America woke up to what could be one of the biggest environmental disasters in its history this morning as crude oil from the wrecked BP rig Deepwater Horizon started to wash ashore along Louisiana's Gulf coast.
The 5,000 square kilometre slick threatens to devastate fisheries, wildlife refuges and bird sanctuaries. Louisiana is most at risk, but Mississippi, Alabama and Florida are also in danger.
