My sister was in class and in one of her class her professor talked about penguins and oil spills. I'm sure you all know about the terrible effects of oil spills on birds. Basically the oil covers their feathers and the oil destroys their natural oils which makes them very cold. Also, the penguins will try and clean themselves and end up ingesting the oil and poisoning them. What is the solution? Penguin Sweaters! Which also happen to be insanely cute. They keep the wee penguins warm, in style, and inhibit them from preening.
