In his chapter of the report, Assadourian defines degrowth as an "essential and urgent" economic strategy to pursue in countries entrenched in overdevelopment (such as the United States) in order for those countries to be truly sustainable and adapt to "The rapidly warming Earth and the collapse of ecosystem services." Furthermore, he hopes to dispel "the myth that perpetual pursuit of growth is good for economies or the societies of which they are a part" for the well-being of the planet, of underdeveloped populations, and of the sick, stressed, and overweight populations of overdeveloped countries. Assadourian argues via the principle of plenitude that degrowth will inevitably occur whether we want it to or not because—on a planet of finite resources—economies and populations cannot grow infinitely, and overdeveloped countries are still pursuing more economic growth and overconsuming resources.
