High Seas Treaty Takes Effect as Global Ocean Protection Framework (Associated Press) 

The High Seas Treaty is the world’s first legally binding agreement to protect marine life in international waters, and its broad impacts began when it entered into force on January 17, 2026. The treaty governs the nearly half the planet’s surface comprised of vast ocean areas beyond any individual country’s exclusive economic zone—an area which faces threats from destructive fishing, shipping, plastic pollution, overfishing, and potential deep sea mining. The agreement also establishes the first framework for creating Marine Protected Areas on the high seas, which constitute about two-thirds of the world’s ocean.

Marine Life Plundered in Unregulated Fishing Zone Near Argentina (The Guardian)

One of the world’s largest unregulated squid fisheries is located in Mile 201—a largely ungoverned strip of the high seas just beyond Argentina’s exclusive economic zones. Fishing hours there have increased between 2019 and 2024 in the area, as hundreds of foreign vessels arrive annually to plunder marine life. Yet this free-for-all poses serious concerns for other marine species as well. Crews on more than 50% of Chinese vessels and a fifth of Taiwanese vessels also have revealed the unreported capture and killing of seals, with culls sometimes numbering in the hundreds.

Mexico’s Mercury Boom is Poisoning People and the Environment (Associated Press)

In Mexico’s Sierra Gorda mountains, soaring international gold prices also have created a mercury boom. Since 2011, mercury prices have skyrocketed from $20 per kilogram to between $240 and $350 per kilogram today. Most of Mexico’s mercury is trafficked to Colombia, Bolivia, and Peru for use in illegal Amazon gold mining operations that contaminate rivers and ecosystems. Yet the country’s adoption of a 2017 UN convention banning mercury mining and exports also allows artisanal mines to operate until 2032.

“There cannot be a healthy planet without a healthy ocean. It’s urgent business for us all,” said U.N. special envoy for the ocean, Peter Thomson, at last month’s UN Ocean Conference (UNOC). 

Hosted in Nice, France, the conference brought together more than 15,000 political leaders, scientists, civil society, the private sector, academic institutions, Indigenous peoples, local communities, and philanthropic organizations with the goal of identifying innovative ways to finance and mobilize action for the ocean.

Bottlenose dolphins leapt and torpedoed through the shallow turquoise waters off Florida’s Sarasota Bay. Then, a research team moved in, quickly corralling the small pod in a large net.

Norway recently announced that electric vehicles (EV) now outnumber gas-powered ones on its highways for the first time—and that these vehicles comprise 80 percent of its current new car sales. While internal combustion engines (ICE) will not disappear for several years, Norway’s sales of ICE-powered vehicles will end abruptly in 2025.

Mildred is a fish trader in Kenya. I met her a few years ago, when I was conducting research. (“Mildred” is not her real name; I promised all my participants anonymity as I worked.) She mentors, trains, and educates young women on how to dry, gut, fry fish, and run successful fish businesses.  

Human-produced pollution is the single leading cause of mortality today, yet it is not widely considered a form of violence. On July 28, 2022, the United Nations General Assembly (UNGA) voted—with 161 in favor and eight abstentions—that living in a clean, healthy, and sustainable environment is a human right. Building on a similar declaration by the United Nations Human Rights Council in October 2021, the UNGA has now reinforced the notion that the growing assaults on human health through environmental hazards are transgressions against the basic rights and freedoms of people. Efforts to create a human right to a healthy planet, and even a planetary right to health that would signifying potential rights of nature, are growing both in real activity and demand.
