Group work Possible answer: At our school, many things are done to protect the environment. Every week, recyclable waste is collected from each classroom, and materials such as paper, plastic bottles, and cans are sorted into special bins. To save electricity, lights and computers are always turned off when not in use. Additionally, paper is required to be used on both sides whenever possible. Last year, positive changes were made. The sports field was cleared of rubbish, and trees were planted to support local wildlife. Further steps will be taken soon. For example, old uniforms will be collected for recycling next term. Through these efforts, our school environment is gradually being improved and will be better protected for the future. Homework Must do 1.
