Their looks, style of clothes and the original way of surviving somehow remind me of Tibetan. (Afterwards I found out that they migrated from Asian area to North America for around two generations).
When I got informed that the family pictured died of hunger because the shooting had delayed their hunting for food, my heart saddened and felt a bit complicated. On one hand, this family as a typical demonstration of Eskimo was presented and unveiled worldwide; but on the other, they died because of it. (Their sacrifice is only a little step compared with the bigger step for the whole community?)
There is this line in the film: they are forever on the quest of food. The moment I saw this, it occurred to me the question of meaning of life. Some people are forced to spend their whole life searching for food in order to survive, whilst some others (like us), with abundant, or even superfluous, physical materials to live on, are painstakingly digging out the meaning of life. (Just to display the difference here, not to question)
