[Confusion]

I think it's a quite informative set of graphs that provides interesting information about which resources, and hence which technologies, can be expected to increase in price, relative to other technologies, within the next decennia.

The fact that you consider something meaningless does not make it flawed. The legend clearly states these predictions are based on current demand, so the only flaw is in the person that thinks these graphs indicate when we will actually run out of these resources. You are perfectly right about that: that requires economical considerations.

True, but the fact that this issue is covered clearly by larger thinkers in Econ 101 does make it meaningless in terms of "conservation" or "planning for the future".

This hole idea is so common they gave it a name: Malthusian (http://en.wikipedia.org/wiki/Malthusian_catastrophe)

And there have been empirically proven answers to this question. (http://en.wikipedia.org/wiki/Julian_Simon)

If this chart means anything, it really only applies to commodities brokers, not to end consumers.
