A young boy throwing starfish into the breaking waves :)

An old man walked across a beach until he came across a young boy throwing something into the breaking waves.
Upon closer inspection, the old man could see that the boy was tossing stranded starfish from the sandy beach, back into the ocean.
“What are you doing young man?” He asked.
“If the starfish are still on the beach when the sun rises, they’ll die.” The boy answered.
“That is ridiculous. There are thousands of miles of beach and millions of starfish. It doesn’t matter how many you through in; you can’t make a difference.” The old man said.
“It matters to this one…” the boy said as he threw another starfish into the waves…”and it matters to this one.”
