PART ONE    WRITING

Creating a green campus

It is of great importance to make and maintain a green campus in our university or college. Obviously, a growing number of people are beginning to realize that it is our duty to do that in the present days, since the concept of “a green world” has become the focus of the society.

The idea of “a green campus” is beyond a green environment. To begin with, the development on the campus is to be sustainable and recyclable. Some of the authorities’ budget should be on how to reduce of the waste. What’s more, we’d better be aware of the seriousness of pollution around us. Thus the idea of environmental protection may become a common occurrence in our daily life.

It is necessary that effective actions should be taken to protect our campus from waste and pollution, and hence these activities are to play an increasingly important role in our day-to-day life. Certainly, there is little doubt that further consideration must be paid to our green campuses.
