Both human embryos and human fetuses are unborn human beings that are separate from their mothers, and as such have a right to life under the natural moral law. What makes a human fetus or a human embryo a separate human being from his or her mother is the fact that he or she has an unique genetic makeup that is distinct from his or her mother, the fact that he or she will usually develop into a fully formed human being that is capable of survival outside of his or her mother’s body if he or she is not killed prior to birth, the fact that his or her genetic makeup is of the same kind as that of human beings who have been born, and the fact that he or she will usually develop a complete set of organs that are separate from that of his or her mother prior to birth.
The right to life of persons who have been born is currently recognized under international law and under the laws of most countries in the world and is generally recognized to be a fundamental right with respect to persons who have been born, but unborn children have been deprived of this right to life under the laws of some of the countries of the world due to the legalization of abortion in these countries. An unborn child’s right to life should be legally protected under international law and under the laws of each country because unborn children are human beings and were so from the moment of conception, because the right to life is not limited to human beings who have been born, and because the right to life is a fundamental and universal right that is derived from natural moral law. Abortion should be outlawed worldwide and international rights organizations should not force countries to keep abortion legal because abortion by its very nature involves the killing of an unborn human being, because a right to abortion is in conflict with the right to life of unborn children, because the right to life of unborn children is more fundamental than a woman’s right to an abortion, and because the right to life of unborn children is a fundamental, universal right that is derived from natural moral law.
