Nam: Hello Mai. Long time no see. How are you?

Mai: Thanks, Nam. I am fine. What’s about you?

Nam: I’m good. Where are you going?

Mai: I am writing to the local authorities to request him to take necessary measures which alleviate environment pollution.

Nam: That’s a good idea. We need to join hands to deal with this worldwide problem!

Mai: I couldn’t agree more. 

Nam: People are not aware of it. They drop litter everywhere. 

Mai: Also, smoke coming from industrial factories is polluting the environment seriously.

Nam: Too many vehicles are polluting the air by exhaust emissions.

Mai: Oil spills also contribute to making the world polluted.
Nam: So, what should we do?

Mai: We should take care of our environment. It’s true that we cannot prevent pollution completely. But we can lessen it.

Nam: I absolutely agree with you. I’ve got to go, Mai. See you next time.

Mai: Bye.
