Also on the programme, residents of a disappearing island speak up; a former Pentagon official describes one moment that changed how she thinks about drones; a slam poet from Sudan shares her poetry; and a Silicon Valley entrepreneur thinks manufactured diamonds might replace real ones. Plus, some new emojis right some wrongs when it comes to gender equality.
