That reminds of a story I heard about a man who was walking along a beach and came to a stretch of the beach that was covered in starfish. For a while, he enjoyed the beauty of it, but soon realized that they would all die from lack of moisture. And there was nothing he could do to save all of them. After a while, he encountered a man who was picking up the starfish, one by one, and tossing them into the ocean. "Are you crazy?" the first guy asked. "There's nothing you can do to make a real difference." The second fellow picked up another starfish, and tossed it into the ocean. "I just did, for that one," he replied.
