     Why do we need to throw less away? There are two reasons. One is that some resources (资源）are nonrenewable (不可再生的）.That means there is only a certain amount of that resource in the world. One example of this is oil. When we use up all the oil in the world, there will be no more.

    There is another reason for throwing less away. All of our trash has to be put somewhere. Often, it is put into garbage dumps (垃圾场）. Much of that trash will be there for hundreds of years. The dumps will be filled up with all this trash.

    There are three ways to cut down on trash.

    One way is to recycle. When you recycle something, it means it is made into another shape and used again. Old newspaper may become paper bags. A glass jar can be melted (溶化）and made into a bottle.

    Another way to cut down on trash is to reuse things. You can wash and use again a bottle that can hold relish or something else.

    The third way to cut down on trash is to reduce the    amount    of trash    you make, stop buying things    that you don ’t  need in the first place. Then reduce    the amount  of the earth, s trash.
