The "writing is on the wall". The effects of hundreds of years of human activities that have damaged ecosystems, e.g., over hunting, industrial farming, pollution, now means human cultures are on the brink of a forced change.
The time for choice has been squandered.
But, all species are regulated by ecological limiting factors. It's only human hubris that many people believe that homo sapiens are different
