Survival in the open ocean is a constant battle. Unlike coastal ecosystems with reefs or kelp forests, the open ocean offers no place to hide. Marine animals face unprecedented challenges today, from rising temperatures due to global warming to food shortages that lead to increasing conflicts.

Efforts like the UN High Seas Treaty aim to create international marine protected areas to safeguard this global common. As we continue to uncover the secrets of the deep, it becomes increasingly clear that protecting the open ocean is essential for the health of our entire planet. Episode 03: Open Ocean
