In this episode of Big Ideas Only, Mikkel Svold reconnects with Dr. Benjamin Jones, Chief Conservation Officer and co-founder of Project Seagrass, to explore what happens when seagrass theory meets real-world conservation.

Moving beyond the science of carbon capture and marine ecology, this conversation digs into the practical challenges of protecting an ecosystem that most people have never thought about. Benjamin shares stories from fishing communities in Indonesia and Florida, explains why government departments struggle to coordinate land and sea management, and describes how citizen science and political engagement have become surprisingly effective tools. The discussion reveals that saving seagrass often has little to do with planting seagrass — and everything to do with what happens on shore.

In this episode, you'll learn about:

Why 13.5 million people living below the poverty line depend directly on seagrass for their daily food
How seagrass meadows store carbon for up to 200,000 years — and release it rapidly when destroyed
The governance gap between marine and terrestrial management that makes coastal protection so difficult
Why restoring seagrass sometimes means planting fruit trees along riverbanks instead
How Wales created the world's first National Seagrass Action Plan through cross-party dialogue
What everyday actions (diet, driving, citizen science) actually connect to seagrass health
