“The worst effects of breathing polluted air are experienced where it is densest: in traffic. Spending time on and near highways, freeways, and other busy roads is terrible for your health. How near is a question that is still being studied, but researchers believe that the effects are worst within either a fifth or a third of a mile. People in cars or buses are exposed to considerably more air pollution, perhaps because of, rather than despite, being in a closed space. People walking and bicycling on or next to roads breathe more air, but inhale somewhat less pollution; and cyclists have been found to have even less risk if they are on paths that are separated from the road.” HealthTrafficAir PollutionBicycling Book:Bikenomics: How Bicycling Can Save The Economy Source: Bikenomics: How Bicycling Can Save The Economy
“The best scenario of all when it comes to air pollution has nothing to do with tailpipe filters or hybrid, electric, or zero emissions car technology. The way to reduce pollution is to reduce driving, plain and simple.” SolutionsPollutionEmissionsCarsAir PollutionBicycling Book:Bikenomics: How Bicycling Can Save The Economy Source: Bikenomics: How Bicycling Can Save The Economy
