Two point of views are opposed to each other on the abotrion dispute. The one is a point that an unborn baby is also human, so his or her right of life must be respected, and the other is the woman’s right has priority over an unborn baby’s right. This two points came out at the dispute over a 13-years-old girl’s abortion in the United States. Florida state government wanted to keep an unborn baby’s right of life by prohibiting her abortion, giving a reson “The girl is not mature enough to make such a choice.” But many people insisted strongly to keep the girl’s right to make a choice of abortion. The Florida put off her abortion accepting federal government’s petition at first, and after her mental state’s evaluation, agreed with the girl saying she was not mature enough to bear a baby and bring him or her up. There are many opinions about abortion, but most important thing of them is the right of life. All human beings have the natural right, and this, too, belong to an unborn baby, so his or her life must be kept, too. Even if abortion should be made to illegality, it’s not easy to prohibit it, because it has several of structural problems which cannot be solved only by law. To prevent abortion, above all, citizenship must be improved. Abortion is definitely not a problem only concerned with women, but the one belonging to our society. Because most reasons of the abortion are the results of society and male-oriented culture.
