How to Protect Our Environment
The environment is becoming worse and worse. It has a great influence on people's health, especially the air pollution. But how can we reduce the pollution to protect the environment
I think we should begin with the following things. We should pick up the rubbish and throw it into a dustbin, and we should collect waste things like pop cans and plastic bags. What's more, when we go to school or work, we'd better not take a car. It's wise to go on foot or by bike.
It's our duty to keep our environment clean. Let's take action now! If everyone does some useful things, our environment will become much cleaner.
