The High Seas Treaty is being called one of the biggest ocean conservation wins in decades, and in this episode, I break down why.

After nearly 20 years of negotiations, the United Nations has agreed on a global framework to protect biodiversity in the high seas, the vast areas of ocean beyond any country’s borders that make up nearly two-thirds of the ocean.

In this beginner-friendly episode, you’ll learn what the high seas actually are, why they’ve been so difficult to protect, what the High Seas Treaty does at a high level, and why this agreement offers real hope for the future of the ocean, even if you live nowhere near the coast.

What You’ll Learn in This Episode

• What the high seas are and why they matter to everyone
• Why less than 1.2% of the high seas was protected before this treaty
• Why negotiations took over 20 years
• The four core pillars of the High Seas Treaty
• What marine protected areas on the high seas make possible
• Why environmental impact assessments are such a big deal
• What marine genetic resources are and why equity matters
• The difference between signing vs. ratifying a treaty
• When the treaty became legally binding
• How you can take action in under two minutes!

The Four Pillars of the High Seas Treaty

1. Marine Protected Areas (MPAs)

For the first time, countries can establish marine protected areas in international waters, a critical step toward protecting migratory species and reaching the global 30 by 30 ocean conservation goal.

2. Environmental Impact Assessments

Activities like deep-sea mining and large-scale fishing must now be assessed before they happen, shifting ocean governance from reactive to preventative.

3. Marine Genetic Resources & Benefit Sharing

The treaty creates a framework to share benefits from deep-sea genetic resources more equitably, especially with countries that lack access to expensive ocean technology.

4. International Cooperation, Monitoring, & Governance

The treaty establishes systems for collaboration, data sharing, monitoring, and enforcement. This turns conservation commitments into coordinated action.

What Does Ratification Mean?

Signing a treaty means a country agrees in principle.
Ratification is when a country formally approves it through its own government and agrees to be legally bound.

The High Seas Treaty required 60 ratifications to enter into force, a milestone reached in September 2025, and it became legally binding on January 17, 2026.

How You Can Take Action

You can help turn this treaty from words on paper into real ocean protection.

The High Seas Alliance maintains a live global map showing which countries have ratified. It also provides an easy tool to send a letter urging your government to ratify. It takes about two minutes, and it truly matters.

Why This Gives Me Hope

Protecting the high seas means protecting:

• Climate stability
• Global biodiversity
• Food security
• A future that extends far beyond our own coastlines

For the first time, most of the ocean has a real, coordinated path toward protection.
