How to cut down plastic pollution
(首段）The environmental problems are getting more and more serious. So, it’s important for us to take actions to protect the environment.
（正文）First, when we go shopping, we’d better bring our own bags instead of buying plastic bags. Second, when we buy takeaway food, we are supposed to avoid using the one-off products like plastic forks. What’s more, remember to work on waste-sorting before throwing rubbish. At last, It’s important to make the people around us realize the importance of protecting the environment.
（结尾） Let’s take action together! Our actions can make a big difference and lead to a better future!
It’s our duty（责任） to protect the earth –our home！
