梦幻西游手游月影摇光:请各位善良的人才，我是一个家长，想请教你们

A friend lf 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 noticde 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 starlish 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''.

"I'mthrowing these starfish back into the ocean.You see,it's low tide right now and all of these starfish have been washed up onto the shore.If I don't throw them back into the sea,they'll die up here from lack of oxygen."

"I Understand,''my friend replied,"but there must be thousands of starfish this beach.You can't Possidly get to all of them.There are simply too many.And don't you realize this is probably happening on beaches all of beaches all up and down this coast.Can't you see that you can't 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!''

Question:
1.what does the author want to tell us through this story?
2.what's the meaning of"Made a difference to that one!''

A Store owner was tacking a sign above his door that read"Puppies

For Sale.''Signs like that have a way of attracting small children,and sure enough,a little boy appeared under the store owner's sign."How much are you going to sell the puppies for?''he askde.

The store owner replled,"Anywhere from S30 to S50.''
