Lesson from the nature
Today,too many trees are still being cut down in many countries and floods all over the world are getting more and more serious.A lot of land has gone with them.This is lesson from the nature.
When people move into a new place,they often cut down trees or pull out many wild plants to make farmland.Maybe they don’t think they can eat trees or grass.They don’t know very much that trees can stop floods and the wind from washing or blowing the earth away,and that many of these wild plants are food for some wild animals.If the animals cannot find enough plants to eat,they will die or have to leave the place.
In one part of the United States,for example,the deer there like to eat a kind of wild flower.The mountain tigers there eat the deer.But people killed many mountain tigers to protect the deer.Soon there were so many deer that they ate up all the wild flowers.Then the deer began to eat the green leaves of the young trees.So the farmers thought of ways to protect their trees.Now the deer had nothing to eat and many of them died.
The number of trees,deer,tigers,wild flowers and plants has changed much---less and less.We need to do more to keep the balance of the nature.
Now more“Great Green Walls”are needed to save a lot of land and wild animals all over the world.People try to plant many more trees and grass,to protect wild plants and all kinds of wild animals,even tigers.People came to understand:to protect all living things on the earth means protecting people themselves.

自然的教训（这句我不确定）
如今,许多国家的树木过度砍伐和遍及全世界的洪水(情况)正变的越来越严重.由于这些,许多陆地消失了.这就是自然的教训（这句我不确定）
当人们搬进一个新地方,他们通常砍伐树木或是挖掉许多野生植物来得到农田.或许他们认为他们不能吃树木或是草皮,他们一点都不知道树木可以阻止洪水以及吹走,卷走泥土的风,这些野生植物中的很大部分是野生动物的食物.假如动物找不到足够吃的植物,它们就会死或者离开这个地方.
在美国的某部,例如,鹿喜欢吃一种野生的花朵,山中的老虎吃鹿.但人们杀了很多老虎老保护鹿,很快那里有了很多很多的鹿,它们吃完了全部的野生花朵,然后这些鹿开始吃小树的树叶.于是农户们想办法保护他们的树.现在这些鹿没东西吃了并且它们中的很多死了
数,鹿,老虎,野花,野生植物的数目已经改变的太多了-----越来越少.我们需要做更多来保护自然的平衡.
如今更多的绿色长城需要节约许多遍及世界各地的土地和野生动物.人们尝试种植更多的树木和草皮,来保护野生植物和各种各样的野生动物,甚至老虎.人们开始明白:保护地球上的全部生物其实就是保护人们自己.
