As tour guide, I'm glad to tell you that more and more
tourists are paying attentions to environmental protection. Several years
before, in one place of interest I saw rubbish throwing away everywhere, such
as waste paper and plastic bags. However, some tourists climbed trees or picked
out flowers. Some even scared or catch little animals. What's more, some of
them made a fire to cook, which might cause a forest fire. Recently great
changes had 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 of. In the forest, smokers give up smoking so as not to start a fire. Now
I sing high praise for so good deeds.
