Isn't it a little disingenious to only present these two things, and not the larger issue that matters more?
I, for one, disagree with the idea that the "buffalo jump" was all that prevalent and had a measurable impact, compared to the whites driving the buffalos to what they are now....
You are claiming that indigenous peoples killed more buffalo than "the whites." If this is true, then you are claiming that the indigenous peoples are the ones that drove the buffalo to near-extinction. I disagree with this assertion.
