Nature limits all systems — nothing grows forever. Economic systems built around growth, like ours, are no different. Ellen revisits that topic with bio-mimicist Jamie Brown-Hansen about what scientific inquiry into natural systems teaches regarding sustainable economic systems that last for eras rather than just decades. The theme is picked up by Bernie Sanders as he reflects on the precarious nature of our national economy while Matt Stannard considers what’s not being addressed on the topic by the presidential candidates. And co-host Walt McRee talks with New Hampshire State Representative Valerie Fraser about the movement underway there to create a public State bank.
