Therapeutic cloning

Reproductive cloning involves implanting a cloned embryo into a uterus in the hope of producing a healthy foetus. A company called Clonaid claims to have successfully cloned thirteen human babies. They say that all of the babies are healthy and are in various location including Hong Kong, UK, Spain and Brazil. Clonaid states that they are using human cloning to assist infertile couples, homosexual couples and families who have lost a beloved relative.

The same technology can be used for animal cloning. If endangered species such as the giant panda and Sumatran tiger could be cloned, they could be saved from extinction. Livestock such as cows could also be cloned to allow farmers to reproduce cattle that produce the best meat and most milk. This could greatly help developing countries where cows produce significantly less meat and milk.
