"Sufficiently comfortable" is a moving target.
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.
And these “people” have been knowing about climate change since the 60s, and they deliberately lobbied for the silencing of it.
We already have a built-in solution for this problem: biophilia. People like nature. Once we stop being poor, preserving nature, living in natural environments with trees and animals becomes a high priority. The people "cutting down the rain forest" will stop once they're sufficiently comfortable to prioritize nature over avoiding privation just like the Europeans stopped.
We used to built boats out of wood, now we build them out of metal. There's no reason we can't replace technologies that conflict with our biophilia with those that don't.
