Cloning stinks.  As is said by the title.  I don't think anything can be gained by recreating life.  Cloning can cause deformities and shorter life.  Clones are more prone to illnesses because their immune systems are weaker.  Almost all clones have died young and have had deformities of some sort.  There have been successful cloning operations but none of them were of any help to humans besides being a pet, or even a pest.  Such as a rat.  Do you think cloning rats is of any use at all?  I don't, and considering all of the mistakes scientists have made, I don't think they'll get any farther.  Enough animals already have tough lives, we don't need to make it any harder.
