Our city sets up a project about environmental protection three years ago. Many people have been taken part in it since it was run. It is obvious what people's awareness of environ- mental protection are increasing. Some people think factory owners have much responsibility for preserve the environment. Environmentalists have made many statement to support their own opinions so far.Some factory owners focus on enlarging production in order to make a largely amount of money.
