Kerry on the Neuse

U.S. Sen. John Kerry attacks pollution caused by hog farms in North Carolina in a 2007 book.

In the excerpt below from "This Moment on Earth," the 2004 Democratic presidential candidate and his wife, Teresa Heinz Kerry, describe the effects of pollution in the Neuse River on gillnetter Rick Dove in the early 1990s.

"The next year, more fish were developing the bleeding lesions, and Rick's health also worsened. Frustrated and disappointed, he knew he was too sick to keep going. He stopped fishing and gave up his business," the two write.

The health problems, the Kerrys write, were caused by Pfiesteria piscidia, a toxic microorganism that grows in hog sewage.

Dove later became a Neuse Riverkeeper.
