. Air Pollution
The air around us is badly polluted.Because many factories burn coal.They emit a large amount of black smoke into the air. Besides,there are more and more cars in cities now.
There are some ways to solve the problem.First of all,we should ask the factories to stop giving out black smoke into the air.Secondly,we’d better ride bikes or walk instead of driving to work.What’s more,it’s a good idea to plant more trees and flowers.Finally,we need to recycle books and paper and stop using paper napkins.
I think everyone should play a part in solving the air pollution problem.
I’m sure that our actions can make a difference and lead to a better future.
