Farm to Table — sounds obvious, right? But how did something so seemingly simple become such a radical act? In this week's episode, Nethra and Cecilia unpack the history, philosophy, and misconceptions surrounding the farm-to-table movement — from its roots in counterculture to its current role in shaping sustainable food systems. They explore how industrial agriculture and globalized supply chains have created a deep disconnect between eaters and the land, and why “local” isn’t just a buzzword, but a call to reimagine what food can be.

This episode also features a special interview with Ariane Daguin, a trailblazer in ethical sourcing and sustainable farming. As the founder of D’Artagnan, Ariane revolutionized the U.S. food industry by introducing organic, free-range, and humanely raised meats to the mainstream market. Her influence laid critical groundwork for today’s farm-to-table movement. Now, through her latest venture AOOA Farm, she’s championing regenerative agriculture and mentoring the next generation of farmers and chefs with the same passion and purpose.

Whether you’re a foodie, a farmer, or just curious about where your dinner really comes from, this episode is a must-listen.

Sunscreen usage has risen exponentially over the last decade - and with summer finally here, Cecilia and Nethra are exploring the impacts of sunscreen on our bodies and marine life. How does sunscreen break down in our ecosystems? What is "Reef-Safe"? What are the solutions to the accumulation of sunscreens in our coral reefs and marine habitats? What is the difference between SPF 30 and 50? Definers, tune into this month's episode as we explore these topics and hear from our expert guest Katie Day, Senior Manager of Science and Policy at the The Surfrider Foundation.

Special guests include Mike Malterre from Stream2Sea - a sunscreen company that is completely changing the industry and innovated a product to nourish reef ecosystems!

Online shopping is convenient, but at what cost?! In this episode, we explore the massive plastic footprint hidden in your doorstep deliveries, from poly mailers to mixed-material packaging that often ends up in landfills. Cecilia and Nethra break down the environmental toll of e-commerce and spotlight the innovative seaweed-based alternative offered by cleantech startup SWAY. Don’t miss our interview with Alyssa Pace, SWAY’s Communications Lead, as we dive into how compostable packaging and seaweed/nature based solutions could help reshape the future of sustainable shipping.

Wetlands are the unsung heroes of climate resilience. From flood protection to water filtration, these ecosystems are biodiversity hot spots and are critical for the health of our planet. 

In this episode, learn more about what exactly a wetland is and how they are vital. Learn about the world's largest restoration project taking place in the Florida Everglades as we sit down with Dr. Steve Davis, the Chief Science Officer at The Everglades Foundation.

The Everglades Foundation has been the driving force behind the biggest environmental restoration project in the world. The project aims to “lubricate” the Everglades with much-needed fresh water to save an ecosystem unlike any other on the planet, ensure continued access to drinking water for more than 9 million Floridians, and prevent yearly outbreaks of blue-green algae that clog Florida waterways with a guacamole-like substance. 

Did you know that airplanes can run on waste cooking oil, municipal solid waste, forestry waste, and even algae in the form of Sustainable Aviation Fuels (SAFs)? Well, they can. 

Biomimicry, Sustainable Aviation Fuels (SAFs), and aircrafts inspired by GEESE? Learn about some of the innovations happening right now in the aviation industry and where it's headed in the coming decades. The industry has some ambitious goals of reaching net zero by 2050, running aircrafts on mainly SAFs, using newer lightweight materials to reduce fuel consumption, and even getting aircrafts to fly in the same v-pattern as flocks of geese to lower their carbon footprints.

Hosts, Cecilia & Nethra, took field trip to Toulouse, France and attended the Airbus Summit 2025. Learn about their insights from the summit and hear some lightning interviews from a few of the leading experts at Airbus such as:

• Julie Kitcher, Chief Sustainability Officer
• Jonathan Beck, Flight Operations R&T IPT Leader
• Sue Partridge, Head of Wing of Tomorrow Programme
• Antjie Bulmann, Direct Air Capture Expert

Welcome to the first episode of Hot Commodities: Chocolate & Sustainability, a new series from Sustainability Defined! Meet your new hosts, Cecilia and Nethra, as they dive into the environmental and social challenges within the chocolate supply chain. From cacao farming to the final product, they break down the key players, power imbalances, and pressing issues like deforestation, child labor, and climate change.

This episode explores the role of women in cacao production, the struggles of smallholder farmers against large corporations, and potential solutions such as agroforestry and ethical sourcing. Cecilia and Nethra aim to unpack the complexities of this "wicked problem" and empower listeners to make more informed choices. You'll also hear from agricultural economist and Former World Cacao President William Guyton, followed by insights from Tony's Chocolonely. Their interviews highlight the need for collaboration, fair trade certifications, and conscious consumer action to build a more sustainable and equitable chocolate industry.

Tune in to uncover the bittersweet truth behind your favorite treat!

This month we are continuing our break and sharing another episode from the Sea Change Podcast! However, stay tuned for next month as we are on track to introduce you to our new hosts. We are so excited to introduce you to them!

Find Sea Change on Apple Podcasts, Spotify, or wherever you get your podcasts to listen to the entire "All Gassed Up" series. 

About this Series: 

Right now in the US, there is a GAS BOOM. A liquified natural gas boom — or LNG. The US produces the most LNG in the world. And the epicenter of this massive expansion? It’s here on the Gulf Coast. “All Gassed Up,” a three-part special series from the award-winning podcast Sea Change, investigates the global expansion of liquified natural gas, or LNG. Led by co-hosts Carlyle Calhoun and Halle Parker, the series follows the journey of American gas around the world to find out if LNG is the miracle fuel it’s claimed to be. If it really can prevent a climate apocalypse. Or is it a carbon bomb waiting to go off? 

Episode 1: The Carbon Coast: The story starts in Louisiana — ground zero. We see how the rise of these massive export terminals has transformed one community. Is this big bet on LNG worth it?

Episode Description:  Hazard NJ: S2, E1: First a Miracle, Then a Curse

It was 1938 at a DuPont laboratory in far South Jersey when scientists stumbled upon the chemical that would become known as Teflon. The accidental discovery became a scientific miracle, laying the groundwork for an entirely new class of incredibly durable chemicals that would be used for all sorts of purposes. But that progress came with a toxic hidden cost that has only recently become fully understood. Now, the small town where it all started is on the front lines of a global pollution crisis.
