Đáp án: There are so many ways to keep the evironment green. We can recycle many thighs like: plastics bottle, plastic bag,... Buts I think recycle the plastic bottle is very popular nowadays. Because we can make many things from plastic bag like: use it to put pens and pencils in it, use it to make somethings to decorate your home,...
