"Humans began genetically modifying plants to provide food more than 10,000 years ago."
(This has been well understood ever since the Young Earth Creationism view of the age of the earth was set aside.)
"For the past hundred years or so plant breeders have used radiation and chemicals to speed up the production of genetic changes. This was a genetic shotgun, producing lots of bad changes and a very, very occasional good one."
(One example of this that is very familiar to me is the variety of sweet, pink-fleshed grapefruit grown in Texas, which was developed by irradiating grapefruit seeds.)
"Most early alarms about new technologies fade away as research accumulates without turning up evidence of deleterious effects. This should be happening now because scientists have amassed more than three decades of research on GM biosafety, none of which has surfaced credible evidence that modifying plants by molecular techniques is dangerous. Instead, the anti-GM storm has intensified."
If someone wants to disagree with this aspect of the article, the thing to do would be to cite evidence that there is any danger to GMO technology. As I type this, no one commenting in this thread has yet done so.
"Insect-resistant GM corn also decreases human and animal exposure to mycotoxins, highly toxic and carcinogenic compounds made by fungi. The fungi that produce mycotoxins follow insects into plants; insect-resistant plants have no insect holes for fungi to enter and therefore no mycotoxins."
This is a fact new to me that I learned from the article kindly submitted here. All living things are in biological competition, and most living things are toxic, by natural selection, to some or many of the other living things that might eat them. GMO technology allows human eaters to enjoy safer food.
"Farmers don't have to buy Monsanto seed, nor is anyone preventing them from saving and replanting any seed they want, except for patented seed they've signed an agreement not to save and plant. Farmers buy seeds from Monsanto and other ag-biotech companies because their costs decrease and their profits increase. If they didn't, farmers wouldn't buy them again."
Most of my uncles and cousins are farmers. The quoted statement is true. Farmers buy products if the products offer a good safety and effectiveness profile for sustainable farming. Agricultural products that don't work don't get a lot of repeat business from farmers. The people who are still farmers in the United States feed the entire country they live in and have enough surplus production to feed much of the rest of the world. Farmers in other countries have also enjoyed increased productivity as a result of agricultural research and free enterprise in agricultural products. The whole developed world is seeing rising life expectancies and reduced disease burdens at all ages,

so whatever is new about agricultural practices in the developed world seems to working well so far.
