text: To introduce my statement i believe that that one of the many great advantages to limiting car usage is that there will be less pollution. Based on source two Paris typically has more smog than any other European capital. Paris had 147 micrograms of particulate matter. Since everyone in paris stopped driving for a week the smog cleared enough to rescind the ban for odd numbered plates because they were fining people that had odd numbered plates. Many blamed diesel fuel but it couldve been a matter of different things but it was mostly from exhaust pipes and diesel fuel.
