Reducing Air Pollution by 80%
Should we reduce air pollution by 80%? It seems radical, but we can do it at zero cost. From National Review:
The EPA’s own models predict a further 80-percent reduction in emissions from cars over the next 20 years simply from fleet turnover, never mind whether we move to hybrids or other technologies.
Newer cars emit less pollution, so replacing the old ones automatically cuts pollution. Recall that it has long been known that the best way of reducing air pollution would be to buy and junk old cars.
