We need to protect wild animals, because we protect wild animals, wild animals will be very friendly to us.

　　Like the swallow, swallow can help us to eat the pests in the field. If we human beings killed to catch them, they will eat mosquitoes that often to scratch faze us, let us better life? Without the swallow around us become many insect pests, these pests have great harm to our human!

　　I have an example. For example the frog, the frog can also help us to eat the pests in the field, can be said to be the police in the field. Once we kill them, not the frog, the pests in the field more and more, pest constantly eat vegetables, don't we will have a good harvest?

　　I have an example. Such as w, w is a doctor in the forest, it can help us to eat the pests in the tree, the tree back to health. We killed them, pests will be more and more trees, trees will slowly decrease. No trees on earth, floods, earthquakes.

　　My last an example. Such as owls, catch rats, the owl is good for us human beings, human is often hunt them. No owls, voles will increase. Rats ate the crops and vegetables is more, we human beings did not have a good harvest.

　　So, we need to protect more than animals. At the same time, we also need to protect other wild animals!

　　我們要保護野生動物，因為我們保護野生動物，野生動物對我們人類也會很友好。

　　比如說燕子，燕子能幫我們把田里的害蟲吃掉。如果我們人類殺害捕捉它們，它們會吃掉那些常常來搔擾我們的蚊子，讓我們更好地生活嗎?沒有了燕子，我們的周圍變得很多害蟲，這些害蟲對我們人類有很大的壞處呀!

　　我還舉個例子。比如說青蛙，青蛙也能幫我們吃田里的害蟲，可以說是田里的警察。我們支捕殺他們，一旦沒有了青蛙，田里的害蟲越來越多，害蟲不斷地吃菜，難道我們會有美好的豐收嗎?

　　我還舉個例子。比如說啄木鳥，啄木鳥是森林中的醫(yī)生，它可以幫我們吃掉樹里的害蟲，讓樹恢復健康。我們殺害它們，樹木的害蟲會越來越多，樹木會慢慢地減少。地球上沒有樹，會發(fā)洪水、地震。

　　我最后舉個例子。比如說貓頭鷹，貓頭鷹捉田鼠，是對我們人類有好處的，人類卻常常捕獵它們。沒有貓頭鷹，田鼠會增加。田鼠吃的莊稼和菜就更多了，我們人類一樣沒有好的收成。

　　所以，我們要保護以上的動物。同時，我們還要保護其他的野生動物!
