The Eskimos inhabitants one of the coldest regions of this planet and their lifestyle often faces struggles with food and healthcare.
In such extreme conditions, it becomes impossible for the families to take care of old people. Thus, they put the elderly on floats and ship them off to the sea where they die of cold and starvation.
Senilicide (the killing of old people) was never universal among Eskimos. It was common in some parts of their range but more so among the Inuit (Greenland to Northern Alaska) than the Yuit (western and southwestern Alaska). Even among the Inuit, some groups found the custom repugnant.
Where it was practiced, senilicide was rare except during famines. As long as there was enough food to go around, everyone got their share, including the relatively unproductive.
Given that the usual diet consisted of fairly dependable catches of caribou, fish, and sea mammals, many years could pass between episodes of scarcity. Considering the dangers of hunting, the old and infirm who weren’t expected to hunt could outlive a hunter in his prime.
On the other hand, when food did run short, the old and sick were looked upon as drains on the community’s resources. Sometimes they were killed – thrown into the sea, buried alive, locked out in the cold, or starved to death. Far more commonly they were simply abandoned to die.
The victim might be taken out in the wilderness and left there, or the whole village might pick up and move away while the old person slept. If the villagers were unexpectedly restored to prosperity, they might go back to rescue those left behind.
An abandoned person would also be welcomed back as a full member of the community if he could manage to make his way back to the village on his own. But usually, he couldn’t.
