Waste(d) on Ocean Science Radio

What happens after you flush? Most of us don't think about it—but maybe we should. In this eye-opening episode, we dive into one of the ocean's biggest but least discussed threats: wastewater pollution.Join us as we talk with Jos Hill, Program Director for The Nature Conservancy's Wastewater Pollution Program and creator of the groundbreaking podcast "waste(d)water." Jos reveals the shocking scale of this crisis: 80% of wastewater worldwide is inadequately treated, 58% of coral reefs are exposed to wastewater pollution, and wastewater accounts for a staggering 40% of coastal nutrient pollution—nearly as much as agriculture.Discover how even highly treated wastewater can devastate marine ecosystems, why coral disease outbreaks in the Florida Keys have been traced back to human gut pathogens, and how nutrient-rich wastewater is making coral reefs more vulnerable to marine heat waves and climate change.But this isn't just doom and gloom—Jos shares inspiring recovery stories from Kaneohe Bay in Hawaii and Tampa Bay in Florida, proving that when pollution is addressed, ecosystems can bounce back. Learn about innovative nature-based solutions, including treatment gardens that clean water while growing food for coastal communities.From the intersection of wastewater pollution and social justice to practical steps you can take in your own community, this conversation breaks the taboo around a topic that affects every person on the planet. As Jos reminds us: everyone goes to the toilet, so this issue is relevant to everyone.It's time to start talking about the dirty secret of ocean pollution—because we can't solve problems we won't discuss.Featured Guest: Jos Hill, Program Director, Wastewater Pollution Program, The Nature ConservancyLearn more: Check out the waste(d)water podcast and follow @wastedwaterpod wherever you listen to podcasts.
