Application of garbage

Our life is full of rubbish.If we discard it, then we will waste these resources.And we will destroy the ecology of the whole earth.

So we must use it.

Like some artist，they will use the rubbish and make it to be some beautiful works.

So I think，we can make it too.

In fact, we don't need to make it look good. But if we think about to do it， It will be the best.

But now it has a problem too，how to handle superfluous（多余的） rubbish？ Because we can use the more rubbish but we can't use all of them.
