text: The main advantage is a cleaner planet. Emissions that cars release play a large role in the world's air pollution. Carbon emissions create smog that makes the sky grey, damages our lungs, and harms the plants that give us clean air. Due to carbon emissions from cars, Paris once had as much smog as "Beijjing, China, which is known as one of the most polluted cities in the world" (Source 2). If we start driving less cars it will have really beneficial implications for the environment, especially "... since transportation is the second largest source of America's emissions, just behind power plants" (Source 4). Imagine what positive effects banning cars would have on the population's and world's health.
