I recently watched a video taken by naturalist John Walthen, flying over the Gulf of Mexico. There were columns of thick black smoke from oil burned on the surface, through which unwary birds were flying. There were pods of dolphins in the oil; some already dead; some still struggling to live.
There were miles of oil-covered water, in which nothing will survive. Unseen were the subsurface plumes of “disbursed” oil that is sucking all the oxygen from the sea, killing everything in the area.
