Life begins at conception. Just simple biology. The single cell of a fertilized egg can reproduce itself, through an admittedly very complex life cycle. It consumes food (it must; is there research on this?). It’s not mobile, but I don’t think that’s an important part of life. Once fertilized, the egg will probably follow a trajectory to become a human being. For this reason, although I’m certainly a social liberal, I don’t think that abortion is the choice I would make. Every person has the right to choose for themselves.
For the same reason, I don’t believe in capital punishment. It is wrong to end a life. Everyone is redeemable.
Finally, we have to get the human population under control. Both crime and over-population need preventative solutions, not ex post facto termination.
