Writing prompt: Create a Green Campus

Student essay:
Nowadays, many big cities have serious environmental problems, for example, that the air is not fresh and that the pollution is more and more serious. The reasons are that the cars and the factories emission the gas and there are too many forests cut. So when a person inhales the harmful thing, it not only causes the disease like lung cancer but also does harm to health. I suggest that the government control the number of the cars and stop the factories from polluting the river as well as the air. What's more, I think that we should go out on foot or by bus.
