GMO crops can affect more than the fields where they are planted. In Mexico, researchers found GMO DNA in local corn, showing how pollen can move between crops and raise concerns about gene flow, cross-pollination, and the genetic diversity of traditional varieties.
The excerpt also examines the wider pressures surrounding genetically modified agriculture, from glyphosate and its cancer-risk assessment to Monsanto, seed patents, and the limits of controlling patented traits once they move through the environment. The central question is ecological as much as technological: what happens when engineered genes spread beyond the crops they were designed for?
