The underlying systems dynamics
model... Under Limits to Growth is driven by the Systems
Dynamics Model World3
Synopsis of the 30 year update is
here: www.flow.ph/limitstogrowth/world3
This graph shows the number of
Earths required to provide the resources used by humanity and
to absorb their emissions for each year since 1960. This human
demand is compared with the available supply: our one planet
Earth. Human demand exceeds nature's supply from the 1980s
onward, over‑shooting it by some 20 percent in
1999. (Source: M. Wackernagel et al.)
A quote for those of us who figure
that necessity is the mother of invention (i resemble
this,fyi)
"In short, society develops
technologies and markets that hasten a collapse instead of
preventing it."
Any scenario or simulation which doesn't mention World3, or
Limits to Growth is likely to be a suboptimal view of reality.
IMHO, if you are not wiring
anything you do into this model in some form, you are
participating in the problem!
