There was a man who was walking along a sandy beach where thousands of
starfish had been washed up on the shore. He noticed a boy picking up
starfish one by one and throwing them back into the ocean. The man observed
the boy for a few minutes and then asked what he was doing. The boy replied
that he was returning the starfish to the sea, otherwise they would die.
The man asked how saving a few, when so many were doomed, would make any
difference whatsoever? The boy picked up a starfish and threw it back into
the ocean and said, "Made a difference to that one..."
