Evidence: According to Source Two, Paris, a city known for it's aromatic scents, was covered with the smell and appearance of smog for days (they had near-record pollution: Paris had 147 micrograms of particulate matter per cubic meter compared with 114 in Brussels and 79.7 in London). After a day in which all even-numbered license plates were banned from the streets of Paris, the smog cleared up a great amount (enough for the city officials to take the ban they had placed for odd numbered license plates the next day). The smog that was affecting the well-being of Paris' citizens had mostly disappeared after only one day of limited car use. If a community limits cars, its inhabitants will be almost forced to exercise more. According to Source 3, in Bogota, Colombia, where a "Day Without Cars" is held yearly, 118 miles of bike paths have been constructed, the most of any Latin American city. Less cars on the road in this city have led to other means of transportation being more popular, including walking and bicycling. These ways of getting around are much more healthy then their gas-powered alternative. Less traffic on roads will therefore leave cities healthier than otherwise.
