They're Getting Better at This

Now environmentalist wackos recognize they have to cite something resembling historical evidence before making predictions outside of anybody's experience. In this case, they attempted to buttress warnings of “resource depletion” by claiming Mesopotamian civilizations or the Roman Empire collapsed due to resource depletion.

On the other hand, it's still bulshytt. If the Mesopotamian civilizations collapsed due to resource depletion, it's amazing how the resources undepleted themselves in time for the Caliphate. If the Roman Empire collapsed due to resource depletion, it's amazing how the resources undepleted themselves in time for the Renaissance.

As far as I can tell, the major cause of civilization collapses is contagious disease. That might include the contagious mental disease called collectivism.

I suppose I should also include a word or two on why resource depletion is unlikely to be a crisis. Resources, in the sense they are finite, consist of atoms and energy. Atoms aren't usually used up at all, and the two hundred quadrillion watts of solar energy hitting the Earth is vastly greater than that consumed by humans. The only resources that can be depleted are fossil fuels and wild fish. Both of those should be obsolete soon.
