While cloning provides many immediately obvious benefits,it also opens a Pandora box that will destroy social orders as we know it.Human society functions based on succession of generations and on each generation's DNA being different from the previous.With cloning,both of those will be changed forever.Cloning will allow those who can afford to produce fully transplantable organs to replace their aging organs and therefore possibly live to be hundreds of years old.Some may attempt to clone a complete copy of themselves and it means two generations will have exactly the same genetic composition.With line of generations blurred and unique genetic compositions across generations no longer a guarantee,human society as we know it will no longer be possible.And once this Pandora box is opened,it can never be closed again.
