what leads to settlement in an extreme environment?

[rYokucHa]

like inuit people did?? i mean, they couldnt get enough vitamins so that they ended up eating guts of animals. and the coldness, nothingness, poorness, monotone life
and what are the benefits of settling in such an living environment?
this is no homework question or anything

it's not a benefit if it's all you have. whatever the surroundings, it's all relative.
