I was just providing examples of how aboriginal traditional knowledge is actually used outside of what you would call “pristine”. In that instance, there were societies on the west coast that needed an increase of foodstuffs, just like any other society that's growing, and they came up with an innovative process of raised clam beds that were literally kilometres long along the west coast of Vancouver. I think I read that they were pretty much five thousand years old.
There are other incentives when you actually look at the use of corn. Corn is a man-made product and it would not survive without human intervention. That was an invention in the western hemisphere, along with other foods and different other things.
Aboriginal traditional knowledge is also used in the propagation of species like salmon, and a lot of people at the turn of the century criticized aboriginal people heavily for having weirs that shut off the entire river. But if they actually looked at those weirs, they would have found an opening in the middle that actually allowed.... In years when it was recognized that there were lower runs of a particular species, aboriginal people would concentrate on harvesting the male species because with the drift and the milt coming down, it could cover a number of little nests for females and also would not, overall, impact the biodiversity.
Aboriginal traditional knowledge is science-based because it's based upon observation. If you're standing beside a stream for ten thousand years, you must have learned something.
