text: Also lets not forget one of the biggest issues in the world POLUTION! Pollution is a huge problem that we constantly see on the news , hear on the radio , and we see every day. One of the worst forms of pollution is the kind thats in the air we breathe to live and cars play a role now alot of people may say "my one car cant possibly cause that much pollution" but if millions .. billions of people think the same way then thats billions of air polluting cars driving around the world polluting the air we breath to live! Paris made a great arangement as stated in the article  "PARIS BANS DRIVING DUE TO SMOG" they talk about how paris banned certain cars driving from one day and other cars the next . All the cars with  even numbered liscense plates were to not be driven on monday and vice versa for the odd numbered liscense plates the next day. this was good because it only allowed about half the amount of cars that usually drive on a daily basis to drive. In time this should make quite the noticable difference in the smog and the overall experience of breathing the " fresh air".
