As people are knowing more about PM2.5, they are becoming more and more concerned about their living environment. As students, what should we do?
First, we should ride bikes or take buses to school. Riding bikes is also good for our health. We should try our best to advise our parents to drive less. Try to walk or ride bikes to work. Second, we’d better use both sides of the paper. Don’t waste paper. Third, we should save power. Remember to turn off the lights when we leave the classroom. At last, we should plant more trees and flowers.
If everyone makes a little effort, the world will be more and more beautiful.
