text: Car emissions all over the world are among the main causes for the air pollution and greenhouse gasses. In cities llike Paris the air pollution rose so much that there was a temporal driving ban on the whole city. This ban eventually cleared the air but if this could happen in one city it is more than likely to happen again in another city. These car emissions are clearly a large part of this air pollution as Elisabeth Rosenthal shows the U.S  has a fifty percent of greenhouse gas emissions from the abundant amount of cars. Limiting the car usage would clearly diminish the amount of emissions in the air and prevent these large amounts of smog and pollution to form in the air that the people are breathing.
