text: Next, is how some people attempt to slow the car pollution. The first example of a community trying to decrease the usage of cars is Vauban, Germany. In Vaubaun street parking, driveways, and home garages are generally forbidden. For the most part, Vauban is car free. The only way to use cars in Vauban is to carpool because there is only two places to park in the whole city and they are two large parking garages on the edge of development. Then you have to pay $40,000 to keep a spot. 70% of the people in Vaubaun do not own cars. Anoter example is Paris, who is one of the biggest air pollutants next to Beijing. They have been trying to decrease the smog in their area through slowing the amount of cars on the road. What they did is make it so only cars wih even-numbered license plates could drive one day and odd-numbered license plates the next. Almost 4,000 drivers were fined due to this policy, which showed some  reluctance in following the plan. This did not matter though because the smog cleared enough to where the polcy only lasted for one day. Another attempt in lowering the usage of cars was Bogota's car-free day. In this program it is quite obvious that it was just a day of no car usage at all. During this event Colombians hiked, biked, skated or took buses to work. Even in the rain people of Bogota participated in this event. Then there is one other case of lowering the usage of cars, which is the natural way, having people just grow away from the car. This is currently happening in the United States, one of if not the largest car users. Like I said earlier since 2005 the usage of cars has decreased. Whether this trend stays in motion or not depends on the idealism of the current and future generations.
