By 2030, Africa is projected to be home to 60 percent of the world's working-age population. Columbia Journalism School's Professor Howard W. French, author of the recently published Born in Blackness, joins Doorstep co-hosts Nick Gvosdev and Tatiana Serafin to explain how this will impact global economies, climate change politics, and U.S.-China relations. French also calls for a reckoning with history that recognizes the importance of Africa in the global conversation.

Ray,  chair of the Africa Program at Foreign Policy Research Institute and former U.S. ambassador to Zimbabwe and Cambodia. For more, please go to carnegiecouncil.org.
