A man was strolling along the beach, waves gently lapping at his feet, the sound of the ocean in his ears. As he walked he saw in the distance the most beautiful colours lining the sand. Approaching closer he found the colours were actually tiny starfish - hundreds of them washed up and stranded on the beached, slowly baking in the sun.

In the middle of the starfish was a gentleman frantically picking up each little urchin and tossing them into the water, one, two, ten starfish; hardly making a dent in the hundreds.

'Why are you putting yourself through it?' Asked the walker 'There's so many, it wont make any difference.

'Really?' Said the gentleman tossing yet another starfish safely into the sea 'It made a difference to that one'.
