As he looked down at the beach, he saw a human figuremoving like a dancer. He smiled to himself at the thought that someone woulddance on the beach. So he began to walk faster to catch up. As he got closer, hesaw that it was a young man and the young man wasn’t dancing, but instead he wasreaching down to the shore, picking up something and throwing itinto the ocean. As he got closer, he called out, “Good morning! What are youdoing?’’
Theyoung man paused, looked up and replied, “Throwingstarfishes(海星)in theocean.”

“The sun is up and the tide is going out.And if I don’t throw them in, they’ll die”.
“But, young man, don’t you realize thatthere are miles and miles of beach and starfishes all along it. You can’tpossibly make a difference!”
