As for the original In a Nutshell video, it has a few flaws and perspective distortions that taint the quality of the video that was noted and explored by other researching YouTubers. I'd say it's too optimistic that companies and out of control capitalism like it is now will save us.
What makes me sad is that so many companies now are doing token green stuff on the surface that when researched deeper has no positive effect. There's too much dishonest pandering (like with other social groups and situations that need help and aren't receiving the help they need) which ironically not only does it not do anything impactfully good, it also causes the more conservatives to be even more skeptical about green policy. They lump all possible policies together, from the ineffectual company pandering to token gestures by local governments to even possibly true impactful changes on the state level, and therefore think it's all a scam.
What's sad in my part of the world where I'm living right now, especially a lot of people from 45 and older would rather believe that the worsening climate and more frequent natural disasters are cause the WEST (mostly the USA) are controlling the weather and doing these things on purpose...
Completely ignoring the fact that all across the world we're having worse and worse weather, even USA with crazy hurricanes on the coasts, earthquakes, Texas had that freak snowstorm, wildfires, and the tornados in the central region. To me, it's sad what some people will believe. And so they'll ignore the problems and the corruption between megacompanies and countries that made this situation the way it is during their own lifetime.
