Unplugged: Autism Rates and Factory Farming

The first was autism, and, specifically, the debate over the link between autism rates and childhood vaccinations. Guest David Kirby, a journalist and the author of "Evidence Of Harm" and "Animal Factory," told moderator Sharyl Attkisson that it is "astounding," "shocking" and "scandalous" that there is not more of an outcry over statistics that show one in 100 children – and one in 60 boys – will develop an autism spectrum disorder.

The other topic was factory farming. Guest Laura Rogers, Project Director of the Pew Campaign on Human Health and Industrial Farming, discussed overuse of antibiotics on industrial farms.

"Most consumers don't realize that upwards of 70 percent of all antibiotics used in this country are fed, in low doses, to food animals," she said. "And what this does is it creates the perfect situation for antibiotic resistant bacteria to grow and spread into the environment, and it reaches us through our food supply."
