text: Scientist have long realized that cars are a major cause to the pollution brought into society. From the waste produced while turning precious oil into gasoline, to the engines in millions of cars simultaneously burning gas. It is for this reason that limiting the use of cars would assist in saving and maintaining the environment. According to Robert Duffer, the author of the article "Paris Bans Driving Due to Somg", "Congestion was down 60 percent in the capital of France, after five-days of intesifying smog." What is also noteworthy is that this experiment by France officials was only in place for a matter of days. So after having smog that repotedly rivaled Beijing, China, the smog capital of the world, the smog that inhabited France was more than cut in half. If this can work in such a large scale like France, then it isn't unreasonable to believe that this same process can be done in other major regions. Saving the environment has become a priority around the world in recent years, and the idea of limiting the usage of cars could help to achieve that goal.
