The reality is that the whole "climate crisis" thing is gonna require humanity in general to gang up on the problem from all angles and each contribution will help the overall situation improve to some degree. The sum of all those contributions is the solution.
The longer we keep looking to corporations, politicians, and scientists to come up with a "magic bullet" for the problem, the worse it's gonna be for everyone and the less likely any amount of human efforts will be able to improve it again.
Regarding the various aspects of the unsustainability of our society and how it is reaching its limits, this wiki subsection is a very good read (and the rest of the wiki page as well, separated into concrete sections, and links to lots of source materials):

Some good info at that link. Thank you for that.
(Gonna take me a while to read through it all, but at least it gives me something to do with my time besides just storing up survival resources and stress-levels while I wait for it to happen.)
Collapse of ecology is certainly a problem. The Colorado river is not (for residents). A tiny portion of the population who farms consumes more than all of the residential use combined.
We make farmers pay for the fucking water they use and then the problem is solved. This doesn’t even require a technological breakthrough.
