ogoni pollution.jpgThe United Nations Environmental Agency says decades of oil pollution in Nigeria’s Ogoniland Region will require the World’s biggest ever clean-up which could take up to 30 years.

In a report, the agency called for the oil industry and the Nigerian government to contribute US$1 billion dollars to a clean-up fund for the region.

The report further pointed out major health risks in the region of Africa’s largest oil producer due to contaminated drinking water, land, creeks and important ecosystems.

Activists reacted to the report by criticising oil giant, Shell, historically Nigeria’s largest producer.

However, shell responded saying oil theft, sabotage and illegal refining are the main causes of pollution in the Niger delta.

Nigerian President, Goodluck Jonathan said the government will discuss with shell and other oil companies as well as relevant government agencies on a way forward.
