IMAGE DISTRIBUTED FOR WWF - In this image released on Thursday, August 1, 2013, workers are working on an oil spill in Oloibiri Town, Niger Delta, Nigeria. Devastating oil spills in the Niger Delta over the past five decades will cost $1 billion to rectify and take up to 30 years to clean up, according to a UN report. Today WWF is launching a campaign aimed at protecting Virunga National Park, Democratic Republic of Congo, from oil extraction. WWF believes that in areas prone to conflict and lacking good governance, pollution-free extraction will be dif?cult to guarantee. Environmental impacts from oil extraction could threaten Virunga’s freshwater ecosystems, rich forests and rare wildlife, the WWF-commissioned study found. The park is home to over 3,000 different kinds of animals, including critically endangered mountain gorillas. IMPORTANT NOTE BY WWF - VIRUNGA CAMPAIGN 2013: This image was NOT photographed in Virunga National Park, Democratic Republic of Congo.
