text: In addition, it may be more calm without cars but it is also better for you and the enviroment. "passenger cars are responsible for 12% of greenhouse gas emission in europe... and up to 50% in some car-intensive areas in the United States."(5). Wherever you are in the world greenhouse gasses will most likley affect your environment in some unnatrual way and that is not the best thing for you, the people you know, or all the plants and animals. Without cars polluting earth we would be way more healthy and many animals may not be endangered or extinct like they are today."how much you drive is as important as whether you have a hybrid."(7). If you drive less its not just better for the environment and your health it can also be better for your wallet. If you drive less you save money on gas that you can use for many other things. Overall driving less turns out to be better for everyone.
