Although the works will make a lot of money for our city, we do think it will do us more harm than good. The drinking water will be badly polluted. Of course, they have promised to do something to prevent the water from being polluted, however, it is far from enough. On the other hand, the air over the city will be polluted too .We will never be able to breathe fresh air. How can we live here any longer? Last but not the least, the site of the chemical works has been the only place where we students play games and have sports after school. Where would we go if it were occupied?
