I used to live in a small town with trees all around. There were no tall buildings. People there lived a poor life. Now great changes have taken place in my hometown. You can see tall buildings and factories everywhere. Many people have their own cars. But air and water pollution is becoming more and more serious. The mountains are not green, the rivers are not clean, and the sky is not blue. I think we must do something to stop pollution. I hope my hometown will be more beautiful in the future.
