Personally, I been upvoting everyone who makes realistic and valid points, even if I don't like what they have to say, because especially in discussions about this particular topic, we need to entertain a wide variety of viewpoints and be willing to accept that not any one magical solution is gonna fix this.
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.
