　　In recent years, extravagance and waste have become increasingly serious in some of the university campus. We can see that papers, bottles and cans are thrown away after use; food is wasted just because of its poor taste; clothes are discarded simply owing to their old fashion. As a consequence, people in mounting numbers put great emphasis on creating a green campus.

　　There are at least two criteria to distinguish what is green campus. On the one hand, natural resources must be conserved and made full use of, for example, we, as college students, should take the wise use of papers and second-hand textbooks into account. On the other hand, education to build up thrift habits must be promoted by relevant departments and professionals at various levels.

　　Accordingly, it is necessary for us to take effective steps. For one thing, university authorities should respond with the demand for more rigid conservation of our natural resources, such as water, electricity, and so on. For another, we should enhance the awareness of college students that creating a green campus is of utmost significance to both our society and ourselves.
