It's believed that more women are missing from the planet, because they are female, than all the men killed on battlefields in wars of the 20th century. In their new book, "Half the Sky: Turning Oppression into Opportunity for Women Worldwide," husband and wife team Nicholas Kristof and Sheryl WuDunn chronicle the global oppression of women. They join Patt for a discussion of these numbing statistics and a challenge to change them.
