Hello!

Often in Alaska people have to forage their own food and water unless you live by small little towns. So if you live far away from people then you have to go to streams grab the water and purify it so you won't get sick and die. This goes with polar bears to, polar bears can't just walk into a store and by something. The also have to go to rivers and streams to drink from.

Hope it helps!
