问题 What can be done to reduce air pollution?
选项
答案 　　I think reducing air pollution takes a lot of work. Firstly, factories must filter the waste gas before emission. The waste gas has to reach the national standard before it’s allowed to be emitted into the open air. Unfortunately, many factories don’t follow laws and regulations. The government should strengthen the monitoring system Secondly, we should stop our reliance on fossil fuels, especially coal and increase the use of more environmentally friendly energy such as hydropower, shale gas and nuclear energy. The development of clean energy requires much work in fundamental research and its related applied technologies.
