As a tour guide, I am glad to tell you that more and more tourists are paying attention on environment protection. Several years before, in one place of interest,
I saw rubbish throwing away everywhere, such as waste paper, plastic bags. Besides, some tourist climbed trees and pick flowers. Some even scared or catch little animals. What’s more, some of them made a fire to cook, which may cause a forest fire. Recently great changes have been taken place. Most tourists take rubbish away with them while they leave. They no longer hurt little animals. Trees and flowers are well taken care. In the forest, smokers give up smoking so as not to start a fire. Now I sing high praise for so good deeds.
