Today ,as the living condition developed ,we live in a very happy and comfortable life.And more and more people are more dying to live in city.On the one hand ,some young people who just graduated from college can easily find a good job .The transport is more convenient for students and some clerks .And on the weekend ,we can have a good time in the parks and restuarants ,we also can go there to have a good rest .But on the other hand ,living in city is force to some people who can't afford to a high consumes ,because the living condition is high .And as more and more people come to ,it has a crowd .And the fresh are polluted by us ,so ,the environment is of a poor quilaty.
So,whatever the living conditions developed ,we need protect our environment!
