text: First of all, the elimination of cars helps the environment. "Passenger cars are responsible for 12 percent of greenhouse gas emissions in Europe...and up to 50 percent in some car-intensive areas in the United States" (5). In other words, cars are higly responsible for the harmful gases that pollute our atmosphere and cause global warming. In Paris,  a partial driving ban was issued to clear the air after days of high air pollution rates. After the driving ban, "congestion was down 60 percent in the capital of France after five-days of intensifying smog" (14). By using cars less, citizens can reduce pollution and help keep our earth clean and safe. Statisticts show that fewer people  are using cars around the world. "A study last year found that driving by young people decreased 23 percent between 2001 and 2009" (41). Sociologists belive that this trend will continue and possibly increase. They belive it will "have benficial implications for carbon emissions and the environment, since transportation is the second largest source of America's emissions" (34).
