My hometown I grew up at the countryside where surrounded by high green trees;Rivers beside the house,bright and clean water provide the fishes freedom game time in it.The house is simple ,the street is narrow,People lived here work hard and not fortune,but they felt happy enough.By now,the high building has stead of little house,the road width spread more than twice,So many cars running on the road that you can serely see the bicycles as before.Industry has proved speedly and the natural evironment had seriously broken.The trees reduced and the rivers has disappeared increasingly.This caused by industry pollution,we should action to protect our live environment and deal with the pollution.
