Of course, just such a spectacular event did occur in 2010—the BP oil rig Deepwater Horizon exploded in the Gulf of Mexico off the coast of Louisiana. President Obama called it “the worst environmental disaster America has ever faced.” The blowout killed eleven workers and injured seventeen. It ruptured an oil pipe 10,000 feet below the surface of the water, from which oil gushed into the Gulf continuously for three months. The spill released the equivalent of one Exxon Valdez–sized oil spill every three to four days—for 87 days.
