> The idea that natural systems reach an equilibrium is a fiction There's a middle ground. a) We invented modern medicine and now live 2-3x as long as evolution selects for. b) We have effectively no predators. Most apex predators are limited in number based on availability of prey. We figured out how to intensively farm our prey. Therefore there's a very high bar that our population has yet to reach, which is unusual. c) While an equilibrium observable in a short period of time may be rare in nature, over longer periods oscillations in population size correlated with availability of resources are common. d) Since the entire system of our planet is dynamic and has had parameters changing relatively rapidly over our lifetimes (both directly and indirectly mostly caused by us), it would be unexpected to find a static relationship between species populations. Everything is adapting.
