This is the stupidest thing I've read in a while. You can get growth by more efficient use of resources, however 'finite'. My flat-panel monitor uses a fraction of my old crt-based one, meaning I get far more display time for a unit of energy. That's replicated throughout our economy. Not to mention that we get increasingly good at locating and exploiting resources, deep-water oil drilling being one example. Consequently, the costs of those resources keeps going down as Julian Simon's bet with Paul Ehrlich made clear. Disregard anything this dope has to say.
In an sense it is. But the Malthusian delusion holds an intuitive grip on the minds of lots of pretty smart people.
It's difficult to explain how positive feedback into a complex system throws all of the assumptions about resource limitations of the system out the window. When the positive feedback comes from smart people who can make money by solving problems, Malthusian limits--however intuitive--have never panned out. What works for lemmings doesn't seem to work for humans.
History is full of failures of the predictive power of Malthus' thinking. Our task is explaining why to folks who are satisfied with their zero-sum intuition.
Lots of conservatives don't know this either.
