The campaign involved an open letter signed by several high-profile celebrity activists; including Meryl Streep, Oprah Winfrey, Amy Poehler, Tina Fey, Elton John, Colin Farrell, Mary J. Blige and Shonda Rhimes. The letter was addressed to world leaders, asking them to put women and girls at the top of the development agenda in order to eradicate extreme poverty by 2030 as per the Sustainable Development Goals. It also asks for better data on females across the globe, to make sure the world can track the improvements being delivered to them.
