text: Transportation is really big in America. People drive all the time, were a moving country. So driving and using cars does effect our enviornment. One big thing going on is smog. One country that i can point out is Paris. Paris had so much smog that they enforced a partial driving ban to clear the air of global city. "Congestion was down 60 percent in the capital of France, after five-days of intensifying smog..." according to the article Paris bans driving due to smog by Robert Duffer. Paris has more smog than other european capitals. Which is really bad because that can effect us as humans. In Bogota They are doing a program that involves banning cars for a day. The goal was to promote transportation and reduce smog which it did. So limiting car usage can improve safety and make the environment more clean.
