Swine flu, bird flu, cancer, parasites, E. Coli...what do they all have in common? Factory farms, says investigative reporter David Kirby. In his new book, Animal Factory, he exposes the deep problems with the factory farming system and how it hurts people and the environment. Kirby joins Laura in studio to talk about the book and what we can do to fix our food supply, and Rick Dove of the Waterkeeper Alliance, explains the effect the farms have had on his home in North Carolina.
