The pro-life movement is a political and social movement focused chiefly around opposition to abortion, and support for the legal banning of elective abortion. Those involved in the movement generally maintain that human fetuses and embryos are persons, and therefore have a right to life. The movement may also be associated with opposition to euthanasia, the death penalty, human cloning, and research involving human embryonic stem cells. The pro-life movement is commonly supported among Christians and Muslims. On the issue of abortion, pro-life campaigners are opposed by pro-choice campaigners, who generally advocate for what they see as women's reproductive rights.
