Do you know? April 22nd is World Earth Day. It tells us we should love the earth. Protecting environment is very important. We should be green(环保的). We can keep our bottles and take them to the bottle bank(瓶子回收站). We should have a black bin and a green bin at home. One for general waste and one for recyclable waste. We can use cloth bags and paper bags when we go to the supermarket. We should go to school on foot or by bus every day. More and more people live a low—carbon life.
