Actually quite a few of them claimed to eat it, and it is served at potlatch from what I hear, but I think the whale hunting revival was more an assertion of their "limited sovereignity" than it was for environmental concerns. I would consider though that even the Makahs are expected to abide by the limitations imposed by international treaty regulating the taking of whales.

Still, I would much rather see them do it the traditional way, rather than using a big 50 bmg. Apparently they are required to spear the animal from their traditional whaling boat first, then they can shoot it with the 50 to reduce it's suffering and limit the risk of injury to the hunters. Contrary to the old Iron Eyes Cody commercial, not all injuns are environmentally friendly.
