第二次翻譯 1-4第7段

翻譯:
淨化常常清除環境中部份的汙染物，卻反而造成另一種形式的污染。例如，我們把垃圾收集起來，但是那些被收集起來的垃圾後來被燒掉(也許造成空氣污染，留下被放置某些地方的有毒灰燼)，隨意四處傾倒在土地上 (也許造成水的汙染)，或掩埋(造成土壤跟地下水污染)。

原文:
Second，cleanup often removes apollution from one part of the environment only to cause pollution in another.For example，we can collect garbage，but the garbage is then burned (perhapes causing air pollution and leaving toxic ash that must be put somewhere )，durmped on the land ( perhapes causing water pollution through runoffor seepage into groundwater)， or buried(perhapes causing soil andgroundwater pollution).
