Yep, it's pretty amazing how much not destroying the environment helps it recover... although the closer we get to a collapse, the more that ability to bounce back diminishes
Literally every aspect of our world is in a balance... Everything wears down over time, so the current state is basically a homeostasis between biological, geological, and astrological forces. The problem is that humans act on a far shorter time scale - 100 humans could cut down trees faster than a forest can regrow, 8 billion can change the atmospheric composition in a decade or two
