High Seas Treaty Becomes Law to Protect Marine Biodiversity

An international agreement designed to protect marine life in the world’s oceans has officially become law. The High Seas Treaty marks a significant milestone, enabling the safeguarding of international waters that fall outside any single country’s jurisdiction. These waters cover nearly half of the Earth’s surface. After more than two decades of discussions and formal negotiations that began in 2017, the treaty is now in effect.

The treaty empowers participating countries to establish environmentally protected zones in international waters, addressing the urgent need for conservation in areas long considered the “wild west” of the ocean. Currently, less than 10 percent of the high seas are protected, despite these areas constituting two-thirds of the ocean’s expanse. According to the latest data, 83 countries have ratified the treaty, with Morocco being the 60th country to do so, triggering a 120-day countdown for it to become international law.

As the treaty takes effect, it coincides with the United States reviewing an application from a company seeking to explore the deep seabed for precious minerals. Although seabed mining is regulated under a separate treaty, the authority responsible for this has been deliberating on rules for deep-sea mining for several years without approving any commercial activities.

Rena Lee, Singapore’s ambassador who spearheaded the final negotiations, described the implementation of the treaty as “a rare opportunity to make a positive difference in the high seas and deep seabed.” This sentiment is echoed by Rebecca Hubbard, director of the High Seas Alliance, who stated, “This is a game changer. And in many ways, the work is just beginning.”

The motivation behind the treaty aligns with a broader biodiversity goal established by another United Nations agreement in 2022. This agreement aims to protect 30 percent of the Earth’s land and oceans by 2030. The successful passage of the High Seas Treaty represents a pivotal step in achieving these ambitious conservation objectives.

While countries that ratify the treaty have committed to cooperate and uphold its terms, challenges remain in enforcing these international laws. The global community will need to navigate these complexities to ensure the treaty’s effectiveness in preserving marine ecosystems for future generations.
