Snøhetta’s timber school in Kautokeino, Norway, named Čoarvemátta, is a remarkable feat of sustainable architecture, achieving 90% energy self-sufficiency despite the region’s harsh Arctic climate. Located north of the Arctic Circle, where temperatures can plummet to –45 °C, the building serves as a cultural and educational hub for the Sami community, housing the Sami National Theatre Beaivváš and the Sami High School and Reindeer Herding School. The structure’s design is deeply rooted in Sami culture, with the name ‘Čoarvemátta’ symbolizing the strength of reindeer antlers. Built primarily from wood and featuring a vast 53,000-sq-ft sloping roof, the hub incorporates traditional slate from a previous school and boasts a unique branching shape that creates dynamic outdoor spaces. Inside, the design is functional and aesthetically pleasing, with natural wood surfaces complemented by Sami art that adds vibrant touches of red and blue.

The Čoarvemátta building adheres to the Passive House Standard, a stringent green building standard that emphasizes high insulation and airtightness, making it incredibly energy-efficient. The hub’s energy needs are primarily met through an innovative geothermal system comprising 40 geo-wells drilled 250 meters into the ground, which power heat pumps for heating and cooling. On particularly cold days, an electric boiler supplements the system. The landscaping around the building remains true to Sami traditions, avoiding urban park-like spaces and preserving the natural environment. Soil removed during construction was carefully stored and replaced to protect the existing seed stocks, demonstrating the project’s commitment to sustainability and cultural sensitivity.

Researchers estimate that human activities have driven over 100,000 species to extinction, far surpassing the 777 species officially recorded by the International Union for Conservation of Nature (IUCN) since 1500. The challenge in determining the precise number of extinctions lies in the fact that the IUCN’s records began only in the 16th century, and they have assessed less than 5% of known species. As a result, many species may have gone extinct without ever being documented, especially in understudied regions like tropical forests. The difficulty is compounded by the fact that some of the most diverse groups, such as insects, are less likely to have their extinctions recorded compared to more visible animals like mammals and birds. This knowledge gap has led scientists to believe that the actual number of extinctions could be vastly underestimated.

To address this uncertainty, researchers like Robert Cowie have used innovative methods to estimate the true scale of extinctions. Cowie and his colleagues analyzed extinction rates in specific groups, such as land snails, and extrapolated these rates to other species, leading to an estimate that 100,000 species might have gone extinct in the last 500 years. Although this method has limitations, it provides a more comprehensive picture than the IUCN Red List. Cowie suggests that a more reasonable extinction rate might be around 100 extinctions per million species per year (E/MSY), a figure that highlights the devastating impact humans have had on biodiversity. While some scientists, like John Alroy, caution against trying to pinpoint an exact number due to the complexities involved, they agree that the current extinction rate is alarmingly high and is exacerbated by human activities. Regardless of the same figures, the consensus is clear: human impact has significantly accelerated the extinction of species, with potentially catastrophic consequences for the planet’s biodiversity.

Antarctica, often envisioned as a frozen wasteland, harbors more plant life than previously realized. The first-ever comprehensive mapping of the continent’s vegetation, using satellite imagery, has revealed around 45 square kilometers of photosynthetic life, primarily moss, lichen, and algae. These resilient plants thrive in the harsh Antarctic environment by harnessing sunlight for photosynthesis, playing a crucial role in carbon absorption and soil nutrient processing. This groundbreaking study, published in Nature Geoscience, underscores the significance of tracking this vegetation as it not only reflects the current state of the ecosystem but also provides essential data for future conservation efforts. The research, conducted by a team from the University of Edinburgh and various international partners, highlights the uneven distribution of plant life, with 80% concentrated on the Antarctic Peninsula and nearby islands.

When confronted with a charging bear, the instinct to flee can be dangerously misleading. Running from a bear can provoke its instinct to chase, escalating the situation into a potentially fatal encounter. Instead, experts recommend standing your ground, making yourself appear larger, and creating loud noises to ward off the animal. A recent video shared by Scenic Bear Viewing in Alaska demonstrated this technique, showing a group of photographers facing down a grizzly bear. One of the guides, Martin, even mimicked charging the bear, successfully causing it to retreat. This approach works because most charges are bluffs, meant to intimidate rather than attack.

However, it’s equally crucial to maintain a safe distance from bears in the first place. Scenic Bear Viewing advises against getting closer than 50 yards to these powerful predators, emphasizing the importance of having an experienced guide when exploring bear habitats. The bears in this Alaskan region have become accustomed to human presence over the past three decades, with no harmful interactions, as they are neither fed nor hunted by people. The tour company strives to maintain this delicate balance, ensuring that human encounters leave no trace while allowing visitors to experience these magnificent creatures safely.

The National Parks Foundation (NPF) has received an unprecedented philanthropic gift of $100 million from the Lilly Endowment, marking the largest donation in its history. This substantial contribution aims to protect and restore the most fragile ecosystems within America’s national parks, some of which are at immediate risk of degradation. While well-known parks like Glacier and Canyonlands safeguard vast tracts of pristine wilderness, other parks such as Biscayne Bay and Channel Islands are dedicated to preserving smaller, highly vulnerable ecosystems. The $100 million donation will be crucial in supporting efforts to protect these delicate environments, including restoring coral reefs, conserving wild trout species, and addressing other critical ecological needs across the national park system.

This historic donation comes when the National Park Service (NPS) grapples with a significant backlog of deferred maintenance, estimated at $24 billion. Although the Great American Outdoors Act was enacted to generate funding for national park maintenance, it only addresses a portion of the required resources. The Lilly Endowment’s gift, the first major contribution toward filling this funding gap, underscores the importance of private philanthropy in sustaining and enhancing America’s national parks. According to NPF President and CEO Will Shafroth, such gifts allow the NPS to respond swiftly to urgent conservation needs, ensuring that these treasured landscapes and ecosystems are preserved for future generations.

Eddie Wang, a Taiwanese entrepreneur, is revolutionizing sustainable fashion by turning discarded oyster shells into a unique and eco-friendly textile known as “sea wool.” Inspired by his upbringing in western Taiwan, where oysters are a significant part of the local economy, Wang saw the potential to repurpose the 160,000 metric tons of mollusk shells discarded annually. By grinding these shells, which are rich in calcium carbonate, and processing them into a flexible yarn, Wang has created a material that mimics the texture and warmth of traditional wool. This innovative approach not only helps reduce fashion waste but also offers a sustainable alternative to artificial textiles, making a positive environmental impact.

Wang’s vision has grown into a thriving business, with his factory now producing 900 tons of sea wool thread annually, generating $6 million in gross revenue. The material has gained popularity, with major retailers like Huckberry offering sea wool sweaters that compete in quality and price with those made from real wool. Beyond the fashion industry, the powdered oyster shells used to create sea wool also present an opportunity to replace limestone quarrying, a process that contributes to significant emissions and pollution. By transforming waste into a valuable resource, Wang’s sea wool not only supports sustainable fashion but also offers broader environmental benefits.
