A rather beautiful drawing of some penguins standing on ice beneath a blue sky. At the bottom is the label: 'Antarctica, circa 1960'. At the top it says: "Just look at this beautiful, vast, unspoiled habitat we've been born into, with enough fish to eat and ice to live on to last for many thousands of generations to come. Unless, of course, the humans somehow figure out a way to screw up the entire biosphere."
