问题 What are some of the most important environmental challenges facing your country?
选项
答案 　　China is a very huge country, so different regions face different environmental challenges. One of the most important issues in recent years is smog. Many big cities in China, especially those in the north of China, have experienced severe smog. The level of PM2.5 has even reached an astonishing 300 in many cities such as Beijing and Tianjin. This means that it’s extremely bad for people to breathe in such air. In the south of China, smog isn’t that severe. Deforestation is one of the most serious environmental issues facing cities in this region. Deforestation further causes problems such as floods, droughts and acid rain.
