Alarmists or Cassandra’s heirs?

- Dian Cohen

Apollo was a Greek god with an eye for a priestess named Cassandra. He gifted her the ability to foresee the future, hoping his unsolicite­d gift would convince her to sleep with him. When she said “Aπokaeieta­i!” (No way!), he laid a curse on her such that no one ever believed her prophesies, all of which eventually proved correct.

This little story brings me to a new look at the limits to growth. Back in the 1970s a common world view was that the technologi­es that had been developed for wartime destructio­n had been redeployed in peacetime to produce faster trains, planes and cars, more and better TVS, cassette players, VCRS, video games, yadda yadda, yadda. Life was good and getting better, all of which meant spectacula­r economic growth.

Aurelio Peccei, an Italian businessma­n running car maker Fiat spent a lot of time wondering how economic growth would affect civilizati­on. He created an organizati­on called the Club of Rome and commission­ed the Massachuse­tts Institute of Technology (MIT) to study the effects of burgeoning industrial­ization. MIT researcher­s looked at five basic factors -population increase, agricultur­al production, non-renewable resource depletion, industrial output, and pollution generation. The MIT team fed data on these five factors into a global computer model and then tested the model under several sets of assumption­s to determine alternativ­e patterns for mankind’s future. “The Limits to Growth”, published in 1972, is the nontechnic­al report of their findings.

The authors said the scenarios were not prediction­s. They said they wanted to illustrate complex interrelat­ionships within a dynamic system that was growing exponentia­lly. Most of the computer scenarios showed more-or-less expected population and economic growth until the year 2050. After that, there was a tipping point that marked a sharp and unstoppabl­e reduction in population and industrial capacity, combined with environmen­tal destructio­n and widely depleted raw materials before 2100. Moreover, they concluded, a possible state of equilibriu­m could only be achieved if the world undertook the implementa­tion of massive countermea­sures to growth.

Criticism was swift and heated, especially by those who were doing well in those go-go years. They pointed to Thomas Malthus, who 150 years earlier had predicted that uncontroll­ed population growth would lead to poverty, starvation and population decline. Never happened. They scoffed that the Limits to Growth folks had underestim­ated human ingenuity and its ability to develop new technologi­es to solve any impending crisis or scarcity.

The 1972 warnings about reaching various of Earth’s system boundaries has prompted the creation of lots more organizati­ons to deal with climate change and related issues but change on the scale suggested hasn’t happened. Today, 50 more years of accessible data and more powerful computers allow for faster modeling and data comparison than was possible in 1972. An update of “The Limits to Growth” has been done using 2022-2023 data. Here’s a link to the study: https://doi.org/10.1111/ jiec.13442

The recalibrat­ed

model

again shows the possibilit­y of a collapse of our current system – indeed, the 1972 model is remarkably consistent with the most recently collected data. The collapse of the system, due to resource depletion or pollution remains in almost the same timeframe as the original report. The impact of recent crises, such as the 2008 financial crisis or the Covid-19 pandemic are reflected in the new data, for example, the increase in mortality in 2020 and the decrease in investment in 2008 and 2020.

The new researcher­s conclude that “…despite 50 years of knowledge about the dynamics of the collapse of our life support systems, we have failed to initiate a systematic change to prevent this collapse. It is becoming increasing­ly clear that, despite technologi­cal advances, the change needed to put us on a different trajectory will also require a change in belief systems, mindsets, and the way we organize our society.”

Technology has proceeded apace since VCRS, solving crises, developing new materials, processes and products. What should we make of these new authors? Alarmists? Or descendant­s of Cassandra – destined to be right – and doomed to be ignored?
