3. Work in pairs. Talk about the other human activities that contribute to global warming. Use the ideas in 1, the model and the tips in 2 to help you.
(Làm việc theo cặp. Nói về các hoạt động khác của con người góp phần vào sự nóng lên toàn cầu. Sử dụng ý tưởng trong phần 1, mô hình và mẹo trong phần 2 để giúp bạn)
Bài Làm:
Sophie: Hey John, have you heard about the different human activities that contribute to global warming?
John: Yeah, I have heard about some of them, like cutting down forests and burning fossil fuels.
Sophie: That’s right. Cutting down or burning forests releases carbon dioxide, but burning coal, oil, and gas also contribute to global warming. When fossil fuels are burnt, they release greenhouse gases that trap heat in the atmosphere.
John: That’s really interesting. I didn’t know that. Are there any other human activities that contribute to global warming?
Sophie: Yes, there are. For example, raising farm animals like goats, sheep, and cows also contributes to global warming. These animals produce a lot of methane, which is responsible for nearly one-third of current global warming.
John: Wow, I had no idea that raising farm animals had such a big impact on the environment. What about the impact of cutting down forests for farming?
Sophie: That’s a good point. Cutting down forests to make space for farm animals also contributes to global warming. Forests store carbon in the trees and soil, and help reduce the global temperature. When forests are cut down, the carbon is released into the atmosphere, which contributes to global warming.
John: Thanks for sharing all this information with me, Sophie. It’s really eye-opening to learn about the different human activities that contribute to global warming.
