In a paper published by Spanish investigators in the British Medical Journal early this month, they found that bike sharing (in 181 982 participants) can actually help save lives in urban environments.
After accounting for air pollution and traffic mortality, the authors found that bike sharing prevented the deaths of at least 12 people each year as a result of the exercise. Annual carbon dioxide emissions were reduced by about 9 062 344 kg.
