他们没有农业，但是经过几千年，已经发展了探索自身环境的技术和设备。他们是基于大量出现鲑鱼、大比目鱼和其他多种鱼类的自身流域和水岸捕鱼的经济；基于从落基山水岸聚集了鲍鱼、蚌类、蛤和其他贝壳动物的经济；基于捕猎地域和海洋哺乳动物的经济；以及基于收集野生植物的食物的经济； 10。

Fact; Your baby has a higher chance of being allergic to certain foods more than others, such as peanut butter, peanuts, egg whites, shellfish, fish, and tree nuts like walnuts and cashews.
