William (Patrick) Ophuls has written a tight book exploring this called “Immoderate Greatness” (2012). He concludes that collapse is inevitable. As civilizations prosper they inescapably outgrow their resource base (most often in the past it’s been topsoil and soil fertility) and that sets in a decline that initially goes unrecognized because of human hubris. “We’re so smart progress can never reverse.” Continuing business as usual during the decline compounds the ecological overshoot and drives the collapse. Sound familiar? Difference now, of course, is that previous collapses have had limited geographies.
