This Supreme Court Term, Health and Safety Are on the Line

News Feed
Tuesday, May 28, 2024

In the coming weeks, the Supreme Court will release several opinions that implicate the health and safety of every American. Citizens may believe that the court’s decisions are far removed from their everyday lives. But this term, at least, they will hit close to home. From the environment, to medical care, to the hot-button issues of guns and abortion, over the past year the court took up a string of cases that will affect how well we live—and how long.  The vast and critically important implications of these coming rulings pose a key question: Should judges be the ones deciding the rules and regulations that so intimately affect Americans’ lives? In case after case, the court is contemplating overruling decisions made by Congress and administrative agencies to protect Americans’ safety. One of the most critical cases this term raises that very issue: who in government gets to decide detailed questions about our medical care, drug safety, chemicals in the air and water, food safety, and much more? It’s likely that in a pair of cases this term, the justices will decide that the best people to make those decisions are unelected judges—and ultimately, the justices themselves. The Chevron case puts thousands of regulations related to Americans’ health and safety at risk. In a set of cases challenging a fishing regulation, the justices are considering whether to end or limit a principle of judicial decision-making called Chevron Deference, under which judges defer to administrative agencies if the law is ambiguous and the agency interpretation is reasonable. The rule was enshrined in the 1984 case Chevron v. National Resources Defense Council, but “this practice of deferring to reasonable agency interpretations of ambiguous statutes was well established in the case law handed down by the Supreme Court” by the mid-1940s, says Miriam Becker-Cohen, an appellate counsel at the liberal Constitutional Accountability Center.  The case implicates thousands of regulations promulgated every year, many having to do with Americans’ health and safety. In an amicus brief, the American Cancer Society warned that deference is critical to the administration of Medicaid, Medicare, and the Children’s Health Insurance Program, which together provide healthcare to nearly half the US population. Agency experts, they argued, are best positioned to interpret statutory terms like “geographic area,” “costs incurred,” and “nursing-related services.” Given the amounts of money spent on health care, without Chevron, litigation would abound. “The resulting uncertainty would be extraordinarily destabilizing, not just to the Medicare and Medicaid programs but also—given the size of these programs—to the operational and financial stability of the country’s health care system as a whole,” the brief warns. The effects of sunsetting Chevron would go far beyond healthcare. Civil rights groups warn that laws protecting minorities in housing, employment, and financial services could be gutted by newly-empowered judges. Agencies, guided by scientists and other experts, work to protect Americans from toxic chemicals, to keep air and water clean, maintain food safety, and on and on. “Is a new product designed to promote healthy cholesterol levels a dietary supplement, or a drug?” Justice Elena Kagan asked during oral arguments, raising just one hypothetical question that, if Chevron were overruled, might transfer from doctors to judges. With changes this broad, everyone’s safety would be implicated. “When the administrative state falls into a sinkhole, or quicksand, because of this court,” Georgetown Law professor Michele Goodwin warns, it will impact how people “actually have a healthy and, in fact, even joyful life.” Guns are another issue critical to Americans’ health and safety. In 2017, a gunman used semi-automatic rifles equipped with bump stocks to fire on concert-goers in Las Vegas. A bump stock is a firearm accessory that turns a semi-automatic rifle into a continuously firing weapon that discharges dozens of bullets in seconds. In 11 minutes, the shooter struck 500 people, killing 60—the deadliest mass shooting in the country’s history. In the aftermath, the Bureau of Alcohol, Tobacco, and Firearms banned bump stocks by defining them as illegal machine guns. In Garland v. Cargill, the justices are weighing whether to overturn that decision. Such a ruling by the court would allow Americans to own, for all intents and purposes, automatic weapons. One need only look to Las Vegas to understand the cases’ significant potential to impact Americans’ health and safety.  Lawmakers say ending the bump stock ban would “shackle” Congress’ ability to keep people safe. In a second major gun case, the justices are considering whether a federal law barring firearm possession by people subject to domestic violence restraining orders violates the Second Amendment’s right to bear arms. Victims of domestic abuse rely on the law to survive. “As one study found, the risk of intimate-partner homicide increases 500% when abusers have access to a firearm,” an amicus brief submitted by domestic violence prevention groups states. “Another determined that an average of seventy (70) women are shot and killed by intimate partners per month.” When Congress decided to ban gun possession by abusers in 1994, it had found that domestic violence was “the leading cause of injury to women in the United States between the ages of 15 and 44,” and that “firearms are used by the abuser in 7 percent of domestic violence incidents.”  In a brief submitted by Democratic members of Congress, lawmakers argued that invalidating the ban would “shackle” Congress’ ability to keep people safe, and render it “unable to develop innovative solutions for the benefit of the public.” Moreover, they warn, such a decision would “generate a wave of litigation” challenging other public safety-minded gun restrictions “that will burden the courts and hamper legislatures’ ability to address public safety needs.” Public health and safety are closely tied to the environment. This term, the court heard a challenge to an EPA rule intended to protect against air pollution under the Clean Air Act. The case involves the legality of the Good Neighbor provision, which protects downwind states from harmful pollution originating in upwind states. According to the EPA, the rule will “improve air quality for millions of people living in downwind communities, saving thousands of lives, keeping people out of the hospital, preventing asthma attacks, and reducing sick days.” In 2026 alone, the agency estimated that the rule would prevent around 1,300 premature deaths and 2,300 hospital and emergency room visits, cut asthma symptoms by 1.3 million cases, and eliminate 430,000 school absence days and 25,000 lost work days. But after oral arguments in February, the court’s Republican-appointed majority appeared ready to block the provision. The case arrived at the court following a complex series of lawsuits, and the justices agreed to hear the challenge on an emergency basis, short-circuiting the lower courts. Should the Supreme Court decide to halt the EPA’s rule, it will have gone out of its way to impede environmental safety when the issue could have been left to the normal judicial process. In 1986, Congress passed the Emergency Medical Treatment and Labor Act (EMTALA), to stop hospitals from “dumping” uninsured or poor patients who showed up in need of emergency care. In 2022, Idaho banned all abortions unless the mother’s life was at risk. This conflicted with EMTALA, which requires an abortion when it is the necessary treatment to stabilize a health emergency, even when the mother’s life isn’t immediately in peril. Now, the Supreme Court is deciding whether states can subject pregnant women to undergo severe medical crises—up to and including death—in their radical crusade to end abortions. The court is deciding whether states can subject women to medical crises—including death. The effects of abortion bans on women’s health are already apparent two years after the Supreme Court overturned Roe v. Wade. The EMTALA case is about the most extreme examples: people whose safety, bodily organs, and lives are in danger yet are being denied care as a result of state abortion bans. Already, stories of women hemorrhaging in bathrooms, spending days in the ICU, and being airlifted across state lines fill the news. Failure to provide an abortion in critical cases can lead to loss of the uterus, kidney failure, stroke, hemorrhage, and death. This is a health emergency created by the Supreme Court—and if oral arguments are an indication, it will only worsen when it rewrites federal law to remove the right to emergency abortion care for pregnant people. The EMTALA case is not the only abortion case the court is deciding. The other centers on access to mifepristone, one of two drugs used in medication abortions, which, after Roe, have become the most common way to end a pregnancy. In order to stop them, a group of pro-life doctors argued that the FDA improperly okayed the drug more than two decades ago. For technical legal reasons, the justices appear unlikely to limit access to the drug this term. But the case is likely to return on stronger footing soon, and whatever its disposition, the threat such attempts represent to public health is enormous: access to safe abortions improve health and economic outcomes for women, while bans imperil women’s health.  In each of these cases, the court is contemplating doing serious harm to health and safety by undoing an action by Congress or agency experts regulating at the behest of Congress, shifting control over life and death decisions from the elected branches of government to the courts. Perhaps the most terrifying phrase about today’s government is: I’m a Supreme Court justice and I’m here to help.

Why Polio Has Reemerged in Gaza

After a quarter of a century, the disease has returned to Gaza, prompting a campaign to immunize all of the territory's children against the virus.

THIS ARTICLE IS republished from The Conversation under a Creative Commons license.A 10-month-old boy in the Gaza Strip was recently paralyzed by poliovirus—the first such case in the region this century. Israel and Hamas have agreed to a limited ceasefire to allow 640,000 children in the enclave to be vaccinated against the virus. We asked a virologist to explain how the virus emerged in the region after all this time, and how it will be dealt with.The Conversation: Given that polio was all but eradicated in this region of the world, how might the 10-month-old baby in Gaza have caught it?Lee Sherry: The sequences of the polioviruses detected in Gaza in July 2024 suggest that these viruses may be related to a strain circulating in Egypt, with the virus potentially being introduced to Gaza as early as September 2023.This is probably due to the nature of the oral poliovirus vaccine (OPV), which contains a weakened live poliovirus that can be shed by vaccinated people. This suggests the virus may have been introduced by someone traveling to the region.The war in Gaza has also provided an ideal environment for the virus to thrive and spread, due to the unhygienic conditions caused by little access to clean water and sanitation.Can the virus “survive” (remain viable) for long periods without a human host?Yes, poliovirus is an incredibly stable virus that can remain infectious for long periods outside of the human body, depending on the environmental conditions. For example, polioviruses are capable of surviving in groundwater for several weeks.Can you explain what “wild type” poliovirus is, compared with vaccine-derived “variants”?Wild type poliovirus is a virus that is circulating naturally in the environment, whereas vaccine-derived strains are related to the weakened virus present in the OPV, which in extremely rare cases is capable of reverting to a form capable of causing paralysis.Is the wild type still endemic anywhere in the world?Due to the success of the Global Polio Eradication Initiative, led by the World Health Organization, that began in 1988, type 2 and type 3 polioviruses have been declared eradicated. Only type 1 poliovirus is currently circulating in Afghanistan and Pakistan, where there have been 27 recorded cases so far in 2024.A health worker marks the finger of a Palestinian child vaccinated against polio in Deir Al-Balah in the central Gaza Strip.

Why a bill to regulate California warehouse development is generating sweeping opposition

A bill on Gov. Gavin Newsom's desk would set standards for industrial warehouse development near homes and schools. Opponents say those standards are weak and won't lessen health risks for residents living in the shadow of e-commerce.

Xochitl Pedraza moved to San Bernardino County eight years ago. After three decades of city living, unincorporated Bloomington offered a rural community where she could buy an acre of land and raise chickens.But Pedraza’s neighborhood has become more industrial in recent years, as developers have converted large swaths of property along the 10 Freeway into a logistics corridor for e-commerce, connecting goods shipped into Southern California ports with online shoppers across the nation. While proponents of the developments say they bring jobs and infrastructure improvements, many residents living in their shadow lament the pollution, traffic and neighborhood disruption.There was already an avocado distribution center across the street from Pedraza’s home; now there’s an Amazon fulfillment center on the corner that brings “trucks after trucks after trucks,” Pedraza said. The incessant beeping and honking penetrate her soundproof windows.She and her 8-year-old grandson suffer from dry eyes, nasal congestion and a chronic dry cough — symptoms she attributes to dust from warehouse construction and the region’s ozone pollution. A bill on Gov. Gavin Newsom’s desk would establish siting and design standards for industrial warehouses that, according to supporters, would better protect the health of residents such as Pedraza. Assemblymember Juan Carrillo (D-Palmdale), who co-authored the legislation, has described the measure as a “very delicate compromise” that resulted from lengthy negotiations among a working group that included labor, health, environmental and business representatives. Nonetheless, the bill has generated staunch opposition from a diverse range of environmental, community and civic groups statewide who object to the secrecy in which the bill was crafted in the final days of session and who say it fails to hold warehouse developers to higher standards.Beginning in 2026, AB 98 would prohibit cities and counties from approving new or expanded distribution centers unless they meet specified standards. New warehouse developments would need to be located on major thoroughfares or local roads that mainly serve commercial uses. And warehouse sites would need to be set back several hundred feet from so-called “sensitive sites” such as homes, schools and healthcare facilities. Additionally, if a developer demolishes housing to make way for a warehouse, the bill would require two new units of affordable housing for each unit that is destroyed. The developer would have to provide displaced tenants with 12 months’ rent.Some regulations would need to be enacted in the state’s “warehouse concentration region” — Riverside and San Bernardino counties and a dozen Inland Empire cities — by 2026, two years before the rest of the state.While some labor groups support the bill, it is opposed by a host of environmental, business and community organizations. Several cities also opposed the legislation, which according to an analysis by the Senate Appropriations Committee, requires general plan updates that could result in one-time costs for cities and counties ranging from tens of millions to potentially hundreds of millions of dollars. Environmental advocates are especially concerned about the bill’s setback requirements for projects involving warehouses 250,000 square feet and larger that are within 900 feet of homes, schools, parks or healthcare facilities.In those cases, the bill would require that truck loading bays are located at least 300 feet from the property line in areas zoned for industrial use; and 500 feet from the property line in areas not zoned for industrial use. Warehouses would also need to comply with design and energy efficiency standards.Pedraza, the Bloomington resident, said the distances laid out aren’t enough buffer. The rules also don’t take into account that truck traffic and pollution issues are magnified in overburdened communities such as Bloomington, she said.“The whole community is surrounded by warehouses now,” she said. “It doesn’t matter how far it is ... they still affect us.”The bill would simply enshrine current warehouse development practices into law and undermine local efforts to advocate for the much bigger setbacks recommended by state agencies, said Andrea Vidaurre, senior policy analyst for the People’s Collective for Environmental Justice in San Bernardino.In a 2022 report on best practices for warehouse projects under the state’s environmental laws, the state attorney general’s office recommends locating warehouse facilities so that their property lines are at least 1,000 feet from the property lines of sensitive sites such as homes and schools. It cites the state Air Resources Board, which in 2005 estimated an 80% drop-off in pollutant concentrations at approximately 1,000 feet from a distribution center.“If this is signed into law, we’re basically saying, ‘Business as usual is okay; let’s keep building it like this,’” Vidaurre said. “We’re going to continue to see warehouses being put across the street from homes and schools, because it will be OK with the law.”Assemblymember Eloise Gomez Reyes (D-Colton), another co-author, acknowledged during a Senate committee hearing last week that AB 98 preserves jobs and enacts warehouse standards but is “not the perfect bill.”She introduced a bill earlier this year that said warehouses could be sited within 1,000 feet of schools, homes, healthcare facilities and other sensitive sites only if they included a minimum setback of 750 feet and adopted specific mitigation measures. The bill was held in its first committee.Gomez Reyes said the distance requirements in AB 98 could serve as a floor.“I do not believe the sensitive receptor setbacks in this bill adequately protect our most vulnerable communities,” Gomez Reyes said during the hearing. “It is important to note that these, however, are only a minimum. And nothing in this bill stops cities or advocates from pushing to put in place stronger standards with local cities and counties.”Karla Cervantes launched the Mead Valley Coalition for Clean Air earlier this year to fight the proliferation of warehouses in her unincorporated community of about 20,500 people in Riverside County. She said developers aren’t going to agree to setbacks larger than what’s required in the legislation. Riverside County already recommends warehouses be designed so there’s at least 300 feet between the property line of a sensitive site and the nearest dock door. While it is “very rare” for developers to agree to a larger setback, she said, they will sometimes offer larger landscaped buffers to obscure people’s view of facilities.If AB 98 becomes law, she said, “it’s going to be even harder for us to try to push for better.”Newsom has until Sept. 30 to sign or veto the bill.This article is part of The Times’ equity reporting initiative, funded by the James Irvine Foundation, exploring the challenges facing low-income workers and the efforts being made to address California’s economic divide.

Air quality alert issued for Klamath and Lake counties

On Friday at 11:13 a.m. an air quality alert was issued for Klamath and Lake counties.

On Friday at 11:13 a.m. an air quality alert was issued for Klamath and Lake counties.According to the National Weather Service, "Oregon Department of Environmental Quality has issued an Air Pollution Advisory in effect until noon Monday.This air quality advisory covers northern Lake and northern Klamath counties due to wildfires burning in the region. The DEQ also expects intermittent smoke in central and eastern Douglas County and Jackson County through this period due to smoke from surrounding fires.The wildfire smoke combined with forecast conditions will cause air quality levels to fluctuate and could be at unhealthy levels.Smoke levels can change rapidly depending on the weather and planned burn operations. Smoke can irritate the eyes and lungs and worsen some medical conditions. People most at risk include infants and young children, people with heart or lung disease and older adults.People can take the following precautions to protect their health:- Follow local burn restrictions to prevent deteriorating air quality.- Avoid strenuous outdoor activity during periods of poor air quality.- People with heart or lung problems and young children are especially vulnerable. These people should stay indoors while smoke levels are high.- Use certified High Efficiency Particulate Air (HEPA) filters in indoor heating, ventilation, cooling and air purification systems.- Avoid using wood-burning stoves and other sources of indoor smoke if possible."

Too Much Light at Night Linked to Higher Alzheimer's Risk

By Dennis Thompson HealthDay ReporterFRIDAY, Sept. 6, 2024 (HealthDay News) -- People who live in areas with more nighttime light pollution could be at increased risk of Alzheimer’s disease, particularly those in middle age, a new study says.Nightly light pollution is more strongly linked to Alzheimer’s disease in people 65 and older than other known risk factors like alcohol abuse, kidney disease, depression and obesity, researchers reported Sept. 5 in the journal Frontiers in Neuroscience.And light exposure poses an even greater risk to the brains of people younger than 65.High nighttime light intensity was the top risk factor for early-onset Alzheimer’s in that age group.“We show that in the U.S. there is a positive association between Alzheimer’s disease prevalence and exposure to light at night, particularly in those under the age of 65,” said lead researcher Robin Voigt-Zuwala, an associate professor at Rush University Medical Center in Chicago.“Nightly light pollution -- a modifiable environmental factor -- may be an important risk factor for Alzheimer’s disease,” Voigt-Zuwala added in a university news release.For the study, researchers analyzed light pollution maps for the 48 continental states, comparing them to national data about Alzheimer’s disease incidence and known risk factors for the degenerative brain disease.Light pollution appears to be an Alzheimer’s risk factor for seniors, but it is not as strong an influence as other factors like diabetes, high blood pressure and stroke, results show.But no other risk factor outpaced light pollution for those younger than 65, researchers found.The results suggest that younger people might be particularly sensitive to the effects of light exposure at night, although it’s not clear why, researchers said.Genetics that increase a person’s risk for early-onset Alzheimer’s “impact the response to biological stressors, which could account for increased vulnerability to the effects of nighttime light exposure,” Voigt-Zuwala theorized. “Additionally, younger people are more likely to live in urban areas and have lifestyles that may increase exposure to light at night.”Given these findings, people might want to limit their exposure to bright lights at night, the researchers said.“Easy-to-implement changes include using blackout curtains or sleeping with eye masks,” Voigt-Zuwala said. “This is useful especially for those living in areas with high light pollution.”Light exposure inside a home could be just as important, the researchers added. People should limit their exposure to blue light, which can affect sleep, and install dimmers in their home.SOURCE: Rush University Medical Center, news release, Sept. 6, 2024Copyright © 2024 HealthDay.

The astonishing link between bats and the deaths of human babies

There are a number of well-known ways to keep babies healthy — wash your hands often, get them vaccinated, don’t smoke inside, and so on.  But there’s one thing you probably haven’t heard of: protecting bats. Like literal flying bats.  That’s one takeaway from a remarkable new study, published in the journal Science, that links the […]

A little brown bat, one of a dozen species in North America that is susceptible to a wildlife disease called white nose syndrome. | Bob Pool/Getty Images There are a number of well-known ways to keep babies healthy — wash your hands often, get them vaccinated, don’t smoke inside, and so on.  But there’s one thing you probably haven’t heard of: protecting bats. Like literal flying bats.  That’s one takeaway from a remarkable new study, published in the journal Science, that links the decline of bats to a rise in newborn deaths in the United States. By compiling and analyzing a huge amount of government data, environmental economist Eyal Frank, the study’s sole author, discovered that in regions where white nose syndrome, a wildlife disease that impacts bats, has hit particularly hard, the rate of infant mortality increased by nearly 8 percent. There’s a clear reason for this, according to the paper. Most North American bats eat insects, including pests like moths that damage crops. Without bats flying about, farmers spray more insecticides on their fields, the study shows, and exposure to insecticides is known to harm the health of newborns.  “When bats that eat insects go down, farmers compensate by using more insecticides,” Frank, an assistant professor at the University of Chicago Harris School of Public Policy, told Vox. “That has adverse health consequences — full stop. The damages from their absences appear to be substantial.” Frank’s study adds to a growing body of research that supports the idea — which perhaps should be obvious by now — that healthy ecosystems are important for human well-being. Earlier research has found that wolves help limit car accidents by keeping deer off the road. Other research, also led by Frank, links the sudden decline of vultures in India to an increase in human death rates. Vultures eat animal carcasses that, if left to rot, can pollute waterways and feed feral rats and dogs, a source of rabies. When the link between human and environmental health is overlooked, industries enabled by short-sighted policies can destroy wildlife habitats without a full understanding of what we lose in the process. This is precisely why studies like this are so critical: They reveal, in terms most people can relate to, how the ongoing destruction of biodiversity affects us all.   When bats disappear, farmers spray more Not everyone finds bats cute — they are! — but they are undeniably impressive. They’re the only mammal on earth that can truly fly. Plus, they eat astounding quantities of bugs. A single bat can catch several hundred insects an hour, and thousands in a single night. This is good for us: Many of the critters that bats consume during their nightly hunt are insects that we don’t like, such as blood-sucking mosquitos and crop-eating moths and beetles. Bats are, essentially, a natural pest control. So it stands to reason that without bats, farmers have to use more insecticides on their crops; agrochemicals do the job that bats do for free. There hasn’t been a great way to test that theory, until somewhat recently, when bats across North America began dying en masse. In 2006, a fungal disease called white nose syndrome appeared in New York state and began spreading among bat colonies, killing an average of more than 70 percent of the bats within them. It’s been brutal. WNS invades their skin, producing fluffy white growths around their noses, and wakes them up during hibernation when they should be resting. Infected bats burn off vital energy stores and either freeze or starve to death.  Devastating as it may be, the rapid loss of bats has provided researchers with a rare opportunity to test what happens when these animals disappear from the landscape. In the new study, Frank — who works at the intersection of economics and conservation — analyzed data on pesticide use across US counties with and without WNS, which until recently were mostly in the eastern US. Where there’s WNS, there are presumably far fewer bats.  His results were astonishing: Farms in regions hit by WNS used 31 percent more insecticides on their crops, compared to counties without the disease. That suggests that when bats disappear, farmers compensate by using more chemical bug killers.  At what cost? The alarming consequences of losing bats First, there is a cost to farmers. According to Frank’s study, the decline of bats has cost the agriculture industry nearly $27 billion between 2006 and 2017, as shown by a drop in revenue in regions with white nose syndrome. The reason for this loss is not clear, though it might be that bat-free regions produce lower quality crops, Frank said. A study published in 2022 supported a similar conclusion, linking the spread of WNS to a drop in the rental price of farmland. The idea is that farmers have a lower yield or have to spend more money to grow crops — such as on purchasing insecticides — when there are no bats providing free pest control. (I interviewed one of the study co-authors, Amy Ando, for an episode of the Vox science show Unexplainable. You can listen here.) Then there is the serious cost to human lives. It’s well-known that when farmers spray their fields with insecticides, those chemicals can leach into the environment, where they pose a risk to public health. One recent review links pesticide exposure among newborns, for example, to life-long abnormalities and diseases. With this in mind, you might expect regions with no bats, where farmers are using more insecticides, to have more health issues.  Frank tested this theory too, using government data on infant mortality, overlaid with the spread of white nose syndrome. The results of his analysis were alarming: The rate of internal infant mortality — babies who have died by causes other than accidents or homicides — increased by nearly 8 percent in counties following WNS outbreaks. Put another way, when insecticide use increases by 1 percent, infant mortality increases by a quarter of a percent, which is comparable (though slightly lower) to the impact of ambient air pollution.  “I was surprised that the signal [in the data] was so strong,” said Dale Manning, an environmental economist at the University of Tennessee Knoxville, who was not affiliated with the study. “They’re big, big numbers in terms of monetary impacts, but we’re also talking about human lives, right? And so those impacts are pretty substantial.” The rate of internal infant mortality increased by nearly 8 percent in counties following white nose syndrome outbreaks Manning and Ando, an environmental economist at Ohio State University who also was not involved in the study, said the paper’s conclusions were sound. (Ando and Manning were both involved in the 2022 study, mentioned above.)  While the research doesn’t definitively prove that bat declines cause insecticide use and infant mortality to increase, the study ruled out many other potential forces behind this trend. Frank also found that when bat declines were more severe — when more bats died, more caves were infected, or the decline was steeper — the rate of infant mortality was higher. A very good reason to protect nature Studies like this make addressing the ongoing collapse of bat populations ever more urgent. In North America, more than half of all bat species “are at risk of populations declining severely in the next 15 years,” according to a 2023 report by the North American Bat Conservation Alliance, a coalition of groups including government agencies and Bat Conservation International. This trend is mirrored globally.  WNS continues to spread west, invading new regions. Climate change is harming these animals, too. Bats’ flight-adapted physiologies make them highly susceptible to severe droughts and heat waves, as I previously reported. Plus, wind turbines — an important climate solution — are killing hundreds of thousands of bats each year in North America alone. Typically, the bats, most of which are migratory species, die from colliding with turbine blades, though it’s not clear why these animals are drawn to them. It’s not all bad news; there are ways to help bat colonies survive. Scientists have been testing a vaccine for WNS, for example. And research shows that slowing down wind turbines at night during certain times of year reduces collisions.  But these approaches can be costly — underscoring the value of studies that reveal, with more clarity, the payoff of investing in conservation, in both dollars and human lives. “At the end of the day, scientists and policymakers have to justify allocating resources” to things like fixing bridges and fixing schools, or to “fixing” bats, Manning said. “All of those have different returns associated with them.” “And if we don’t make an effort to show what the benefits are of ‘fixing’ the bats,” he said, “those benefits will be discounted.”
