as is known to all, waste on campus has become a more and more serious problem.
now, our life is richer, but we shouldn't waste on campus, because the parents work hard to earn money to let us go to school. so we can't waste on campus.
it's easy to reduce waste on campus. first, don't buy something that we needn't. then, when we have a meal, we shouln't waste food. finally, we must reduce waste water and paper.
don't waste anything! many people are in urgent need of the basic things that we throw away every day. so don't waste please.
