Write a dialogue between two friends about the greenhouse effect.

Prity: Hello Mimi! How are you?

Mimi: I am fine. What about you?

Prity: I am fine too. What are you doing?

Mimi: I am reading an article on greenhouse effect.

Prity: Do you know that the world's temperature is undergoing a significant change? Mimi: Yes, I have come to learn it from the discussion of a TV channel.

Prity: Oh! It is alarming that the world's temperature is increasing day by day.   Mimi: You are right. This increase of temperature is called global warming.

Prity: But still now I do not know the cause of global warming. Do you know the cause of it?

Mimi: Yes, global warming is caused by the increased amounts of carbon dioxide

            around the earth. And the greenhouse effect is the most likely cause of global  

           warming.

Prity: What may be the effect of global warming?

Mimi: It may reduce mankind's ability to grow food, damage or destroy wildlife,

           raise sea levels, and thereby flood coastal areas.

Prity: I see it has many negative effects on mankind and animals.

Mimi: Exactly! So, all of us including the government should come forward to take

          immediate measures to get rid of these disasters.

Prity: You are right. We must save the world to save ourselves. Thank you.

Mimi: You are most welcome.
