A campaign by the global campaigning and advocacy organization One.org for International Women's Day aims to highlight the global gap in female education by asking people to help count to 130 million -- the number of girls not in school.

The campaign, by Droga5, drives people to the Girls Count website where they are asked to pick a number between one and 130 million and film or photograph themselves saying, singing or in any number of creative ways to depict that number. The videos will ultimately be combined to make what the organization hopes will be the world's longest user-generated film. This will be used to urge world leaders to take action ensure every girl gets a quality education.

Supporters joining the count include: Malala Yousafzai, Sheryl Sandberg, Angelique Kidjo, Bono and David Oyelowo, as well as Emmanuelle Chriqui, Tom Brady, Giselle Bundchen, Michael Sheen, Chelsea Handler, Tracee Ellis Ross and Charlize Theron.
