‘According to the U.S. Environmental Protection Agency...’
I was alive and aware back then. Earth Day was originally concerned with pollution, which was and remains a serious problem for us. (And the E.P.A.was proposed by a Republican president.)
We had never heard the term ‘Global Warming’ back then. As I said previously, we had been told for long while before that a next Ice Age would take us out.
But that concern over pollution has had a lot of good results - see the improvement in the Chesapeake Bay, where all of the grasses were dying in the ‘70s but now are coming back.
It’s one thing to despise current politics. But blaming them on legitimate concerns of 50+ years ago doesn’t make sense.
