I use to live in a beautiful small town which was surrounded by green trees.And the river was clean in which we can see fish play happily. However, the house were small and simple, and the street was not wide enough for cars to drive on.Though people worked hard,they lived a poor life.Now great changes have taken place here.You can see tall buildings,department stores and factories everywhere.Cars and buses are running in the streets.But pollution is becoming more and more serious.A lot of trees are gone and fish have disappeared.Wo have to do our best to stop pollution.
