This is where I’m at too.
At least as far as I understand it today (leaving this comment in the hope that folks can help me expand my understanding)
Life on earth is not stable. We are in the final death throes of this planet. Roughly 75% of life on earth is behind us. Life has been here for 4Bn years and we have about 500m left[1] until our carbon cycles grind to a halt due to the earth moving outside of the habitable zone and all life on earth starts it’s final, and ultimate, extinction event.
This pending extinction event is not human made. It was coming regardless of whether humans evolved on this planet.
From everything I can tell, there is no making it through, let alone coming back from, this impending extinction event without “technology” that decouples life from the carbon cycles on this planet.
In 4.2bn years life on this planet has printed exactly one golden ticket for escaping that fate: humans.
We’ve done some bad things along the way to industrialization processes that can produce the technology necessary to get life off this rock - and to artificially sustain life on this rock as it becomes unsuitable for life.
But I’m not confident that the bad stuff we have done is sufficient to condemn our species and disqualify us as a suitable steward for this planet. Primarily because there is no alternative, there is no species in “second place” that I’d trust to evolve a civilization capable of getting life off this planet in the time we have left.
The eco-movements (outside of whole earth) have lost me. The calls for an immediate suspension of industrial processes, or the sentiment that life on earth would be better off if humans didn’t evolve to be what we are today, seems misplaced.
Without humans, and without our recent attempts to escape this planet, all life on earth is doomed to complete extinction.
It seems like we are in a critical several hundred year window where humans need to appreciate both that we are accelerating the end of the Holocene, a climate that was critical for the development of our civilizations, and do our best to slow that process already under way.
At the same time, we need to maintain the civilization that’s setting life on earth on an escape trajectory.
If we toss the baby with the bathwater we doom all life on earth to guaranteed extinction.
