It isn't a life until it can breathe on it's own outside the womb. Life begins with the first breath taken, if life began earlier your birthday would be the date of conception. Up until the first breath you have the potential to become a person but you aren't one yet until you start to breathe. If you can survive outside the womb, welcome to the world, if not, the child was not meant to be. we are messing with natural selection when science interferes with the normal clearing out of those who were not meant to live. We are an overpopulated planet burdened with caring for those with no useful life purpose.
