As we know, our health is closely connected with the degree of air pollution. Our air has become polluted and it is high time we took action to slow down the air pollution. In my opinion, there are some effective ways we can follow to prevent air pollution. First of all, we should lessen the emission of polluted gas. With the development of economy, lots of factories are producing large number of products with discharging great dirty gas which is polluting our air greatly. In addition, we should plant trees and beauty our forest. As we all know, green trees can beautify our air during their growth. Besides, we should also follow the environmental transportation methods and apply new resources. The vehicle cars are producing lots of dirty gas everyday. If we can take the bus or ride a bicycle to school or company, our air will not be polluted violently. All in all, these three ways are good for us to follow. I believe that our air will be clean if we take these measures day by day.
