Cloning humans:
pros- less work for an individual, maybe not completely cloning someone so like picking desirable traits in a person and changing that
cons- possible overthrowing of the "real" copy, families who have exact copies of each parent may end in incest, or even selfcest
But we already live in a world where there are real life clones. Twins, and triplets. I believe there's a Brain Games episode that discuss this topic.
