Waste can be seen everywhere and it can bring a lot of problems. China is rich in some resources(资源), but we are short others, for example, fresh water. It is said we will have no coal or oil to use in 100 years. Also there is not enough food in some areas. So if we keep (waste) 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 (day) life, we can do many things to stop waste from (happen). For example, remember to turn off the lights when we leave the room and we'd better use both (side) of paper. Also we should try not to order (much) food than we need and on. Little by little, everything will be changed, and waste can (stop) one day if we do our best.
