It's 2017.  Time to stop relying on killing marine mammals to survive.  Federal and state assistance is drying up.  The climate is warming,  traditional foods are not as abundant and the majority of world in the world do not condone a few people in Alaska killing lots of whales, seals and walruses.  Time to do like your ancestors did.  When it becomes impossible to survive at one location, you pick up, move and adapt.  Soon you won't have any choice but to do this.
