Recently, there is a hot debate about whether private car owners should be taxed for pollution. Some regard it as an effective way to control of the number of cars and reduce pollution in the city. But others don’t think so. I think that private car owners should be taxed. Firstly, taxing private car owners is a very good way to protect the environmment. It will increase the expense of driving cars, so that people will reduce the buying and using of cars. As a result of this, the pollution of the cars will reduce. Secondly, as I just refered, it will reduce the buying of cars. Therefore, the producers will sell their cars at cost, so that people who cannot afford a car would have a chance to buy a car. This is conduce to justice of the society. Third, because the taxing of cars, the car producers will turn to improve their products. Consequently, they will invent some new cars, whose emission levels will be in a more environmental condition. I think it will contribute to an improvement of cars' quality. All in all, taxing private car owners is a win-win measure, it not only do good to the producers, but also do good to the consumers. More importantly, it is an environmental action.
