Pro-Life is a political or ethical opposition to abortion, euthanasia, capital punishment, and in some cases stem cell research and cloning. The Pro-Life position towards abortion is motivated by a belief that fetuses and embryos are human beings entitled to full legal rights.

Thousands of pro-life supporters gathered in Washington, D.C. on January 22, 2009, to protest the 36th anniversary of Roe v. Wade. The supporters marched to the The U.S. Supreme Court in the annual March for Life.

Pro-life supporters oppose Roe v. Wade, a Supreme Court decision in 1973 which legalized abortion in all states. The Supreme Court's decision in the case said laws against abortion in The United States violated a constitutional right to privacy under the Fourteenth Amendment. Roe v. Wade overturned state and federal laws that banned abortion and would challenge any laws made afterward that banned or restricted abortion.BBC: Roe v. Wade...(December 10, 2004)

Pro-life supporters gather yearly in Washington, D.C. for the March for Life. The march is held on the anniversary of Roe v. Wade. They march from the Washington Mall to the U.S. Supreme Court. The 2009 march took place on January 22, 2009, two days after President Barack Obama, who supports Roe v. Wade, took office.

Pro-Choice advocates believe that a woman should have the right to control the development or termination of her fertility and pregnancy. With this control comes a guarantee of rights to sex education, legal abortion, birth control, and fertility treatments. The Pro-Choice position also protects against forced abortion, which is one of very few issues on which they are in agreement with their Pro-Life counterparts.
