Biking to work is good for your health and good for the planet since your bike won't emit harmful pollution. If your commute is too far to go all the way on your wheels, then just bike some of the way. Pack your bike in your car, drive part of the way, then park your car, get on your bike, and finish the commute on your seat. If you ride the bus to work, bring along your bike and get off a few stops early so you can bike the rest of the way. You'll burn calories, strengthen your heart and quads, save money on gas, and you'll be cutting down on air pollution. Just be sure to wear your helmet for safety.
