For example, we can organize clean-up activities at weekends. By doing this, we can keep our environment clean, beautiful, and safe for everyone.

Second, we should plant more trees such as encourage students to plant trees or flowers in their school. In addition, they can also water small trees and flowers. This hepls reduce CO2 and make the air clean. Finally, we should set up more rubbish bins. For instance, we can put more rubbish bins in public places such as parks or bus stations.
