A; is the environment a big issues in your country? It is in mine.
B: it is in mine too. The biggest issue is water. The climate is dry and so water conservation is very important.
A: what methods do you use to conserve water?
B: water is rationed. We can only use a certain amount each month. It means that we cannot use some modern household items, like washing machines. They use too much water.
A: I see. I think the biggest environment problem in my country is air pollution.
B: yes, I agree. The air here is much more polluted than in my country. Of course, my country is more agricultural and has much less industry.
A: 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 law have been introduced.
B: the problem is now on a truly global scale. I don't believe that any single country can do anything about it.
A: I think you're right. There needs to be an international response to this problem.
