雅思口语part3: Do you think it is necessary to make environmental protection as a subject

你认为有必要将环境保护作为一个学科吗?

Yes, I believe so. Protecting the environment needs a lot of specialist knowledge. Take PM 2.5 for example, which has caused various problems in China. To alleviate the situation, we have to find out its causes and then make targeted solutions. This article is from Laokaoya website. Each stage needs experts who can be cultivated by studying the subject of environmental protection. The same is true in other environmental areas, such as waste disposal, global warming and the hole in the ozone layer.

是的，我认为如此。保护环境需要许多专业知识。以在中国引发许多问题的PM2.5为例。要缓解这一问题，我们需要找到它的原因，然后制定针对性的方案。每个阶段都需要专家。而这些人可以通过学习环境保护的学科培养出来。同样的道理也适用于其他环境领域，例如垃圾处理，全球变暖，以及臭氧层空洞。
