答案
The annual Arbor Day is approaching,we began to protect trees and trees in succession.Most of people think that only the Arbor Day will protect trees and trees,in my opinion,contrary,we can not only protect trees and trees in the Arbor Day downstairs,should the protected trees and trees.
Hundreds of millions of years ago,earth to kinds of animals possess exuberant,everywhere when plant vitality,full of green,however,much higher IQ of other animals,plants human beings appeared as if by magic as decreasing rapidly.That is because,humanity in order to build houses,and cut down trees caused.Partly because business needs,large teams of cut down trees set aside lots,used to build the building.Because many people without authorization,cut down trees and trees,so nature was damaged.
The disadvantages of many cut down trees.Everyone knows the trees can be recycled carbon dioxide,if large cut down trees,the number of trees will be sharp decrease of exhaled carbon dioxide,we cannot get cycle.Thick trees can impede sandstorm,before two years in Beijing,the whole city was encountered sand dust storm cloud this is because of the lack of protection caused by the trees.
Everyone knows zhongyuan two bay city!Previously,where rags and those of the tile is east one-story houses a cave,west a hole,the door is a piece of wood,street heaped rubbish,dirty level.Now zhongyuan two bay city building up apartment,mansion,the river,the river willows along with the breeze bottom swing gently,this is people realized that respect for nature and the importance of protecting the environment.
I hope everyone can protect the woods,protect trees,let urban life add a points green!
