Promoting gender equality is crucial to combating global poverty, a point Nicholas Kristof and Sheryl WuDunn make in their new book, Half the Sky: Turning Oppression into Opportunity for Women Worldwide [6]. Millions of women and girls in developing countries die, are killed, or suffer brutality-because they are female. The authors, who share a marriage and a Pulitzer for their reporting for The New York Times, relate stories of horrific abuse-sex trafficking, honor killings, mass rape, maternal mortality-but also of terrific courage and resilience. Sojourners associate editor Molly Marsh spoke with them about their work.
