I have a theory about this, I gave it a name at one point but forgot what I called it. And I think it relates to the idea in the Declaration of Independence where it says "people are disposed to suffer while evils are sufferable". A generation experiences pain (like Cuyahoga, the river-on-fire), acid rain, ozone holes, etc... Struggle happens politically solutions help resolve some of the worst effects (if not outright), and people forget there was a problem. "Why do we have these laws, this isn't even an issue" (this is for things that are obvious, not long term difficult to explain CO2 rise that people don't see easily (or explain away with industry provided excuses). So we get a new generation falling for the corporate line because they don't see a problem, and ... yeah. It doesn't even have to be a "solved" problem, just that it appears to be solved or mostly solved. Or people accept a new equilibrium, which is also the sad part.
