Nowadays, environmental problems are becoming more and more serious. I think everyone wants to be a greener person. However, how to become a more environmentally friendly person? There are some ways to tell you. First of all, we should reduce the waste we produce. We should use both sides of paper and reuse plastic bags. Second, recycling can not only protect the environment, but also save money. So we should collect waste paper and soft drink cans. Thirdly, if you take a short trip, we'd better walk or ride a bike instead of taking a bus or taxi. It will save energy and reduce air pollution. Let's be more environmentally friendly. I think it's easy for you to do that, because facts speak louder than words.
