Exactly. Native Alaskans changed their lifestyle and what was once a momentary camping areas, became a permanent villages and towns. But before that, they were nomadic people, following the game where ever the animals went...on land or on sea. This change of their lifestyle have NOT gone unnoticed by the native people even although they insist on living a subsistence lifestyle that is really not sustainable in the long run. AFN have always ignored such consequences. Title Wave got many good books on such matter debated from both sides of the fence. You should take a look and see for yourself, what sort of books may appeal to you. There are so many that you just can't ask for a specific book. It like asking the same question about what cause the American Revolution or who was at fault for the south during the Battle of Gettysburg. Subject matter is simply too broad for a single book. Knowledge is not cheap and not easy. Food for thought!
