    Waste can be seen everywhere and it can bring a lot of problems. China is rich in some resources(资源), we are short of other resources like fresh water. It is said we will have no coal(煤) or oil to use in 100 years. Also there is not enough food in some areas.So if we keep our resources, what can we use in future and where can we move? Think about it, I think we should say "no" to the people waste things every day.

    In our life, we can do many things to stop waste from happening. For example, remember to turn the lights when we leave the room and we'd better use both of paper. Also we should try not to order food than we need. Little by little, everything will be changed, waste can be stopped one day we do our best.
