text: First of all, one main advantage of limiting car usage is decrease of pollution. In the article 'Paris bans driving due to smog' by Robert Duffer he says "After days of near-record pollution, Paris enforced a partial driving ban to clear the air of the global city." The pollution had gotten out of control, and had to be decreased. Duffer also states "Congestion was down 60 percent in the capital of France, after five days of intensifying smog . . ." As a result of the ban, pollution decreased. Limiting car usage can decrease pollution.
