In this episode, we dive deep into the mysterious and lawless world of the high seas with marine scientist, journalist, and author Olive Heffernan. From illegal fishing and deep-sea mining to climate intervention experiments and untapped biodiversity, Olive explains why these international waters — which cover nearly half the Earth’s surface — may be the most important and endangered part of our planet.

Learn about the new UN High Seas Treaty, what’s at stake if it isn’t ratified, and why protecting these waters is crucial for climate stability, ocean health, and global justice.

Olive also shares behind-the-scenes stories from her travels to the Arctic, Antarctic, and Mediterranean, what it’s like being a woman reporting from the frontlines of science, and what each of us can do to make a difference.

🎧 A must-listen if you're into climate change, ocean conservation, biodiversity, and future tech.
