A man walked along a beach where thousands of beached starfish lay in the sun, dying. He saw a young boy walking along, grab one, and toss it into the ocean. He continued this. The man, curious, walked up to the young boy, and asked: "Why are you throwing the starfish back in the ocean? It doesn't make a difference - there are still thousands of starfish on the beach." The boy grabbed another starfish and tossed it back into the ocean. "It made a difference to that one."
