Waste can be seen everywhere in the school. Some students ask fo r more food than they can eat and others oft en forget to turn off the lights when they leave the classroom. They say they can afford these things. But I don‘t agree with them.
Waste can bring a lot of problems. Although China is rich in some resources(资源), we are short of(缺乏) others, for example, fresh water(淡水)。 It is reported that we will have no coal(煤) or oil to use in 100 years. So if we go on wasting our resources, what can we use in the future and where can we move? Think about it. I think we should say no to the students who waste things every day. Everybody should stop wasting as soon as possible.
