Tuesday, September 23, 2025 – A groundbreaking agreement promises protections for the world’s oceans — can it deliver?

After two decades of work, supporters of an international agreement are celebrating ratification of a tool aimed at reversing ongoing threats to oceans around the globe. Sixty nations have signed onto the High Seas Treaty. It’s a legally-binding document that maps a direction for marine biodiversity in international waters. It addresses threats such as pollution, overfishing, and damage caused by climate change. The goals align with those of many Indigenous populations, many of whom are bearing the brunt of diminished ocean diversity. At the same time, there are concerns about the ability to enforce the agreement against nations that choose to ignore it.
