"In the same way, it is not necessarily paternalistic to advocate the restriction of air pollution. Individual citizens and firms may produce more air pollution than any of them actually want because they know that there is little to be gained from uncoordinated individual restraint. If I avoid driving a gas-guzzling car, the impact on the overall level of air pollution w ill be utterly insignificant. So I have no incentive to take it into account in making my driving decisions even if I care greatly about reducing air pollution. Widespread public ignorance is a type of pollution that infects the political system rather than our physical environment."
