Did nature clean up most of the Exxon Valdez oil spill?

Thanks, Cecil.  I don't care what Rush Limbaugh says, you're my hero.

... Do oil spills mostly go away on their own? Yes. Does that mean we’re better off leaving them alone? Of course not. Nobody doubts we need to plug leaks and contain spillage, and I’m persuaded bioremediation helps at least sometimes.
