That said, wave your arms all you want, talk about spilled milk all you want, the fact will remain that vehicle emissions are a major contributor to air pollution. As of 2011, there are over one billion cars in operation daily on planet earth. The implications are obvious. --- |

That depends on what air pollution you are talking about; 80% of volatile organic compounds in the US, which combine with NO2 in the presense of sunlight to produce smog, come from biological sources, e.g. trees. If you are talking just about air pollutants generated by humans, all transportation, cars, trucks, ships, airplanes, etc., accounts for 27%. -- Jim Pennino |
