Answer:
In the southwest, several cultural traditions have been formed related to the intensive use of plant resources. First of all, such complexes developed in the most arid eastern regions of the Great Basin, where an economic system based on the collection of edible plants arose in the early Holocene. Here, for the first time throughout North America in 8-7 millennia BC, stone grater appeared.
In the northwest, people were mainly engaged in hunting and fishing. Due to the harsher climate, many tribes had neither agriculture nor livestock farming. The only tame animal was the dog that was used on the hunt. The Indians of the north-west coast developed an exchange. Dry fish, crushed into powder, fish oil and furs were exchanged for products made of cedar, for the tips of spears and arrows, as well as for various jewelry made of bone and stone. Prisoners of war slaves were also exchanged. The presence of slavery was a characteristic feature of the social system of these tribes.
