Taseko has a lovely video outlining the plan to preserve the surroundings, specifically Fish Lake.
Member of First Nations communities brought the topic of Sasquatch to the discussion several times. When Former Esdilagh chief Thomas Billyboy said he noticed noticed not only grizzly bears leaving the Cariboo but that sasquatches have been leaving, too. Angelina Stump told the panel that her people's oral history includes a time when animals, including sasquatches, spoke directly with people. Other references were also made, but the general rebuttal was that these claims were either ridiculous or proposed for political purposes.
One opinion piece of the subject suggests that sasquatch is a myth. The author further suggests that
The logic is simple. With no proof that the Sasquatch doesn't exist, it is therefore possible that it might exist and we just haven't proved its existence yet. The faulty logic is easily exposed with another example - we also haven't found one-eyed, one-horned, flying purple people eaters, either.
One thing most reports and articles don't mention is that there is precedence. In the US, the state of Washington, Sasquatch is protected. The US Fish and Wildlife Service lists Bigfoot as an endangered species. Most North American agencies have prohibitions against killing species that are as yet undefined. Specifically, in Lake Champlain, Champy is now protected by law on both sides of the lake. In the early 1980s Port Henry, NY, the State of Vermont, and the New York State Assembly and Senate passed resolutions protecting the "mythological" beast.
While one side proposes that "absence of evidence is not evidence of absence" a la Carl Sagan the other side calls this false logic. They have misinterpreted the meaning to be that the 'absence of evidence might still be proof of existence" and therefore discard the whole idea. In the case of Sasquatch et al, I would suggest that the absence of evidence might be evidence of a need for better research and open-mindedness--especially when proposed against a blatant earth scarring project.
