My [slightly older than boomer] mother is terrified at what the future holds for humanity. It literally keeps her up at night. She also smothers her grandkids with love, which I expect is common amongst grandmothers.

My 27 year old nephew, on the other hand, couldn't care less. Well, I mean, he likes to roll coal, but I don't think he's necessarily doing it deliberately to spite the environment, he's just a jerk.
