Bicing, the bike-sharing program of Barcelona, is saving lives.
The programs saved 9,000 tons of carbon dioxide pollution and 12 lives by promoting heart-healthy exercise. According the British Medical Journal, the health benefits of cycling outweigh the risks which include traffic accidents and the inhalation of air pollution.
In 2009 approximately 180,000 people used Bicing averaging two miles per day.
Bike-sharing has taken off around the world in cities like Parish, Washington D.C., San Francisco, and New York City.
