Battlefield Earth

The environmental pollution is worse and worse today. Many trees are cut down, and water and air are polluted. As a student I try to have a low-carbon life to save energy and reduce pollution. Firstly, I often walk to 😁 school. It 😁😁😁😁😁😁😁😁 can reduce 😁 air pollution. Secondly, I always 😁 turn off the lights and fans when leaving the classroom. Thirdly, I always make full use of paper and other school things and never waste water. 😁😁😁😁😁😁😁😁 I wish more students to join me and make the earth more and more beautiful.😁😁😁😁😁😁😁😁
