Nobody could have failed to notice the fact that wasting has become a grave problem in many campuses. In the dining hall, much food are left in the plates and dumped into the trash can. In the classroom, blank or half blank pieces of paper are left on the desks. In the dorm building, taps are left open and water left running or dripping all the time. And there can be more such examples.
In view of the expanding population and the shortage of various resources, wasting is really a harmful habit. It put strains on the already short supply of food, water, electricity and the like. Besides, it goes against traditional virtue of hard work and simple living and may leads to a luxurious life style, which is dangerous to the souls of mankind.
Therefore, it is high time that we take steps to stop wasting. We should start from trifles around ourselves: remember to turn off the tap when we finish washing; try to order the exact amount of food we can consume; never throw away any blank or half blank pieces of paper. And always remember, a penny saved is a penny earned.
