Tools for Understanding the Limits to Growth: Comparing a Simulation and a Game

Abstract

During 30 years as a systems analyst and teacher, this author has been constructing models to understand and convey key principles related to the long-term causes and consequences of physical growth on the planet. In this article, he describes two different models that he has developed to accomplish these goals. One was employed as a computer simulation; the other functioned as an operational game. In comparing them, the author points out many differences between the two tools and indicates two important challenges for this profession.
