Prudence Over Sustainability
For two centuries, free people have been proving the resource pessimists wrong. Now that economically constraining principles of sustainability are becoming the new orthodoxy, we risk throwing a wrench into an industrial engine that could propel us out of today's environmental problems.
CHICAGO – “Sustainability” is an increasingly popular term used to signal one’s virtue in contemporary public discourse, but it is a poor basis for sound public policy. It conveys a biologist’s view of the economy without any of the prudence that economists favor.
The biologist Paul R.
