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.
