Search around on prepping/survival articles long enough and you'll see all kinds of recommendations for grid down/bug-out food acquisition that are incredibly novel and primitive. There's nothing intrinsically wrong about that either.
However, I do think that one needs to go into such a situation with a realistic mindset. The reason we tell people to start gardening now rather than post-disaster is because there's a learning curve involved, it takes time to master it, and though it's entirely possible to learn things on the fly, Apocalypse World isn't the best place to seek to do so. (That's why it's so important to have supplies on hand – click here to download our free Quickstart Guide to Building a 3-Layer Food Storage Plan.)
These tools may not be the best to rely on in an Apocalypse
The same can be said for some of these food acquisition methods you'll see advocated for out there. While many of them find their place in history as devastating weapons or sources of food procurement for aboriginal peoples, I don't believe they are the best of methods to rely upon in modern day.
Take a look at my reasoning as to why for each:
Throughout history the sling was a devastating weapon in the hands of a trained enemy. Consider David and Goliath. The Roman medical writer Celsus would even state that a stone slung by a sling (say that five times fast) had the ability to penetrate skin and lodge within an enemy's body. Again, the story of David and Goliath shows that as well, as the stone sunk into Goliath's forehead.
