carbondale

Different cities have different features. I was living in an industrial city, which is big but polluted. The air pollution is the most serious problem. People could not breathe clean air unless they woke up early in the morning and went to parks which are full of tress and grasslands. Certainly, usually we cannot see animals in the city except in wildlife refuges which are built by the government to protect them. One reason for this problem is that factories release polluted air or chemical air into the sky; also the air from the car makes the problem worse. The government could not control the industrial air release completely, so they have began to invent new resources, which are harmless to environment. However, Carbondale is a nice city, for the air is clean all the time. Also I can see some animals everywhere, such as squirrels and deer.
