people who are pro-choice believe that women should be allowed to have control over their own bodies when it comes to ending or continuing a pregnancy. they believe that, because the embryo or fetus is inside the woman's body and does not have developed enough organs to survive on its own until later in the pregnancy, it is not yet a person with rights. pro-choice people also make the argument that abortion needs to be legal in order to protect women, because when abortion is illegal, it does not completely stop abortions from happening, but makes it so that women try to do abortions on themselves or get them done by people who are not trained doctors, which puts those women in danger of death or injury. pro-choice people believe the way to prevent abortion is to make sure women only get pregnant when they want to. in addition to advocating the legality of abortion, pro-choice groups like planned parenthood often try to improve people's access to things used to prevent pregnancy (called "contraception"), and try to teach young people about sex to reduce the number of teen pregnancies.
