How did the native american groups of the northern west coast adapt to their environment?

The Native American groups of the northern west coast destroyed all food sources in places they arrived. Then they moved on to other places for search of food.  They basically hunted animals for food and gathered the fruits and nuts to make themselves survive. They also fished in water with spears. Sometimes they hunted large animals like seals and whales. They made canoes out of the wood of trees and also sheltered themselves from weather with the help of animal skins. This way they adapted themselves.

Americans often speak of their country as one of several large regions.  these regions are cultural units rather than governmental units --  formed by history and geography and shaped by the economics, literature and folkways that all the parts of a region share. what makes one region different from another? a region's multicultural heritage as well as distinct demographic characteristics like age and occupation make regions different and special. within several regions, language is used differently and there are strong dialects. there are also differences in outlook and attitude based on geography.
