Nowadays many people get used to wasting things，especially young people. In the school，waste can be seen1. Some students ask for more2than they can eat and others often forget to3the lights before they leave the classroom.
Waste can bring a lot of problems. Someone says China is4in some resources，such as coal，oil，trees and so on. Some people even say"How rich our country is!"But actually we will have no coal or oil to5in 100 years if we go on wasting. We really feel6about what we can use in the future. We can't imagine how we can go on living without these resources. Think about it7. I think we should say "no" to the8who waste things every day.
In our daily life，we can do things to stop waste from happening. For example, we should tun off taps9using them. Don't throw the used paper because we can recycle it. Let's start out small from now on.
Little by little，everything will be changed. Waste can be stopped one day if we do10best. The nature will be more harmonious（和谐的）and our country will become more and more beautiful.
