The end of our industrial lifestyle paradigm will be dictated by Liebig’s Law, and by humanity’s response to its consequences. Unfortunately, it is impossible to know at this point which increasingly scarce nonrenewable natural resource (NNR) or NNR combination will ultimately prove to be industrialized humanity’s limiting factor.
Consequently, humanity’s global societal collapse may be triggered by scarcity associated with one or more NNRs other than those commonly considered “most critical” to the perpetuation of our industrial lifestyle paradigm—fossil fuels, or oil specifically. After all, the space shuttle Challenger disaster was caused by a faulty o-ring.
