Bill Cross, an expert guide, led one of the first rafting trips down a newly restored section of the Klamath River following the removal of four dams—the largest dam removal project in US history. This monumental undertaking, driven by decades of advocacy from Indigenous tribes and environmental groups, has revitalized the river and its surrounding ecosystems. The removal has opened up roughly 45 miles of previously submerged river, creating new whitewater rapids and stunning scenery. However, the restoration is ongoing, with challenges including the development of public access sites and the delicate balance between recreation and ecological preservation. The Shasta Indian Nation, whose ancestral lands were submerged for over a century, is reclaiming 2,800 acres and working to integrate their cultural heritage with the new recreational opportunities. While the river's recovery is a significant achievement, marked by the return of threatened coho salmon and other wildlife, it's also a work in progress. The tribes, along with ecological restoration companies, are actively working to further enhance the river's health and address the lasting impacts of the dams. The project serves as a model for large-scale ecological restoration and the potential for collaboration between various stakeholders.

Just 14 miles off the Southern California coast lies an underwater paradise: the Channel Islands. This area, often called California's Galapagos, boasts incredible biodiversity, thriving within 13 designated MPAs that protect roughly 21% of the surrounding waters. These areas, accessible for swimming, surfing, and diving, prohibit fishing and other potentially harmful activities. However, a required review of these MPAs is currently underway, considering proposals to expand or reduce protections. Stakeholders, including tribes, fisheries, and recreators, have submitted 20 petitions with varying suggestions. Scientists highlight the success of the MPAs, citing increased biomass, species populations, and spillover effects benefiting nearby fisheries. For example, lobster production outside protected areas increased by 225%. Ecotourism, driven by the abundance of marine life, also contributes significantly to the local economy. Despite this evidence, expanding protections faces challenges, with commercial fishers expressing concerns about potential restrictions. The review process is politically charged, with conservation efforts facing headwinds both locally and nationally. While the future of these MPAs remains uncertain, the abundance of life within the protected areas serves as a testament to the value of conservation, offering a glimpse into what could be achieved with expanded protection and continued efforts to preserve this remarkable ecosystem.

In Uganda's Mbale district, plastic bags, known locally as "buveera," are polluting farmland, impacting coffee production. This problem, long prevalent in Kampala, is now reaching remote areas. Farmers are concerned about the effects on their land. Globally, plastics are increasingly found in farm fields, exacerbated by climate change. Microplastics, often smaller than five millimeters, are altering ecosystems and entering the human food chain, raising concerns about health impacts. A UN report highlights soils as major receptors of agricultural plastics, potentially more polluted than oceans. Experts emphasize the need for major engineering solutions due to the scale of the problem. Microplastics originate from various sources, including agricultural plastics, clothing, medications, and beauty products, sometimes found in fertilizer. While agriculture accounts for only a small percentage of global plastic use, packaging contributes significantly. Studies show microplastics can be absorbed by plants and enter the food chain, raising concerns about long-term health effects. Climate change is worsening the issue by increasing reliance on plastics for crop protection and increasing the breakdown and transport of plastic particles. A recent study showed microplastics can impact plant photosynthesis. Despite a global treaty on plastic pollution being negotiated, solutions are hampered by a lack of political will and the difficulty in tracking plastic waste. Companies are attempting to improve recycling, but challenges remain. Researchers are exploring solutions like biochar filtration to remove microplastics from waterways. However, even farmers who care about soil health often lack resources to address the problem. The situation is particularly challenging for small farmers in developing countries who are most vulnerable to climate change's effects.

A new study reveals that parts of Oahu, Hawaii are sinking into the sea 40 times faster than previously predicted. This alarming rate of land subsidence, coupled with rising sea levels, poses a significant threat to Honolulu, Waikiki, and Pearl Harbor. Low-lying areas could be inundated within the coming decades, resulting in billions of dollars in infrastructure damage. Researchers from the University of Hawaii at Manoa spent nearly 20 years analyzing satellite data and found that while Oahu's average subsidence rate is around 0.6 millimeters annually, certain coastal regions are sinking at 25 millimeters per year. This accelerated sinking is particularly concerning in areas built on sediments and artificial fill, such as the industrial region of Mapunapuna. The study projects that by 2050, flood exposure in Mapunapuna could increase by over 50%, and by 2080, Waikiki, downtown Honolulu, and Daniel K. Inouye International Airport will experience more frequent flooding. The authors warn of major disruptions to Hawaii's tourism, coastal development, and ecosystems, with over $12.9 billion in infrastructure at risk on Oahu alone. The research aims to inform policy-makers and help mitigate the risks through improved flood exposure assessments, infrastructure resilience, and long-term urban planning.
