2012: The Last Jobs On Earth

When the Mayans devised their calendar ending in 2012 more than 5,000 years ago, I bet they had no idea how much end-of-world fodder they were providing for centuries of civilizations to come.

With the date creeping closer and a big Hollywood blockbuster imagining exactly how it would all go down, it's only fair to help plan for the worst - by pondering which jobs would be essential should a small group of us survive the apocalypse.

Keep in mind - this is by no way scientific - I have no research, experience or knowledge to back up these claims. Just a hunch. Feel free to add your thoughts in the comments.
