Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards Western monarch population decline due to wildfires Monarch Butterflies The western monarch butterfly population remains at a critically low level. The latest Western Monarch Count recorded approximately 12,260 butterflies during the peak overwintering period in late 2025. This was the third-lowest count since monitoring began in 1997. The population has declined dramatically from the millions of western monarchs that were regularly recorded in the 1980s. The decline is linked to several factors, including habitat loss and degradation, pesticide exposure, climate change, and extreme weather. Wildfires are an additional threat because they can destroy breeding and overwintering habitat. The 2025 Palisades Fire, for example, damaged monarch habitat in Lower Topanga State Park, including vegetation that provides nectar for the butterflies. Restoration efforts are now underway in parts of the burn area. Monarchs depend on healthy habitats throughout their life cycle. Milkweed is essential because it is the only known host plant for monarch caterpillars, while flowering plants provide nectar for adults. Loss of these resources can make it harder for monarchs to reproduce, migrate, and survive. The U.S. Fish and Wildlife Service proposed listing the monarch butterfly as a threatened species under the Endangered Species Act in December 2024. The proposal also included protections for monarch habitat in coastal California. As of 2026, however, the monarch has not been given final federal protection. Individuals can support monarch conservation by planting native milkweed and nectar-producing plants, avoiding unnecessary pesticide use, protecting existing habitat, and participating in community science projects that help researchers monitor monarch populations. The western monarch's continued decline is a warning about the combined effects of habitat loss, climate change, pesticides, and extreme weather. Protecting the remaining habitat and restoring damaged areas will be important to preserving this remarkable migration for future generations.

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards A huge methane leak detected from space A significant methane leak in the Gloucestershire region, UK , a highly potent greenhouse gas, has been detected from space for the first time in March 2023. This leak, observed over a three-month period, originated from a gas main operated by Wales and West Utilities and had the potential to power 7,500 homes for a year. This satellite detection capability demonstrates the importance of rapidly identifying methane leaks to prevent their environmental impact. Methane has 28 TIMES the global warming potential of carbon dioxide (CO2) and is responsible for approximately 30% of the increase in global temperatures. The leak was initially discovered in March through satellite imagery analysis conducted by the University of Leeds, in collaboration with GHGSat, a company specializing in satellite technology. Wales and West Utilities became aware of the leak when a member of the public reported the smell of gas. The exact cause of the leak remains unclear, but methane leaks in gas pipelines are not uncommon, particularly in aging infrastructure. The satellite detection method has highlighted the potential for rapid methane leak identification. Currently, methane leaks are typically detected through challenging on-the-ground surveys, a difficult task given the extensive network of pipelines and sites. Jean-Francois Gauthier, senior VP for strategy at GHGSat, emphasized the unique value of satellites in this context, as they can provide frequent, cost-effective, and non-invasive monitoring of methane emissions. GHGSat operates nine high-resolution satellites in their constellation, orbiting at 500km overhead, which are capable of detecting gases with a 25m resolution. Prof Grant Allen, lecturer in atmospheric science at the University of Manchester, told the BBC: "There is still some work to do to fully validate the precise magnitude of such emissions estimated by satellites like GHGSat, but the capability is already proving super useful for identifying where big (preventable) sources may be."

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards The Bald Eagle’s Remarkable Comeback: A Conservation Success Story Bald Eagle Once close to extinction in the contiguous United States, the bald eagle has made a remarkable recovery through decades of legal protection, habitat conservation, and restrictions on harmful pesticides. By 1963, only 417 known nesting pairs remained in the lower 48 states. Population declines were driven by several factors, including shooting, habitat loss, and DDT exposure. DDE, a breakdown product of DDT, caused eggshell thinning in bald eagles and other birds of prey, reducing reproductive success. The recovery involved several important protections. The Bald and Golden Eagle Protection Act, enacted in 1940, protects bald eagles from actions including taking, killing, selling, purchasing, or possessing eagles, their nests, or their eggs without authorization. In 1972, the U.S. Environmental Protection Agency banned most uses of DDT in the United States. Habitat protection, nest-site management, improved water quality, and recovery work by federal, state, Tribal, and local partners also contributed to the species’ return. In 2007, the U.S. Fish and Wildlife Service removed the bald eagle from the federal list of threatened and endangered species after its recovery in the lower 48 states. The species remains protected under federal laws, including the Bald and Golden Eagle Protection Act and the Migratory Bird Treaty Act. The most recent U.S. Fish and Wildlife Service population estimate, based on 2018 and 2019 data, found approximately 316,700 bald eagles in the lower 48 states, including about 71,400 nesting pairs. This figure does not represent all of North America. Alaska alone has an estimated 70,000 bald eagles, so it is more accurate to describe the 316,700 figure as an estimate for the contiguous United States rather than for North America as a whole. The bald eagle’s recovery is an important conservation success story. It shows how science-based environmental policy, protection of wildlife habitat, enforcement of conservation laws, and long-term public commitment can help species recover. Continued protection remains important because bald eagles can still face threats from habitat loss, lead poisoning, collisions, disturbance near nests, and environmental contamination.

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards The Moon Festival: Celebrating Celestial Wonder and Ancestry The Moon Festival, also known as the Mid-Autumn Festival, is a time-honored cultural celebration with a history spanning over 3,000 years in China. Typically falling on the 15th day of the eighth lunar month, which corresponds to September or early October in the Gregorian calendar, the festival is marked by various customs and legends. While the precise origins of this festival are not extensively documented, it is deeply intertwined with ancient Chinese traditions and folklore. The festival's roots are believed to be connected to agricultural and celestial observations, including the harvest season and moon worship practices. The formalization of the Mid-Autumn Festival as a significant cultural event occurred during the Tang Dynasty (618-907 CE) and continued to evolve through subsequent dynasties. As an illustration, Empress Dowager Cixi had a deep appreciation for the Moon Festival. Despite her busy schedule as a ruler, she annually set aside five days to stage elaborate moon-worship rituals during the festival. These ceremonies were conducted with great pomp and grandeur within the Forbidden City in Beijing, the imperial palace of the Qing Dynasty. Additionally, as per folk tales, mooncakes have been associated with a legend of an emperor: the attempt to overthrow Mongol rule. Zhu Yuanzhang, along with his trusted adviser and military strategist Liu Bowen, devised a clever strategy before the Mid-Autumn Festival. They conceived the idea of concealing revolutionary messages and vital communications within mooncakes. Zhu later ascended to become the emperor during the Ming Dynasty. There are a few different versions of the story. sweets, consider pairing these treats with traditional Oolong teas, especially charcoal-baked Oolong varieties like Yancha, Dancong Oolong, White Orchid Oolong, Charcoal-baked Tie Guan Yin, or Osmanthus Tea. These teas complement the flavors of Moon Cakes beautifully, enhancing the experience of this ancient festival.

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards Air Conditioners vs Fans Fans vs. Air Conditioners: Energy Use and Heat Safety Fans and air conditioners cool people in different ways. Fans use far less electricity, but air conditioners are more effective during extreme heat because they lower indoor air temperature and humidity. Energy Use Electricity use varies by model, size, efficiency, speed setting, and outdoor conditions. Watts measure the rate at which an appliance uses power. For example, a 50-watt fan running for one hour uses 50 watt-hours, or 0.05 kilowatt-hours, of electricity. Central air conditioning: A central air-conditioning system commonly uses several thousand watts while operating. Around 3,500 watts is a reasonable example for some residential systems, but actual use can range widely depending on the home, system capacity, efficiency, thermostat setting, insulation, and weather. Window air conditioner: Many window units use roughly 500 to 1,500 watts while running, depending on cooling capacity and efficiency. ENERGY STAR recommends selecting a room air conditioner based on the size of the room being cooled. Oversized units can waste energy and may not remove humidity as effectively. Ceiling fan: Many ceiling fans use about 15 to 75 watts, depending on motor type, blade size, and speed. Efficient models may use less. Small box fan: A small box fan, around 10 inches or less, may use approximately 25 to 30 watts at high speed. Large box fan: A 20-inch box fan often uses about 50 to 100 watts, although some models can use more. Check the appliance label, product specifications, or a plug-in electricity monitor for the most accurate number. How They Cool Fans move air across the skin. This can improve comfort by helping sweat evaporate, but fans do not lower the actual temperature of a room or remove moisture from indoor air. Air conditioners remove heat from indoor air and transfer it outdoors. They also reduce indoor humidity as they operate, which can make indoor conditions safer and more comfortable during hot, humid weather. Heat Safety Fans can be a practical, low-energy way to improve comfort in moderately warm conditions. However, they should not be the only cooling strategy during extreme heat. The Centers for Disease Control and Prevention warns that electric fans may provide comfort, but when temperatures reach the high 90s Fahrenheit, they may not prevent heat-related illness. During dangerous heat, moving to an air-conditioned location, taking a cool shower or bath, drinking water regularly, and checking on people at higher risk can be safer options. Indoor temperatures can differ substantially from outdoor weather reports because of sun exposure, building materials, insulation, ventilation, window placement, and the amount of heat stored in the building. Heat stroke is the most serious heat-related illness and is a medical emergency. Warning signs can include confusion, fainting, altered mental status, seizures, very high body temperature, and hot skin. Call 911 immediately if someone may have heat stroke and begin cooling them while waiting for emergency help. Bottom Line Fans are inexpensive to operate and useful for air circulation and personal comfort. Air conditioners use more electricity but are more effective at lowering indoor temperature and humidity, especially during extreme heat. When heat becomes dangerous, prioritize health and safety. Use air conditioning when available, seek public cooling centers or other air-conditioned spaces if needed, stay hydrated, and do not rely on a fan alone to prevent heat-related illness.

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards The Leonid meteor: when sky fell The Leonid meteor storm in November 1833 was of such astonishing intensity that it sent shivers down the spines of many, conjuring vivid visions of an impending Armageddon!! A spectacular meteor storm known as the Leonid meteor storm lit up the sky across the United States, with an estimated 50,000 to 150,000 meteors falling every hour. According to newspaper reports, nearly everyone witnessed it, stirred either by the commotion in the streets or by the dazzling glow of fireballs illuminating their bedroom windows. The meteor storm was exceptionally intense because it resulted from the Earth passing through the densest part of the debris trail left behind by the comet Tempel-Tuttle. This particular comet has an orbit that intersects with Earth's path around the Sun. When the Earth crosses this debris trail, it leads to a concentrated and dramatic display of meteors. F.Y.I., the Leonid meteor shower is expected to produce another intense meteor storm in 2099 if you can manage to live a long life. This is because Earth will pass through the same dense region of debris that caused the 1833 storm. Anyway, how do you think this event was well-documented and recorded in 1833? Denison Olmsted, a Yale professor, was among those who witnessed this extraordinary event. He had limited data to study, so he appealed to the public through newspapers to provide information about the phenomenon. This crowdsourcing effort, one of the earliest of its kind, resulted in a flood of responses from people all over the country, which Olmsted used to draw new conclusions about meteors. Newspapers played a crucial role in spreading Olmsted's call for information and reporting on the meteor storm, demonstrating the power of mass media in scientific research.

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards The Impact of Monoculture Farming on Bees Monocultures: the practice of growing just one single crop in a specific area at one time . Research increasingly shows that agricultural landscapes dominated by monocultures can support fewer and less diverse bee communities than landscapes containing more diverse crops and natural vegetation. What Studies Show A 2019 study in southeastern Mexico directly compared monocultures, polycultures, and pastures across 18 sites. Researchers recorded 127 bee species and found that polycultures and pastures had significantly greater bee species richness than monocultures. The study concluded that lower-intensity agricultural systems and landscapes with more forest supported greater bee diversity. Research in the U.S. Midwest has produced similar findings. A longitudinal study in an agricultural region dominated by corn and soybean production found that wild-bee communities were less species-rich in landscapes with a high proportion of crop production. Woodland and grassland habitat were associated with greater bee richness, particularly among rarer and more specialized species. The researchers concluded that large-scale monocultures had a greater impact on bee communities than the presence of small honey-bee apiaries. Another study followed honey-bee colonies in a landscape dominated by corn and soybeans. The colonies experienced a short period of growth when soybean fields were flowering, followed by a much longer period of limited forage. Several measures of bee health declined during this period. When the bees had access to native prairie vegetation, those declines were reversed. A global analysis of 39 crop systems also found that bee abundance and species richness were generally higher in diversified fields and landscapes with more high-quality habitat. The researchers specifically noted that maintaining habitat around farms and improving agricultural management could help offset the effects of intensive monoculture agriculture. More Flowers Does Not Always Mean Better Habitat Monoculture can create an unusual situation. When a crop such as sunflower or soybean is flowering, it can provide an enormous amount of food at once and temporarily attract large numbers of bees. But when flowering ends, much of that food disappears. A study of sunflower monocultures in California found that mass-flowering crops increased bee abundance, but higher bee abundance was associated with greater parasite presence when there were few non-crop flowers available. The researchers concluded that monoculture alone cannot provide the resources needed to support healthy bee communities. This creates a feast-and-famine cycle : abundant food for a short period, followed by a shortage of diverse floral resources. Why Diversity Matters Bees need more than flowers. They need a continuous supply of different pollen and nectar sources, nesting sites, and places to shelter and reproduce. Large monocultures can remove wildflowers, hedgerows, grasslands, and other habitats that provide these resources. Pesticides can add another pressure. A 2025 study analyzing 681 crop fields across three continents found that both pesticide hazard and the loss of semi-natural habitat were associated with reductions in wild-bee abundance and diversity. The evidence therefore does not suggest that monoculture is the only reason bees are declining. Rather, large-scale monoculture can simplify agricultural landscapes and interact with other pressures, including pesticides, habitat loss, disease, parasites, and climate change. What Can We Do? Supporting bees is not only the responsibility of farmers. Homeowners, gardeners, communities, businesses, and local governments can all help. Plant native flowers that bloom at different times of the year. Leave some areas natural instead of heavily manicuring every space. Plant trees, shrubs, and hedges for food and shelter. Avoid unnecessary pesticide use. Protect meadows, grasslands, and other natural areas. Support farms that maintain diverse crops and natural habitat. Create pollinator gardens in yards, balconies, schools, and community spaces. The research points to a simple principle: a landscape that produces one crop for a few weeks is not necessarily a landscape that can support pollinators throughout the year. Adding diverse vegetation and protecting natural habitat can help turn agricultural landscapes from seasonal food sources into places where bees can actually live. Sources J. E.

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards Microalgae-Based Air Treatment: Learning From Nature to Inspire the Next Generation of Environmental Technology Photo by BioUrban As cities look for new ways to address air pollution and greenhouse-gas emissions, microalgae-based technologies offer an intriguing approach inspired by nature. These systems use living microalgae to process air. With light, the algae absorb carbon dioxide through photosynthesis while producing oxygen and biomass. Some systems are also designed to capture or reduce certain airborne pollutants. One example is BioUrban , developed by Biomitech. The company describes BioUrban as a microalgae-based air-purification system for urban and indoor environments and states that its systems can address pollutants including carbon dioxide, carbon monoxide, nitrogen oxides, PM2.5, and PM10. How It Works BioUrban units circulate air through a structure containing microalgae. Light supports photosynthesis, allowing the algae to use carbon dioxide while producing oxygen and biomass. The systems may also retain some pollutants from the air they process. Actual performance depends on factors such as system design, airflow, pollutant concentrations, light, weather, maintenance, and operating conditions. Potential Beyond Air Treatment The idea is interesting not only because of its potential application to air quality, but because it takes a different approach to environmental technology. Instead of relying entirely on increasingly energy-intensive mechanical or digital systems, microalgae can use a natural biological process to interact with the environment. Potential applications include: Localized air treatment: Supporting air-quality efforts in selected urban or indoor locations. Carbon utilization: Using carbon dioxide as part of the algae's biological growth process. Oxygen and biomass production: Creating biomass that may have potential applications in bio-based products and other uses. Environmental monitoring: Some systems incorporate sensors to monitor local air-quality conditions. Research and education: Demonstrating how biological processes can be integrated into engineered environmental systems. What the Evidence Shows Biomitech states that some BioUrban models can remove up to 85% of particulate matter from the air processed by the unit. That figure is important, but it needs to be interpreted carefully. The 85% claim has not been independently verified across different locations and real-world operating conditions based on publicly available evidence we identified. It should therefore be treated as a manufacturer claim, not as evidence that a BioUrban installation can reduce particulate pollution by 85% across an entire street, neighborhood, or city. This distinction does not diminish the potential of the technology. It highlights why independent testing, transparent performance data, and lifecycle assessment are important as these systems develop. Learning From Nature The larger opportunity may extend beyond any individual air-treatment system. Microalgae demonstrate how natural processes can perform useful environmental functions using sunlight, carbon dioxide, water, and nutrients. Learning from these processes could inspire a new generation of technologies that work more closely with nature rather than relying solely on additional energy, machinery, and infrastructure. This approach could influence innovation in areas such as carbon management, air and water treatment, resource recovery, biotechnology, and sustainable materials. The goal is not to replace technology with nature. It is to learn from nature and build better technology because of it. The Path Forward Microalgae-based systems still require research, testing, and real-world evaluation. Their effectiveness, scalability, maintenance requirements, resource use, and lifecycle impacts will determine where they can provide meaningful value. At the same time, emerging technologies should not be judged only by whether they can immediately replace existing solutions. They can also be valuable because they introduce new ways of thinking. As environmental challenges become more complex, the next generation of sustainable technology may come from combining engineering with biological systems that have been refining efficient processes for millions of years. Microalgae-based air treatment is one example of that possibility. Microalgae-based systems such as BioUrban offer an intriguing intersection of biology, engineering, and environmental innovation. It reminds us that the most sustainable technology of the future may not always be the one that uses more power to control nature. It may be the one that learns how nature already works.

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards Understanding PFAS and Potential Soil Contamination Per- and polyfluoroalkyl substances, known as PFAS, are a large group of manufactured chemicals used since the 1940s because of properties such as resistance to heat, water, oil, and stains. Many PFAS persist in the environment for long periods, which is why they are often called "forever chemicals." PFAS have been used in some stain-resistant and water-repellent products, food packaging, firefighting foams, and industrial applications. Research indicates that exposure to certain PFAS may be associated with health effects including changes in cholesterol, reduced immune response, reproductive and developmental effects, and increased risk of some cancers. However, health effects vary by the specific PFAS, exposure level, duration, and individual circumstances. PFAS in Soil PFAS can enter soil through sources such as firefighting foam releases, industrial activity, contaminated water, disposal practices, and the application of contaminated biosolids. If you suspect PFAS contamination, particularly after firefighting activity, an industrial release, or a known local contamination event, contact your state environmental agency, local health department, or a qualified environmental professional. PFAS testing and interpretation can be complex. There is no single nationwide soil standard that applies to every PFAS and every land use. Avoid digging, moving, or disposing of potentially contaminated soil without appropriate professional guidance because disturbing soil can spread contamination or increase exposure. Soil Remediation The appropriate cleanup method depends on the PFAS present, contamination levels, soil characteristics, groundwater conditions, land use, and applicable regulations. Current field-implemented approaches include: Sorption and stabilization: Materials such as activated carbon can be added to soil to reduce PFAS mobility and limit movement toward groundwater. This approach generally contains or immobilizes PFAS rather than destroying it. Soil washing: Soil washing uses physical separation and extraction processes to concentrate PFAS into a smaller waste stream. It is generally considered a transfer technology rather than a destruction method. Excavation and disposal: Contaminated soil can be removed and transported to an authorized facility. This can reduce contamination at the original site but does not destroy the PFAS. Thermal treatment: Thermal technologies are being studied and used in some applications to treat PFAS-contaminated materials. Their effectiveness depends on the specific technology, PFAS compounds, temperature, treatment time, emissions controls, and verification methods. Thermal treatment should be evaluated and managed by qualified professionals. No single approach is appropriate for every site. EPA and ITRC emphasize the importance of site-specific evaluation and continued research into PFAS treatment and destruction technologies. Gardening Near Potential PFAS Contamination PFAS can enter gardens through contaminated soil, irrigation water, compost or other amendments, and environmental sources. Some PFAS can be taken up by plants, although the amount varies depending on the chemical, crop, soil conditions, and water source. If PFAS contamination is suspected: Consider growing food in raised beds or containers using soil from a reliable, uncontaminated source. Avoid using potentially contaminated well water for irrigation until it has been tested. Avoid using questionable compost, biosolids, or soil amendments. Follow guidance from local environmental and public-health authorities. A layer of clean soil alone may not eliminate a contamination concern. PFAS can move through soil and water, so the appropriate response depends on site-specific conditions. The Bigger Picture PFAS contamination is difficult to address because these chemicals can persist in the environment and move between soil, water, plants, and other parts of the ecosystem. At the same time, research into detection, treatment, destruction, and safer alternatives continues to advance. EPA is supporting research into new approaches for treating PFAS in soil, water, and other environmental media. For communities concerned about PFAS, the most important steps are informed testing, professional assessment, careful soil management, protection of drinking-water sources, and adherence to applicable state and federal requirements. PFAS contamination can be complex, but understanding the potential sources and pathways can help communities make informed decisions. When contamination is suspected, professional testing and site-specific assessment should come before attempting cleanup or growing food in affected soil. Meanwhile, continued research, transparent monitoring, improved treatment technologies, and safer chemical practices can help reduce PFAS exposure and protect communities and ecosystems.
