Hi Gdenby,
The comments that you can't read backed up what Specter said in his interview.....a bunch of over the top anti technology comments....and a share of very pro technology comments. Easy to argue that both sides have religious zeal.
I don't completely understand your first point about gm crops. Believe that Specter's point is that cultural-based attitudes in the developed world (versus science-based opinions) shouldn't be barriers to the third world accessing technologies that help them feed themselves. He uses combine harvesters as another example.
In regards to Mr. Pollan saying that gm foods don't have a history of increasing yields this is something I know a little bit about, it's a canard, and a strategy that I think is very clever on his part.
Organic foods are criticized primarily for their cost. They cost a lot because they are labor intensive and have lower yields than conventional food production. So, if you are being criticized for low yields, attack the other side for low yields and put them on the defensive.
In truth, yields for all of the row crops -- which is what Pollan is talking about -- have increased incrementally year over year for decades not because of gm technology, but because of really good plant breeding. gm traits are added that facilitate farmers not spraying really bad chemicals or switching from really bad chemicals to more benign chemicals.
The question for the farmer is, "does adding the gm trait reduce the value of the crop: do the input savings (less chemicals used, less fuel, less labor) offset any reduction in output value."
On this subject I think Pollan is more Pat Robertson saying that Haiti was destroyed because years ago they made a pact with the devil, than a well-informed analyst of complex food issues. Farmeres are too cheap to switch to a technology that costs them more money.
On research, Center For Science In The Public Interest issued a paper -- Failure To Yield. Surprise! It said that gm crops haven't increased yields. You can google it and criticisms of the science, or lack thereof, behind it.
And, black and white yield data is at the USDA's web site...including mystifying reports on this year's harvest.
And this exchange supports, I think, Specter's thesis.
