Writing
带布包去购物（cloth bag）
use public transportation instead of riding in cars
cut down air pollution
sort the waste into different kinds
use our own cloth bags instead of plastic bags
Good morning, everyone! Environmental problems are becoming more and more serious these days. I think each of us should do something to protect the environment.
First, we should walk, ride bikes or use public transportation instead of riding in cars when we go to school. Driving less helps cut down air pollution. Second, we are supposed to sort the waste into different kinds because some can be reused or recycled. Third, we should use our own cloth bags instead of plastic bags when shopping. Although plastic bags are convenient, they’re harmful to the environment. What's more, we should save energy. If we leave a room, we should make sure that all the lights are turned off.
I believe that if everyone takes action, our environment will become better and better.
