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 (TRY) 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 (GET) warmer?
Leila	That's right. The rainforests (HAVE) an important effect on the earth's climate. They (DISAPPEAR) at a terrifying rate and soon they will be gone. People (NOT DO) enough to save them.
Tony	But is global warming really such a problem ? I (ENJOY) warm sunshine.
Leila	Well, what (HAPPEN) when you (HEAT) ice?
Tony	It melts (MELT) 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 (ALREADY RISE). We must do everything we can to prevent global warming, and that (INCLUDE) preserving the rainforests!
Tony	Thank you, Leila and good luck for your campaign.
