With exception to the herd #'s explosion.....we can still "take it back" to where it was "then" by our choice of equipment. If you're willing to hold out for a certain criteria of animalin your pursuits.....I suppose you could make it as "old school" as you wanted.

As far as technology....shared knowledge....etc....Yeah....we owe them a lot. When/where I gre up.....I'm not sure I could have kept the flame buring, not seeing a single deer in a season, though. When I was growing up....that would have been a very distict possibility/probable likelihood.
