text: Some nations, such as Paris, France, find out about the downside of cars the hardway. Pollution is a very real problem in todays society. In 2014 the city had a near-record high of pollution, rivaling  Beijing, China, the most polluted city in the world ( source 2). After debating, the French ruling party decided to ban driving for odd and even liscence plate numbers on opposite days until the smog count went down. It took five days, but they managed to have most of the smog cleared. Decisions like these cause controversy everywhere, but we have a responsibility to our planet not to destroy it with greenhouse gases.
