A friend of ours was walking down a deserted Mexican beach at sunset. As he walked along, he began to see another man in the distance. As he grew nearer, he noticed that the local native kept leaning down, picking something up and throwing it out into the water. Time and again he kept hurling things out into the ocean.

As our friend approached even closer, he noticed that man was picking up starfish that had been washed up on the beach and, one at a time, he was throwing them back into the water.

Our friend was puzzled. He approached the man and said, Good evening, friend. I was wondering what you are doing.

m throwing these starfish back into the ocean. You see, its low tide right now and all of these starfish have been washed up onto the shore. If I dont throw them back into the sea, theyll die up here from lack of oxygen.

I understand, my friend replied, but there must be thousands of starfish on this beach. You cant possibly get to all of them. There are simply too many. And dont you realize this is probably happening on beaches all of beaches all up and down this coast. Cant you see that you cant possibly make a difference?

The local native smiled, bent down and picked up yet another starfish, and as he threw it back into the sea, he replied, Made a difference to that one!
