What does it mean for sustainable agriculture?

Fooders, check out this article by Michael Pollan in the New York Times called Farmer in Chief. You don't have to read the entire article (though you are of course encouraged to), I'm asking that you read and comment on the first two sections, through 'How We Got Here'.
Pollen lays out three goals that could turn the food system around. Is one more important than another? Do you agree with these goals? Did anything in the article surprise you? Does it raise any questions? How are you affected by the current system. How does this relate to modeling farms after ecosystems?
Please elaborate on your comments:)
