Listened to the the first NPR segment but was not able to listen to the subsequent broadcasts answering people's responses. For me, the issue is not so much about nutritional value. I also don't think that short-term studies focusing on USDA "safe" limits of pesticides and herbicides can say much scientifically about long term cumulative effects or effects on fetuses and very young developing children. I do think it is reasonable to have a very conscious attitude and awareness of the environmental impacts over time of organic vs. inorganic methods of food production. Also think it likely that over time, as the label "organic" is applied to foods based on what they are fertilized or treated with to control weeds and insects, consumers will need to be aware and informed about the difference between organic methods and organic philosophy. A field over-fertilized with sludge from a pig farm waste pond is going to leach as much harmful nitrogen into water resources as is a field over-fertilized products from I E Dupont.
