Anyone ever wanted to live with a hunter gathere group and learn bushtucker skills? I have always wanted to to travel to the aborginal communities where some of the old folks still know how to live off the land. You see quite a few bushcrafty types- especially in the US ( youtube is full of them) developing various skills but a lot of it is really the easy end of the spectrum, aka shelter making, tool building, primitive tech, basically 'fashioning stuff'. I do this myself.
The big problem, the elephant in the room, is whether your group can catch, hunt or gather enough calories in a day to live. This is an array of skills including the minute observation of your environment that is an order of magnitude more difficult to learn.
A lot of time, money and public emphasis goes into preserving the the painting, songs, dance etc of primitive cultures but the real lost art is thst which formed most of their day,. A vast array of skills and techniques to pull calories out of their environment
I wish more emphasis would go into it personally by the government, its like losing a branch of science. In practical terms its not something that can be taught in a school classroom or 2 week dance workshop, so its probably destined to completely dissappear.
