Pity I can't watch the video at this location.
Typically, the Overton window overlooks "saving the planet", but what those folks really mean is 'saving humanity' even as they work desperately to tear it down and make it less humane.
The planet doesn't need saving.
It will continue, with or without humans, barring a catastrophic celestial event.
As for humans "saving" the planet, unless they can detect and avoid such an impending collision, humans have no say in it.
Really. The planet has been inhospitable for humans during most of its history, either due to geochemistry, atmospheric chemistry, or just plain hostile physical environments reflected in thousands of feet of strata that tell of their depositional environments. But the planet kept on existing. Of the critters that have inhabited it, some 99% have died out at one time or another.
How bloody egotistical that humans think they can make that historical pattern any different (especially by discarding the technology that would give them any ability to do anything about much of anything--including colonizing other planets).
But if it makes you feel more secure, go ahead and give your money to the people who claim they will stop a dynamic system 4.6 Billion years in the making, and keep the temperature the same.
I'll save mine for the games at the County Fair, because no matter how difficult, they can be won.
