text: Cars are one of the leading reasons pollution is such a big problem today. So one advantage to having less cars would be less pollution. Experts from source two state that up to fifty percent of greenhouse gases could come from the United States alone. Acoording to source two places like Paris have already begun to face the effects of pollution. The pollution in Paris was bad enough to ban cars to reduce the amount of smog in the air. In doing so the lack of cars helped cleared the air for people to breathe easier. Banning cars would also promote an increase to public transportation. With less cars people would be obligated to use public transits or simply walk to where they needed to be. A buisness man from source three named Carlos Arturo Plaza states "It's a good opportunity to take away stress and lower air pollution". This shows that not all feedback from the loss of cars is negative.
