I don't think one is necessarily connected to the other. Putting aside the wee small technicality of how you'd actually find/scavenge/hunt/snare these animals, when I first read this topic, the James Kim family tragedy flashed through my mind. They had the river next to them for water, the car for shelter, (I forget if they had fire besides burning their tires) but just no food. Any sustenance would've helped them.
