Quite the contrary. I lived there in the 90-ies. The nature just recovers, and in 3 years humans are forgotten by wildlife. Moose and blackcock will stare at you from a 2 meter distance not recognising the threat anymore. Basically nature swiftly took back what was colonised by humans during centuries of industrial and agricultural activity there in just few years. So the event shows how insignificant humans are.

I would rather say the contrary. You can see "our" significance there, anmials forgetting their most dangerous hunter after not even 3 decades. Thats the difference, a society that can remember.

Unfortunately, the society has no memory as a system. Certain people have.
