Scientist’s might have the ability to save endangered species through cloning which will help the biodiversity of any ecosystem which is vital to its health. Ex.) Panda Bears
Cloning could also be used to reverse the aging process. Over time cells are unable to repair and reproduce. The gradual decay and degeneration of the body that appear with aging is particularly due to this factor. Reversing the effects of aging can be done by substituting the damaged and worn-out cells in the body with newly cloned young cells of identical genetic composition as that of the individual in whom the replacement is being carried out. This process is a theory which if holds true in the future will dramatically increase the length that humans can live.
Researchers will eventually be able to engineer medicine using stem cells that can be altered by cloning.
Cloning could also be used in reproduction for couples that are infertile.
One consequence of cloning would be a reduction in biodiversity and genetic variation. If too many identical copies of the same individual are reproduced, there would be a lesser amount of individuals with unique and useful genomes. This loss of biodiversity could be detrimental especially when environmental conditions change, favoring a genotype that no longer exists.
Beauty in humanity lies in the differences we see in each other. Cloning of humans would eliminate surprise and predict expectancy.
The technology is not well developed currently. The chances of fatality and deformity are higher than that of a traditional birth(Ex. Dolly-277 Tries).
Scientists have cloned a whole sheep, named Dolly in 1997, from nothing but a nuclei from a donor sheep.
