I feel the same way about all animals unnecessarily slaughtered. "If slaughterhouses had glass walls, everyone would be vegetarian."  I would take it further and say that if dairy farms had (metaphorical) glass walls , everyone would be vegan.
It's tragic what is happening to the Bison, but it's not significantly different than what happened to most people's meals.
In recent years I came to the conclusion that this statement is true for the majority of us.
It takes an interested mind to put all that in perspective. Whether or not you do that has nothing to do with where you live or what you do (well, maybe some agritech types have this in their job description).
If you think "I'm not in the US what do I care." I would argue the one thing the US is still the best at is spreading our business culture and practices around the world. If our practices aren't in your part of the world I expect they will be before long < 20 years.
No idea who said it originally, but a unique English Lit teacher was fond of repeating it. No idea if it was his own thought.
The fight now seems to be focused on getting the bison classified as an endangered species: https://www.nationalparkstraveler.org/2019/09/fish-and-wildl...
>> Of the estimated 5,000 bison in the park in February, only a few hundred had roamed into Montana, and most of these had already been killed. The goal during 2015 was to "cull," in the language of wildlife management, at least 900 of the creatures, almost 20 percent of the herd. Park Service officials told me that the IBMP had established a maximum population of 3,000 bison in the park, and that this year's cull was a first step toward achieving that number. James Bailey, a retired professor of wildlife biology at Colorado State University and author of the 2013 book American Plains Bison: Rewilding an Icon, told me the ceiling of 3,000 animals is "a political number, not a biological or ecological number. It's what the ranchers will accept.
Though as the uncle comment notes, it doesn't really seem "completely justified" here.
I really wish they could figure out a way to let them roam off of the park lands.
Your comment seems impossible, as we have no way to "bring back" those extinct species, unlike bison which do exist.
Your comment seems to imply that we should kill off all present-day wild lions and tigers and other carnivores which may threaten people - something I strongly disagree with.
Your comment places undue focus on current Native Americans, rather than the shared history of species extinction caused by humanity in general, including the aurochs and woolly mammoth, to give but two popular examples - and ones with attempts at bringing those species back.
