Role of Genome Editing in Biosecurity and Biosafety","Genome editing is important in the field of biosafety because it has the potential to address several biosafety concerns related to genetically modified organisms (GMOs) and biotechnology. \n\nOne of the primary concerns with GMOs is their potential to crossbreed with wild relatives and transfer modified genes into the environment, possibly leading to unintended ecological consequences.
