Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards < Back Who do you side with? 🤔 Who do you side with?👀 In Laguna Beach, a surfer named Greg Viviani, also known as SoLagLocal, was fined for digging a hole to create a standing wave at Aliso Beach. This beach is popular for skimboarding and occasionally heavy shorebreaks. The controversy centers around the creek along the sand, which can create a standing wave when it breaks, either naturally or through human intervention. The city of Laguna Beach has been issuing citations to surfers and skimboarders who dig out the creek, arguing that it pollutes the ocean. In response, Viviani and local activists have started a petition against these regulations, claiming that the creek will naturally break and flow, and that preventing this could lead to stagnant water and bacteria buildup. It’s a developing story with ongoing debates between the local government and the surfing community.

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards < Back Hong Kong’s Dual Water System: How Seawater Is Used for Toilet Flushing Hong Kong’s Dual Water System: How Seawater Is Used for Toilet Flushing The 2024 wildfire in Los Angeles made many wonder: why can’t we use seawater to extinguish such fires? There are several reasons. Seawater is corrosive to firefighting equipment, can damage vegetation and soil, and is not always accessible inland. These challenges indicate a growing concern: how can we preserve freshwater for emergencies like wildfires? While wondering about alternative solutions, we discovered an intriguing approach in Hong Kong, where over 80 percent of the population is already served by a dual water system. But how does it work? A City of Innovation and Constraints In a city where space is limited and land prices are among the highest in the world, Hong Kong has had to innovate not only in housing but also in water management. One of its most remarkable achievements is a dual water supply system that separates freshwater from seawater, the latter used specifically for toilet flushing. Though rare globally, this system could be a creative and practical conservation strategy. How It Works: A Two-System Approach Hong Kong is one of the few places in the world with a dual plumbing infrastructure in most buildings: * Freshwater system: Supplies kitchens, bathrooms (for bathing and handwashing), and laundry * Saltwater system: Supplies seawater solely for toilet flushing By separating these functions, the city reduces its demand for potable water, a limited and costly resource, by 20 to 30 percent. Why Use Seawater? Hong Kong lacks major rivers or lakes and relies heavily on imported freshwater from mainland China, particularly the Dongjiang (East River). To reduce this dependency and improve water security, the city began using seawater for flushing toilets as early as the 1950s, expanding it significantly by the 1970s. Given Hong Kong’s coastal location, seawater is both plentiful and accessible, making the solution cost-effective and practical. Infrastructure and Maintenance To implement this system, Hong Kong built an extensive network of dedicated seawater pipelines and pumping stations. Each building typically has two water tanks and two separate plumbing systems: one for potable water and the other for flushing. Seawater undergoes basic treatment before distribution to prevent pipe corrosion and eliminate harmful bacteria or marine organisms. Although it doesn’t need to be drinkable, it must meet sanitation and safety standards. The system is managed and maintained by the Water Supplies Department (WSD). Environmental and Economic Benefits * Water conservation: Saves approximately 270 million cubic meters of freshwater each year * Cost savings: Flushing water is free or low-cost, encouraging its use * Relief on freshwater supplies: Reduces pressure on local reservoirs and imported sources Challenges and Limitations Despite its success, the dual water system presents challenges: * High construction costs: Doubling the plumbing infrastructure increases installation expenses * Retrofitting older buildings: Difficult and costly to implement in existing structures * Maintenance complexity: Operating two separate systems requires additional oversight, materials, and labor Could It Be a Global Model? While Hong Kong’s approach is unique and largely successful, it may not be easily replicated everywhere. Coastal access, existing infrastructure, and climate conditions are major limiting factors. There are also challenges such as potential impacts on marine ecosystems and the high cost of infrastructure development. Still, in the face of growing climate stress and water scarcity, Hong Kong’s system presents an innovative example worth exploring, especially if we can develop solutions that support both people and the environment.

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards < Back Federal Court OKs Radioactive Water Release into Hudson River, Source of Drinking Water for 100,000 ☢️ Federal Court OKs Radioactive Water Release into Hudson River, Source of Drinking Water for 100,000 A recent federal court ruling has approved Holtec International, the company decommissioning the Indian Point Energy Center in Buchanan, New York, to release about 45,000 gallons of treated water containing tritium into the Hudson River. 😱 What the Court Decided In September 2025, U.S. District Judge struck down New York State’s “Save the Hudson” law, which had banned the discharge of radioactive wastewater during decommissioning. The judge ruled that federal law preempts state regulation in matters involving radiological safety, giving primary authority to the U.S. Nuclear Regulatory Commission (NRC). 💦 What’s in the Water According to Holtec and NRC filings, the treated water contains tritium, a radioactive form of hydrogen that forms part of water molecules and cannot be removed with conventional treatment methods (NRC Backgrounder on Tritium). Other radionuclides and heavy metals are reported to be below detectable or regulatory limits, though not necessarily zero. 👦 How Many People Depend on the Hudson The Hudson River Drinking Water Intermunicipal Council (Hudson 7) reports that about 100,000 people in the Hudson Valley rely on the river for drinking and bathing after treatment (Hudson 7, 2024 Fact Sheet). Drinking-water treatment removes most contaminants, but tritium passes through conventional filtration, meaning safety relies on dilution and monitoring rather than removal. 🧪 Safety and Scientific Context Tritium is reportedly considered low-risk when properly regulated and diluted, emitting low-energy beta radiation that cannot penetrate skin and does not bioaccumulate, unlike substances such as mercury or cesium. Studies say, most tritium is eliminated from the human body within about 10 days. Even for people who drink tritiated water daily, the total radiation dose over time remains far below levels that could cause sickness or serious health effects, if the discharge contains only tritium and stays within federal safety limits, according to the U.S. NRC. However, independent scientists and environmental groups have raised questions about transparency and verification, noting that even trace amounts can enter river sediments or aquatic ecosystems over time. Public oversight and independent testing are essential to ensure long-term environmental safety. ‼️ Controversy The discharge plan remains controversial because what is considered “safe” depends on assumptions about dilution, monitoring, and cumulative exposure. Environmental organizations, including Riverkeeper and Scenic Hudson, continue to advocate for independent testing before any release. This debate is not just about the Hudson River; it highlights key challenges of clean energy, even when the power produced is low-carbon.

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards < Back Panama grants legal rights to sea turtles 🤓 Panama grants legal rights to sea turtles🐢 Panama's new law grants sea turtles the right to a pollution-free environment and recognizes their rights as living creatures. According to Erica Lyman, a clinical law professor and director of the Global Law Alliance for Animals, most wildlife protection laws are enacted based on perceived human benefits. However, Panama's law takes a different approach by prioritizing the needs of sea turtles and emphasizing the responsibility of humans to modify their behavior to accommodate those needs. These rights acknowledge their legal entitlement to exist and thrive, and the law permits lawsuits in case of any violations to these rights. The law enforces strict consequences for those disrupting sea turtle habitats, including canceling operating permits for irresponsible developers and tourism operators. It also prohibits all domestic and international commerce in sea turtles, parts, and eggs, except for subsistence use by select traditional communities.

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards < Back How climate change is impacting the livelihood of the semi-normadic Marsh Arabs 🐊 How climate change is impacting the livelihood of the semi-normadic Marsh Arabs 🌿 The Ahwaris, also known as the semi-nomadic Marsh Arabs, have inhabited the marshlands at the convergence of the Tigris and Euphrates rivers for thousands of years. Although their exact population is not precisely documented, estimates suggest there are around 50,000 Ahwaris in Iraq and approximately 20,000 in Iran ( UNDP , 2023). Their history spans at least 5,000 years, making them one of the oldest surviving indigenous groups in the region ( UNESCO , 2016). A Unique Culture Rooted in the Marshes The Ahwaris’ way of life remains closely tied to the marshes. They construct their homes on floating islands known as tuhul , using reeds and Qasab grass sourced locally. These reed-based dwellings, built without nails, wood, or glass, have been crafted using the same sustainable methods for centuries, minimizing their ecological footprint. Their portability allows them to adapt to fluctuating water levels ( Eden in Iraq , 2022). Challenges: Climate Change, Conflict, and Migration The Ahwaris have faced significant hardships due to conflict, economic struggles, and limited access to essential services. Climate change has further exacerbated their difficulties, with droughts and dam projects reducing the marshes to nearly one-third of their size from a century ago ( UNESCO , 2016). As water sources dry up, many Ahwaris are forced to migrate to urban areas, leaving behind their traditional occupations and disrupting social cohesion. Hope Through Eco-Tourism Eco-tourism has emerged as a potential solution to preserve the Ahwari way of life while creating economic opportunities, particularly for women and youth. By fostering sustainable development, tourism initiatives can help reduce migration, enhance community stability, and safeguard the region’s cultural heritage ( UNDP , 2023). A Cultural Legacy: Abuḏiya Poetry and Song Despite modern challenges, Ahwaris continue to preserve their rich cultural traditions, including abuḏiya —a poetic and musical form expressing grief, longing, and resilience. Often compared to the Blues, abuḏiya remains a testament to the endurance of the Ahwari people. A notable example is the performance of Masoud El Amaratly, an Iraqi singing legend ( YouTube , 2023).

Experts suspect that severe drought and high temperatures caused by low river levels have made the water too hot for the dolphins, resulting in their deaths. Biologists and experts are conducting autopsies to determine the exact cause of death and are considering factors like bacterial infections. At least 70 of the carcasses appeared when Lake Tefé's water temperature reached an exceptionally high 39°C, more than 10 degrees above the average for this time of year. Environmental activists attribute these unusual conditions to climate change, which increases the likelihood and severity of droughts and heatwaves, though the role of global warming in the Amazon's current drought is still uncertain. This event threatens the already vulnerable pink dolphins, a unique freshwater species found in South American rivers.

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards LAND < Back Painting Cows Like Zebras: The Ig Nobel Prize-Winning Study 🐂 Painting Cows Like Zebras: The Ig Nobel Prize-Winning Study 🦓 Before you scroll, take a guess why is this cow painted like a zebra? Alright, here’s the answer. In a creative approach to pest control, a group of Japanese researchers found that painting cows with zebra-like stripes can significantly reduce the number of biting flies that land on them. This unusual yet effective idea earned the team the 2025 Ig Nobel Prize in Biology, an award that celebrates research that is both amusing and thought-provoking. The Study Led by Tomoki Kojima of the Aichi Agricultural Research Center, the researchers set out to test whether zebra-style stripes could protect livestock from biting insects without using chemical repellents. The experiment involved Japanese Black (Wagyu) cows, which have naturally dark coats. The cows were divided into three groups: a) White-striped cows, painted with zebra-like patterns. b) Black-striped cows, painted with black lines that blended into their coats. c) Unpainted cows, which served as the control group. The team observed the cows in a pasture, counting how many flies landed on each and recording behaviors such as tail flicking, head shaking, and skin twitching, which indicate irritation from insect bites. (please refer to the image below) The Results The results were striking. Cows painted with white zebra-like stripes attracted about half as many biting flies as unpainted or black-striped cows. They also showed fewer defensive movements, suggesting they were less bothered by insects. The researchers concluded that the pattern of contrasting stripes, rather than the paint itself, was responsible for the effect. One possible explanation is that the stripes confuse the flies’ visual system or disrupt the way they perceive polarized light, making it harder for them to land accurately. Why It Matters Biting flies do more than annoy livestock. They cause stress, reduce feeding and milk production, and can transmit diseases. Traditional insect repellents and pesticides are costly and can have environmental or health impacts. Painting cows with water-based paint offers a low-cost and chemical-free alternative that could help farmers reduce insect harassment. The findings also support a long-standing idea in evolutionary biology: zebra stripes may have evolved to repel biting flies. By copying this natural design, scientists have created a simple and practical solution inspired by nature. The Ig Nobel Prize celebrates discoveries that make people laugh and then make them think. What started as a playful idea has turned into a promising step toward sustainable pest control in agriculture.

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards LAND < Back Insect Collapse: Alarming 72.4% Population Decline in Remote Wilderness in Colorado, 20 year study says Insect Collapse: Alarming 72.4% Population Decline in Remote Wilderness in Colorado, 20 year study says A 20-year study in Colorado has revealed a dramatic decline in flying insect populations even in areas far from human activity. Researchers monitoring insects in remote wilderness sites found that the number of flying insects has dropped by more than 70 percent since the study began, highlighting a serious ecological concern. Insects of the study subjects: Diptera (flies) – many small flies, gnats, midges Hymenoptera (wasps, bees, some small flying ants) – mostly pollinators Lepidoptera (butterflies and moths) – mainly smaller species present in the meadows Coleoptera (beetles) – only the flying beetles were counted, not ground-dwelling species The decline occurred in locations largely untouched by urban development, agriculture, or pesticide use, which are commonly associated with insect losses. Because these human pressures were minimal, the researchers concluded that rising summer temperatures were the most likely driver. Warmer summers, consistent with climate change trends, can disrupt insect development, reproduction, and survival. While climate change is strongly implicated, the researchers do note that ecosystems are complex. Other factors such as long-range pollution or invasive species could play minor roles, but the magnitude of the decline in these protected areas strongly points to temperature increases as a key factor. Insects play a crucial role in ecosystems. They pollinate plants, recycle nutrients, and serve as food for birds, mammals, and amphibians. A loss of more than 72.4 percent could have cascading effects throughout food webs and ecosystem stability. This study demonstrates that climate change can impact even the most protected wilderness areas. Preserving natural habitats alone is not enough to prevent ecological collapse. Global efforts to mitigate climate change are essential to protect insects and the broader ecosystems that depend on them. Sources: Sockman, K. W., & colleagues. (2025).

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards LAND < Back Chronic Wasting Disease in Deer found in 36 states Image by Montana Fish, Wildlife & Parks Chronic Wasting Disease in Deer found in 36 states in 2025 Chronic Wasting Disease (CWD) is a prion-related disease that impacts deer, elk, reindeer, sika deer, and moose. Instances of CWD have been identified in Canada, the United States, Norway, and South Korea. CWD proteins, or prions, are believed to spread among deer and elk through body fluids like feces, saliva, blood, or urine. Once introduced into an area, CWD can quickly infect deer and elk populations and persist in the environment, posing a risk to other animals even after the infected animal has died. Experimental studies have shown that CWD can infect certain animals, including squirrel monkeys and laboratory mice with human genes. But there has been no report of human infection. What are the indications of CWD? Deer affected by CWD may appear healthy for 16 months or more before displaying signs of the disease. Throughout this period, they can transmit CWD to other animals and the environment. Signs of a CWD infection include: * Listlessness or a diminished interest in their surroundings. * Lack of coordination. * Frequent lowering of the head. * Blank stare. * Walking in predetermined patterns. * Drooling and grinding of teeth. * Increased water consumption and frequent urination. * Reduced body weight. So how can the infected prions be eradicated? Unfortunately, infected prions exhibit exceptional resilience to high temperatures, with the incineration of prion-contaminated material being widely recognized as the most effective disposal method. While incineration at 1,000°C proves successful in eliminating prion infectivity, residual infectivity can persist even after treatment at 600°C!! Even when subjected to freezing for extended periods, prions maintain their capacity to induce CWD. However, a recent study by scientists at the National Institutes of Health highlights a promising decontamination method. It reveals that stainless steel wires coated with chronic wasting disease (CWD) prions can be effectively cleansed by soaking them in a 40% household bleach solution for just 5 minutes. While these approaches may prove effective for cleaning small contaminated areas or disposal of dead animals, it is evident that it would be impractical for addressing contamination in the wild.

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards LAND < Back The alleged impact of lead poisoning on Vincent van Gogh's health Vincent van Gogh and Lead Poisoning: A Possible Factor? Vincent van Gogh, one of the most renowned artists in history, suffered from severe chronic mental illness with periods of instability, erratic behavior, and self-harm. His deteriorating health led to his tragic suicide at the age of 37 in 1890. Some historians and researchers have suggested that lead poisoning may have contributed to his mental and physical symptoms , though this remains speculative. First, what is Lead? Lead is a naturally occurring element found in the Earth's crust. It can be present in soil, water, and air. Chemically, lead is represented by the symbol Pb and has an atomic number of 82 . It is a heavy metal that has been used by humans for thousands of years due to its malleability, corrosion resistance, and low melting point. Ancient Romans utilized lead extensively , particularly in aqueducts and plumbing systems, where lead pipes transported water, and lead-lined tanks stored liquids. The Latin word for lead, Plumbum , is the origin of the term "plumbing." Lead was also historically used in cosmetics , such as face powders and whitening agents. However, while some awareness of lead toxicity existed in ancient times, its full health risks were not widely recognized until the 19th and 20th centuries , particularly with industrialization and mass production. What is Lead Poisoning? Lead poisoning is a serious condition that occurs when lead accumulates in the body, causing damage to the brain, kidneys, and other vital organs. The effects of lead exposure depend on various factors, including age, overall health, duration of exposure, and lead concentration. Children under the age of 6 and pregnant women are particularly vulnerable to lead poisoning because their developing nervous systems are more susceptible to damage. The concentration of lead in the bloodstream is measured as the blood lead level (BLL) in micrograms per deciliter of blood (µg/dL). The CDC currently sets the blood lead reference value (BLRV) at 3.5 µg/dL to identify children with higher-than-normal exposure. However, recent research has shown that there is no safe level of lead exposure, and even low levels can negatively impact health. Symptoms can appear at lower levels than previously thought: Functional impairments can begin below 10 µg/dL Severe symptoms often appear at 35–50 µg/dL in children and 40–60 µg/dL in adults Extremely high levels (above 70 µg/dL) can cause seizures, coma, or death Common symptoms of lead poisoning include : Developmental delays (in children) Cognitive and learning difficulties Behavioral problems Headaches and dizziness Stomach pain and nausea Fatigue and weakness For more information on lead poisoning prevention , visit the CDC:🔗 Lead Poisoning Prevention Potential Sources of Van Gogh’s Lead Exposure Paint Pigments 🎨 Van Gogh frequently used chrome yellow , a pigment containing lead chromate . Handling and accidentally ingesting paint through hand-to-mouth contact or inhalation may have contributed to lead accumulation. Contaminated Alcohol and Water 🍷 Van Gogh was known for his heavy consumption of absinthe and cheap wine , which could have been tainted with lead from lead-glazed containers or improper distillation. Water sources in 19th-century Europe often contained lead due to outdated plumbing materials. Documented Symptoms in Letters and Medical Records In letters to his brother Theo , Van Gogh complained of: Persistent headaches Dizziness and fatigue Hallucinations (visual and auditory) These symptoms align with lead poisoning but could also be linked to epilepsy, bipolar disorder, or syphilis —conditions he has also been speculated to have had. Final Verdict: Was Van Gogh Poisoned by Lead? While Van Gogh's exposure to lead-based paint is well-documented, there is no definitive medical proof that lead poisoning was a major factor in his death. Without an autopsy or direct toxicology testing, the theory remains speculative. However, his case serves as a reminder of the dangers of lead exposure, especially in historical contexts where lead was widely used. If you are concerned about potential lead exposure, consult a doctor immediately.

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards LAND < Back Antarctica’s Lost World: Geologists Decode the Hidden History Beneath the Ice This is so exciting! New research by scientists from the University of Wisconsin Oshkosh and the University of Colorado Boulder has revealed significant insights into the geological evolution of the Trans-antarctic Mountains, a vast and largely hidden 3,500-kilometer-long mountain range buried beneath Antarctica’s ice sheets. By applying advanced chemical analysis techniques to rock samples linked to this range, the team uncovered a far more dynamic history of Antarctica’s bedrock than previously known. These findings highlight how ancient formations continue to shape the continent’s landscape and climate systems today. Revealing a Hidden Landscape Antarctica’s ice sheets conceal most of its geological structure, making direct study difficult. However, by analyzing the internal chemistry of igneous rocks known to originate from the Transantarctic Mountains, researchers were able to reconstruct the region’s geological history. Their findings suggest that the landscape beneath the ice is far from static. The rock samples show a complex history of mountain formation, erosion, and glacial activity, offering a new perspective on how the continent evolved over hundreds of millions of years. Why the Transantarctic Mountains Matter Stretching across Antarctica with peaks rising over 4,500 meters, the Transantarctic Mountains were first identified during early exploratory missions. Once referred to as the “great Antarctic horst,” this range plays a crucial role in the continent’s environmental system by acting as a barrier that restricts the flow of the East Antarctic Ice Sheet toward the Ross Sea.Understanding the formation and evolution of this mountain range is key to interpreting not only the ice dynamics of Antarctica but also potential links to global climate cycles. What the Rocks Reveal Because much of the range is inaccessible due to thick ice coverage, scientists relied on thermochronology, a method that analyzes the time-temperature history of rocks, to extract geologic clues. Their work revealed that: * The Transantarctic Mountains underwent several distinct mountain-building and erosion phases. * These geologic events were closely associated with major plate tectonic shifts . * The data provides evidence of a previous glacial period approximately 300 million years ago . The chemical signatures in the rocks suggest that many layers of ancient material are missing. This indicates intense and repeated reshaping of the terrain over vast geological timescales. Broader Implications for Climate Science Beyond reconstructing the continent’s deep past, the findings have significant implications for modern climate science. The evolution of Antarctica’s bedrock, particularly the Transantarctic Mountains, appears to have influenced the movement and behavior of ice sheets. It may also have played a role in Earth’s ocean-atmosphere interactions .This research supports the idea that ancient geologic processes continue to affect glacial patterns, climate dynamics, and even ecosystem evolution on a planetary scale. ***The image is a conceptual illustration and does not represent the actual landscape or the discovery. *** Sources: https://phys.org/.../2025-05-bedrock-analysis-reveals ... https://www.sciencealert.com/mountain-range-hiding ... https://news.wisc.edu/antarcticas-ancient-ice-sheets.../

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards LAND < Back Ant Queens Consume Infected Offspring to Prevent Disease Spread Ant Queens Consume Infected Offspring to Prevent Disease Spread In a remarkable display of survival strategy, queen ants of the species Lasius niger (black garden ants) have been observed engaging in filial cannibalism—consuming their own infected larvae—to protect their colonies from potential disease outbreaks. This behavior not only curbs the spread of infections but also recycles valuable nutrients, enhancing the queen's reproductive success. Behavioral Observations Researchers have documented that when a queen ant detects fungal infections, particularly from pathogens like Metarhizium , in her brood, she promptly consumes the affected larvae. This preemptive action ensures that the infection does not escalate to a contagious stage, thereby safeguarding the health of the entire colony. Notably, queens were found to cannibalize 92% of the infected larvae presented to them, while only 6% of healthy larvae were consumed. Reproductive Benefits The act of consuming infected offspring appears to confer significant reproductive advantages. Queens that practiced this form of cannibalism exhibited a 55% increase in egg production compared to those that did not. This suggests that the nutrients obtained from the infected larvae are repurposed to fuel further reproduction, thereby enhancing the queen's fitness and the colony's growth potential. Protective Mechanisms A critical aspect of this behavior is the queen's ability to consume infected larvae without succumbing to the pathogens herself. Studies indicate that queen ants produce an acidic, antimicrobial venom from a specialized gland located at the end of their abdomen. This venom is believed to neutralize the pathogens present in the larvae, allowing the queen to safely ingest the infected brood without adverse effects. Adaptive Significance This form of "hygienic cannibalism" serves a dual purpose: it mitigates the risk of disease spreading within the colony and recycles nutrients to bolster the queen's reproductive output. By eliminating potential sources of infection and repurposing their biomass, queen ants enhance both their own fitness and the overall resilience of the colony. This behavior underscores the complex and adaptive strategies evolved by social insects to maintain colony health and ensure survival.
