We have the technology for editing specific parts of the human genum, specific genes. There are certain scientists who say it's a very good thing. We can now have crops that are more s that give us certain kinds of vitements wewoul would typically not have. And there are scientists who believe this is a great thing. I belive theres sant, it's very dangerous. Why do i say this? It's because we don't understand the genum or any other genum. The entire genum is interrelated.
