In less than a decade, this industrially efficient slaughter had largely destroyed the Yupiks’ primary source of food and the seasonal hunting life upon which it was based.

Here, as there, the wholesale slaughter of a people’s staple prey had led, in a few short years, to ruinous dislocations, terrible dependencies—and a cultural apocalypse.
