I don't remember. India comes to mind, but not very clear. Just remember reading in some thread on Monsanto a couple of years back that some country had a lot of farmers ruining their farmland switching from the native crops to the Monsanto sponsored, backed-by-western-"science" soy and corn.
My wife tells me that American grown corn (and, to some extent, peanuts) have a high bar to entry in the Japanese market due to fungus problems derived in part from the climate, but seriously aggravated by the mass farming techniques.
I'll acknowledge that there are a lot people in America who are convinced that the import barriers are just excuses for protecting the local economy, but we don't really have much of local production for the imported corn and peanuts to compete with. So you'd have to argue that their protecting the rice farmers, and that just doesn't hold water for a lot of reasons.
As far as the original issue, I am acquainted with a person who was diagnosed with terminal, as in she was given less than a week to live, cancer, but was brought back with some emergency surgery and a "natural," "organic" food. And maybe some attention and good-old-fashioned TLC. But the organic food was all she could eat, and it was all she could do to eat it.
She couldn't eat the other stuff and keep it down. She claimed it was the processed or petroleum-based fertilizers, the insecticides, the processing.
To you, yeah, anecdote. To me, well, the guy who was taking care of her did experiment a bit, and it was not just a matter of what she thought she was eating.
I saw that happen, I can't argue with it.
You didn't, you can, but I'm telling you, you should not be so sure.
