Last Sunday, my family went for walk in a nearby park. We wanted to breathe the fresh air and having fun there. However, when gone out, we found it was cloudy and smoggy (烟雾弥漫的). Only a few people were walking quick on the streets wearing their masks. I was wondering what was the matter when my little brother begins to cough loudly. Suddenly I realized that it was air pollution. So we had to go back to home that day. Smoke from cars, buses, and factories make the air dirty, that is harmful to our health. I think they all should do some thing to keep the air clean.

The environment pollution became more and more serious today. We will have no clean water to drink because of water pollution. And when trees cut down, some animals disappear. There is more and more of dirty smoke in the air. People’s health has been great affected by air, noise and water pollution. Many people have died of diseases causing by pollution. In order to live the better life, it’s time for us to protect our world. We should recycle, reduce and reuse things, that saves money and reduces pollution. Use things as long as possibly. Don’t use plastic bag. Besides, we must plant more trees and stop people cutting it clown. We hope our world will he more and more beautiful.

Last week several places in our city were blanketed thick yellow fog. Everything disappeared from sights, highways were closed and traffic jams are commonly seen in the streets. Many people, especial children and the old, had to stay indoors. As a result local hospitals were crowded with people which had problems with his noses and lungs. The polluting environment contributed a lot to this. To have a cleaner air we have to do more to protecting the environment. To live a better life we have to push on with the economy, and it will be meaningless if we have to achieve it at the cost of our air.
