On this show - and in the work we do at World Within - we spend a lot of time asking one question: “What happens when the systems we depend on stop working for the communities they’re meant to serve?”Today we’re talking about one of the biggest of them all: banking.And our guide is Kat Taylor.Kat is the co-founder of Beneficial State Bank and a leading voice in the movement to build a more regenerative economy. In this conversation, she breaks down how banks really work, why the system looks the way it does today, and - most importantly - what each of us can do to be part of changing it.-----The How to Change the World Podcast is produced by World Within Studios with PRX.Producer and Composer: Alexandre MillerEditors: Eve Weston and Martin McGreevySession Engineer: Gabe Sweeney

Last episode, we featured Cole Mannix of Old Salt Co-op - a collective of ranchers outside Helena, Montana who are restoring landscapes, local food, and protecting a ranching way of life being squeezed by industrial agriculture.Cooper Hibbard is one of those ranchers.He speaks candidly about family legacy - the cherished values carried forward, and the harder history tied to the land. It’s a conversation about what we inherit - and what we choose to do with it. -----The How to Change the World Podcast is produced by World Within Studios with PRX.Producer and Composer: Alexandre MillerEditors: Eve Weston and Martin McGreevySession Engineer: Gabe Sweeney

“Land is kin.” It’s the mantra at the heart of what guides Cole Mannix and Old Salt Co-op. Old Salt is a meat company built by ranchers to take the power back from Big Beef. They do everything from pasture to plate, running multiple restaurants and an annual festival that draws thousands to Montana around food, art, and community. This is also a deeply personal story born out of a promise to save his own ranch. Cole serves land, legacy, and community - and represents what it means to take responsibility for a place and the people who depend on it.-----The How to Change the World Podcast is produced by World Within Studios with PRX.Producer and Composer: Alexandre MillerEditors: Eve Weston and Martin McGreevySpecial Thanks: Gabe Sweeney

It’s an idea so simple it could come from a five-year-old. At least that’s how Lufa Farms founder, Mohamed Hage, refers to their idea of turning idle rooftops into working greenhouses. But the real story - and this conversation - is about what it takes to build it, and what becomes possible once you do.In Montreal, Lufa has become a household name for its rooftop farms, local food delivery, and hunger relief work - and that’s just the beginning.Alongside Mo, we’re joined by Dave Furneaux, a seasoned investor and builder, to talk about their friendship, what makes the “soul” of a business, and why the risks of doing something transformative are worth it.-----The How to Change the World Podcast is produced by World Within Studios with PRX.Producer and Composer: Alexandre MillerEditors: Eve Weston and Martin McGreevySpecial Thanks: Gabe Sweeney

Coral reefs are disappearing fast - and they matter more to our daily lives than most of us realize. Sam Teicher, co-founder of Coral Vita, joins the pod to explain their fascinating approach to reef restoration, which he calls “taking coral to the gym.” We talk Category 5 hurricanes, why the Bahamas is leading this work, and why coral reefs matter whether you live by the ocean or nowhere near one. We’ve all heard what’s going wrong in the climate change fight - this is a conversation about what’s still possible.-----The How to Change the World Podcast is produced by World Within Studios with PRX.Producer and Composer: Alexandre MillerEditors: Kenny McMillanSpecial Thanks: Gabe SweeneySFX credits:Sunrise east and west coast waves skagen branch 07-27.wav by Kyster -- https://freesound.org/s/126007/ -- License: Attribution 4.0

He also shares what it was like working with Robin Williams on Broadway (and why Robin was exactly who you hoped he’d be).
