After 13 years working on major accounts like Nike and Corona at one of the world's most influential creative agencies, Purdy did something unusual: he wrote his own job description and asked to become the agen...

Mitch Ratcliffe sits down with Wong to discuss Terraformation, t...

Ten years after the Paris Agreement, the world's climate negotiators will gather in Belém, Brazil this November for COP 30, a summit many are calling a critical juncture for global climate action. After COP 29 in Baku ended with what developing nations called a woefully inadequate $300 billion annual commitment—far short of the $1.3 trillion economists say is needed—can multilateral climate negotiations still deliver the justice an...

Every solar array, battery system, and EV charger installed over the past decade will eventually need to be decommissioned. Yet there's no unifying system to handle that flow of materials—no operating system for the reverse supply chain that the circular economy depends on. While Americans recycle 97% of vehicles, we recycle less than 20% of electronics, leaving valuable critical minerals like lithium, cobalt, and gold to languish ...

Turn on any faucet in America, and chances are the water meets federal safety standards. Yet Americans buy 50 billion single-use plastic water bottles annually—enough to circle the Earth 200 times if laid end to end. The bottles take 450 years to decompose, and recent research found that a single liter of bottled water can shed up to 240,000 pieces of microplastic ...

For decades, our relationship with waste has been defined by disposability and denial. The disposability of everything from coffee cups and cigarette butts to smartphones, and the denial about where it all goes when we're done with it, means that humans generate over 2 billion tons of waste globally each year, with Americans alone throwing away 290 million tons of ...

    Every summer, the same devastating story repeats across America: lakes that families have cherished for generations suddenly turn toxic green. Half a million people in Toledo lose their drinking water when Lake Erie blooms with poison algae. Or, Florida's red tide costs the state billions in lost tourism. But some of the most damaged bodies of water in America are getting a cleanup. Meet Dr. Mark Heilman, Vice President of Environm...

    Solar and wind have become the cheapest sources of power in human history, but political headwinds threaten to derail the fastest energy transformation ever recorded. At this crucial juncture, how do we ensure America doesn't surrender its technological leadership in clean energy to nations more willing to embrace the future? Meet Bill McKibben, legendary environmentalist and author whose four decades of climate writing have shaped...

    The carbon removal industry stands at a crucial crossroads. While cutting emissions remains essential, avoiding catastrophic warming now requires pulling billions of tons of CO2 from the atmosphere permanently. But as this nascent field grapples with questions of legitimacy, scalability, and accountability, a critical challenge remains: How do we build the infrastructure needed to track, verify, and certify that carbon has actually...

Tune in to meet Kelsey Timmerman, author of the new book, Regenerating Earth, from Patagonia Books, who faces a heartb...

    The scale of our plastic waste crisis is staggering: the U.S. alone uses over 100 million plastic utensils every day, most of which are used once and tossed into landfills where they'll persist for centuries. From ocean pollution to overflowing campus dumpsters after lunch rush, single-use packaging defines modern food service—but universities and businesses are under mounting pressure to embrace sustainable alternatives. Tune in t...

    The scale of our climate challenge is staggering: humans have pumped 1.6 trillion tonnes of carbon dioxide into the air and oceans since 1750, and we're adding another 40 billion tonnes every year. Even with dramatic emissions reductions, we're still on track to blow past 1.5 degrees of warming, the Paris Accord target first breached in 2024. Tune in to a conversation with Dr. Julio Friedmann, Chief Scientist at Carbon Direct. This...

      Medal of Honor: Stories of Courage

      Rewarded for bravery that goes above and beyond the call of duty, the Medal of Honor is the United States’ top military decoration. The stories we tell are about the heroes who have distinguished themselves by acts of heroism and courage that have saved lives. From Judith Resnik, the second woman in space, to Daniel Daly, one of only 19 people to have received the Medal of Honor twice, these are stories about those who have done the improbable and unexpected, who have sacrificed something in the name of something much bigger than themselves. Every Wednesday on Medal of Honor, uncover what their experiences tell us about the nature of sacrifice, why people put their lives in danger for others, and what happens after you’ve become a hero. Special thanks to series creator Dan McGinn, to the Congressional Medal of Honor Society and Adam Plumpton. Medal of Honor begins on May 28.
