The birth of Dolly the sheep in 1997 opened the door to human cloning technology, but ethical, social, and technical issues remain unresolved. Human cloning offers positive possibilities, such as organ transplants and cures for genetic diseases, but it also poses a significant risk of undermining human dignity and causing social conflict. It should be approached cautiously and only after the...
