I'm not sure if you're being serious here.

What happened to "the ecosystems" when we went from millions of humans to billions is the extinction of many species, and disappearance of biodiversity in general :

> In absolute terms, the planet has lost 58% of its biodiversity since 1970 according to a 2016 study by the World Wildlife Fund. [0]

The ecosystems are definitely not 'perfectly fine' if we keep messing with them [1]

If you want something less dry than pure numbers, you can check the docuserie "Our Planet" on Netflix
