He may have been an environmentalist, but maybe more so than when he was posing, smiling with thumbs up, in front of the Lear 35 that was being fossil fueled up.
There’s nothing wrong with wanting a generally clean environment. The pollution of the 60s was idiotic. Brown smog constantly over LA, Lake Erie catching on fire, the Chicago River was an open sewer.
He was in for sane environmentalism. The modern environmentalism is a retarded religion.
