F: Welcome to our program. Today we have invited Fred Watson, an expert on the environment to talk to us. ,M: Hello, everybody. ,F: There are so many environmental problems in the world today. Mr. Watson, do you think we can really solve them all? ,M: I hope that world leaders can get together and agree on a plan for action. ,F: We need to solve the problem of air pollution. There's lots of clean modern technology that's out there. ,M: But many companies say it's too expensive. And developing countries pay more attention to industrial development than to environment protection. ,F: Everyone is looking at the problem in the short-term rather than the long-term. ,M: It's the same with the damage of the rainforests. Most companies just want the wood. ,F: They're not thinking about the long-term damage to the forests. ,M: No. In other parts of the world, especially in Africa, climate change and over-farming are causing farmland to turn into desert.
