It feels like our world has never faced so many crisis all at the same time, and trying to solve them at once seems impossible. But, in 2015, the United Nations came together to develop a list of 17 Sustainable Development Goals, a blueprint for addressing all of humanity’s problems—from poverty to climate change to peace and justice. And, amazingly, every UN nation signed it. So, how is it going?

On this episode, we talk with Chris Williams, the director of UN Habitat; and Prof. Luis Bettencourt, director of the Mansueto Institute for Urban Innovation at the University of Chicago, to get some insight on how they've been studying and working on these goals, as well as their perspective on the current state of our global crisis moving forward.
