"Last week, the journal Environmental Health Perspectives published findings  from a study by scientists at the University of Wisconsin on the  economic and health benefits of switching from a car to a bike for trips  shorter than five miles long in 11 metropolitan areas around the upper  Midwest.
Combining data on air pollution, medical costs, mortality  rates, car accidents, and physical fitness, the researchers found that  if inhabitants of the sample region switched to bikes for half of their  short trips, they’d create a net societal health benefit of $3.5 billion  per year from the increase in air quality and $3.8 billion in savings  from smaller health care costs associated with better fitness and fewer  mortalities from a decreased rate of car accidents…”
