Stop air pollution in China

Along with the rapid economic development in China, air pollution has become more and more severe. the air in every big city in China has, to some extent, been polluted by factories and cars on the road. Particularly, on rush hours everyday, it is hard to breathe for people who walk on the street if there is no wind or rain.
Shall let this situation go worse and worse? No, certainly not. So what shall we do to prevent people from polluting our air? I believe that on one hand, every local government should restrict the number of cars on the street, so that air in the city can be kept cleaner. Moreover, public transportation shall be encouraged by government and people as a whole.
