Limits to Growth - Depopulation

The "Limits to Growth" is a report published in 1972, which details the result of early system modeling, pioneered by Jay Forrester of MIT, which sought to combine economic, environmental and demographic data into one combine systems model. This combine systems approach and integration of multiple datasets across multiple disciplines together yielded the "World Model" - which included predictions well into the 21st century.
Instead of describing in detail, their methods, approach and multiple different models. It is best to consider their base case, or standard world model as the authors considered this case to be the most likely outcome, and compare those modeled predictions to known empirical data ever since its publication in 1972. From this very simple comparison, the primary predictions of the standard model are objectively false, and wholly inaccurate to what has occurred since the time of publication. For example, world food production has steadily risen since 1972, additionally, production and refining of industrial metals has also increased keeping pace with economic growth. The base case model predicted a collapse in both before the current year.
