text: Now lets think of air pollution that has rose our global warming levels. If you were to ask someone "what's the biggest reason for global warming"? The first thing that would come to mind to almost everyone would be air pollution caused by cars. This isn't just in the US, this is going on everywhere in the world, but some places are finding solutions for this problem. For example, in the article "Paris bans driving due to smog" paragraph 1, it says "After days of near-record pollution, Paris enforced a partial driving ban to clear the air of the global city". That's a perfect example of limiting car usage that can be extremely beneficial to us and our earth.
