" Cloning "
Cloning is using genetic engineering to make exact copies of living creatures . since 1997 , with the cloning of " Dolly " , it has become the subject of public debate .
For some people , human cloning is acceptable in medicine despite the criticism that it is unnatural . for example , human tissue can be cloned for use in organ replacement .
When a child is suffering from a fatal disease , his parents can have a younger cloned brother to donate his organ . moreover , couples who can t have children may wish to clone a child from themselves .However many people saw " Dolly " as " playing with nature " . People have no idea of the long-term effects of genetic engineering .
creating perfect plants or animals could eliminate the great variety of species on our plants . Many people find the idea itself repulsive .All things considered , I think that cloning should be regulated for the benefit of humankind , before is too late !
