More Doom for the World's Oceans

Over 500 penguins have washed up dead on the shores of Brazil recently as well as some turtles and a porpoise.  The cause of death appears to be starvation.  These penguins usually feed over a wide area and should be finding huge amounts of food.  I have this horrible feeling this is another sign of the death of life in the oceans of the world.  In 1808 the passenger pigeon numbered in the billions and there were many millions of bison.  By the end of that century there were no passenger pigeons and only a few thousand bison hiding in Yellowstone.  Yes we can obliterate all life in the oceans because we're foolish enough to believe we can't.
