Why not bike?
Did you know that you could save 407 gallons of gasoline each year – half the amount burned by a car annually, if you biked to work instead of driving?
Bicycling reduces dependence on scarce, polluting oil supplies almost completely. You can travel hundreds of miles by bicycle on no more than a thimbleful of oil.
Bicycling creates no air pollution. Because you do not burn any kind of fuel but your own when you bicycle, you can ride through the environment without leaving a trace (noxious or otherwise!).
Bicycling is great exercise and helps keep your weight under control.
