How to Protect Our Environment
Our environment is becoming worse and worse day by day. Now we can’t see blue sky in the cities in the daytime. There is no fish in the dirty rivers or lakes. Even worse, a lot of people can’t drink clean water. It’s time for us to do something to protect the environment. As a student, we should ride a bike or walk to school every day. We shouldn’t pour waste water into rivers. And don’t throw rubbish here and there. If everyone makes contribution to the environment, it will get cleaner and tidier soon.
