So possible, yes. Probable, maybe not.
For all the Hippie nostalgia about ancient aboriginal cultures and their harmony with nature, I can give you scores of examples about how they were notoriously inefficient and wasteful.
Two more examples with suffice.
First: If you are familiar with the winter count histories of the Lakota (Sioux) tribe which I studied in a former life with a grizzled old Sioux, you will know that the tribal elders were often ignored when the young bucks went on a buffalo hunt. If the herd was deemed surplus, the young warriors would often drive far more than necessary over a cliff, harvest what they needed for the winter and leave the rest of the carcasses to rot.
Second example: Before about 1250, the Aztec were content to enslave their prisoners of war and conquered tribes to maintain their lavish cities, building projects and lifestyles. Once they perceived their population to be surplus, they sacrificed them in ever more bloody and gruesome ceremonies because they came to so enjoy the orgy of violence. At the half week dedication of their rebuilt Templor Mayor in 1487, some 1,000 captives per DAY were cut open to the extent that the steps of that great pyramid were stained with blood and the moat surrounding it could not even contain it all. Within a generation, they were so short of laborers and defenders that a relative handful of Spanish soldiers organized the few survivors of the descendants of slaves and human sacrifices to utterly destroy their great city with only token opposition.
Interesting stuff. My grandfather lived most of his life in Dakota Terr., then Montana and Wyoming.
Worked in Cody’s Wild West Show. Wore a copper bracelet given to him by an Indian friend. Did not marry until age. 40.
My father, his younger son, taught us to catch or shoot only what you could eat.
That was the respectful way of the frontier in America.
That was a long time before the environmental movement in this country. Back in the day it was called conservation, a relative of conservatism.
