There used to be many kinds of birds which are pests for protected crops. They are good friends at present.But the number of the birds has been greatly reduced because too much poison is used. As the result, the numberof the pests has increased.The peasants spent a lot of money and time in killing them every year.But it is still hard to eliminate them.Now you can see how poor it is for us to protect wild animals and to keep the balance of nature.Only that everyone know these can we live on a beautiful lives.
曾经有许多鸟类都能够保护庄家，以防害虫的侵害。他们是农民的好朋友。但是鸟类的数量正在急剧减少，这是因为人们大量使用农药造成的。所以，害虫的数量增加了。每年，农民都会花费大量经费，以及时间来消除害虫。但是，人们还是很难将它们清除。如今，我们无法保护野生动物，并无法保持生态平衡。只有我们所有人提高意识我们才能过上幸福的生活。
