What are positive and negative aspects of cloning humans? - Answers

A well-known negative aspect is that it is basically necessary to kill one human (by taking out the genetic material from a fertilized egg) to make a clone of another. However, this only applies to current technology; and it is conceivable that other methods are found. A long-term concern is the risk of reducing genetic variety - it is precisely because of the advantage of maintaining genetic variety that sexual reproduction is so successful (most species use it). I believe those disadvantage far outweigh any perceived advantage; but perhaps someone else can give you more information about the positive aspects.
