The Invisible Ingredient
Glyphosate is everywhere, let's talk about it
A podcast series by Farmer’s Footprint
Hosted by Blair Beattie of Farmer’s Footprint, the podcast brings together widely respected voices whose work is trusted by communities and supported by evidence. Across eleven episodes, farmers, researchers, legal minds, journalists, youth organisers, and community leaders examine how glyphosate took hold, what it touches across land and society, and how oversight, markets, and culture shape its use. We place records and research beside testimony from the field, asking careful questions and listening for clear answers.
Season themes include residues and risk, GM crops and control, farmer wellbeing, regulation and accountability, food sovereignty and Indigenous knowledge, the long arc of practice change, and youth-led reform in shared spaces. Along the way you will hear from guests such as Zach Bush MD, Helena Norberg-Hodge, and a chorus of farmers and organisers reshaping how food is grown and governed.
From science to storytelling, from activism to alternatives, this is where truth meets transformation. Episodes stream on Apple and Spotify, with full video on YouTube. References and resources are published at theinvisibleingredient.org.

In the final episode of The Invisible Ingredient, host Blair Beattie sits down with Farmer’s Footprints own Alana Mooi to step back and reflect on where the journey has led and what comes next. Together, they explore the urgent need to move beyond chemical dependency in agriculture, reframing the conversation away from simply removing toxins and toward embracing biological possibility. They discuss how working with living systems can restore soil function, strengthen ecosystems, and support human health in parallel.
This conversation urges us to consider food as more than fuel by examining its cultural, relational, and place-based dimensions, and the risks of relying solely on Western agricultural frameworks. Drawing attention to small-scale farmers and long-held practices across diverse bioregions, they highlight the value of local knowledge, biodiversity, and context-specific approaches. This closing episode affirms that there is no single solution, only many pathways shaped by land, culture, and community, and that meaningful change emerges through shared learning and collective effort.

In this episode, we sit down with Nick "Duggie" Dugmore - vigneron and founder of Stoke Wines - for a deeply human conversation that moves between vineyard rows and the inner terrain of the body. At 39, Duggie was diagnosed with stage three bowel cancer. As he traced his health journey backwards, he began questioning the invisible exposures shaping both land and body, including glyphosate and its disruption of critical biological pathways. Speaking without blame, Duggie reflects on the parallels between soil health and mental health, the pressures farmers face within chemical-dependent systems, and how illness reshaped his understanding of presence, purpose, and connection. The episode offers a grounded exploration of how the stories of land and human health are inseparably woven.

Bio:
Nick ‘Duggie’ Dugmore is the winemaker behind Stoke Wines on Kangaroo Island, recognised nationally as a Young Gun of Wine for his care for land, craft, and community. At 39, a stage 3 bowel cancer diagnosis set him on a path he never expected. When his surgeon estimated the tumour’s growth at around 16 months, Nick began tracing his exposure with precision — a process that led him to glyphosate and a series of hard truths about the chemicals embedded in modern agriculture.
Determined to understand the science and speak openly about what he uncovered, Nick has documented his journey in a series of essays and personal reflections on his website, offering both rigor and vulnerability. He also co-hosts The Power of Awareness podcast, where he supports others navigating cancer with clarity and compassion.
In this conversation, Duggie brings a rare and necessary voice — a farmer and winemaker living the consequences of exposure, willing to share what he’s learned, and calling for a future where health, farming, and honesty sit at the centre of our choices.

Bio: Sheina Crystal is the Co-Director of Re:wild Your Campus, a national, youth-led movement working to eliminate toxic herbicides and reimagine school grounds as living systems of biodiversity, beauty, and health. As a student at UC Santa Barbara, Sheina began by listening and learning—walking grounds with restoration crews, building relationships with campus staff, and asking what change might look like from the soil up.
She went on to help lead a successful campaign to ban glyphosate across all 10 University of California campuses, and co-developed the Green Grounds Certification, a program supporting ecological landscaping practices in educational institutions. Sheina now works directly with students across the country, mentoring the next generation of changemakers who are transforming lawns into habitats and campuses into catalysts for systemic change.
With insight, courage, and a deep sense of possibility, Sheina joins this conversation to speak to the power of grassroots advocacy—and the role young people are playing in shaping healthier, more life-affirming futures.

A formidable presence in the courtroom, Brent has secured billions in verdicts and settlements, including a $2 billion jury verdict against Monsanto on behalf of the Pilliod family in a case linking Roundup to cancer. He was not yet 40 at the time, making him the youngest attorney in American history to achieve a multi-billion-dollar jury win.
But Brent’s work reaches beyond the courtroom. He believes the law is a tool for truth and transformation. As one of the driving forces behind the release of the Monsanto Papers, Brent helped expose internal documents that revealed how science was manipulated and health risks were downplayed. These revelations reached regulators and institutions worldwide, sparking new scrutiny and conversations about glyphosate’s place in our food system.
With a Juris Doctor and a Master of Public Policy from Georgetown University, Brent brings both sharp legal acumen and a broader view of how justice can shape systems. He joins this series to reflect on what it takes to stand up to entrenched power, and why transparency is essential for public trust and planetary health.
