Each and everyday I become more convinced of this argument.
Well, if you're convinced, then I'm convinced. baa! baa!
The fact is that the natives who lived in the pacific northwest had successful land management practices. They had rules for who could fish where and how much, they set fires yearly when moving between their summer and winter grounds which kept down the brush including poison oak, and they were able to subsist primarily on hunting and gathering because their land management was so very successful and the land so rich. Predictably, ol' whitey fucked it all up for them. First he murdered them wholesale, notably in the form of the U.S. 1st. Cavalry killing every man, woman, and child on an island in the lake (one of the larger settlements) in revenge for deeds by a distinctly different band of Pomo. Then he destroyed their way of life by attrition, granting their land to others and then paying them a dollar per tree planted to rip out the oaks and install black walnut. You can't live on walnuts alone, but you can live on acorns.
The point here is that humans are capable of responsible land management, the problem is which humans are chosen to make the decisions. Baa! Baa!
