I use to live in a beautiful small town with green trees all around it. A river run through the town, the water very clean in it. Fishes in the river was big and fat, and swim in groups. The house was small and simple. The street was not wide enough to run the car. People still had to hard work in poor condition to improve their life. Several years had passed. With the development of economic, many tall building stand everywhere. You can see that house become wide and light, the street is no longer narrow on which have different car is running. The lives of people become rich. The town already has a great change. But the pollution is more and more serious, the water is no longer clean, fishes in the river have disappeared because of the dirty water, a lot of trees are gone. The work is urgent very much for stopping pollution. I hope the environment will become good.
