Economic development and environmental protection are related closely.But as the economic develop so fast,we always ignore the protection of environment.
In my opinion,we can't enjoy our lives without a nice environment.The Economic development brings us abundant ways of fun ,but at the same time ,it brings a lot of ruinnings.Too much factory,too much rubbish,the environment is getting more and more terrible.In many big cities,we cound found that there is too much smoke in the sky so that we even couldn't see something clearly.Sometimes when we walk alone the street ,we could found the air is smelly and go back home.
As far as i am concerned,i think environmental protection is as important as Economic development and we should pay more attention on it!
