In Canada the bison, having more brains than politicians and green eyed eco twits, moved southward as their main food source, the prairie grasslands, suffered fifteen years of locust infestation thus denuding the grassland. Admittedly there was some killing of the animals by both the indigenous population and the nasty white man (both French and English) but the dominant reason was no food. Unfortunately both the written and visual media fail to explore the real reasons for the mass migration and perpetuate the myth that the white man was the reason. It never ends.
