MILWAUKEE, Wis. – Fresh-water scientist Dan Egan at the University of Wisconsin-Milwaukee has amassed evidence that phosphorous is horribly detrimental to the environment. His new book, “The Devil’s Element: Phosphorous and a World Out of Balance,” documents that agricultural run-off, containing even traces of phosphorous from fertilizer, has spiked epidemic growth of toxic blue-green algae. The run-off is squeezing other life forms from lakes, ponds and streams in “goopy toxic,” he says.

“Devils Element.” New in bookstores Tuesday.
