text: Likewise, in the excerpt "Paris bans driving due to smog" by Robert Duffer highlights how limiting car usage can help conserve resources. For example, "After days of near-record polution, Paris enforced a partial driving ban to clear the air of the global city...[The smog] rivaled Beijing, China, which is known as one of the most polluted cities in the world...Cold night and warm days caused the layer of air to trap car emissions." Going back to what Rosental was pointing out emissions are still triggering the atmosphere. But, that is not the only thing that is being blamed for pollution. "Diesel fuel was blamed, since France has...[a] tax policy that favors diesel over gasoline. Diesels make up 67 percent of vehicles in France, compared to a 53.3 percent average of diesel engines in Western Europe, accoring to Reuters." Without any gasoline nobody will be traveling from one place to another so to conserve resources people are better off limiting the usage of their cars.
