Abstract

Our present world is the consequence of the size of the human population and its domination of the biosphere through the combustion of fossil fuels. Since ~1950, there has been a sudden increase in the rate of human global energy consumption, economic productivity, and population growth. This abrupt departure of the system dynamics has been defined as the “Great Acceleration.” The accelerated population and economic expansion during the past 70 years would have been impossible without using fossil fuels. However, no studies have made an explicit connection between human population dynamics on a global scale and historical changes in energy consumption growth rates, economic growth, and the energy return on investment of fossil fuels (EROI). In this study, I apply a simple population dynamic model of cooperation/competition to decipher the effects of changes in these factors on the dynamics of the human population during the period (1800–2020).
