text: If you start to limit your car use and start using a bus, train, etc you are also saving so much money on gas. like the amount of money you save on gas you can be buying yourself those shoes you wanted or that game youve been wanting to bad. The world is filled with so much pollution and nasty chemicals in the air and some of that is because of your car.. trucks also have so much pollution that its just sickening. Wouldnt it be great if your kids and your grandkids wont have to use a car and they will actaully probably live longer because there isnt as many chemicals in the skies. We may be living longer then the people back then but they didnt have cars so they didnt have any issues with pollution.
