No, but the philosophical implications of the "pro-life" (I hate bumper sticker slogans) movement are that abortion revokes a life, or at least a potential one, which can also be said about masturbation. The only difference is that the former involves a heart, which biologically doesn't really mean anything. Arguing that a heart constitutes a life is nothing more than a weak emotional appeal. Hypothetically, lets say you choose not to abort because for that reason, and the child is born into an unfit environment. The child's existence will be a burdon upon society by contributing to overpopulation, and unless its lucky, will be raised in less-than-optimal or even abusive environments. But hey, as long as the kid has a heartbeat, its conscious suffering doesn't matter, right?
You may have noticed my claim that birth is irresponsible, and in the grand scheme, it really is. A "fit" birth is more readily accepted because the marginal benefit of raising a child are justified by the marginal cost of bringing another human into existence. With unwanted children, the cost isn't justified.
