Suppose, you are Tanvir/Tanisa. You have a friend named Habib/Habiba who has breathing problem. Now, write a dialogue between you and your friend about air pollution.

Habiba:Hello, Tanisha. How are you?

Tanisha: I'm fine, thanks and you?

Habiba : I'm not so fine. I'm suffering from breathing difficulty.

Tanisha: Why? I found you well yesterday.

Habiba : Actually I'm coming from Uttara by bus. The smoke, dust of construction work have made it tough for me to breathe.

Tanisha : Air pollution! This is really a big problem for our country.

Habiba : What's the main cause of air pollution?

Tanisha : Smoke is the main cause.

Habiba: Can you explain how smoke is created?

Tanisha : Smoke is created in various ways.

Habiba : Like what?

Tanisha : People make fire to cook food, melt pitch for road construction, which generates smoke. Also, buses, trucks, and cars use petrol and diesel, which also create smoke.

Habiba : How is air pollution harmful to us?

Tanisha : When we inhale polluted air, we become sick. It's a serious threat to our health.

Habiba : How dangerous! Nowadays I have been facing breathing problem. The doctor has suggested me to use mask as the polluted air causes more trouble for me.

Tanisha : Oh, that's really sad! Please follow the doctor's instruction.

Habiba: Yes, I-am trying my best. Thank you.

Tanisha: & See you around, Habiba .
