How is America going to end?

In a week-long series for Slate, Josh Levin asks: how is America going to end?

Hurricane Katrina proved that modern America is resilient. It didn’t prove that we’ll be around forever. After watching the place where I grew up avert total annihilation, I can’t help but wonder what course of events will eventually wipe out New Orleans and America as a whole. When it comes to human civilization, entropy conquers all: Rome fell, the Aztecs were conquered, the British Empire withered, and the Soviet Union cracked apart. America may be exceptional, but it’s not supernatural. Our noble experiment, like every other before it, has to end sometime.
