TreeHugger had an extremely disturbing piece on mass penguin deaths occurring year after year off the coast of Argentina recently. Every year, hundreds or thousands of penguins wash up on the shores of Argentina covered in oil. Most of the time, no one seems to have a clue as to how they got covered in oil. The only guesses people venture (often biologists) is that there was an oil spill somewhere.
But where? And why every single year?
