916: Seed Sovereignty in the Age of Corporate Control

A Seed Chat with Bill McDorman

Register for our monthly Seed Chat at SeedChat.org

In This Podcast: In this Seed Chat episode, Greg Peterson and Bill McDorman unpack how a handful of global corporations came to control most of the world’s commercial seed supply—and what that means for biodiversity, farmers, and local food systems. Bill traces the history from small regional seed companies to mergers, patents, and Supreme Court decisions that turned living seeds into corporate assets. They also spotlight the grassroots resistance: seed libraries, landrace and adaptation gardening, community seed sharing, and regional networks working to “liberate diversity.” Listeners walk away with both a clear understanding of the problem and very practical ways to grow, save, and share seeds as an act of food freedom.

Key Questions Answered

• How did we get from thousands of small regional seed companies to just a few corporations controlling most commercial seed?
• The episode traces a decades-long process of mergers, acquisitions, and the pursuit of patentable seed “assets” that could be put on corporate balance sheets, turning diversity built over 10,000 years into a narrow set of owned varieties.
• Why does the intersection of free-market capitalism and biology create such problems for seeds and farmers?
• Bill explains that when profit-maximizing logic is applied to living systems, everything that doesn’t immediately generate revenue—like locally adapted varieties and genetic diversity—gets discarded, even though it’s what makes agriculture resilient.
• What role did patents and legal decisions like Diamond v. Chakrabarty play in this consolidation?
• Once the Supreme Court allowed life forms “invented by humans” to be patented, seeds could be owned like machinery. That shift unlocked new financing for takeovers and accelerated consolidation, often at the expense of traditional, community-developed seed diversity.
• How are people and communities around the world pushing back and rebuilding seed sovereignty?
• The conversation highlights European and global movements like Let’s Liberate Diversity, ETC Group, and numerous nonprofits and seed networks that are preserving and sharing open-pollinated, locally adapted seeds outside of corporate control.
• What can individual gardeners and local groups actually do that makes a real difference?
• Listeners are encouraged to grow and save their own seeds, increase diversity in their gardens, participate in or start seed libraries, and plug into grassroots projects and classes that teach adaptation gardening and community-level seed work.
