What History Says about Prior Collapses
Until fossil fuels came into widespread use, civilizations regularly grew until they reached limits of some sort, and then collapsed. There are many books looking at this issue. David Montgomery, in Dirt: The Erosion of Civilizations talks about the role soil erosion and soil degradation play in bringing civilizations down. Sing Chew, in The Recurring Dark Ages, talks about how ecological stress, deforestation, and climate change have led to long periods of collapse and low economic activity. Joseph Tainter, in The Collapse of Complex Societies, talks about how increasingly complex solutions to the problems of the day lead to ever-higher administrative costs that eventually become too expensive to afford.
Peter Turchin and Surgey Nefedov in the book Secular Cycles take more of an analytical approach. They look at how cycles actually played out, based on financial and other detailed records of the day. Their analysis considered eight economies, the earliest of which began in 350 B. C. E.. The pattern they found looks disturbingly like the pattern that the world has been going through since the widespread use of fossil fuels began about 1800: A civilization starts its existence when a new resource becomes available, for example by deforesting land to be used for agriculture (or in our case, finding ways fossil fuels could be used). A civilization experiences Growth for 100+ years as the population is able to grow with the new resource available to it.
