It seems to me we’ve gone from addressing issues with legit medical causes and impacts to addressing those that would surely kill us, given enough time (maybe) but not if we spent enough money and gave up enough of our standard of living. We could run tests to determine eating lead paint chips caused harm. When those issues got resolved, it was on to supposedly bigger and more dire issues because do gooders, once they’ve found a way to make money doing good, still have car payments to make and 2nd homes to buy. We moved from things we could prove to things we could only model and predict. Al Gore showed us the way on this one. He became fabulously wealthy doing it.
