Reuters photographer Akintunde Akinleye recently gained rare access to an illegal oil refinery near the river Nun in Nigeria's oil state of Bayelsa. There, he was able to document the secret and dangerous practice of oil bunkering, where locals hack into oil pipelines, steal the crude oil, and refine or sell it abroad. For over 50 years now, crude oil and natural gas have been extracted from the Niger Delta by large corporations, which have had their share of environmental disasters. The ongoing damage from the tapped pipes and these makeshift refineries continue to take a terrible toll on the environment and the local population. [Refers to Agip, Shell]
