Although as far as we know, human cloning has not yet been attempted; there are several different reasons why society might want to use this new science. First a quick definition of the three types of cloning; embryo cloning, adult DNA cloning and therapeutic cloning. Then a whole list of possible reasons that people might embrace this new advancement and some of the downsides to these reasons.
First off, we have embryo cloning, which is a technique that produces twins or triplets. This procedure involves the removal of one or more cells from a fertilized embryo, which are then encouraged to develop into one or more duplicate embryos. The end result of the procedure will have identical DNA (http://www.religioustolerance.org). This procedure has been done on various other species, but never on humans as far as we know. People who would like to have a large family or who have trouble conceiving children might want to use this technique.
Adult DNA Cloning, which is also known as cell nuclear replacement, somatic cell nuclear transfer or reproductive cloning is used to produce a duplicate of an existing animal, for example Dolly the sheep. In this process, the DNA is removed from an ovum and replaced with the DNA from a cell removed from an adult animal. Then the fertilized ovum, called a pre-embryo is implanted in a womb and allowed to develop into a new animal (http://www.religioustolerance.org). This procedure has never been done on humans as far as what has been documented.
Therapeutic cloning starts out the same as Adult DNA cloning; the difference is the fact that the stem cells are removed from the pre-embryo with the result of producing a whole organ or tissue for transplant back into the DNA donor (http://www.religioustolerance.org)

There are several reasons why humans might want to make cloning a part of their everyday lives, and some of the reasons are selfish. We ca...
