Humanity United and Ashoka's Changemakers launched a global online competition to identify innovative approaches to exposing, confronting and ending modern-day slavery. Today over 27 million children and adults are in slavery or bonded labor around the world—more than any other period in human history. As one of the fastest growing criminal industries in the world, slavery remains largely hidden from the public eye and thrives on the rising global demand for inexpensive, unskilled labor and commercial sex. Deadline: June 18, 2008.
