Removing the nucleus from a cell (used in SCNT) is a dangerous process.

Cloning is a fairly new process. It is far from perfected and poses many problems and risks to human life.

Cloning endangered species can allow a population boom in that species and prevent their extinction.

Infertile women are able to have babies through cloning and surrogate mothers.

Extinct species can be brought back into existence. If DNA is preserved, that DNA can be cloned and produce new species through surrogate mothers.

"Pharming" can advance through cloning. Farm animals produce pharmaceuticals. More farm animals, more pharmaceuticals.

Diseased animals can benefit from cloning. In order to fix the problem within diseased animals, animals must go through generations and generations. Cloning can speed up this process and allow scientists to find the problems of diseased animals sooner.
