Sufficiently comfortable isn't a moving target. People have fixed needs. Sure, we desire to go beyond those needs, but we also desire a living, healthy environment with trees and animals. It's only when we don't meet our fixed needs that we deprioritize our biophilia.

To make this very clear: rich people usually want a big house but they also want a big yard with nice plants. Many of them want it to be somewhat overgrown with "wildflower" beds, native bushes, honey bees and so on.

This process is working itself out right now for fossil fuels. As we become aware of the damage technologies do, we rapidly transition to technologies that do less damage. This change takes generations but it's clearly underway. We also can't expect people who are experiencing privation to prioritize their biophilia over their survival. There's of course a danger in not transitioning fast enough. There's also a danger in transitioning too fast and killing lots of people in the process. Seems to me we're doing fairly well.

I am fairly sure that oil is not continuing to be sold to better the poor.

And these “people” have been knowing about climate change since the 60s, and they deliberately lobbied for the silencing of it.

Regardless, if we stopped burning fossil fuels tomorrow, a lot of people would be miserable and die, and most of them would be poor.
