[speaker001:] I think the biggest environment problem in my country is air pollution.
[speaker002:] Yes, I agree. The air here is much more polluted than in my country.
[speaker001:] That's because your country is more agricultural and has much less industry.
[speaker002:] Yeah, you are right.
[speaker001:] We have reduced emission of air pollutants in recent years, but cars are still a major source of them. Factories have become cleaner as stricter environment pollution laws have been introduced.
[speaker002:] The problem is now on a truly global scale. I don't believe that any single country can do anything about it.
[speaker001:] I think you're right. An international response to this problem is needed.
