My name is Li Ming. I am a middle school student. I go to school on foot every day. I always remember to turn off the lights, the TV and the fans when I leave the classroom. When I am not using water, I always turn off the tap. I often reuse water, for example, when I finish washing the clothes, I use the water to clean the floor and water flowers. I never use plastic bags. I think saving paper is necessary, so I often make full use of paper. It's important for us to live a low-carbon life to protect the environment.
