Ah yes, "how we will sustain the species if woman aren't forced to make babies???". Do you listen to yourself at all or is your internal monologue just a constant white noise?It sounds like you don't think a woman should be expected to take responsibility and maintain a life she brings into existence, to any degree. How sustainable is that in reality?
It is very sustainable if you realize that the only abortions are of unwanted pregnancies or pregnancies dangerous to the woman. Plenty woman want to have children even with abortions, and the quality of child rearing increases dramatically if the woman are able to decide when the right time is to raise a baby.
But this just in, the woman will know for herself when the best time to do so is, and thus it should be their choice, not anyone else's.
And no, having sex and then getting pregnant on accident is not an excuse to "take responsibility" by forcing her to bring the embryo to term, it is nobody's business to determine why the pregnancy occured, the service should be offered without interference by government or zealous religious beliefs.
