Should private car owners be taxed for pollution No one can deny that there are more and more cars in the world, which would also cause much pollution. No double that it is very convenitent for us go out by cars, but we have become more lazier than before. In other words, we don't want to riding bikes or jogging again. So i'd like to say that private car owners be taxed for pollution. Can you imagine that you encounter a traffic jam situation. Of course not. On the one hand, a growing numble of people willing to drive cars instead of taking bus, which harm to environment. In addition, there are many traffic accidents just because people who don't obey traffic rules. On the other hand, if we use this system, fewer people would rather ride bikes than use car. However, ride more bikes or run is benefit for us. To sum up, in order to protect environment, I suggest that we can ride bikes, which is one of the fashionable sports in the world.
