Nature, the environment which human beings live by, is magnificent and unique. There si only one earth with super living conditions in the universe. We should have cherished nature and preserved it. Conversely, however, we have been continually spoiling it, even to a shocking degree. Now let's see what we have dong. Thousands of trees have been cut down per year, which has caused soil erosion. Hundreds of thousands of tons of CFCS have been left in the higher sky in the last decade which has led to the ozone layer leak above the South Pole that covers an area of that of the United States. Million tons of fuel containing nitrogen and sulphur have been consumed per year, which has eventually resulted in acid rain throughout the world.Similarly, ecology has been affected as well. And considerable number of species have been extinct as the years go by many creatures which were common in the past are becoming less and less, even rare. The Tibet antelope, for instance, is a good example. Since the antelopes of Tibet have a part of fur on their body which can be made into a precious cape, driven by some lawless dealers many villagers killed antelopes excessively and shocking for the large suns of fortune. Because of this, the number of the antelopes of Tibet has sharply fallen from over one million to less than one hundred thousand. And what's more, the number has now decreased by 20 thousand per year.Qing Zang Platean, which was their homeland, is their tombs now. This is how nature has suffered what we have done to it. However, nature and suffer any more. She lost her temper and could no longer possibly put up with humans. She gave humans harsh punishment, which she thought they deserved. The acid rain has caused the less of more than 100 billion dollars throughout the world per year. And because of desertisation, soil is becoming more and more barren. The soil of many planes is now until for growing plants. The air is less fresh, and a lot of people even get many stranger diseases.Those are all the punishment of nature to human's pollution. On the other hand, human being suffer a lot as well. So it leads to a serious of questions-- Why can't we live harmoniously with nature? Why can't we set a balance between human and nature? Why can't we pay more attention to nature and try to reserve it? Therefore, before we take immediate measures to do something, we should be aware of the fact that "Conquering the nature" will never be our goal, instead, we should take the nature as our intimate friend. Preserving nature is not only preserving our home, but the civilization of human community as well.
