Riding a bike instead of driving can help save water, energy, and the environment while providing personal health benefits. It takes nearly 13 gallons of water to produce a gallon of gasoline, but biking saves those gallons. If just 5% of commuters in New York biked instead of driving, it could reduce carbon dioxide emissions equivalent to planting a forest the size of Manhattan. Biking to work for 30-60 minutes daily is also associated with lower blood pressure and stress.
