I used to live in a beautiful small town with green trees all around it.The river, running through the town, had clean water in which fish could be seen swimming in groups. The house, nevertheless, was small and simple. The street wasn't wide enough to run cars. Citizens here worked hard all year round yet lived a life of no more than poverty. Now great changes have taken place here. You can see tall buildings, department stores and factories everywhere. Cars and buses are running in broad streets. But with the development of industry, contamination is becoming more and more severe. A lot of trees are gone, and fish has disappeared because of the dirty water. To our joy, people have been doing their best to stop pollution and make the town even more beautiful.
