ABSTRACT
CRISPR/Cas is a genome editing techniques with great innovative potential in plant breeding. It transfers genes mainly within species boundaries. Thus, plants can be similar to the outcome of conventional breeding or their wild relatives. However, a societal debate has come up whether this technique is acceptable for organic farming and whether these cisgenic plants are still genetically modified. Both proponents and opponents argue by referring to the concept of naturalness. This chapter aims to analyse the different understandings of naturalness that lead to different moral judgments about CRISPR/Cas' acceptability and to argue why natural identity is not a sufficient argument to reject all ethical concerns.
