لماذا تعتبر الهندسة الوراثية مفيدة جدًا؟

Could you please elaborate on the significance of genetic engineering? Why do we consider it to be such a valuable tool? Could you provide some examples or scenarios where genetic engineering has been particularly beneficial? Is it just in the realm of medical science or does it have wider applications? I'm curious to know how it impacts our daily lives and what potential it holds for the future. Thank you for your insights!
