(Beyond Pesticides, May 13, 2019) The Center for Biological Diversity (CBD) filed four lawsuits last week challenging the Trump administrationâs failure to release a trove of documents detailing how the administration is regulating dangerous pesticides, especially as they relate to endangered species. Meanwhile, the U.S. Environmental Protection Agency (EPA) released a set of proposed changes last week that would dramatically reduce protections for the nationâs most endangered plants and animals from pesticides known to harm them. The proposals ignore the real-world, science-based assessments of pesticidesâ harms, instead relying on arbitrary industry-created models. The EPA proposals would, for example, gut protections for endangered plants that are pollinated by butterflies and other insects by ignoring the fact that animals routinely move back and forth between agricultural areas and places where endangered species live. The proposals follow intensive efforts by Interior Secretary David Bernhardt to halt federal work on protecting wildlife from pesticides. They were released over a year after a draft biological opinion that was scuttled by the Trump administration found that the loss of pollinators from the insecticide chlorpyrifos would put hundreds of endangered species on a path to extinction. The so-called ârefinementsâ will make it easier for the EPA to claim that pesticides […]

(Beyond Pesticides, May 6, 2019) Beleaguered pollinators deal with a multitude of human-engineered threats: habitat fragmentation and loss via development and agricultural intensification, ecosystems and food sources tainted with toxic synthetic pesticides, and shrinking food sources via habitat and biodiversity loss. Research out of the Imperial College of London shows that such challenges are exacerbated, for bumblebees, by another impact of pesticide exposure â impaired flight endurance and dynamics. Published in the journal Ecology and Evolution in late April, âPesticide exposure affects flight dynamics and reduced flight endurance in bumblebeesâ examines how acute exposure to the neonicotinoid imidacloprid affects the nature of bumblebee foraging flight. The studyâs researchers find that worker bumblebees so exposed exhibit significant diminishment of flight endurance â measured as both distance and duration â to approximately one-third of what control workers demonstrate. This new information, aggregated with the many other factors that threaten pollinators, points to the importance of ending the use of chemical controls, such as the neonicotinoid imidacloprid, and transitioning to organic systems of agricultural pest management that do not rely on toxic compounds that harm wildlife, ecosystems, water resources, and humans. Previous research has shown numerous impacts of pesticide exposure on bumblebees, and of neonicotinoid exposure, in […]

(Beyond Pesticides, May 2, 2019) Researchers have documented an increase in food and drinking water residues of neonicotinoids, insecticides linked to breast cancer. Using the Pesticide Data Program (PDP), 1999-2015, of the U.S. Department of Agriculture, the researchers identified near-peak detection frequencies in 2015, after a decline from 2008-2013. Imidacloprid remains the most common neonicotinoid detected across imported commodities, while the neonicotinoids clothianidin, thiamethoxam, acetamiprid, and flonicamid are replacing imidacloprid in domestic production. Authors note that these newer neonicotinoids are potentially more toxic than imidacloprid, raising concerns for understudied human health and environmental impacts. The study, Trends in neonicotinoid pesticide residues in food and water in the United States, 1999â2015, published in the journal Environmental Health, finds the highest detection frequencies for neonicotinoids in drinking water, with 30% of treated drinking water turning out positive for imidacloprid in 2011. Certain fruits and vegetables are also frequently contaminated by neonicotinoids, with detection frequencies ranging from 20% to as high as 57% in the case of imidacloprid on cauliflower. While the study points to specific fruits and vegetables as posing higher risk, the main message reaches beyond individual commodity or individual neonicotinoid results. Authors uncover a systematic increase in detection of neonicotinoid […]

(Beyond Pesticides, May 1, 2019)Â Evidence of the dangers of glyphosate continues to mount: researchers at Washington State University have identified, in research that exposed pregnant rats to the compound, significant disease and pathology in subsequent generations. The rats were exposed, from day 8 through day 14 of gestation, to half the observable adverse effect level (NOAEL) of glyphosate. Although this study found negligible impacts on the pregnant rats themselves or on their first-generation offspring, dramatic increases in incidence of pathology showed up in the two subsequent generations, including reproductive (prostate and ovarian) and kidney diseases; obesity; and birth anomalies. The study, published in the journal Scientific Reports (an open access, multidisciplinary journal from Nature Research), and conducted by Michael Skinner, Ph.D. and five colleagues, is the first to assess the potential transgenerational impacts of glyphosate in mammals. Its results point to an emerging frontier in assessing the risks of glyphosate and other toxic chemicals, and add to the urgent and growing demand that the use of this particular toxic â and pervasive â pesticide be halted. The research team was interested in looking at possible transgenerational impacts of glyphosate in part because of its ubiquity: it is one of the […]

(Beyond Pesticides, April, 30, 2019) According to the latest blog post from pesticide industry propagandist Henry I Miller, the pollinator crisis either a) is not occurring; b) is not a problem; or, c) caused by varroa mites, pathogens, and habitat loss. Notwithstanding outlandish assertions that there is no pollinator crisis, new research is further undermining the long-held industry claim that it is mites and disease alone, and not pesticides that are harming pollinator populations. Published in the journal Scientific Reports by a team of Canadian scientists, this research finds that realistic exposure to neonicotinoid insecticides impairs honey bees ability to groom mites off of their bodies and increases infection with a disease known as deformed wing virus (DWV). “When bee colonies began to collapse years ago, it became clear there wasn’t just one factor involved, so we were interested in whether there was an interaction between two of the main stressors that affect bees: varroa mites and a neurotoxic insecticide, clothianidin,” said Nuria Morfin Ramirez, PhD, at the University of Guelph, Canada. Dr. Ramirez and her team exposed honey bees to a range of different concentrations (low, medium, high) of the neonicotinoid clothianidin, with some bees receiving combined stressors of […]

(Beyond Pesticides, April 22, 2019) This Earth Day, please join us in celebrating, propagating, and educating about a misunderstood and beneficial plant: clover. Clover: Provides your lawn with enough nitrogen to eliminate any need for ecologically hazardous synthetic fertilizers Acts as an important food source for declining pollinator populations Attracts earthworms and other beneficial soil microorganisms Remains green year-round Resists drought Helps your lawn resist disease A little history: “White clover used to be a standard ingredient in every grass seed mix; 75 years ago no one planted a lawn without mixing a little white clover in with the grass seed,â recounts Roger Swain, host of PBSâ The Victory Garden. After World War II, as the middle class grew and moved to suburban communities, chemicals developed during wartime found new uses on U.S. lawns. Chief among them was 2,4-D â an herbicide originally developed with the intent to wipe out potatoes in Germany and rice crops in Japan in a plan to starve the Axis powers into surrender. While 2,4-D was never used for that purpose, its ability to kill broadleaf plants while sparing grass species made it desirable on the farm for removing weeds around crops like wheat, corn, and […]

(Beyond Pesticides, April 19, 2019) Flying insects exposed to neonicotinoid insecticides or its breakdown products experience visual impairment and difficulty flying, according to a study published in the journal NeuroToxicology by researchers at the University of Saskatchewan, Canada. While at face value these impacts may sound non-lethal, any loss of fitness in the wild can make flying insects an easier meal for their predators. “Our findings suggest that very low doses of the pesticide or its metabolic products can profoundly and negatively affect motion detection systems that flying insects, such as locusts, grasshoppers and bees, need for survival,” said Jack Gray, PhD, an expert in neural control of animal behavior at the University of Saskatchewan. Researchers used locusts as proxies for other flying insects, as the visual processing in their brains is easy to track in laboratory settings. Moreover, as study co-author Rachel Parkinson notes, âBees and other flying insects use similar neural mechanisms to process visual motion,â making the implications of this study applicable to a wide range of other airborne insects. And rather than simply focus on the effects of exposure to a single active ingredient, researchers also studied whether its breakdown products (metabolites) resulted in similar impairment. […]

(Beyond Pesticides, April 12, 2019)Â The Center for Biological Diversity (CBD) announced on April 3 that it is suing the U.S. Fish and Wildlife Service (FWS) for its failure to release public records, despite multiple FOIA (Freedom of Information Act) requests, that would reveal on-the-ground impacts of FWS allowing use of neonicotinoids and genetically engineered (GE) crops in wildlife refuges. Last August, in yet another rollback of protections for wildlife, the environment, and public health, the Trump administration reversed a 2014 FWS decision to ban the use of neonicotinoids and GE crops in National Wildlife Refuges. If successful, the CBE lawsuit, filed in U.S. District Court for the District of Columbia, would compel the agency to provide the requested documents. This would allow the public, largely through the work of NGO (non-governmental organization) watchdogs, such as CBD and Beyond Pesticides, to understand what harms are being caused on the nationâs protected public lands by the administrationâs reversal of the 2014 ban. Hannah Connor, a CBD senior attorney, said, âThe goal of the lawsuit is to get them to comply with the Freedom of Information Act and produce the records that have been requested. . . . We arenât asking them to […]

(Beyond Pesticides, April 9, 2019) It is time for all local and state governments and school districts to stop the use of glyphosate/Roundup. The last month has seen a level of activity that supports immediate action. A second jury came in with the verdict that the herbicide caused plaintiffs’ non-Hodgkin’s lymphoma (NHL) âthis time handing the manufacturer, Monsanto/Bayer, a bill for $80 million ($5 million in compensatory damages and $75 million in punitive damages). Tell your Governor to act now to stop the use of glyphosate/Roundup.  Insurance companies are now backing away from Roundup. Harrell’s is a company that sells chemical pesticides, synthetic fertilizers, and âadjuvants and colorants,â among other products, primarily to golf courses, and to the horticulture-nursery, turf, and landscape sectors. The company announced on March 11 that it stopped selling products containing glyphosate as of March 1, 2019 because neither its current insurance company nor others the company consulted would underwrite coverage for the company for any glyphosate-related claims. Harrell’s CEO stated: âDuring our annual insurance renewal last month, we were surprised to learn that our insurance company was no longer willing to provide coverage for claims related to glyphosate due to the recent high-profile lawsuit and the many thousands of lawsuits since. We sought coverage […]

(Beyond Pesticides, April 4, 2019) Following on its verdict that the herbicide Roundup caused plaintiff Edwin Hardeman’s non-Hodgkin lymphoma (NHL), the jury on March 27 issued an award of $80 millionâ$5 million in compensatory damages and $75 million in punitive damagesâfor improper labeling and negligence on the part of the manufacturer and defendant, Monsanto. The trial, the first federal Roundup cancer trial, marks the first of a multidistrict litigation against Monsanto, with more than 1,600 similar lawsuits pending in San Franciscoâs federal court. The juryâs second verdict affirmed Mr. Hardemanâs allegations that Roundupâs design is defective and lacks sufficient warnings, and that Monsanto was negligent by not using reasonable care to warn about Roundupâs NHL risk. The Edwin Hardeman v. Monsanto Co. jury verdict marks the second multi-million dollar award to be granted in a landmark case against Bayer/Monsanto within the past year. Last August in San Francisco Superior Court, California groundskeeper Dewayne âLeeâ Johnson was awarded $39 million in compensatory damages, and $250 million in punitive damages in the first case that linked his NHL to Monsantoâs glyphosate/Roundup. In October, the judge in the case upheld the verdict, but reduced the award to $78 million. Mr. Hardeman is represented by […]

(Beyond Pesticides, March 28, 2019) A set of documents obtained by the Center for Biological Diversity reveals that the Trump administration has known for over a year â and actively concealed â that the organophosphate insecticide chlorpyrifos jeopardizes the existence of 1,399 endangered species. Top officials at the U.S. Department of the Interior, including Acting Secretary David Bernhardt, were privy to and prevented the release of a âbiological opinion,â completed by the Fish and Wildlife Service (FWS) in 2017, which contains a full analysis of the extensive environmental impacts wrought by three organophosphate insecticides. While chlorpyrifos is the worst of the three, the censored biological opinion includes similarly concerning findings for two other organophosphate pesticides, malathion and diazinon, which are currently jeopardizing 1,284 and 175 species, respectively. The U.S. Environmental Protection Agency (EPA) has determined that that all organophosphates have a common mechanisms of effect and therefore the multiple exposures to these pesticides lead to a cumulative risk. âIt’s outrageous that Trump, Bernhardt and the industry hacks inhabiting this administration are speeding the extinction of nearly 1,400 endangered species by refusing to take any action on chlorpyrifos,â said Lori Ann Burd, environmental health director at the Center for Biological Diversity […]

(Beyond Pesticides, March 25, 2019)Â EPA is using a regulatory loophole â the âtreated articles exemptionâ â to allow systemic insecticides to be used in mass quantities, without regulating or labeling them as required under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). EPA does not currently assess adverse effects on the environment and public health caused by widespread use of neonicotinoid insecticides delivered through seeds coated with the insecticides, resulting in widespread exposure to one of the most environmentally damaging classes of chemicals on the market. Tell your Congressional delegation that EPA must fully regulate treated seeds to protect the environment and public health. Pesticide-coated seeds are now ubiquitous, yet their far-reaching impacts on wildlife and human health continue to go unregulated. The introduction and spread of seed-delivered pesticides to major field crops, beginning around 2003, caused a massive increase in total neonicotinoid use nationwide. As of 2011, 34 to 44% of soybeans and 79 to 100% of maize acres were planted with coated seeds, accounting for an astounding 35-fold increase in nationwide neonicotinoid use from baseline rates prior to 2003 (Douglas and Tooker, 2015). Alarmingly, because the national pesticide survey conducted by the National Agricultural Statistics Service fails to […]

(Beyond Pesticides, March 22, 2019) A two-year study, published March 14, finds that field-relevant contamination with the neonicotinoid insecticide imidacloprid causes reduced body weight and metabolism in white-tailed deer, and â in fawns â mortality. Remarkably, researchers uncovered imidacloprid levels in free-ranging deer a full 3.5 times higher, on average, than the levels in the animals treated in their experiment. These new findings add to the mounting evidence of the hazards posed by current patterns of neonicotinoid use, while evidence of benefits remains sparse. The study, published in Nature Scientific Reports, includes two years of data on the physiological and behavioral outcomes of imidacloprid contamination in 80 white-tailed deer housed in a South Dakota State University captive research facility. Notably, researchers were unable to entirely control imidacloprid levels in untreated deer, most likely due to background contamination from corn- and soy-based feed, and surrounding vegetation infiltrated by runoff from nearby agricultural fields. This background contamination altered, but did not compromise, the analysis. Researchers found that imidacloprid levels detected in the spleens of treated and control animals were significantly predictive of reduced thyroid hormone levels, shorter jawbones, lower activity levels, and higher fawn mortality.

(Beyond Pesticides, March 21, 2019) Corporate food giant General Mills has thrown some weight behind regenerative agriculture, committing to converting one million acres of farmland to regenerative practices by 2030. Some – but not all – of the initiative involves organic land management. Regenerative agriculture is a term with a range of interpretations, but the key element is improving soil health through carbon sequestration. Robert Rodale, one of the early proponents of organic agriculture and a major publisher, coined the name to characterize a process that moves beyond sustainable maintenance and into improvement of resources. This methodology is gaining traction in the farming world because it is economically beneficial to farmers and promotes environmental remediation. A 2018 study shows that ecologically-based farming systems have fewer pests and generate higher profits than their conventional counterparts. âPractitioners who have done this the longest point to the fact that in extreme years, their farms will do better than those who do not,â says Jerry Lynch, General Millsâ chief sustainability officer, âAfter some transition time, depending on their location and cropping system, farmers are saving a lot of money because theyâre using fewer inputs.â In their press release, General Mills lays out three foci […]

(Beyond Pesticides, March 20, 2019) In a second verdict against Bayer/Monsanto yesterday, a jury found unanimously that a California manâs non Hodgkin lymphoma (NHL) was substantially caused by the herbicide glyphosate (Roundup). The case being heard in federal court in San Francisco now moves to the damages phase. Last August in San Francisco Superior Court, a California groundskeeper was awarded $39 million in compensatory damages, and $250 million in punitive damages in a case that linked his NHL to Monsantoâs glyphosate/Roundup. In October, the judge in the case upheld the verdict, but reduced the award to $78 million. According to the Associated Press, the trial judge, U.S. Judge Vince Chhabira âis overseeing hundreds of Roundup lawsuits and has deemed [this case] and two others âbellwether trials.â The case was brought by Edwin Hardeman of Santa Rosa, CA. He said he had been using Roundup since the 1980âs. During the trial, according to The Guardian, Judge Chhabria, âapproved Monsantoâs request to prohibit Hardemanâs attorneys from raising allegations about the corporationâs conduct, saying issues about its influence on science and government were a âsignificant ⌠distraction.ââ This set up a limitation that required the plaintiffâs attorneys to focus solely on studies linking the chemical to cancer […]

(Beyond Pesticides, March 19, 2019) Research is beginning to explain how systemic neonicotinoid insecticides affect often overlooked species of ground nesting bees. While much of the current scientific literature has focused on the impacts of pesticides to bumblebees and honey bees, a study, Chronic contact with realistic soil concentrations of imidacloprid affects the mass, immature development speed, and adult longevity of solitary bees, recently published in Scientific Reports, confirms that wild, soil-dwelling bees are at similar risk. As policy makers consider ways to protect pollinators, this research finds that uncontaminated soil is an important aspect of ensuring the health of wild, native bees. âThis is an important piece of work because itâs one of the first studies to look at realistic concentrations of pesticides that you would find in the soil as a route of exposure for bees,â said Nick Anderson, co-author of the study. âItâs a very under-explored route, especially for some of the more solitary species that nest in the ground.â In order to study the impact of neonicotinoids on ground nesting bees, researchers used orchard mason bees and leafcutter bees as proxies, as they are easier to gather and rear in the lab, and have a similar ecology […]

(Beyond Pesticides, March 15, 2019)Â Beyond Pesticides and others have worked for many years to educate stakeholders and policy makers about the dangers of pesticides, and to transform pest management by eliminating a reliance on toxic pesticides and advancing organic management practices. Considerable focus has been on glyphosate, which is used in several herbicides, most notably in Bayerâs (then Monsantoâs, until its 2018 purchase by Bayer) Roundup. The compound has had a relatively high profile in the pesticide landscape, due in part to the ubiquity of its use, and in part to the tireless work of health and environmental advocates and scientists to expose its risks. With that profile, glyphosate has been a bit of a stand-in for the dangers of pesticides broadly. As journalist Carey Gillam said at Beyond Pesticidesâ 36th National Pesticide Forum in 2018, âGlyphosate is the poster child for the bigger pesticide problem. . . . If it goes away tomorrow, we are [still] not okay.â The variety of risks this compound poses is broad, and pushback and risk evidence on its use come from multiple sides. This Daily News Blog focuses on recent developments on several of those fronts, all of which advanced knowledge and momentum, […]

(Beyond Pesticides, March 13, 2019) A study on the impact of two neonicotinoid pesticides shows differential gene expression in bumblebees (Bombus terrestris) after exposure. Considering the current worldwide plight of insects, the authors of point to the cutting edge research as both a reason and a methodology to more carefully examine the effects of pesticides. âCaste- and pesticide-specific effects of neonicotinoid pesticide exposure on gene expression in bumblebeesâ was published in the journal Molecular Ecology in early March. Researchers fed variable colonies with clothianidin or imidacloprid-laced sucrose. They analyzed gene expression in the heads of worker bumblebees and colony queens using RNA sequencing (RNA-seq), inspired by biomedical techniques. This approach allowed for new insight on what genes and pathways are affected by neonicotinoid exposure. Study author Yannick Wurm, PhD, stated in a press release, âOur work demonstrates that the type of high-resolution molecular approach that has changed the way human diseases are researched and diagnosed, can also be applied to beneficial pollinators. This approach provides an unprecedented view of how bees are being affected by pesticides and works at large scale. It can fundamentally improve how we evaluate the toxicity of chemicals we put into nature.â Clothianidin had a stronger […]

(Beyond Pesticides, March 12, 2019) Fifty years after the end of the Vietnam War, the Agent Orange byproduct dioxin continues to contaminate Vietnamâs soils and wildlife, and subsequently affect human health. In their review, scientists at Iowa State and the University of Illinois focus on the locations where hot spots and contaminated sediments have persisted after 130,000 fifty-five gallons drums of toxic herbicides were sprayed over Vietnamâs farm fields and jungle canopies during the war. “Existing Agent Orange and dioxin research is primarily medical in nature, focusing on the details of human exposure primarily through skin contact and long-term health effects on U.S. soldiers,” says Ken Olson, PhD, co-author on the article. “In this paper, we examine the short and long-term environmental effects on the Vietnamese natural resource base and how persistence of dioxin continues to affect soils, water, sediment, fish, aquatic species, the food supply, and Vietnamese health.” While public attention has generally focused on the ârainbow herbicides,â such as Agent Orange, used during the Vietnam war, it is the dioxin TCDD (2,3,7,8 tetrachlorodibenzodioxin), a byproduct of Agent Orangeâs manufacturing process, that has caused the most lasting damage within the country. While the breakdown period for Agent Orange herbicides 2,4-D […]

(Beyond Pesticides, March 8, 2019) Researchers from the U.S. and Switzerland have published their findings, a beginning assessment of how use of a new category of pesticides â dsRNA (double stranded RNA), which is less a traditional pesticide than a genetically based pesticide âtechnologyâ â might impact soils and non-target microorganisms in the soil. The co-authors (Kimberly M. Parker, PhD, et al.) note that, âThe ecological risk assessment of these emerging pesticides necessitates an understanding of the fate of dsRNA molecules in receiving environments, among which agricultural soils are most important.â Their research appeared in late January 2019 in Environmental Science & Technology. Previously, technical hurdles in measuring dsRNA had stymied scientistsâ ability to quantify the genetic material and its degradation products in soil, but these investigators were able to attach a radioactive atom to the molecule, âtaggingâ it so it could be followed through a series of simulated soil systems representative of those in the ârealâ world. Researchers were able to measure the presence of the material at concentrations as low as a few nanograms of dsRNA per gram of soil. The work of these researchers represents the beginning of understanding the ecological risks of these emerging dsRNA pesticides. They demonstrated […]

(Beyond Pesticides, March 7, 2019) A publication in the journal Environmental Health Perspectives highlights findings from a recent study showing that environmental concentrations of the neonicotinoid insecticides thiacloprid and imidacloprid increase expression of a gene linked to hormone-dependent breast cancer. Authors of the featured study uncovered a pathway through which neonicotinoids stimulate excess estrogen production, known to occur during the development of progressive hormone-dependent breast cancer. In the words of the authors, âOur findings highlight the need for further research to assess the potential impacts of low-dose and chronic exposure to neonicotinoids on endocrine processes affecting womenâs health.â The study, published in Environmental Health Perspectives in April 2018 by researchers at the University of Quebec, is not the first to point to a potential link between neonicotinoid exposure and breast cancer. A 2015 study by the same research group revealed that the neonicotinoids thiacloprid and thiamethoxam, along with the herbicide atrazine, induce similar effects in breast cancer cells. In both studies, exposure to neonicotinoids alter promoter activity to induce heightened production of the enzyme aromatase, which is known to stimulate estrogen production and thereby cancer cell proliferation. The recently published study, authored by Silke Schmidt, PhD, brings greater urgency to […]

(Beyond Pesticides, March 5, 2019) Wild, edible plants subject to drift from the herbicide glyphosate during forestry operations can be contaminated with the chemical an entire year after an initial application, according to a new study published in the Canadian Journal of Forest Research. Glyphosate is often used in forestry to knock down unwanted trees, shrubs, and other plants after clear-cutting to provide room for the regrowth of trees deemed valuable. However, this new research shows that ânon-targetâ species, such as raspberries and blueberries, eaten by wildlife and sometimes wild foraged by humans can retain significant levels of glyphosate contamination due to drift and overspray. Forester Lisa Wood, PhD, from the University of Northern British Columbia began this research based on input and requests from Canadian indigenous First Nations communities. Back in 2013, shrubs foraged by traditional berry-pickers in northeastern British Columbia were sampled and found to contain glyphosate residues, leading to the need for a broader investigation. Dr. Wood sampled the roots and shoots of 10 plant species from an area that had been aerially sprayed with glyphosate a year prior as part of forestry operations to clear aspen and make room for coniferous re-plantings. The 10 plants, which […]

(Beyond Pesticides, March 4, 2019) Last week, U.S. Representative Earl Blumenauer (D-OR) reintroduced the Saving Americaâs Pollinators Act (H.R.1337) to cancel specific bee-toxic pesticides and establish a review and cancellation process for all pesticides that are potentially harmful to pollinators. The specific pesticides targeted in the bill include the systemic insecticides imidacloprid, clothianidin, thiamethoxam, dinotefuran, acetamiprid, sulfoxaflor, flupyradifurone, and fipronil. The bill also establishes requirements for review of other potentially bee-toxic chemicals by an independent pollinator protection board, and requires annual reports on the health and population status of pollinators. The bill creates a sustainable model for pollinator protection in the face of ongoing obstruction by an increasingly industry-influenced EPA. There are 29 cosponsors to date. The current bill is the fifth version of Saving America’s Pollinators Act (SAPA), which was first introduced by U.S. Representative Conyers (D-MI) in 2013. The newest version differs from previous bills in its bold definition of who should have responsibility for assessing harm to pollinators. SAPA 2019 calls for the establishment of a Pollinator Protection Board, to be composed of expert scientists, beekeepers, farmers, members of environmental organizations and other key stakeholders, nearly all of whom must not have any conflict of interest or affiliation […]
