text: Vauban isn't the only place that has enforced the rule of not using cars. Many other places have done so also. Robert Duffer states, "After days of near-record pollution, paris enforced a partial driving ban to clear the air of the global city." By saying this the author is explaining how the use of cars have dramatically polluted a city. Just think, if there were no cars, then there would be less pollution to worry about hurting all the city's. It is not hard to ride a bike to the places you need or want to go. Instead of using cars everyday and hurting our enviroment, people should think of how much good they would be doing and money they would be saving by taking another type of transportation than just cars.
