we have stepped in a big era which  our society is fast developing since the industrailization began from 19th century. but also,it accompaied lots of confusions which the damage of earth maybe is the most serious one .we can't be so delight with the progress we have made that forget the responsibility for the earth. we must face the truth that we have abuse the resource that earth offer that brings big hurt to this beautiful blue planet.

firstly,beacuse of the enormous need of energy and raw material,we have cut down lots of forest,and then what's becoming worst is the sand has been blowing by wind that brings the deterioration of the enviorment,the deeper damge of the earth.for instance, the area of Qinghu was ever a beatiful place covered with big forest ,but since 1970s the woods had been cut down little by little and finially absolutely disappeared, it's no longer a suit travelling place but a place lack of water and merely people live in.

secondly,the pollutant we produce also makes bad effect to the earth.everday, we are inputting  a large amount of polluter such as garbage,exhaust gas and dirty water in the nature that it can't afford , so we can obviously realize that our earth gets weaker and weaker. this is why we can often hear bad news on the enviorment from Tv daily newsreport.

so ,all in conclusion,because of the excess activity we do to the nature ,our planet is suffering big damage,and we must alter the manner we used to do to the earth.
