I think the people of the west coast had the easiest life because they have a lot of forests, farms and sea. They could eat lots of kind foods or stay in lots of houses. By the way the weather was usually rainy and still like that. Rainy provides growing up for trees. That’s why the people were very lucky for exploiting the trees. And in these forest a lot of animals had been living. So the people could hunt them to eat.
It is good to be a lot of rains. But how people do agriculture? Vegetables and fruits need sun as well :-)))
