I used to live in a small town with trees all around. There was no tall building and the only street was narrow. Just outside the townï¼ there was a river. You can see different kinds of fish swimming in the clear water. People here lived a simple life.
Great changes have taken place here. You can see tall buildingsï¼ big department stores and factories everywhere. Different kinds of cars and buses are running in the big streets. But with the development of the industryï¼ we have fewer trees. Air and water pollution is becoming more and more serious. We must do something to stop pollution and make our town even more beautiful.
