As just discussed，cloning can be used to help benefit those that cannot have children through the normal，natural way.It is the desire of most couples to have children and when it is impossible to bear children of their own，some are willing to do anything to have a child.Cloning will allow them to have a child or many children that have the genetic pattern of one of the parents. Through cloning，research can progress.We can learn enough to produce human organs without having to produce human beings.We may develop technology to allow easier genetic testing and fixing problems such as spinal cord injuries，cancer，and many more.
