While CRISPR has opened up new avenues for research and applications, it also raises concerns about ethics and safety. Off-target effects, where unintended parts of the genome are edited, are a major concern. Additionally, the use of CRISPR for human germline editing raises questions about the potential for unintended consequences and the ethics of modifying the human genome.
