Question

   It’s very important that we all recycle. In nature，everything 36     again. For example，when an animal dies,it becomes 37     animal’s food. Nothing is wasted. But humans have created things like plastic bags 38     can’t be broken down by nature. Our rubbish kills animals and 39     water and soil. 40     we continue making too much rubbish,the problem will only get worse. If nature can’t reuse the rubbish,we must recycle 41     We should clean up the rubbish we’ve made because nature can’t.

Recycling is also the right thing to do for another reason. The earth is rich in natural materials like water and trees,42     these materials are not endless. We use up our natural materials much 43      than the earth is able to reproduce them. For example,each year we cut 44     more than 6,000 square miles of forest. But it takes an average of 25 years for a new tree 45    

Recycling can help us save the earth,so let’s take action right now.
