  Human and Nature 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。
