On the other hand, I could starve to death while standing in the middle of a wheat, corn, alfalfa, cotton, or soybean field in Kansas ......
I assume there is food there someplace, somewhere on those plants, but how you turn it into calories is beyond my pay grade .... Carrots, squash, beans, pumpkins, or apples L could probably manage. Those are kind of lumpy.
Wheat and other grain crops have seed heads on the top of the plant that you harvest and grind-soybeans have to be processed for human consumption, cotton isn’t for humans to eat, and alfalfa is dessert for horses, and makes nice tea.
The only item in that list I ever grow is plain old corn, and picking, shucking and cooking that is way easy...
