I don’t argue that it happened the same way. Impact sure took longer than what we can achieve with modern technology, but the fact remains. Humans arrived into the last jungles of Pangea, and by the time of European colonisation, Australia was a Red Continent, with Eucalyptus being the dominant large plant.

There seems to be a strong indication that human activity contributed significantly to the climate change in Australia.

Not belittling the choices humans make to opt-out of the modern civilisation, but romanticising and mythologising “closeness to nature” just isn’t productive. Profound effect on the environment is a feature of all life forms, and sustainability isn’t really on any life form’s agenda.

Who’s to say that Cyanobacteria aren’t “close to nature”? Yet buggers were so successful, and polluted atmosphere with oxygen so badly, nearly all life went extinct. Even that worked quite well in the end.
