text: One of the biggest issues that cars cause is the carbon emissions that they release. In America, the second largest source of emissions are from cars (Source 4). This doesnt' seem like an issue to Americans, but in places like Beijing, China, which is one of the most polluted cities in the world (Source 2), emissions are very harmful. Citizens of Beijing have to wear mask when they walk around the city so that they don't get sick or poisoned from the carbon emissions. Even a 1st world country, like France, had carbon emissions that rivaled Beijing(Source 2). So as you can see, the emissions that cars give off could become a more serious issue in America, especially if you live in a place like New York City. If more cities become less congested, they will be much safer.
