When we were kids, they told us that a great Ice Age was imminent.
I don’t think it ever became the systematized ‘movement’ that we see now; but it seems that every generation is facing some kind of ‘apocalypse’.
Environmentalists have appropriated a lot of Christian dogma. That a world without people or without the unbelievers of Mother Earth will be a Garden of Eden. And a world that doesn’t repent and submit to the Mother Earth worshipers totalitarian system will suffer famine, plague, pestilence and death. Air turned to ash, the seas to acid and set boiling.
They’re the worst of the religious extremism while denying they’re a religion.
