Human trafficking and slavery in global supply chains would appear to be an intractable problem. But progress toward their elimination is being made. Humanity United is among the leading organizations fighting to bring an end to trafficking and slavery around the globe. It was formed 10 years ago as part of a larger philanthropic effort by eBay founder Pierre Omidyar. On this episode, we speak with Humanity United managing director Ed Marcum, who describes the organization’s mission and current work. In particular, he discusses its recent collaboration with the Walmart Foundation, The Walt Disney Company, C&A Foundation and others to create Working Capital, a $25m venture fund that will invest in tools for creating ethical supply chains. Marcum explains how the partners plan to involve leading brands, foundations and investors in the effort to promote workers' rights and ensure transparency in supply chains.
