Tape script:
Int: David, what do you see as the main problems with the environment?
D.U: Well, in a nutshell, the most urgent problem of all is the climate. The world’s climate seems to be getting warmer.
Int: We’ve seen a lot of evidence of that, haven’t we? Hotter summers, warmer winters, that kind of thing.
D.U: Yes, we have. Also, scientists have found that the ice at the Poles is beginning to melt.
Int: We have heard that too. Is that really happening?
D.U: Yes, I’m afraid it is. And at sometime in the future, the ice may melt completely. Then it’s possible that the sea could rise and coastal cities like New York and Shanghai could disappear under water.

Int: It sounds very frightening.
D.U: I couldn’t agree with you more. It’s scary!
Int: Can you explain why the climate’s getting warmer?
D.U: Well, I’ll do my best! It’s pollution that’s the problem.
Gases from cars enter the atmosphere and stop the sun’s heat from leaving the atmosphere. And factories give out chemicals that do the same thing. So as a result, the climate’s getting warmer.
Int: From what I understand, carbon dioxide from cars is a major problem.
D.U: You are absolutely right. Carbon dioxide is the gas that does most damage to the atmosphere. But we have a problem with trees too. You see, trees give out oxygen and take in carbon dioxide. So they’re very useful because they use up the carbon dioxide.
Int: I know what you’re going to say. We’re cutting down all the trees.
D.U: Yes, we cut them down because we need the land and because we use the wood for paper and furniture. That leaves more carbon dioxide in the atmosphere.
Int: It’s a terrible situation.
D.U: Yes, and another problem is all the garbage that we produce. We burn a lot of garbage, and once again, the gases pollute the atmosphere. The situation couldn’t be worse, really.
Int: We should recycle garbage, not burn it.
D.U: Of course we should.
Int: It’s strange, we know all this, and yet we do nothing but talk about it. I can’t help but feel very concerned.
D.U: Yes, well, it is worrying. But governments are beginning to do something about it. I don’t think it’s too late.
