text: Our ecosystem is in dangered. All of the pollutio and waste that people put into the air needs to stop. The idea of having imited use of cars can provide a healthy and great looking earth. In the article by Robert Duffer ''Paris bans driving due to smog'' we see the understanding that paris can help support the idea for having limited usage of cars. ''After days of near-record pollution, Paris enforced a partial driving ban to clear the air of the global city'' a sentence stated in the article. Paris typically has more smog than other european captials. ''Last week Paris had 147 micrograms of particulate matter (pm) per cubic meter comparied with 114 in brussles and 79.7 in london''. With nobody driving their cars for a day, they managed to clear up alot of smog and make the earth look healty again.
