We can do many things to make our school green. Remember the three most important words: reduce, reuse and recycle!
Reduce
Many people waste paper because paper is cheap. But we should use less paper so that we can save trees. Make sure you write or point on both sides of the paper so that nothing is wasted. This simple tip will cut your paper usage in half!Possible answerReuse
Many people like disposable cutlery because they don’t have to wash up. But these things aren’t green. Bring your own chopsticks from home and reuse them. Don’t use disposable cups or plates, either.
Recycle
We all eat and drink at school every day, so there are plenty of wrappers, bottles and cans to dispose of. But don’t just throw your bottles, wrappers and cans in the rubbish bin — support the school’s recycling programme! Put paper, plastic, glass and metal in the recycling bins.
Follow these steps and we’ll all have a green school!We can’t change the past but we can change the future! Save the environment and it will
save you later!It’s our world, take care of it! Let’s just rememberQuiz注: word 文档
