It's everyone's duty to protect the environment.保护环境是每个人的责任和义务

With air quality becoming worse and worse, the smog climate has been more common than before. In order to protect our environment, we should take action right now. Here are some useful suggestions for us. First of all, we had better take a bus, ride a bike or walk instead of driving private car, which is friendly to our environment. In our daily life, cloth bags can be used when going shopping, because plastic bags can’t be recycled. Besides, we should turn off lights to save energy. Both sides of paper can be rewritten. What’s more, rubbish should be sorted(分类). Last but not the least, we must plant as many as trees and flowers as possible. We can not only make our environment beautiful but also make our air clean and fresh.

I hope our world will become a better place to live in through our efforts.
