how I can unify diamond and tainter
and recast diamond un active human agency terms - not passive agency
passive human agency: population grew. exhausted resources. collapse.
active human agency: resource extraction costs exceeded margin. collapse.
problem: rapa nui deforestation. can't divide by zero. they removed all the trees. so the cost to remove new ones from nothing is infinite and the margin on that infinite work is nothing.
problem: Chaco canyon drought. no water to remove.
summarize:
diamond: collapse is a result of resource exhaustion
tainter: collapse is a result of margin / profit exhaustion
diamond: why? declining returns per unit of work invested vs unit of resource extracted
tainter: why? declining returns
but why declining returns? exceeded carrying capacity - non sustainable extraction
