Recently the topic of green travel has been widely debated which has aroused public attention and has been more and more popular with people. To some extent, it has become a fashion. Undoubtedly, green travel has a pround impact on both enviroment and social, for its significance cannot be denied.

　　Green travel, especially public transport, makes a positive contribution to the environment and society. On one hand, public transport has the potential to reduce transport CO 2 emissions, which is a major contributor to local air pollution and smog. In this sense, green travel makes the environment clean and gives people a healthy living environment. On the other hand, public transport plays an important role in reducing the social costs of transport include traffic jam and time taken away from the family while commuting and vulnerability to fuel price increases.

　　We have only one world we can live in. I hope through green travel can we protect the enviroment and save resources. In my opinion, no matter where we go, we are supposed to choose green travel. If you are near to the place which you go to, you can go there on foot or by bicycle. In this way can we protect our environmen and keep fit. If you are far away from it, you can choose going there by bus or by taxi with your friends.
