Next year will mark the 60th anniversary of Shell’s discovery of oil in Nigeria’s Delta region. It could spend the next 30 years–and billions of dollars–cleaning up a devastating environmental mess it’s said to have left in its wake.  Shell Petroleum Development Company this week signed an agreement with Nigeria’s Bodo community to begin clean-up operations of two major oil spills from back in 2008. Dutch newspaper Volkskrant reported (in Dutch) that the estimates for the clean-up costs would be up to $500 million and take ten years... [Shell] had already agreed in January to pay out £55 million ($84 million) in settlements to the Bodo community for the devasting effects of the spill.  But Bodo, home to 40,000 people, is just one of tens of communities in the Delta region devastated by the environmental damage to their livelihoods as farmers and fishermen.
