My hometown I lived in a small vallage. There were lots of trees and plants there. Lots of fish swimed in the clear river. All the houses were not big and the streets were small. All the people worked hard but they were poor. Now all of these are changed a lot. Many high buildings have been built there. There are lots of cars on the steet. The industries are improved, but the enviroment is getting worse. There is less trees and you can not find the fish in the river. We must focus on the pollution and put the job at the first place now. We should try our best to protect the enviroment.
