Oceans cover more than 70% of Earth’s surface and support the food, climate, and biodiversity systems that billions of people depend on. This archive tracks real progress in marine conservation — from expanding protected areas and restoring coral reefs to reducing plastic pollution and rebuilding fish populations. Each story focuses on what’s working and who is making it happen.
The Clean and Healthy Oceans strategy from the U.N.’s Food and Agriculture Organization aims to curb land-based pollution of our oceans through policy and regulatory innovation, infrastructure investments, and nature-based solutions.
Indonesia will reduce its overall tuna catch by 10% over the course of three years, citing unsustainable current levels of fishing.
The current estimates suggest that as many as 2,000 blue whales travel up from Mexico to Southern California waters every year, a large chunk of a global population that may be topping 25,000.
Coral reef restoration along Hawaiʻi’s Big Island just got a serious boost: a new $25 million initiative called Ākoʻakoʻa is taking on 120 miles of degraded reef off the Kona coast. The name means both “coral” and “to assemble,” and that’s the whole idea — marine scientists, Native Hawaiian practitioners, state agencies, and local nonprofits working as one. A new propagation facility in Kailua-Kona will grow heat-resilient corals while researchers test what helps reefs bounce back. Guiding it all is the Hawaiian principle of Mālama I Ka ʻĀina, caring for the land so the ocean can thrive. With reefs in trouble worldwide, this kind of partnership — Indigenous wisdom and Western science as equals — is a model other coastal communities will want to watch.
Ecuador just pulled off the largest debt-for-nature swap ever signed, unlocking an estimated $450 million for Galápagos marine conservation over the coming decades. The deal works by trading expensive international bonds for a cheaper loan, then channeling the savings into a new independent fund overseen by a board that mixes government ministers with civil society voices. Roughly $12 million a year will flow to park rangers, fisheries monitoring, and enforcement across one of the planet’s most extraordinary marine ecosystems — home to marine iguanas and the world’s northernmost penguins. Several Caribbean and Pacific island nations are already exploring similar structures, suggesting this could become a template for protecting threatened ecosystems wherever heavy debt and rich biodiversity overlap.
The area is frequented not only by blue whales, but also by humpback whales, sei whales, at least two species of dolphin, the South American sea lion, and colonies of penguins.
Zebra shark rewilding just hit a remarkable milestone: the first captive-bred eggs have been released into the waters of Raja Ampat, Indonesia, marking the first attempt ever to restore an endangered shark species to the open ocean. Behind it is ReShark, a coalition of 44 aquariums across 15 countries working alongside local communities and government to return 500 sharks to their native reefs. Decades of overhunting had pushed zebra sharks toward local extinction, and even strong marine protections weren’t enough to bring them back on their own. If the model works here, scientists believe it could reshape how the world recovers endangered sharks and rays — proving that aquariums, communities, and conservationists can together do what none could manage alone.
Ocean protection got a major boost at the 2023 Our Ocean Conference in Panama City, where delegates made 341 pledges worth nearly $20 billion. Host country Panama led by example, expanding its Banco Volcán Marine Protected Area by more than 36,000 square miles and bringing safeguarded waters to over half its exclusive economic zone. Bloomberg Philanthropies and Arcadia launched a $51 million fund to help Indigenous communities, NGOs, and governments work toward protecting 30% of the world’s oceans by 2030. Neighboring countries also pooled $118.5 million to strengthen the Eastern Tropical Pacific Marine Corridor, a reminder that migratory species don’t recognize borders. The harder work now is turning these promises into real protection on the water.
For the first time, the world has a binding legal framework to protect life across the high seas — the vast international waters that cover roughly half of Earth’s surface and have long existed beyond the reach of environmental law. More than 190 countries agreed to the deal, which creates a pathway to establish marine protected areas in waters that are currently almost entirely unguarded. The ocean absorbs carbon, produces oxygen, and sustains biodiversity we’re only beginning to understand. This treaty shows that even the hardest global problems can bend toward cooperation.\n\n*Word count: 84*
The government intends to increase the extent of the Macquarie Island marine park. The island between Tasmania and Antarctica is a vital place for seabirds, penguins, and seals to eat and raise their young.
