One small positive that may come out of the Deepwater Horizon spill is the slender beam of reflected light cast on the fascinating, tragic story of oil drilling in the Niger Delta.

On Sunday The Observer rather stunningly announced that "more oil is spilled from the Delta's network of terminals, pipes, pumping stations and oil platforms every year than has been lost in the Gulf of Mexico". Given the scale and longevity of the disaster in Nigeria the disparity in publicity is troubling.
