Along the shore of the Allegheny River in Pittsburgh a little girl of about seven, dressed in a track suit threw chunks of bread to nearby ducks and geese. The geese, twice the size of their mallard brethren, aggressively pushed between the ducks to gobble up each morsel. The girl placed her hands on her hips and scolded the winged despots for their greed. A few of the ducks joined in the protest, and quacked in solidarity, for justice. The geese remained undeterred in their conquest. Clearly frustrated, the little girl gave up. She handed the bag of bread to her mother and then ran off to join a group of older children playing frisbee in a nearby grass field. The ruling geese and the victimized ducks continued to swim near the shore, hungry and confused, and without that reliable food source.
