Chile has designated more than one million square kilometres of its Pacific waters as fully protected ocean, adding to a string of conservation decisions that have made the country one of the world’s most ambitious marine guardians. The move shields some of the most biodiverse and ecologically significant waters in the Southern Hemisphere from industrial fishing, deep-sea mining, and other extractive activities.
At a glance
- Chile marine protection: The newly protected zone pushes Chile’s total fully protected ocean area past one million square kilometres, a threshold few nations have crossed.
- Biodiversity hotspot: The waters cover critical habitat for whale sharks, blue whales, sperm whales, sea turtles, and hundreds of endemic fish and invertebrate species found nowhere else on Earth.
- Indigenous stewardship: Indigenous coastal communities, including Rapa Nui and Kawésqar peoples, have long managed portions of these waters and played an active role in advocating for stronger protections.
Why this moment matters for ocean health
The world’s oceans are under sustained pressure. Industrial fishing fleets have depleted global fish stocks by roughly one-third since the 1970s, and warming seas are bleaching coral systems and disrupting food chains from the seafloor upward. The scientific consensus, reflected in the United Nations Environment Programme’s 30×30 framework, is that protecting at least 30 percent of the planet’s ocean by 2030 is the minimum threshold needed to halt the worst biodiversity losses.
Chile’s expansion moves the global community meaningfully closer to that goal. With this designation, Chile now protects a stretch of ocean larger than Egypt — a marine estate that includes the waters around Easter Island (Rapa Nui), the Desventuradas Islands, and the Juan Fernández Archipelago.
Full protection means no industrial take. Commercial fishing vessels, seabed mining operations, and oil and gas exploration are excluded. Scientific research and small-scale fishing by local communities can continue under regulated conditions, a structure conservation researchers say produces better long-term outcomes than blanket exclusions that ignore resident populations.
A decade of building toward this milestone
Chile didn’t arrive here overnight. The country created the Nazca-Desventuradas Marine Park in 2016 C.E. and the Easter Island Marine Protected Area in 2018 C.E., moves that drew international attention and helped shift the political conversation about what ocean conservation at scale could look like in Latin America.
Those earlier designations were driven partly by pressure from National Geographic’s Pristine Seas project and local Indigenous advocates who documented the ecological richness of the waters and argued that full protection was the only option commensurate with what was at stake. Scientific surveys found fish populations inside the protected areas recovering faster than models had predicted — evidence that buoyed the case for expansion.
The current announcement extends that protected network significantly, connecting previously isolated patches into a more coherent system. Marine ecologists note that connectivity between protected zones is crucial: fish and marine mammals don’t observe boundaries, and a fragmented patchwork of reserves is far less effective than a linked corridor.
The Rapa Nui dimension
The waters around Easter Island — Rapa Nui — carry particular weight in this story. The Rapa Nui people proposed a fully protected marine area around their island years before the Chilean government acted, arguing that their ancestral relationship with the ocean and the island’s extreme isolation made it uniquely vulnerable to outside exploitation.
Their advocacy was a direct catalyst for earlier Chilean designations, and their continued engagement shaped the terms of the current expansion. Recognizing Indigenous communities as genuine partners in marine governance — not just stakeholders to be consulted — has become a defining feature of how Chile frames these protections. Whether that partnership translates into durable co-management authority, with real decision-making power rather than symbolic inclusion, remains an open question that conservationists are watching closely.
What comes next
Designation is the beginning, not the end. Research from the International Union for Conservation of Nature consistently finds that “paper parks” — areas legally protected but poorly enforced — provide little real benefit. Chile’s ability to monitor more than a million square kilometres of remote Pacific ocean with limited coast guard capacity is a genuine challenge. Satellite tracking, drone surveillance, and partnerships with international monitoring organizations like Global Fishing Watch are helping, but coverage gaps remain.
Funding is the other constraint. Long-term protection requires not just legal designation but sustained investment in enforcement, scientific monitoring, and the community programs that give local people an economic stake in conservation rather than extraction.
None of that diminishes what this moment represents. More than a million square kilometres of ocean — teeming with life that evolved over millions of years in relative isolation — now has legal protection that didn’t exist before. For the whales, the sharks, the endemic fish, and the communities whose cultures are woven into these waters, that is not a small thing.

COP30 pledges recognition of 160 million hectares of Indigenous land rights
At the COP30 World Leaders Summit in Belém, Brazil in November 2025, 15 governments pledged to formally recognize Indigenous land rights over 160 million hectares by 2030 — an area the size of Iran — through the Intergovernmental Land Tenure Commitment. Brazil committed at least 59 million hectares. More than 35 donors renewed a $1.8 billion Forest and Land Tenure Pledge. The Tropical Forest Forever Facility secured nearly $7 billion, with 20% directed to Indigenous peoples. It was the largest Indigenous participation in COP history.

Ghana declares its first marine protected area to rescue depleted fish stocks
Ghana has declared its first marine protected area near Cape Three Points, targeting fish stocks decimated by decades of overfishing. The Ghana marine protected area marks a historic shift for a nation where millions depend on the sea for food and income — and could signal broader change across the Gulf of Guinea.

U.S. researchers cut Alzheimer’s risk by half in first-ever prevention trial
An Alzheimer’s prevention trial at Washington University School of Medicine has produced the first clinical evidence that clearing amyloid plaques from the brain before symptoms appear can cut the risk of developing the disease by roughly half. The results, published in The Lancet Neurology, tested the antibody drug gantenerumab in people with rare genetic mutations that make Alzheimer’s nearly inevitable — and found that early intervention can change the disease’s course.
