In the hot seat this week - Nick Valenzia, Co-Founder of Leafr. We sat down with Nick to understand the "Green Skills Gap" and what that means in an economy where getting a job in sustainability feels so difficult. How is AI influencing the green jobs market? How is the lack of specialized sustainability professionals holding back global climate goals? What do professionals need to be aware of in order to succeed? What is this gap?

Nethra and Cecilia also explore how Leafr is building the world's largest network of independent sustainability specialists and curating the only rated database of sustainability tools and resources. Nick shares insights on what companies really need to make progress, how Leafr is changing the game for overburdened sustainability teams, and why accessibility and quality assurance are key to scaling impact.

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.

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.
