For this second episode (27 minutes) on the Business of Food, Professor Richard Walker discusses the history and continued use of pesticides (the concept of gas chambers was started in the fields of California) and the describes the variety of available fruits and vegetables thanks to the State's melting pot of nationalities.
Dr. Walker continues with the logic of growing rice in the desert (there is none, except that it is a best seller in Japan), the agricultural lobby's inordinate influence in water allocation rights (Governor Jerry Brown’s multi-billion dollar tunnels project) and closes with why the drought has caught so many off guard.
