You may have heard that phrase “we have met the enemy and he is us!” It’s attributable to a character named Pogo. Given the phrase, you might think Pogo was some type of military commander. In fact, he was a cartoon character in a comic strip of the same name. He and a friend were commenting on the natural beauty of a forest but were distressed by the litter discarded there by visitors. Thus, the phrase. Human beings had detracted from the natural beauty of the forest by throwing litter everywhere.
