it was unthinkable in the original Aristotelean framework. They had no notion of being capable of destroying the environment in the way that we can now.
I don't think that's true at all. They could have easily over-fished, exhausted the land through improper farming, or cut down all the trees in a particular area. And they had a very good idea that they could do this and screw over future generations.
I don’t think that model takes ignorance into account. You would be unhappy if you knew you were doing a disservice to future generations, but you might accidentally do something stupid that screws things up for generations to come.
That sounds intuitively plausible; Aristotle's systems in general tended to be bad about modeling human ignorance.
