Oil spill has gone ? Just be different form

the vast majority of oil from the BP spill has gone ....?

It's just in a dissolved or dispersed form....




"Even if there is not a drop of oil out there, and it had truly magically vanished, it would still be an environmental disaster caused by the toxic shock of the release of 5 m barrels of oil."
