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.
