MODEL2 Rainforests will soon be only a memory.
Script
Susan: Hey, Chris, there is an environmental group on campus asking for donations to save the rainforests.
Chris: So what?
Susan: So what?! Don’t you want to save the rainforests?
Chris: But there’re no rainforests in our country. They need hot, tropical climates.
Susan: Come on. A rain forest is any forest where heavy rainfall leads to dense¹ vegetation. Tropical rainforests can be found in hoe, tropical areas, but there are also cool rainforests, including one in southeast Alaska.
Chris: How did you know that?
Susan: Well, I’ve just read a book on rainforests. You know, 140nillion people live in the world’s rainforests, and 35 percent of the world’s plant and animal species exist only in rainforests.
Chris: Wow, I’m impressed. So what else have you learned?
Susan: Most of the world’s rainforests are in danger of destruction by loggers, farmers and developers. They are disappearing at a rate of 1000 acres a minute!
Chris: It’s terrible!
Susan: Yeah, we’ve got to find a way to save them. Now would you like to give a donation?
Chris: Sure.
