This post discusses a study that claims that of the three year increase in life expectancy from 1978-2001, five months of the increase came from cleaner air, vindicating the investments made in making the air cleaner. Dave comments:
Of course we'll have no way of knowing how much the life expectancy
would have increased without the "expense" i.e. the redirecting of
resources that would otherwise have been invested and ultimately
resulting in more comfortable and healthier lives for everyone.
This accounts for 5 months out of three years. where did the other 2
years and seven months come from? Who gets the credit for that? The
short answer is from the very same things that result in pollution.
Don't think so? then how did that kidney get rushed from California to New York overnight?
