New York Times columnist Nicholas Kristof wrote of the dangers of Bisphenol A, a common chemical in plastics and can liners:

While the evidence isn’t conclusive, it justifies precautions. In my family, we’re cutting down on the use of those plastic containers that contain BPA to store or microwave food, and I’m drinking water out of a metal bottle now. In my reporting around the world, I’ve come to terms with the threats from warlords, bandits and tarantulas. But endocrine disrupting chemicals — they give me the willies.

Kristof isn't the only one who gets the chills at the thought of BPA, a synthetic estrogen linked to reproductive cancers. Nena Baker wrote a book, The Body Toxic: How the Hazardous Chemistry of Everyday Things Threatens Our Health and Well-being, on this very subject, and joined Laura in the studio to discuss what can be done about these frightening chemicals. Noting that neither Republicans nor Democrats want their kids ingesting harmful substances, Baker called for government action. "We can't shop our way out of this problem."
