The "end of the world" could be a local phenomenon. I like my headcanon that in Mad Max it's just Australia that's fucked, the rest of the world is fine.

If there are functional societies elsewhere in the world, then help in the form of food could be on its way. The question is, will it be distributed efficiently to the people who need it? Something like Food Not Bombs could respond quite effectively to such a situation.
