It's also multi generational - I guess the younger ones have realised it's so fucked, might as well join em.
No, not in the least because it's not a generational issue, it's a species issue. They have the exact same mindset as their parents.
Have no doubt, when this finally personally impacts them they will be outraged and demanding to know why "nobody" (everyone but themselves) didn't do something to prevent it. You start drilling down and they'll tell you that they didn't think it would be that bad. The bright patch in all of this is that the people who are going to be impacted are just as selfish and egocentric as the people that caused it..
