an0n: some good ideas there, but by the time society becomes a really integrated unit like this, science will have progressed far enough so that you can just have your cloning vats generate whatever types of humans are wanted for the whole.

Abortion = murder
Actually, here is another equally true statement:
breaking up a mound of dirt = murder

Modern science is always advancing, and I'm sure that the premature stage at which a baby is born and is able to be kept alive is getting earlier and earlier with new technologies, etc. So does that define when a fetus is considered to be a "real" human - when it's possible to keep them alive, with all modern medicine can do to help, outside the womb? And such an age would have to be constantly redefined as time goes on, of course. Which, to me, makes it total nonsense.
Ah, I think you have caught on here.

Now keep following up this argument further up and see what you get; at some point, humans will probably be able to turn dust into life, so the dust would be life too. The whole thing about life, non-life and whatever else is completely meaningless; everything is alive and and everything is dead.
