I got a prospectus from a socially responsible investment group and this petite parable was printed on their materials:
Thousands of starfish washed ashore. A little girl began throwing them in the water so they wouldn't die.
"Don't bother, dear," her mother said, "it won't make a difference."
The girl stopped for a moment and looked at the starfish in her hand.
"It will make a difference to this one."
