produces carbon monoxide and carbon dioxide and thus pollute air.
Sujon	You might have noticed that the most serious air pollution occurs in big industrial areas where there are many big mills and factories.
Farjana	Yes. Besides, it occurs in big cities where many buses, trucks and cars move on the roads every day.
Sujon	Deforestation also plays an important role in air pollution by increasing CO2 in the atmosphere.
Farjana	You are right. And due to air pollution, our environment is getting warm and losing its balance.
Sujon	Exactly! Besides, polluted air is causing different incurable diseases to human beings.
Farjana	But we must take steps to reduce air pollution. To ensure a healthier and happier life, there is no alternative to keep air free from pollution.
Sujon	Of course. We all should be aware and protect our air from further pollution. Thank you.
Farjana	You are most welcome. Bye and see you again.
