Oil spills
The amount of oil spilled is miniscule compared to the amount of oil transported each and every day, according to the Mineral Management Service. The figure is estimated at about 0.001 percent. Further, the National Research Council points out that much oil seeps naturally into the sea from offshore oil reserves, even without human interference. The NRC estimates that approximately half of all oil found in the world’s oceans arises from natural processes. Oil spills account for about 12 percent.
