    BP spill: Gulf is primed to heal, but . . .

    Every day, Mother Nature burps another 1,000 barrels of crude into the Gulf of Mexico, along with additional quantities of natural gas. Normally, these hydrocarbons don’t stick around long because local bacteria have evolved to eat them about as fast as they appear. Which is potentially good news, she explained in testimony during a pair of June 9 House subcommittee events on Capitol Hill, because those bugs are now in place to begin chowing down on the oil and gas entering the Gulf from BP's damaged Deepwater Horizon well.
