It is also in my heart. The biggest problem is water. The climate is dry, so saving water is very important.

How do you save water?

Water is rationed. We can only use a certain amount every month. This means that we can't use some modern household items, such as washing machines. They use too much water.

I see. I think the biggest environmental problem in China is air pollution.

Yes, I agree. The air here is much more polluted than in my country. Of course, my country is more agricultural and much less industrial.

A: In recent years, we have reduced the emission of air pollutants, but cars are still the main source of air pollutants. With the implementation of stricter environmental pollution laws, factories have become cleaner.

B: This problem is really global now. I don't believe any country can do anything about it.

I think you're right. An international response is needed to this problem.

There are so many environmental problems in the world today. Do you think we can really solve it all or destroy the world?

b； I hope world leaders can get together and agree on an action plan, but I doubt whether this will happen, otherwise it will be too late.

a； We need to solve the problem of air pollution before destroying the atmosphere. There are many clean modern technologies, but companies in developed countries say it is expensive. Developing countries pay more attention to economic development than environmental protection.

B: Everyone looks at this problem in the short term, not in the long term. So is the destruction of the rainforest. Countries and companies just want wood. They didn't consider the long-term damage to the forest. We should also remember that forests are important natural habitats for thousands of plants and animals.

a； Desertification exists in other parts of the world, especially in Africa. Climate change and over-cultivation are causing farmland to become desert. This means people can't grow enough food.

This also means that people sometimes fight for the remaining farmland. Destroying the environment will actually lead to conflicts between people.

Have you ever thought about joining an organization dedicated to protecting the environment? You can take part in projects to improve the environment.

I think I'd like to do that. When I finish my studies, I can take what I have learned here back to China.

Bonnie: We will do some research on the pollution of the Pearl River. Do you have any thoughts about this?

Jason: Since pollution is one of the biggest problems in the world, I believe many people are interested in this topic.

Sarah: Polluted water is very harmful to people's health, so I think our work is very meaningful.

Bonnie: We can also visit some factories along the river.

Jason: Good idea, because factories always pour waste water directly into rivers, which pollutes the environment.

Bonnie: We can also borrow some books on this subject.

Jason and Sarah: OK. Let's go to the library now.
