TSPO, a major marker of brain inflammation, may offer a way to detect Alzheimer’s disease long before memory problems and other symptoms develop. Findings published in Acta Neuropathologica suggest it could transform both diagnosis and treatment strategies. “This is the first study to really examine how early this biomarker increases and where it begins rising in the brain,” said Tomás R. Guilarte, lead researcher and dean of FIU’s Robert Stempel College of Public Health & Social Work. “If we can use this information to help delay Alzheimer’s progression by even five years, it can drastically improve patients’ lives and reduce disease prevalence.” Longstanding research on TSPO Guilarte, a recognized authority on TSPO (translocator protein 18 kDa), has investigated the protein for more than 30 years. His research helped establish it as a dependable imaging marker for identifying neuroinflammation across multiple neurological, neurodegenerative, and psychiatric conditions.

They then validated these results using donated brain tissue from members of the world’s largest community with early-onset familial Alzheimer’s, based in Antioquia, Colombia. These families carry the “paisa” mutation, first identified by the late Dr. Francisco Lopera, a co-author of the study who spent his career searching for ways to prevent Alzheimer’s. Individuals with this genetic variant often develop symptoms in their 30s or 40s and typically die in their 50s. L: The original cell image.

Microglia, the brain’s main immune cells, specifically those clustered around amyloid plaques, had the highest levels of TSPO. Notably, female mice had higher TSPO levels, mirroring real-world statistics: two-thirds of Alzheimer’s patients are women. Daniel Martínez Pérez holds tissue sample.

Even in late-stage Alzheimer’s, TSPO remained high in microglia near plaques. These results raise new questions about TSPO’s function – whether it contributes to damage or protects the brain – and whether blocking or enhancing it could halt disease progression. Next steps in research The team is now working with a specially developed Alzheimer’s mouse model lacking TSPO to explore these questions further. They’re also expanding the study to include sporadic, late-onset Alzheimer’s cases, the form that accounts for over 90% of all diagnoses. Researchers Dr. Tomás R.

Replacement Interstate 5 bridge inches towards construction

Oregon and Washington lawmakers were told Monday that final federal approval could be received early next year. Skeptics worry the $7.5 billion price tag will balloon.

A replacement for the Interstate 5 bridge across the Columbia River could get its final environmental and federal approvals early next year and move into construction shortly thereafter, planners told a joint committee of Oregon and Washington lawmakers on Monday.But questions remain about the overall cost of the project, toll rates, whether it will be a single span or a lift bridge, and whether the project will receive a final $1 billion in federal funding.The new bridge connecting Portland and Vancouver is officially expected to cost as much as $7.5 billion. But lawmakers from the two states pressed Greg Johnson, administrator of the Interstate Bridge Replacement Program, Monday whether that’s still a reliable estimate, given inflation that’s driving up the cost of major construction projects.Oregon lawmakers also said planners should have provided them an updated cost estimate before the special session on transportation that began Aug. 29 and is expected to conclude Wednesday.“It would be helpful if we could get that updated cost estimate as soon as possible,” said Sen. Khanh Pham, a Portland Democrat.Construction prices continue to rise.The replacement Francis Scott Key Bridge in Baltimore, for instance, was originally expected to cost $1.9 billion. It’s now expected to cost more than $5 billion.“We are seeing this type of inflationary spiral on major projects here in the Portland area as well as nationally,” Johnson said. “We are tracking what we are seeing all over. It is not a pretty picture.”As much as $1.6 billion of the replacement bridge’s cost will be paid for by tolling. As previously announced, tolls could range from $1.55 to $4.70, depending on several factors. They’re expected to start in the spring of 2027, a year later than first announced.Also unresolved is whether the center of the bridge will be able to lift to accommodate marine traffic. Coast Guard officials previously said a fixed bridge would be too low. If the Coast Guard ultimately requires a movable span, Johnson said, it will add an estimated $400 million to the project. He expects a decision from the Coast Guard early next year.The final $1 billion in federal funding for the new bridge also isn’t expected to be secured until 2028. During the public comment portion of the meeting, civic, business and construction groups mostly spoke in favor of the project, but critics continued to question the bridge’s cost.“A safe and modern bridge is an investment in Oregon and Washington’s future,” said Khanh Tran of the Oregon Chapter of the National Association of Minority Contractors, calling the project a “generational” opportunity for disadvantaged businesses.“I can’t tell you how frustrating it is to watch infrastructure this critical in nature being put off and put off and put off,” said Dee Burch, a director of the Oregon Columbia Chapter of the Association of General Contractors, who noted a replacement interstate bridge in Minneapolis got built in just over a year, although it was a significantly smaller project that cost $234 million. But critics, including economist Joe Cortright, with the Portland policy think tank City Observatory, said lawmakers need to contend with escalating costs that he expects will be “squarely in the $10 billion range,” telling lawmakers that would mean Oregon and Washington will each need to come up with another $1 billion in funding.Cortright also questioned whether the traffic assumptions on which tolling estimates are based are inflated and whether it’s prudent to count on the final $1 billion in federal funding, given ongoing cuts to the federal budget.“Federal funding is very, very much in doubt,” Cortright said, later calling it “reckless to embark on this project” when all the funding isn’t secured.The group of lawmakers, formally known as the Joint Interim Committee on Interstate 5 Bridge, will meet again in December.If you purchase a product or register for an account through a link on our site, we may receive compensation.

Santa Monica's waves have turned a bright pink. How can the dye job improve water quality?

Monday's pink, fluorescent dye drop in Santa Monica Bay is part of a project to study how water circulation could be driving poor water quality.

Over the next two weeks, surfers and beachgoers in Santa Monica may spot waves that have a pink, fluorescent hue — but officials say not to worry.The luminous, pink color spreading across the Santa Monica Bay is from a temporary, nontoxic dye that researchers are using to study how ocean circulation might contribute to the bay’s poor water quality. The project kicked off Monday morning, as UCLA and Heal the Bay researchers discharged the first of four batches of the pink dye near the Santa Monica Pier. “By following where the dye goes, we will better understand how the breakwater changes the environment around it, providing insight into Santa Monica beach’s poor water quality,” Isabella Arzeno-Soltero, an assistant professor of civil and environmental engineering at UCLA and a researcher on the project, said in a statement. Although the pink dye on Monday didn’t appear to create many “bright pink waves,” as researchers warned might be the case, additional bouts of the dye — or the fluorescent rhodamine water tracer dye — will be released later this month. But the fact that the dye seemed to dissipate quickly Monday didn’t mean the first phase won’t lead to important data, said Gabriela Carr, a researcher in the project and doctoral student at UCLA’s Samueli School of Engineering. “It was a big success today,” Carr said. “The dye is pink but it’s also fluorescent, so that’s kind of our main tracker.” A boat with “finely tuned fluorescent monitors” would remain in the bay for 24 hours, Carr said, and at least 10 additional trackers will remain attached to buoys through the end of the month, when additional dye drops will occur. The study is intended to help researchers understand how the man-made breakwater that was built in the 1930s in Santa Monica Bay, often visible during low tide, might hurt water circulation and, therefore, water quality. Santa Monica Pier routinely tops the yearly list of the state’s dirtiest beaches by environmental nonprofit Heal the Bay, which tests waters up and down the California coast for fecal bacteria, which can harm beachgoers. The break in the Santa Monica Bay was constructed to create a marina, but storms and time damaged it beyond effectiveness, though remnants of the rocky break still affect the water flow, researchers said.“It still substantially impacts the coastal hydrodynamics and surrounding environment,” Timu Gallien, an associate professor of civil and environmental engineering at UCLA and a lead researcher in the study, said in a statement. “For example, the breakwater protects the beach from large waves, keeping the beach wider than it would naturally be.”Santa Monica Mayor Lana Negrete watched the first deployment Monday morning and said she was hopeful this research could help her city finally get off the list of “beach bummers.” The city has partnered with the UCLA Samueli School of Engineering and the Bay Foundation on the project. “We’re trying to see if the circulation of the water is so poor that that’s creating the concentrated pollution 100 yards north and south of the pier,” Negrete said. “We don’t want to keep ending up on the beach bummer list — it’s a bummer!”She said this is one of many projects to help researchers understand and combat water quality issues, including a relatively new advanced water treatment facility and a sand dune restoration project. “This is all working in tandem,” Negrete said. “The whole ecosystem is important.”The researchers did not include in their announcement what remedies might be recommended if the breakwaters are determined to be responsible for, or a factor in, the poor water quality. That would probably be a multifaceted decision involving city and environmental leaders. Although this is the first time the dye has been used in the Santa Monica Bay, UCLA researchers said the coloring has been used for many years in other waterways, explaining that it disperses naturally and poses no risk to people, animals or vegetation.Carr said there may be more pink visible next week when the team performs another surface-level drop of the dye, but probably not as much when they do two deep-water drops later this month. Still, the pinkifying of the bay might not be much of a spectacle despite signs that were plastered all around the Santa Monica Pier area that scream: “Why is the water pink?” Carr said the team wanted to be sure the public did not become alarmed if the pink color was spotted. The next surface-level dye deployment will occur sometime Sept. 22–24, and the last underwater deployment will be Sept. 30, Carr said.

Portland rolls out $100M tree expansion, relaunches contract with Friends of Trees

New tree planting and tree care programs will launch this year, with funding via the Portland Clean Energy Community Benefits Fund.

The city of Portland is launching a major expansion of its citywide tree planting and tree care efforts, including restarting its relationship with the well-known nonprofit Friends of Trees. The initiative, announced Monday by Portland Parks & Recreation’s Urban Forestry division, aims to plant a total of at least 15,000 trees over the next three years, more than doubling Portland’s annual plantings, which currently stand at about 3,500 per year. Over 6,700 trees are planned for planting this coming season. The effort will be funded via $40 million from the Portland Clean Energy Community Benefits Fund, the climate justice fund seeded by a 1% tax on large retailers in the city. Urban Forestry is also launching pilot projects for two other programs via $70 million from the climate fund, including a street tree maintenance program and another program to provide free yard tree care services to low-income households. Portland has experienced a canopy decline in recent years, likely due to housing development and extreme weather. City officials have identified an imbalance of tree cover across the city – a problem, given that trees are the first defense against heat waves and bad air quality. The plan calls for the city to pay for planting 660,000 trees over the next 40 years, particularly on the far east side of Portland where lower income and many people of color live.To expand its tree planting, Urban Forestry will partner with 12 contractors and 13 community-based organizations, including Friends of Trees, the venerable Portland-based nonprofit that for more than a decade had brought together hundreds of volunteers to plant roughly 40,000 street trees all over Portland. That ended in 2022 after 14 years when the Portland Bureau of Environmental Services abruptly ended its $5.8 million planting contract with Friends of Trees, prompting protests from many Portlanders. The move came as Urban Forestry said it was developing its own tree-planting program instead. But the city seems to have partly gone back to the community planting model. Urban Forestry has just announced a $1.8 million partnership with Friends of Trees for planting 750 new street and yard trees in Portland over the next two planting seasons. The money also will pay for three years of care and watering for each tree planted. As before, the new contract with Friends of Trees will include intensive community outreach and volunteer training, with the first community planting event scheduled for Dec. 6. The nonprofit’s outreach includes sending thousands of multilingual, returnable postcards to residents in priority neighborhoods, delivering door hangers and flyers with signup info, tabling at community events and disseminating information through its expansive network of volunteers and community partners. The group also spreads the word about planting by hosting events like bilingual tree walks and tree-themed bike rides. Friends of Trees’ executive director Yashar Vasef said past differences with the city have been resolved. The nonprofit and Urban Forestry have recently partnered on other tree planting efforts, including a $12 million grant from the U.S. Department of Agriculture awarded to a Portland-area coalition as part of the Inflation Reduction Act, he said. “We’re really excited,” Vasef said. “This is going to look like our traditional model, with community members planting trees together.” Residents can, once again, request a tree from Friends of Trees and the organization will gather volunteers and engage them in mass plantings in different areas of the city. People separately also can request street trees on the city’s website. They also can receive up to three free trees to plant in their yard – but must plant the trees themselves. In addition to Friends of Trees, the other tree-planting contractors are: Bridgetown Construction and Landscaping, Pac Green Landscape, Seagraves Landscape, SymbiOp, Wyeast Gardens, A Plus Tree, Andres Landscape, Cascadian Landscapers, SaveATree, Super Trees and Multnomah Landscape. Additionally, the 13 partner organizations will provide multilingual outreach to help connect diverse communities with free trees. Some will assist with registering community members to sign up for free trees at in-person events and others will post program information on social media, in newsletters and through other channels of communication with particular communities. The other two programs starting up now will focus on tree care, with initial rollout and pilot projects planned for this fall and winter. The $65 million from the Clean Energy Fund will pay for Urban Forestry to develop a program to care for Portland’s street trees that will shift responsibility for maintenance away from adjacent property owners. And another $5 million will allow low-income households to qualify for free yard tree care and arboriculture-related technical mentorship from professional tree care providers. — Gosia Wozniacka covers environmental justice, climate change, the clean energy transition and other environmental issues.

Researchers Solve Decades-Old Color Mystery in Iconic Jackson Pollock Painting

Scientists have identified the origins of the blue color in one of Jackson Pollock’s paintings with a little help from chemistry

NEW YORK (AP) — Scientists have identified the origins of the blue color in one of Jackson Pollock's paintings with a little help from chemistry, confirming for the first time that the abstract expressionist used a vibrant, synthetic pigment known as manganese blue. “Number 1A, 1948,” showcases Pollock's classic style: paint has been dripped and splattered across the canvas, creating a vivid, multicolored work. Pollock even gave the piece a personal touch, adding his handprints near the top. The painting, currently on display at the Museum of Modern Art in New York, is almost 9 feet (2.7 meters) wide. Scientists had previously characterized the reds and yellows splattered across the canvas, but the source of the rich turquoise blue proved elusive.In a new study, researchers took scrapings of the blue paint and used lasers to scatter light and measure how the paint's molecules vibrated. That gave them a unique chemical fingerprint for the color, which they pinpointed as manganese blue. The analysis, published Monday in the journal Proceedings of the National Academy of Sciences, is the first confirmed evidence of Pollock using this specific blue.“It’s really interesting to understand where some striking color comes from on a molecular level,” said study co-author Edward Solomon with Stanford University.The pigment manganese blue was once used by artists, as well as to color the cement for swimming pools. It was phased out by the 1990s because of environmental concerns.Previous research had suggested that the turquoise from the painting could indeed be this color, but the new study confirms it using samples from the canvas, said Rutgers University’s Gene Hall, who has studied Pollock’s paintings and was not involved with the discovery.“I’m pretty convinced that it could be manganese blue,” Hall said.The researchers also went one step further, inspecting the pigment’s chemical structure to understand how it produces such a vibrant shade.Scientists study the chemical makeup of art supplies to conserve old paintings and catch counterfeits. They can take more specific samples from Pollock's paintings since he often poured directly onto the canvas instead of mixing paints on a palette beforehand. To solve this artistic mystery, researchers explored the paint using various scientific tools — similarly to how Pollock would alternate his own methods, dripping paint using a stick or using it straight from the can.While the artist’s work may seem chaotic, Pollock rejected that interpretation. He saw his work as methodical, said study co-author Abed Haddad, an assistant conservation scientist at the Museum of Modern Art.“I actually see a lot of similarities between the way that we worked and the way that Jackson Pollock worked on the painting," Haddad said.The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education and the Robert Wood Johnson Foundation.

Sweeping California climate bills heading to Newsom's desk

California state lawmakers gave their stamp of approval over the weekend to a slate of sweeping energy and climate-related bills, which will now head to Gov. Gavin Newsom’s (D) desk. The package's six bills — some of which passed with bipartisan support in an extended session on Saturday — marked a last-minute victory for Newsom, who negotiated the final terms of the legislation with State Senate and Assembly leaders over the past week. “We have agreed to historic reforms that will save money on your electric bills, stabilize gas supply, and slash toxic air pollution — all while fast-tracking California’s transition to a clean, green job-creating economy,” the governor said in a statement in the days leading up to the package’s passage. Within the package is a bill to increase the amount of climate credit appearing on utility bills, as well as another that would revive California’s ability to expand regional power markets via U.S. West clean energy. A third bill focused on improving utility wildfire safety by strengthening oversight and expanding a dedicated fund for wildfire readiness. The package also included an extension of the state’s cap-and-trade program, now to be known as “cap-and-invest.” This system, which sets emissions caps and distributes tradable credits within that framework, seeks to hold carbon polluters accountable by charging them for excessive emissions. Established by Republican Gov. Arnold Schwarzenegger in 2006, the program was set to expire in 2030 but would now be reauthorized until 2045, if signed into law. The fifth bill in the package centered on strengthening local air pollution reduction efforts and oversight by extending monitoring periods, redoubling the efforts of state and local air quality agencies to deploy effective strategies. A final piece of legislation, which received pushback from some progressive lawmakers, involved the stabilization of both in-state petroleum production and refinery supply, while also offering protections to communities located near wells. The Center for Biological Diversity slammed the passage of this bill, arguing that it was included “as a last minute ‘gut and amend’ measure at the end of the legislative session.” The bill, the organization warned, exempts oil drilling in California’s Kern County from state environmental quality requirements for the next decade, allowing for the approval of up to 20,000 new wells. “It’s senseless and horrifying that California just gave its seal of approval to this reckless ‘drill, baby, drill’ bill,” Hollin Kretzmann, an attorney for the center, said in a statement. Other environmental groups, however, voiced their support for the suite of climate-related bills, with the Natural Resources Defense Council (NRDC) commending the state for maintaining “its climate leadership.” NRDC staff members particularly praised the advancement of the cap-and-invest extension, as well as western grid regionalization and the wildfire protections. “While the Trump administration takes us backward, California will continue to address climate change, while improving affordability,” Victoria Rome, California government affairs director for the NRDC, said in a statement. “Our lives and prosperity depend on it.” In addition to the six-bill energy package, Newsom will also be receiving a selection of unrelated climate bills that received the legislature’s approval. Among those are first-in-the-nation legislation to require tests of prenatal vitamins for heavy metals, a public transportation funding bill and a plan to phase out toxic “forever chemicals” from cookware, food packaging and other consumer products. 

Shipping Companies Support a First-Ever Global Fee on Greenhouse Gases, Opposed by Trump Officials

Nearly 200 shipping companies said Monday they want the world’s largest maritime nations to adopt regulations that include the first-ever global fee on greenhouse gases to reduce their sector’s emissions

Nearly 200 shipping companies said Monday they want the world’s largest maritime nations to adopt regulations that include the first-ever global fee on greenhouse gases to reduce their sector’s emissions.The Getting to Zero Coalition, an alliance of companies, governments and intergovernmental organizations, is asking member states of the International Maritime Organization to support adopting regulations to transition to green shipping, including the fee, when they meet in London next month. The statement was shared exclusively with The Associated Press in advance. “Given the significance of the political decision being made, we think it is important that industry voices in favor of this adoption be heard,” Jesse Fahnestock, who leads decarbonization work at the Global Maritime Forum, said Monday. The forum manages the Getting to Zero Coalition.The Trump administration unequivocally rejects the proposal before the IMO and has threatened to retaliate if nations support it, setting the stage for a fight over the major climate deal. The U.S. considers the proposed regulatory framework “effectively a global carbon tax on Americans levied by an unaccountable U.N. organization,” the U.S. Secretaries of State, Commerce, Energy and Transportation said in a joint statement last month.U.S.-based shipping companies, however, have endorsed it. The Chamber of Shipping of America wants one global system, not multiple regional systems that could double charge vessels for their emissions depending on the route, said Kathy Metcalf, the chamber's president emeritus.In April, IMO member states agreed on the contents of a regulatory framework to impose a minimum fee for every ton of greenhouse gases emitted by ships above certain thresholds and set a marine fuel standard to phase in cleaner fuels. The IMO aims for consensus in decision-making but, in this case, had to vote. The United States was notably absent.Now nations have to decide if the regulations will enter into force in 2027. If agreed upon, the regulations will become mandatory for large oceangoing ships over 5,000 gross tonnage, which emit 85% of the total carbon emissions from international shipping, according to the IMO.If nations don't agree, shipping’s decarbonization will be further delayed and “the chance of the sector playing a proper and fair part in the fight to keep global heating below dangerous levels will almost certainly be lost,” said Delaine McCullough, president of the Clean Shipping Coalition and Ocean Conservancy shipping program director.The U.S. secretaries said in their statement that “fellow IMO members should be on notice” the U.S. will “not hesitate to retaliate or explore remedies for our citizens” if they do not support the United States, against this action. They said ships will have to pay fees for failing to meet “unattainable fuel standards and emissions targets,” driving up costs, and the fuel standards would “conveniently benefit China.” China is a leader in developing and producing cleaner fuels for shipping. While U.S. opposition and pressure cannot be taken for granted, it still appears as though a majority of countries currently support the regulations, said Faig Abbasov from Transport and Environment, a Brussels-based environmental nongovernmental organization. Abbasov said the deal reached in April was not ambitious enough, but this is an opportunity to launch the sector’s decarbonization and it can be strengthened.Shipping companies want the regulations because it gives them the certainty needed to confidently make investments in cleaner technologies, such as fuels that are alternatives to fossil fuels and the ships that run on them. In addition to the Getting to Zero Coalition, the International Chamber of Shipping, which represents over 80% of the world’s merchant fleet, is advocating for adoption when nations meet at IMO Headquarters in London from Oct. 14 to 17.

California Votes To Ban PFAS ‘Forever Chemicals’ in Cookware, Other Items

By I. Edwards HealthDay ReporterMONDAY, Sept. 15, 2025 (HealthDay News) — Every time you reach for a nonstick pan, you could be using chemicals...

MONDAY, Sept. 15, 2025 (HealthDay News) — Every time you reach for a nonstick pan, you could be using chemicals that are now on the chopping block in the state of California.Lawmakers have approved a bill to phase out PFAS — also called “forever chemicals” — in cookware, cleaning products, dental floss, ski wax, food packaging and certain children’s items.The proposal, Senate Bill 682, passed in a 41-19 vote and quickly cleared the state Senate. It now heads to Gov. Gavin Newsom, who has until Oct. 12 to sign it into law, CBS News reported.PFAS (per- and polyfluoroalkyl substances) have been widely used for decades, because they resist heat and water stains. But the chemicals build up in the body and environment and have been linked to cancers, liver and kidney damage and reproductive problems."Exposure to PFAS poses a significant threat to the environment and public health," the bill says.If signed, the law will roll out in stages: cookware must comply by 2030; cleaning products by 2031; and all other covered items by 2028.The plan has drawn sharp debate. Some chefs, including Rachael Ray, Thomas Keller and David Chang, argue that banning nonstick cookware made with PTFE (a type of PFAS better known as Teflon) could make cooking harder and more expensive for families, CBS News reported. “PTFEs, when manufactured and used responsibly, are proven to be safe and effective,” Ray, who sells a line of cookware bearing her name, wrote in a letter to lawmakers.But environmental groups, including the Natural Resources Defense Council, say nonstick pans can release PFAS particles when scratched or overheated. Actor Mark Ruffalo also urged support for the bill. "Independent science shows that the PFAS in cookware can wind up in our food," he wrote on X.State Sen. Ben Allen proposed the legislation.“PFAS pose a level of serious risks that require us to take a measured approach to reduce their proliferation and unnecessary use,” he said.California has already banned PFAS in items like carpets, firefighting foam and cosmetics. If signed into law, SB 682 would make California one of the first states to phase out PFAS in cookware.The U.S. Environmental Protection Agency has more on PFAS.SOURCES: CBS News, Sept. 13, 2025; California Legislative Information, Sept. 9, 2025Copyright © 2025 HealthDay.

The Exotic Pet Trade Harms Animals and Humans. The European Union Is Studying a Potential Solution

EU legislators are considering a form of regulation that could protect many species from unsafe exploitation — if it’s done right. The post The Exotic Pet Trade Harms Animals and Humans. The European Union Is Studying a Potential Solution appeared first on The Revelator.

By the time a sugar glider named Mango entered an animal sanctuary in the Netherlands in 2023, life as a pet had taken a terrible toll. Mango lost both his brothers and his right eye due to health issues, despite being kept by a veterinarian for seven years. These days, Europeans keep tens of millions of exotic pets — as do people in other countries around the world.  Although beloved by their owners, experts say most of these animals, like Mango, do not adapt well to life in captivity and often face health problems and premature death as a result of this legal trade. Mango the sugar glider. Courtesy Animal Advocacy and Protection Globally, the business involves an estimated 13,000 species, many unsuited to being companion animals, says Michèle Hamers, EU policy officer at the nonprofit Animal Advocacy and Protection. The organization runs the sanctuary where 9-year-old Mango lived — alongside fellow sugar gliders Radagast, Didache, Duizeltje, and Sushi — until his sudden death on July 21, likely from a hematoma. “Something needs to change,” says Hamers. For her organization, that change would involve the introduction of an EU-wide “positive list” for exotic pets — a limited inventory of approved pet species suited to captivity. They’re not the only ones asking for this. In recent years, momentum has grown toward making this a reality. The Pet Trade in Europe Sugar gliders are marsupials native to Australia, Indonesia, and Papua New Guinea named for their ability to “glide” through the air between trees on fleshy membranes connecting their front and back legs. Their arboreal, nocturnal lifestyles are among the traits that make them unsuitable for living in a cage in someone’s house, Animal Advocacy and Protection says. By their very nature of being wild, many other species don’t do well in captivity. As a result, the nonprofit’s rescue centers in the Netherlands and Spain take in as many exotic pets as they can. It’s never enough: they typically have a waiting list in the hundreds. Hamers says relinquished or seized animals typically arrive with behavioral and physical problems, including bone malformations, malnutrition, and stress-related issues like self-mutilation.

Hamers says this would establish a selective list of animals who can be kept, with all others banned by default. This type of system is known as positive, reverse, or whitelisting. Only animals who “can thrive in captivity and are safe to be kept” should make the cut, explains Hamers. Presently, the EU has no regulation designed to address the pet trade, although the market sometimes falls under laws concerning animal health, “invasive alien” species, and trade in threatened wildlife. Mostly, though, member states decide their own rules on exotic pets, which can vary greatly from country to country. Some EU nations don’t regulate the exotic pet trade at all, while others use a negative list system, meaning they create lists of banned species. The remaining member states — 12 out of 27 — have some form of positive list in place or the legal basis to develop them, says Hamers. In recent years European lawmakers have signaled support for an EU-wide positive list through varied resolutions and action plans. As a result the European Commission, which is the bloc’s executive body, commissioned a study on its feasibility in late 2023. The results are due later this year. On June 19, as part of a proposed regulation on the trade in pet cats and dogs, the European Parliament also voted in favor of establishing an EU-wide positive list for exotic pets, providing that the feasibility study shows the measure to be valuable and legally possible. One Trade, Many Problems In the proposed regulation, EU lawmakers warn that “the absence of a common Union framework” leads to “inconsistencies, gaps in enforcement, confusion for consumers and, often, to serious animal welfare consequences for species that are unsuitable to be kept as pets, as well as risks to biodiversity, human health and safety and nature conservation.” This statement illustrates why support for a positive list is gaining steam: the exotic pet trade is associated with several problems, not solely animal welfare. For Animal Advocacy and Protection, the welfare of kept animals is a priority. Whether captivity can meet animals’ physical and psychological needs should be the main criteria for considering who gets on the list, says Hamers. But, she adds, the criteria should include other factors, such as risks to biodiversity and public health and safety. A 2021 report by nonprofits Born Free and the RSPCA highlighted the potential risks exotic pets pose to public health. They include injuries and transmission of zoonotic pathogens: diseases like Covid-19 that can be passed between humans and other animals.

Hundreds of imported species have ended up being released into the wild, sometimes with dire consequences for native wildlife. For instance, scientists have implicated the trade in live amphibians for pets and meat in the global spread of the disease chytridiomycosis, which is linked to widespread amphibian population declines and 90 documented extinctions. On the flip side, trade can pose a threat to exploited species themselves. Scientists have calculated that 25% of the over 800 amphibian species traded as pets are threatened. They said further regulation and other measures are “urgently needed to slow the decline of populations and loss of species as a consequence of unsustainable, and largely unmonitored trade in wildlife.” Likewise, the industry is notorious for scooping up newly described species, often ones with limited ranges, to support collectors’ voracious desire for novelty. Positive lists could help to nip this unscrupulous inclination in the bud, because commerce in such species would be banned by default. Exotic pets are both sourced from the wild and bred in captivity. Breeding operations can relieve pressure on wild populations. But they can also be associated with illicit activity, such as the laundering of wild-caught animals into the captive-bred trade. In 2019, Belgium’s federal body for health, food chain safety, and environment, pointed to further links between captive breeding and illegality in a factsheet about the live amphibian trade. It stated, “illegal specimens are assumed to be the founding stock for many captive specimens, including within the European Union.” Illegal trade is a significant issue in the exotic pet business. A report by Traffic highlighted that 28% of all animals seized by EU countries in 2023 were likely destined to be pets, amounting to some 3,500 individuals. The lack of uniform regulation across the EU is a “massive problem” in this regard, says Hamers. Market fragmentation in a free trade bloc creates a ripe environment for illegal trade, she explains, because people can purchase animals banned in their own country from other EU states with relative ease. The United States has the same issue. In a 2023 paper, researchers noted that state and local regulations govern much of the trade, despite federal rules having some bearing on it, such as the Lacey Act’s prohibitions on the importation of certain “injurious” species. Differing and incomplete rules across states, alongside lackluster penalties for wrongdoing, have “facilitated continued possession of exotic pets in states where these animals are banned,” the researchers warned. They concluded the U.S. would benefit from a nationwide positive list system, too. Making Positive Lists Meaningful Even with captive breeding, many exotic pets being traded across the EU and the U.S. originated from countries elsewhere, says Peter Lanius, director of the Australian nonprofit Nature Needs More. Lanius’ organization released a report in June outlining how a global positive list for exotic pets could be introduced by the global wildlife trade treaty body, the Convention on International Trade in Endangered Species of Wild Fauna and Flora. Alongside yardsticks like considering species’ welfare needs and mortality rates in captivity, it argues that a determining factor should include whether trade is easy to monitor.   View this post on Instagram   A post shared by ShaldonZoo (@shaldonzoo) This ties to the report’s broader theme: the importance of establishing a robust regulatory architecture around positive lists, which the authors say is generally lacking even for the few that already exist. Pet industry advocates have described existing lists in European countries and elsewhere as “unenforceable,” the report notes. “If you stop at the point where you just list what can be traded, but there’s no infrastructure… it’s symbolic, not practical,” insists Lynn Johnson, Nature Needs More’s founder and CEO. Positive lists must be accompanied by “dedicated monitoring and enforcement capacity,” according to the report. Nature Needs More also calls for businesses to be registered, licensed, and required to provide end-to-end traceability for the animals they trade. Owners should be required to register exotic pets too, the report says, with the veterinary profession engaged in maintaining care standards. Other outlined provisions include creating a listing authority to determine and perpetually review the positive list, as well as interventions to reduce consumer demand for banned species. The organization also calls for legislation to compel social media companies to police commerce on their sites by making them liable for traded animals. The organization says financing these provisions should come from a business levy on traders. None of these ideas are revolutionary, the nonprofit stresses. Nations have imposed similar regulatory measures on the pharmaceutical and chemical industries. But the model would be a massive step for the wildlife trade, which typically lacks adequate monitoring and enforcement. A Trivial Trade in Living Beings This January the European Pet Organization — which bills itself as “the voice of the pet sector at European level” — released a position statement on positive lists. In contrast to ornamental fish trade veteran Tim Haywood, who told The Revelator last year that the number of species in the pet fish trade must shrink, the pet organization rejected the idea of “restrictive measures” such as positive lists. The group suggested poor welfare and illegality in the trade are limited and could be dealt with through improved enforcement of existing legislation and education of consumers. It also argued that restricting petkeeping through positive lists wouldn’t stop determined owners from buying forbidden exotic animals. However, a Finnish study found that many hobbyists are put off from buying exotic pets when the animals are subject to trade restrictions. Hamers has further reason to doubt that a positive list system will lead to significant rises in illegal petkeeping. The trade is “hyper-commercialized,” she explains, and “many purchases are done on the whim,” often driven by popular culture trends like movies or social media. “Once species aren’t for sale anymore through common channels, the possibility to buy an animal on an impulse also disappears,” says Hamers. For Nature Needs More, the often-trivial nature of modern-day pet purchasing makes positive listing so necessary. Although the keeping of exotic pets has occurred for centuries, substantially more people can casually engage it now due to having the money, time, and access to animals in “our globalized, industrial society,” its report says. “When a trade in living beings is allowed to function by the rules of the throw-away consumer society, then we have a serious problem,” the organization warns.
