My classmates and I joined in actively, and it became an unforgettable experience. We decided to make something creative with waste. We collected old boxes, plastic bottles and used cloth at home. 37 After three days of working on it, we made a “multi- functional storage shelf”. Our work won the “Most Creative Award” in the school’s exhibition. During the week, we also volunteered to encourage garbage sorting on campus. We made posters to explain how to sort different types of garbage and helped younger students put waste into the right rubbish bins. Many students said they learned a lot from us. This activity taught me that we can turn waste into treasure with creativity. It also made me realize that everyone can do their part for environmental protection. I will keep doing small environmental actions in daily life to make our planet better.
