I base my opinions on the health of the other large omnivore in North America, the Grizzly bear.
We can see that the last 100 years or so, has not been kind to the Grizzly bear. Nor other species such as Wolves, Woodland Caribou, Wolverine, Lynx, Bison, Elk, etc, etc. This is why conservation groups where established at the end of the last century.........it was an attempt to save these species from Extinction. And why Congress passed this act:

Also, once the species is established, we could give it protection under the endangered species act. One species that has thrived under this act is the Wolf.
Sasquatch has no voice...........period. It garners no consideration if a dam is being built, or a shopping mall. It's habitat either is protected by some other species that's needs dovetail to the Sasquatch..............OR they lose.
It's much more dangerous for the Sasquatch to stay hidden than it is for them to be discovered and protected. It's not the guys with rifles poaching them that I worry about, it's the bulldozers and concrete that I worry about.
