It is a different set of conditions. Alaska has less than a million people and is half the size of the lower 48. Most of the people live around anchorage. It seems like there are tremendous numbers of large fish: trout, salmon, char, white fish and shooting a moose, caribou or birds would be kind of easy.
In the winter, I picture that you could be out on a snowmobile gathering firewood or using a boat/atv to get around. You could possibly ice fish as well. Despite that, it seems there could be potential for control using environmental regs etc. Part of me wants to think that there is so much fish and game up there that it's not likely.
The situation for farming or raising food seems different. I'd don't know if having chicken etc is a problem because it's too cold etc.
I found an interesting Alaska forums site:
https://forums.outdoorsdirectory.com/forumHere is someone hauling firewood on a snowmobile. I have to wonder also, how hard or expensive would it be for me to obtain wood from land that I don't own in Alaska ? There is so much forest up there but it's an interesting question
