How can benefits from embryonic stem cell extraction outweigh its moral costs?:
Since stem cells are abundant in the blood remaining in the umbilical cord after delivery, there does not need to be a moral trade off... I favour harvesting of stem cells from donated cord blood and see no reason at all why embryonic cells are needed at all in order to do the research that holds such incredible promise.


Added after reading the answer below...WOW! Now, this is interesting...I am pro choice and the person below is clearly not, and yet on this issue we are in agreement... If a "Pro Lifer" and a "Pro Choice Advocate" are both saying, in essence, "Hey, you don't need to create embroyos for this purpose, there is another perfectly viable source of stem cells, use it." we have to be right, because usually we probably wouldn't be able to agree that water is wet.
