“When Netsilik Eskimos must either undergo a long migration or starve, the number of dogs they can feed limits what they can carry on their sleds and how fast they can travel. If there are old people too infirm to carry their own weight, they cannot be put on a sled at the expense of equipment that is necessary to a family's survival. Generous feelings based on nepotism or altruism must be set aside; these unfortunates are sadly allowed to freeze to death (Balikci 1970).”
