Meadows, D. H., Meadows, D. L., Randers, J., & Behrens, W. W. III (1972). The Limits to Growth. New York: Universe Books.
Commissioned by the Club of Rome and produced at MIT using the World3 systems-dynamics model, The Limits to Growth is the first computational demonstration that exponential material growth on a finite planet produces overshoot and collapse unless the growth trajectory is deliberately altered. The model tracked five variables (population, industrial output, food production, resource depletion, pollution) and ran twelve scenarios. The “standard run,” which assumed no major policy changes, projected overshoot and decline in the mid-twenty-first century. The “stabilized world” scenarios showed that early action on resource efficiency, pollution abatement, and population stabilization could produce a sustainable equilibrium, but only if undertaken before the system crossed critical thresholds.
The book’s reception followed a pattern the S-curve thesis would predict: rejected during the acceleration phase. Mainstream economics dismissed it for underestimating substitution, technological change, and price-driven adaptation. The 30-year update (Meadows, Meadows, & Randers, 2004) showed the original standard run tracking observed data more closely than any of the optimistic critiques. Turner’s 2008 and 2014 comparisons at CSIRO confirmed the alignment.
For the BioConomy corpus, Limits to Growth matters on three counts. First, it established the structural argument that material throughput has a ceiling, which is the condition under which retention economics becomes necessary rather than optional. Second, its scenarios are early descriptions of the S-curve inflection: the point where an exponential growth trajectory bends toward either stabilization or collapse, depending on whether the system reorganizes. Third, and most consequential for the two-factory frame, the report describes the deceleration of the mechanical factory without naming the acceleration of the ecological factory. The degrowth tradition that followed (Georgescu-Roegen, Daly, Latouche, Hickel) inherited this single-factory perspective. The two-factory frame completes the picture: what Meadows modeled as the system’s ceiling is, seen from the ecological factory’s side, the moment when a different form of production must scale.
