As we all know, the environment around us is getting worse and worse. In many cities we can’t see fish swimming in the rivers or trees on the hills. Some people even have no clean water to drink. People will get sick without a good environment. So we must do something to protect ourselves and the environment.
But how to protect our environment? I think we can do some things like going to school on foot or by bike instead of by car. We had better use shopping baskets instead of plastic bags when we go shopping. We should use both sides of paper when we write. Don’t use paper cups. At our school dining hall, we can use our own bowls and chopsticks. We can reuse the water and save electricity.
In a word, if everyone pays more attention to our environment, there will be less pollution and our life will be better.
There is only one Earth. I hope everyone will protect our environment well.
