Given the level of anti-Americanism in the world, given the level of frustration with the United States throughout the Muslim world, you've got a homegrown attack or you have a nuclear explosion in the air that is not a test somewhere. Those are still the biggest threats out there.

I doubt very much that the chief executives of any of the Fortune 500 corporations can name five edible plants, five native grasses, or five migratory birds within walking distance of their homes, or name the soil series upon which their house sits. And I would contend that if you don't know where you are, you are in fact nowhere at all.
