Last week, I saw Stephen Petranek give an interesting talk in the Technology, Entertainment, Design conferences. It was from a presentation he gave in 2002, titled 10 ways the world could end. He takes a rational, scientific look at ten of the most underestimated threats humanity faces and proposes solutions for each.

One thing that was particularly interesting about Petranek’s solutions is that he suggested just 2% of the current anti-terrorism/homeland security budget to deal with these largely ignored threats. I’m not sure I agree with all of his solutions, but the material was thought-provoking.
