text: We all know how badly cars gases are are and that without those harmful gasses there wouldn't be much fog. now imagine if this happened here in America. In Paris they band driving due to the near record pollution. They did this so they could have a day where the air would clear out and there wouldn't be that much fog. Some might think this is an excellent idea, but some might say its a very lousiness idea. Limiting car usage actually helps because your limiting how much of those harmful gases you put in the air. They tried this for a certain amount of time in Paris and that do you know! The smog cleared up enough for the ruling French party to rescind the ban for driving your cars. Now this is just one of the many great things limiting car usage has on our planet.
