Rather the sin lay in the fact that when Modernity's scientists discovered this not to be the case, they and it did not desist.
Instead human Hubris set about trying to create an alternative artificial simplicity that was predictable and controllable by Man alone : the Triumph of the Will over the Wind.
It was war on two fronts : plenticiding all of Mother Nature's complex unpredictable chaos out of existence and substituting a Man-made synthetic order and simplicity in its place.
From a forever labile thermo-plastic natural reality, it tried to impose an eternally thermo-set artificial reality.
Putting plenticide in writing
Most modernists never had any objections to using Zyklon-B to kill billions of bugs, but they did not want to see it used to kill millions of 'human germs'.
They generally preferred to let 'primitive lives judged unworthy of civilized life', like aboriginals around the world in peacetime and Slavs in wartime, to quietly wither on the vine -- from lack of land resources to feed, clothe, house and heat themselves.
The Nazis could have simply extracted most of the food, fuel and clothing from occupied Poland and Russia for themselves as 'a matter of wartime necessity'.
Then six million Jews in Eastern Europe - or maybe more - might have quietly died in the mix, from hunger-related diseases, along with 30 million of their Slavic neighbours.
After WWII, would have the world have not simply sighed and then speak softly of the cruel necessities of total war ?
But the Nazis killed Modernity stone dead (as well as six million Jews) when they chose to put their plenticidal-genocidal plans in writing.
For they at last made Modernity's always implicit plenticide fully explicit - indicating in writing that they deliberately planned to murder all the world's Jews with Zyklon-B, in an effort to remove a chaos-causing ethnicity from the Earth forever.
Plenticide & the Sixth Extinction
As a result, I don't see today's Sixth Extinction and yesterday's Holocaust as being all that different in their intentions, despite the wide difference in their methods and targets.
As a result of growing up in an transitional Era, we conflicted boomers are both Mo and Po --- practising plenticide semi-consciously on Nature with our actions --- all the while praising diversity and variety with our mouths.
But if we boomers don't start soon walking our talk, the earth & climate is surely doomed ..
