I used to love watching “Survivorman” with Les Stroud. He made it very clear in his episodes (surviving 7 days alone) that it was very difficult to hunt and kill something, and one’s time is better spent harvesting the easy stuff.
Of course it depends on the climate and location. Trying to live off of plant life in a northern forest is a lot different than South America.
hunter gatherers in russia during the paleolithic made their homes out of mammoth bones.
They probably ate the meat first.
