This paper explores the international controversy over genetically modified organisms (GMOs). We argue that the uncommonly high levels of opposition to genetically modified food in both the United States and in Europe can be attributed to the overwhelming success of the online visual campaign against GMOs. By exploiting the unique characteristics of the internet to create memetic images that can travel freely across linguistic and cultural borders, opponents of the technology have been able to refute rationalist claims about the safety of GMOs. In response to the single coherent narrative of scientific certainty, a diffuse set of challenges emerges. The risk of genetic engineering holds within it the potential for catastrophe, leaving the industries that produce and manufacture the technology in a perpetual state of crisis. Instead of a unified narrative of scientific certainty, each challenge presents a multiplicity of diffuse narratives that unsettle the public's understanding of the risk presented by GMOs. We aim to augment traditional understandings of the way that publics may interact with the "public screen" by explicating one way in which dominance of the visual in mediated political discourse may privilege non-rational political decision making.
