The scale of the pollution is mind-boggling. The government's national oil spill detection and response agency (Nosdra) says that between 1976 and 1996 alone, more than 2.4m barrels contaminated the environment. "Oil spills and the dumping of oil into waterways has been extensive, often poisoning drinking water and destroying vegetation. These incidents have become common due to the lack of laws and enforcement measures within the existing political regime," said a spokesman for Nosdra.
The sense of outrage is widespread. "There are more than 300 spills, major and minor, a year," said Bassey. "It happens all the year round. The whole environment is devastated. The latest revelations highlight the massive difference in the response to oil spills. In Nigeria, both companies and government have come to treat an extraordinary level of oil spills as the norm."
The spokeman for the Stakeholder Democracy Network in Lagos, which works to empower those in communities affected by the oil companies' activities, said: "The response to the spill in the United States should serve as a stiff reminder as to how far spill management in Nigeria has drifted from standards across the world."
The voices of protest point out that the world has overlooked the scale of the environmental impact. Activist Ben Amunwa, of the London-based oil watch group Platform, said: "Deepwater Horizon may have exceed Exxon Valdez, but within a few years in Nigeria offshore spills from four locations dwarfed the scale of the Exxon Valdez disaster many times over. Estimates put spill volumes in the Niger delta among the worst on the planet, but they do not include the crude oil from waste water and gas flares. Companies such as Shell continue to avoid independent monitoring and keep key data secret."
Worse may be to come. One industry insider, who asked not to be named, said: "Major spills are likely to increase in the coming years as the industry strives to extract oil from increasingly remote and difficult terrains. Future supplies will be offshore, deeper and harder to work. When things go wrong, it will be harder to respond."
With Kimerling, a professor of law and policy at the City University of New York and author of Amazon Crude, a book about oil development in Ecuador, said: "Spills, leaks and deliberate discharges are happening in oilfields all over the world and very few people seem to care."
