The PC history of North America says that the natives were living here well in tune with nature, and each other, and everything was fine for millennia until the Europeans showed up and “raped the Earth”.
The mass extinction of all those cuddly mammoths caused by the Native Americans just does not fit into the liberal mythology.
The inner part of the Olympic Peninsula in Washington State was not tread by man until some white Americans did it well into the nineteenth century. The deer and other large mammals there had never seen people and were quite fearless of them. Now imagine two whole continents full of mammals who had never seen people until the natives arrived. Easy pickin’s for that expanding edge of humans who first arrived.
Mammoth - it’s what’s for dinner.
The MÄori arrived sometime before A.D. 1300, and all moa genera were soon driven to extinction by hunting and, to a lesser extent, forest clearance. By about A.D. 1400 almost all moa are generally thought to have become extinct, along with the Haast’s Eagle which had relied on them for food. Recent research using carbon-14 dating of middens strongly suggests that this took less than a hundred years,[39] rather than the period of exploitation lasting several hundred years which had been earlier believed. Moa it was what’s for dinner in New Zealand way before the European arrived.
I don't think hunting a 6 ton animal with a sharpened stick "easy pickins". I am sure the first jab really keyed in the mammoth real quick.
There were other animals of that time period who went extinct also, at least one type of antelope and a long horned bison bit the dust along with the mammoths, IIRC.
