I think that's a side effect of the modern expectation that everyone move cross country on a dime if it makes sense economically. Kinda hard to figure out ecological best practices when families can barely stick around for a generation and people constantly move into areas they're just not familiar or comfortable with.
It takes a long time for best practices to become accepted and normal, and there just isn't the geneological inertia to develop that anymore
I think it predated that in that it occured with even slow "colonization" (regardless of it being occupied or not) but that is a good point. Expectations shape it first.
