Can Hawaii run out of sand?

Apparently yes. Comments on "Like Sand in an Hour Glass" by Ilima Loomis for the Maui News.

This story took me by surprise. I had never though of the sand on Maui as a precious and limited commodity; I've always just thought that it was there. However, much of Maui's sand is shipped off to Oahu to be used for construction and a large portion of our remaining sand reservoirs are being built over and thus rendered useless. Hopefully, this story has come to light with enough time for Maui to remedy the sand crisis.
