This week my guests discuss big problems regarding food. How can we work toward healthy food and enough food for everyone?

Maryn McKenna is a journalist who writes about science, food, and disease. Like Superbug: The Fatal Menace of MRSA. But that's not the end of it. We’ve been pumping antibiotics into chicken for a good long time. They have come home to roost. We can’t make antibiotics faster than evolution. Ms. McKenna and I talk Big Chicken: The Incredible Story of How Antibiotics Created Modern Agriculture and Changed the Way the World Eats.

I also speak with Andrew Fisher of Portland. He is an activist in the anti-hunger field. For twenty-five years he has worked building coalitions to fight for better food and nutrition laws. He is blowing the whistle. Hunger is big business. Andrew is the author of Big Hunger: The Unholy Alliance Between Corporate America and Anti-Hunger Groups.

Finally, I speak with John Teton, author of the International Food Security Treaty (www.treaty.org). This treaty is an international enforceable law requiring all nations to guarantee food to everyone in their borders and not use hunger as a weapon. That would end the wars.
