US women die in childbirth at three times the rate in Britain, due to lack of prenatal care, and government interference with abortion and birth control.

Abortion is considerably safer for the woman than childbirth. Forcing large numbers of poor women to go through childbirth when they wanted an abortion will kill a substantial number of them. But not most of them.

Most of them will begin raising a child they did not want and can't afford to take care of — which is going to cause lots of suffering.
