text: If you gave up driving to everywhere you go, you wouldn't just help the world with greenhouse gasses, you'd also be helping yourself. People nowadays sit at home watching TV and snacking. But do you know how much walking and biking could do to help the health of people. This would be the case if there was a limitation on driving cars. Getting exersize is also a great stress-reliever. Also it helps with the nasty smog that's been mentioned. People wouldn't be breathing in harmful gasses if there was a limitation or ban to car usage in most contries. Air pollution effects all of us as human beings.
