It's no secret that awful things are happening to women around the globe simply because they're female: child marriage and sex slavery are just a few that come to mind. Thankfully, some people are working to put an end to these atrocities. Nicholas Kristof and Sheryl WuDunn highlight this excellent work in their powerful two-part documentary Half the Sky: Turning Oppression into Opportunity for Women Worldwide.

The Half the Sky project began with a critically-acclaimed book, and now includes websites, music, and a social media campaign.  Pro-lady celebrities like America Ferrera, Olivia Wilde, Eva Mendes, Gabrielle Union, Meg Ryan, and Diane Lane were involved in the making of the documentary and creating a positive change in these women’s lives.

The first part of this can't-miss doc premieres tonight at 9 pm on PBS.  Check out the trailer below.
