New Breeding Techniques such as CRISPR-Cas9 are revolutionizing plant breeding and food production. Experts believe that the social debate about these technologies could be similar to those on green genetic engineering: emotional and highly controversial. Future debate about Genome Editing could benefit from a better understanding of the GMO (genetically modified organism) controversy. Against this background, this paper (a) presents results of a content analysis of position papers criticizing green genetic engineering in Germany. In particular, (b) it focuses on the (...) controversy as a place where normative concepts of nature are debated and become visible. Hence, the study complements existing interpretations by showing that the emerging concepts are more diverse than the familiar reductionist breakdown of the debate into anthropocentric vs. non-anthropocentric conceptions suggests.
