What’s the essence re: “unsustainability”?

It’s problematic when a population finds itself in an unecological situation where there’s a lack of predation and an abundance of nutrition. The result is a population bloom. Such never ends well.

Population bloom has characterized the human condition for thousands of years. The population bloom may have been the primary motivator of our turn toward developmentalism five thousand years ago. Anthropologists debate issues like that, but, whatever caused the radical transition of lifeways, developmentalism has ever since compounded our problem. It set in motion accelerating civilizational trajectories in regard to:
. consumption
. production
. exploitation
. pollution
. depletion
. congestion
And corollary phenomena such as increasing greenhouse gas emissions, deforestation, desertification, loss of biodiversity, etc.

For 99% of our species existence there was no such thing as “progressive development.” Lifeways were cyclical.

The population bloom and over-development have surely led us to a state of overshoot. It’s unsustainable.
