As more information comes out, it's increasingly clear that GM seed isn't the home run it's portrayed to be. It encourages greater pesticide use, which has a negative impact on the environment and our bodies. And whether or not GM food is safe to eat, it poses a real threat to biodiversity through monopolization of the seed industry and the kind of farming monoculture that inspires.
Meanwhile, a study by the University of Canterbury in England found that non-GM crops in America and Europe are increasing their yields faster than GM crops.
"All this talk about feeding the world, it's really PR," explains Wenonah Hauter, author of Foodopoly and executive director of Food & Water Watch. "The hope is to get into these new markets, force farmers to pay for seed, then start changing the food and eating habits of the developing world."
Since farming is such a timeworn tradition, there's a tendency to take it for granted, and that worries a lot of people. But as much as he hates GM, Bryce Stephens is sanguine.
"I've seen changes since I was little to where it is now," the Kansas farmer says. "I don't think it will last. This land and these people here have gone through cycles of boom and bust. We're just in another cycle, and it will be something different."
Providing we don't break it irreparably first.
