At present, disposable cups and plastic packaging are still common on campus. First, the school could encourage students to bring reusable bottles and provide more clearly labelled recycling bins. Second, classes could take turns running short campaigns on saving electricity and reducing waste. These measures would make environmental action part of daily school life and help students develop sustainable habits. I believe small changes made by many people can greatly reduce our school’s environmental impact. Yours, Li Hua $
