In an op-ed for National Geographic this week, Melinda Gates, the wife of tech magnate Bill Gates, says that she wants to provide contraceptive options to 120 million women around the world by 2020. The issue of birth control has been a focus for Gates since 2012 when she co-chaired the Family Planning 2020 summit, a global event that brought leaders from around the world together to discuss ways to grant women easy access to contraception. In her op-ed, Gates wrote, "In 2012, we made a promise to women around the world. Our actions over the next three years will decide whether we keep it."
