Tony: Hey, Mark, maybe we could go swimming in the river later this afternoon.
Mark: I don’t think I want to go, Tony.
Tony: Why not?
Mark: I was there last weekend and the river was really dirty. Even the bottom of the river was full of rubbish, and there were no more fish for fishermen to catch.
Tony: No way! It used to be so clean. In fact, it has always been the nicest river in this town.
Mark: Not anymore. I think people are throwing litter into the river. Factories are also putting waste into the river.
Tony: That’s terrible! We should write to the government. They should close down the factories.
Mark: Good idea! But I think everyone in this town should help to clean up the river, too. Everyone should play a part, not just the government.

Susan: Yes, and I used to see the stars clearly.
Interviewer: What do you think has caused this problem?
Susan: Well, there are more cars on the road these days.
Jason: And factories that burn coal also pollute the air with a lot of black smoke.
Interviewer: What other problems do you see?
Susan: I guess there’s too much rubbish and waste in the streets.
Jason: Yes! Every day people are throwing away things like wooden chopsticks, plastic bowls and plastic bags.
Susan: They’re also littering in public places, for example, during picnics in parks. This is turning beautiful places into ugly ones.
Interviewer: You’re right. These are serious problems for our environment. Next, let’s talk about the things we can do to help.
