A quick look at the statistics produced by the US National Oceanic and Atmospheric Administration and other bodies seems to bear out his thesis. Of the more than 2,100 miles of threatened coastline, one quarter has been touched by oil and much less has been heavily soiled. As for wildlife, the total number of animals found dead and covered in oil for the whole period is 1,296 birds, 17 sea turtles and three dolphins – that is less than one per cent of the birds killed by the Exxon Valdez spill in 1989. During the same period, 1,675 birds, 82 turtles and 53 dolphins were found dead without any outward signs of oiling.
