To prohibit abortions does not stop them. When women feel it is absolutely necessary, they will choose to have abortions, even in secret, without medical care, in dangerous circumstances. In the two decades before abortion was legal in the U.S., it's been estimated that nearly a million women per year sought out illegal abortions. Tens of thousands were mutilated. All were forced to behave as if they were criminals.
Legal abortions protect women's health.
Legal abortion not only protects women's lives, it also protects their health. Before legal abortion, such women's choices were limited to dangerous illegal abortion or dangerous childbirth. A woman is more than a fetus. On this question there is a tremendous spectrum of religious, philosophical, scientific, and medical opinion. It's been argued for centuries.
