text: One main reason limiting motor vehicle transportation would be the best thing to do for the environment is because of the fact that, for example the exhaust of the vehicles in a densly populated area would cause a lot of physical damage to parks or gardens. The gasses that come out of the exhaust prevent full healthy growth of plants, which in terms means less trees and we need trees to help turn carbon dioxide into oxygen so we can breathe. It also helps us to breathe better if we could all just carpool with friends because it would cause less vehicles to be out on the road and in turn create an environment where all those chemicals aren't coming out of as many cars.
