Six decades ago, pioneering oceanographer and conservationist Sylvia Earle made a remarkable discovery while diving off Chile’s oceanic islands. She found the remains of a baby fur seal, a species endemic to the Juan Fernández archipelago that was believed to have been hunted to extinction in the 19th century. This discovery gave Earle hope that a small population might still exist, and indeed, a year later, a colony of 20 endemic fur seals was confirmed on Robinson Crusoe Island.Today, after decades of conservation efforts, the fur seal population has made an extraordinary recovery. An estimated 200,000 fur seals now inhabit the waters around the islands, returning them to their previous role as key members of the ecosystem. Earle, now 90, who returned to the island to dive in December 2025, described the archipelago as a critical 'Hope Spot' for marine protection.In a significant conservation victory, outgoing Chilean President Gabriel Boric recently signed an agreement to extend protection of 337,000 sq km of waters around Juan Fernández and the nearby Nazca-Desventuradas marine park. Once implemented, this 'no take' zone will extend to almost 1 million sq km, making it the third-largest such marine protected zone in the world. By doing so, Chile would protect more than 50% of its waters, placing it in a rare category alongside countries such as Panama and French Polynesia.The protection prohibits all fishing activities except within 12km of the coast, allowing the community of approximately 1,000 lobster fishers to continue their traditional livelihood. Chile is now out in front globally in ocean protection efforts, according to Earle, as most countries have been slower to commit to such extensive marine conservation.The initiative was driven by the Juan Fernández islanders and conservation NGOs who have advocated for decades to protect the unique ecosystem. The fishers, who witnessed the damage caused by industrial fishing of the orange roughy in the 1990s and 2000s, have practiced stewardship of their fishery. A survey showed 98% of residents supported extended protections, leading the fishers to present a proposal directly to the president.Julio Chamorro Solís, a lobster fisher and president of the local fishing organization, emphasized the importance of the unique ecosystem: 'We know the level of endemism we have and how fragile this ecosystem is. There's a biological treasure here.'However, the future of this expanded protection remains uncertain. The new Chilean government, led by President-elect José Antonio Kast, is currently reviewing environmental laws established by the previous administration. While the Chilean ministry of the environment has stated its intention is not to eliminate protections, conservationists and islanders await confirmation that the marine park extension will proceed as planned.This initiative aligns with global commitments to protect 30% of the world's oceans by 2030, a goal reinforced by the recent implementation of the high seas treaty. The expansion of Chile's marine protected areas represents a significant step toward achieving this ambitious target while safeguarding one of the planet's unique marine ecosystems.

Cambodia's limestone caves have long been a mystery, hiding secrets beneath their rugged exteriors. Recently, a team of explorers ventured into these karst formations and uncovered new species that have shed light on the country's rich biodiversity. The discovery highlights the importance of preserving these unique ecosystems, which are home to a wide range of flora and fauna. Cambodia's limestone caves are a prime example of the karst ecosystem, a type of landscape formed from soluble rocks like limestone. The new species found in these caves are a testament to the region's incredible natural heritage. As researchers continue to explore and study these ecosystems, they are gaining a deeper understanding of the complex relationships between species and their environments.

The USAID agency was a primary financial backer of Liberia's eco-guards, who help protect species from poaching and trafficking. The eco-guards, all of whom live in forest communities, patrol for signs of illegal activity and share their findings with rangers from nearby parks and forests.In late January 2025, the SCNL learned that USAID, the eco-guards' primary financial backer, was being dismantled by the Trump administration and that funding had been abruptly suspended. The SCNL programme manager, Michael E Taire, a Liberian who lives in the capital, Monrovia, spent several days travelling over rough forest roads to break the news to the eco-guards, who were shocked and distraught.Conservation organisations large and small lost tens of millions of dollars, forcing some to function with a fraction of the resources they had expected and others to shut down programmes entirely. Efforts to address the root causes of wildlife trafficking across the globe were axed, as was USAID's forest-protection programme in the Congo basin of central Africa, one of the agency's largest and most enduring endeavours.David Kaimowitz, a longtime advocate of community-led conservation in the Amazon basin and Central America, puts it bluntly: 'We’re talking about an end to a whole era of conservation.'Diane Russell, an American anthropologist who has worked for USAID in the Congo basin since the 1980s, says the agency helped draw international attention and funding to the region’s remarkably rich remaining forests, which are home to mountain gorillas and forest elephants. It also enabled conservation to continue through extraordinarily difficult conditions.'The callous glee with which [the Trump] administration choked off aid is something I will never forgive or forget,' Kevin Starr writes.'We cannot replace USAID, but we can do big things, because we, the locals, were the engine behind what USAID was doing in this region,' Dida Fayo says.
