Networks surround and sustain us, in nature, in our bodies, in relationships, in the digital world. This hour, TED speakers explore how we rely on networks and how we have the power to shape them. Guests include ecologist Suzanne Simard, UPS executive Wanis Kabbaj, computer scientist Avi Rubin and anthropologist Robin Dunbar. (Original broadcast date: January 13, 2017)
