That doesn't explain teenagers. My teens and their friends are not aware of that sort of things at all. That is more of a college-student mentality.

Teenagers are sensitive to the cognitive dissonance that accompanies learning how society works and their place in it, even if they're not yet able to articulate those feelings. Some are more precocious than others but anything a college student would be able to tell you about their relationship to society was developing for years beforehand.

I agree with you; however, the interesting thing is that instead of millenials asking boomers why they've gone and strip mined everything, the millenials are mad that there's nothing left to strip mine.
