You know, there is a river near your factory. It was a beautiful river with clean water. Many lovely fishes were swimming in it. There were flowers and grass on it's banks. But we can't see it now. Since the factory opened, it becomes dirty and smiles terrible. The fishes die because the river is polluted by waste water. The environment is becoming worse and worse because of the polluted river. We must protect our environment, we must do something for the river! I think you can buy some machines to clean the waste water. Then, the river will be clean again. All the people around you will thank you very much! 　　A middle school student 　　Xie Kai .
