Tony: So, tell me. Why is it important to save the rainforests?
Leila: There are many reasons. One is that a number of plants which could be useful grow in the rainforest. We don't know all the plants yet - there are thousands and thousands of them. Researchers are trying to discover their secrets before they are destroyed.
Tony: I see. What other reasons are there?
Leila: Well, I'm sure you heard of global warming.
Tony: You mean the idea that the world is getting warmer?
Leila: That's right. The rainforests have an important effect on the earth's climate. They are disappearing at a terrifying rate and soon they will be gone. People are not doing enough to save them.
Tony: But is global warming really such a problem? I enjoy warm sunshine.
Leila: Well, what happens when you heat ice?
Tony: It melts of course.
Leila: OK. the polar ice caps consist of millions of tons of ice. If they melt, the level of the sea will rise and cause terrible floods. Many scientists believe that temperatures are already rising. We must do everything we can to prevent global warming, and that includes preserving the rainforests!
Tony: Thank you, Leila, and good luck for your campaign.
