The advantages of human cloning include being able to cure diseases through stem cell therapies, making it easier for infertile couples to have a child and producing individuals who are highly intelligent. However, as there are multiple laws surrounding it, as well as the scientifically challenging aspects of the process, it is questionable whether full cloning can become possible.
Partial human cloning, in the form of stem cell therapies, allows doctors to treat diseases. Stem cells are produced naturally, but can be manipulated to repair the body. There is a chance that scientists can use stem cells to create whole organs, which would make transplants easier.
Although full human cloning is not legal, there are some proposed advantages. Cloning could make it easier for infertile couples to have a baby, as they would not have to rely on using a surrogate or adoption. In addition, manufacturing body tissues and organs that are an exact genetic match for plastic surgery patients would become possible. For example, cloning could result in replacement skin for burns victims.
Some of the more futuristic theoretically advantageous aspects of cloning include producing humans that are very intelligent. However, as cloning humans is not legal, and the success rates of cloning are very low, whether human cloning is possible is questionable.
