Why is cloning of mammals controversial?

Cloning of mammals is controversial due to ethical concerns surrounding animal welfare, the potential for suffering in cloned animals, and the implications for biodiversity. Critics argue that cloning can lead to health problems in clones, as seen in cases like Dolly the sheep. Additionally, the prospect of cloning raises moral questions about individuality and the natural processes of reproduction. These concerns are compounded by broader societal implications regarding the manipulation of life and the potential for human cloning.
