...and we know that modern day arctic eat all organ meats…nothing of the seal is left that can be eaten. Moreover, if people couldn’t sustain themselves on the local (seasonal) foods, I can only guess, that they were forced to migrate…again, to the extent possible. As any survivor story can tell, people can subsist on (at best) sub-optimal food for quite some time.
