Since

Ancient Civilizations, the abortion debate has not seen consensus. In our

modern world, it continues to be a contentious issue that evokes strong

emotional reactions on both sides of the debate. Not only does the fundamental

question of when life begins remain disputed, but other moral and ethical

questions pervade the debate. On the pro-life side, which tends to be supported

by conservative religious groups, life at all stages is sacred and abortion is

murder. Easy access to legal abortions means that people can be irresponsible

in their sexual behaviour, safe in the knowledge that an accidental pregnancy is

easily terminated. On the other side of the debate, the pro-choice supporters

strongly emphasize that a woman has the right to decide what happens with her

own body. A woman who becomes pregnant as a result of sexual assault, or who

learns that the fetus she is carrying is compromised should be allowed the

option of abortion.
