How ironic that a professor in neighboring Michigan would claim only 1/2 million in the whole world. Make me wonder if he is claiming that number for Michigan alone.

No one knows where Mayda got that figure from, but hey, it was printed and now it's fact. > Moving on ... > Here are four questions I just got that I still don't know how to >easily answer: >(1) Total number of islands in the world >(2) Total number of islands in the South Pacific >(3) Volume of water in the South Pacific >(4) Sea area of the South Pacific > >Any ideas? > >Angie
