Garbage disposal is a major problem in
    most cities around the world. Finding places
    for garbage is getting more and more difficult.
    Recycling is, therefore, becoming very popu-
    lar. In other words, more and more people
    are treating used material so that it can be
    reused. There is no doubt that recycling
    helps save our precious natural resources. It
    is in our own best interest to recycle.
    資源回收再利用
    垃圾處理在世界各地的大部分城市里是個大問題。尋找垃圾
    處理場越來越困難了。因此，資源回收變得很普遍。換言之，越
    來越多人在處理使用過的東西以便重新加以利用。毫無疑問，資
    源回收有助于節(jié)省珍貴的自然資源。資源回收對我們是最有利
    的。
