Radio host: Our next caller is Tammy. Tammy, you’re on the air.

Tammy: I live near an underground station. This morning, the ground outside the station was clean. But in the afternoon, some people started giving out advertisements outside the station. Many people threw these advertisements on the ground. Now the road is full of litter. What can we do?

Radio host: Well, you can go out with your friends and help pick up the litter. You can also ask the workers at the underground station to put up a sign saying,“Do not litter.”

Tammy: Thanks. That sounds great.

Radio host: I’m glad to help. Now we have Louise. How can we help you, Louise?

Louise: My family has a lot of problems with noise pollution. First, our neighbour plays the drums and we cannot sleep at night! Next is the awful noise from cars. That goes on all day. Finally, next year, there’ll be a building site nearby. It’ll be noisy. What can we do?

Radio host: Well, when you have a noisy neighbour, you need to talk to the building manager. As for the cars and building site, you can contact the city government and see if that helps.
