The Yunwu Mountain is a place of interest, which attracts many tourists every day.

　　Years ago, some of them paid no attention to environmental protection. They threw about waste paper, plastic bags and tins. Besides, they killed animals, caught birds, dug up trees and picked flowers. What’s worse, they often made fires to cook in the forest. That was dangerous. Changes have taken place now. People realize it is important to protect the environment. When tourists leave, they take away the rubbish with them.

　　They no longer hunt animals, and they take good care of those plants. All the tourists carry their lunch in order not to start forest fires. We must sing high praise for those good deeds.
