In my opinion, first, we’d better not travel by car unless it’s necessary. Second, people should be encouraged to choose the public transport. They can take a bus or the subway. These ways of traveling can save energy and reduce air pollution .They can also improve the traffic condition. Third, if we travel a short distance, we should walk or ride a bike instead of taking a bus or a taxi.Traveling on foot or by bike provide us with a chance to make us stronger and healthier.In a word , I believe that we can improve the environment as well as our traffic condition if we all choose the green travel.
