Findings Show Endocrine-Disrupting Glyphosate Weed Killer Threatens Women’s Reproductive Health

Thursday, April 17th, 2025

(Beyond Pesticides, April 17, 2025) A literature review in Reproductive Sciences finds glyphosate (GLY) and glyphosate-based herbicides (GBH) impact women’s reproductive health, adding to the long list of documented harm from this widely used weed killer. The authors note, “Considering the widespread use of GLY, the controversy regarding its endocrine-disrupting potential and reproductive toxicity, and the innumerable lawsuits filed against Bayer and Monsanto by consumers for morbidities related to Roundup™ exposure, the purpose of this review is to summarize the current literature on the potential adverse effects of GLY and GBHs on the female reproductive tract and discuss possible clinical implications on reproductive health outcomes, including polycystic ovarian syndrome (PCOS), endometriosis, and female fertility.”  Glyphosate and aminomethylphosphonic acid (AMPA), the primary metabolite (breakdown product) of GLY, are found throughout the environment in soil and water, as well as in samples of blood, urine, seminal plasma, and breast milk. Studies have detected residues in farmworkers, as well as “in the urine of 60–80% of the general public in the USA, including pregnant women and children.” (See studies here, here, and here.) The ubiquitous use of GLY and GBH, and subsequent persistence, threatens the health and well-being of all.  Previous studies have […]

Indiscriminate Poisoning of Neonicotinoid Insecticides Contributes to Insect Apocalypse, Study Finds

Tuesday, April 15th, 2025

(Beyond Pesticides, April 15, 2025) A study in Communications Earth & Environment, through field, greenhouse, and laboratory experiments involving three plant bug species, finds both species-specific and sex-specific sensitivity responses to neonicotinoid insecticide exposure—highlighting the threats to grassland insect communities that are disregarded in risk assessments. By assessing the effects of MospilanÂŽSG, with the active ingredient acetamiprid, the researchers determine that nontarget plant bug species are highly sensitive to neonicotinoids and face community-level harm with exposure. As systemic insecticides, neonicotinoids move through the vascular system of plants, expressing the poison through pollen, nectar, and guttation droplets. As persistent pesticides, these chemicals indiscriminately poison insects and organisms in the soil. “Although pesticides have been proposed as one of the main causes of insect decline, there are still few studies assessing their effects on non-target species under field conditions,” the authors state. They continue: “In this study, we address the existing research gap on insecticide exposure of non-target herbivorous insects, focusing on two main aspects: (1) realistic exposure scenarios, (2) community-level effects, i.e., differential sensitivity between closely related species and between sexes of the same species. We chose plant bugs (Heteroptera: Miridae) as a model group because they are one of the […]

Literature Review of Over 200 Studies Highlights Pesticide Threats to Women’s Reproductive Health

Tuesday, April 8th, 2025

(Beyond Pesticides, April 8, 2025) A comprehensive literature review in Environment & Health analyzes evidence from human biomonitoring, epidemiological studies, and toxicological studies that link adverse effects on women’s reproductive health, specifically impacting the ovary, to pesticide exposure. In examining the scientific literature, consisting of over 200 studies performed in the last 25 years, the authors find pesticide exposure threatens women’s health through ovarian dysfunction. “Epidemiological studies have shown that pesticide exposures are associated with early/delayed menarche [first occurrence of menstruation], menstrual cycle disorders, early menopause, long time to pregnancy, polycystic ovary syndrome, primary ovarian insufficiency, infertility, and implantation failure in women,” the researchers state. They continue, “Both in vivo [in animals] and in vitro [in cells] studies have shown that exposure to pesticides disrupts the estrous cycle, reduces the follicle pool, alters hormone levels, and impairs oocyte [egg] maturation.” These reproductive implications are noted with many different classes of pesticides, such as insecticides, including organochlorine pesticides (OCPs), organophosphates (OPs), pyrethroids, and neonicotinoids, as well as herbicides and fungicides. The authors, however, comment on present research gaps: “Much of the available epidemiological evidence focuses on legacy insecticides, such as OCPs, and a subset of insecticides that are still in use […]

Sampling Finds Pesticides Throughout Environment with Toxic Mixtures from Agricultural Use

Friday, March 28th, 2025

(Beyond Pesticides, March 28, 2025) The Rhine Valley in southwestern Germany is renowned for the agricultural bounty it has provided for centuries. Today, the area is home to dense wine, vegetable, fruit, and cereal cultivation. However, a study shows that current regulation of pesticides, even in the relatively progressive European Union, is inadequate to protect humans and all the other organisms that produce the environment necessary for human life and civilization.  The study goal was to determine how far—and which—pesticides traveled beyond the croplands of vegetables, fruit orchards, and cereals, as well forested lands, into nontarget areas that should serve as refugia for plants, animals, and invertebrates not considered pests. Based at the Landau Institute for Environmental Sciences at the University of Kaiserslautern-Landau, the researchers used innovative methods to measure the types, concentrations, and distribution of pesticides. They took samples from three landscape categories—vegetation, topsoil, and surface water—at 78 sites distributed along six transects, each reaching from the valley floor to the tops of the mountains on either side. Samples were taken from grasses, shrub leaves, and topsoils along each transect, together with water samples from rivers, small streams, ponds, and puddles. They tested for 93 current-use pesticides (CUPs). There […]

Flying Through States, Industry Seeks To Stop Lawsuits Over Failure to Warn of Pesticide Dangers

Wednesday, March 26th, 2025

(Beyond Pesticides, March 26, 2025) State legislation to quash lawsuits against chemical manufacturers because of their “failure to warn” about the hazards of their pesticide products is moving forward in seven state legislatures (Iowa, Missouri, Idaho, Florida, North Dakota, Tennessee, and Oklahoma) across the United States. After three bills failed to pass (Mississippi, Wyoming, and Montana) and one bill is awaiting signature into law by the Governor’s Office (Georgia), Beyond Pesticides, working with a broad coalition, is pushing back. (See Beyond Pesticides’ Failure to Warn resource hub, background materials, and opportunities for action.) If adopted, the “immunity from litigation” legislation would set a dangerous precedent for state common law claims against any manufacturers of products with toxic ingredients. Currently, pesticide labels under federal and state law generally do not warn of potential chronic effects, such as cancer, reproductive effects, infertility, birth defects, Alzheimer’s and Parkinson’s disease, diabetes, cardiovascular damage, and more (see Pesticide-Induced Diseases Database), but warn of acute effects, such as rashes, headaches, stinging eyes, and more. After years of large jury awards, preemptive settlements, and lost appeals in cases involving exposure to the weedkiller glyphosate, Bayer/Monsanto is trying to stop the company’s financial hemorrhaging with a state-by-state strategy […]

Children Exposed to Pesticides Experience “Cellular Distress” and Chronic/Acute Diseases, Study Finds

Friday, February 28th, 2025

(Beyond Pesticides, February 28, 2025) It is well established that children are more vulnerable than adults to environmental insults such as pesticides, from conception onward. Children living in agricultural areas are exposed differently from those in urban areas. A study of rural children by researchers at Mexico’s Universidad AtĂłnoma de Nayarit compared two communities located less than a quarter of a mile from agricultural fields with one control community located more than a mile away. The study shows that children in the field-adjacent towns are clearly exposed to pesticides and are experiencing cellular distress as a result. The state of Nayarit is on the west coast of Mexico near Mazatlan. Rural children encounter aerial application, spray drift, and erosion. If their parents are agricultural workers and especially if they apply pesticides, they bring home residues on their clothes. Residential storage of pesticides and small children’s propensity to play in the dirt and put things in their mouths exacerbate their exposure. Urban children get hit by pesticides in their homes, schools, and parks. The researchers took blood and urine samples from 431 children aged six to 12 and collected questionnaires as to pesticide exposures from the parents or guardians. They assayed the […]

Microplastics Interact with Pesticides, Exacerbating Environmental Health Threats, Studies Find

Tuesday, February 25th, 2025

(Beyond Pesticides, February 25, 2025) A literature review of over 90 scientific articles in Agriculture documents microplastics’ (MPs) increase in the bioavailability, persistence, and toxicity of pesticides used in agriculture. The interactions between MPs and pesticides enhance the threat of pesticide exposure to nontarget organisms, perpetuates the cycle of toxic chemical use, and decreases soil health that is vital for productivity. “The increasing presence of MPs in agricultural ecosystems has raised concerns about their impact on pesticide bioavailability, efficacy, and environmental behavior,” says study author Kuok Ho Daniel Tang, PhD, a global professor in the Department of Environmental Science at the University of Arizona. He continues, “These synthetic particles interact with pesticides through adsorption and desorption processes, altering their distribution, persistence, toxicity, and uptake by plants and other organisms.” Microplastics in the Environment As Beyond Pesticides has previously reported, microplastics are ubiquitous and threaten not only human health but all wildlife in both aquatic and terrestrial ecosystems. The universal distribution of plastics means that they cannot be avoided. Humans and other organisms take up plastics in the form of microparticles and nanoparticles by inhalation, ingestion, and skin contact every day. Microplastics are about the width of a human hair; nanoplastics […]

Trump Administration’s Dismantling of Federal Environmental and Public Health Programs Shifts Focus to States

Monday, February 24th, 2025

(Beyond Pesticides, February 24, 2025) The sweeping firing of federal workers, including an estimated 200,000 probationary employees (under one to two years of employment), will have a broad impact on programs to protect health and safety as well as the environment, leaving a critical need for local and state government to fill some of the gaps in critical programs, where possible. A headline in Science magazine warns, “Mass firings decimate U.S. science agencies,” and the dean of the College of Agricultural Sciences at Oregon State University told Oregon Public Broadcasting, “We’ve lost half of our teams, and all of these up-and-coming young scientists. . .so it’s like we’ve lost the next generation of scientists in agriculture and natural resources.” The same applies to important positions across the federal government, affecting every aspect of work necessary to protect public health and biodiversity and address the climate crisis. In response to President Trump’s executive orders and actions, there has been, as The New York Times reports, “new lawsuits and fresh rulings emerging day and night,” raising what experts fear may become a constitutional crisis. With the upheaval in the federal government, attention turns to the importance of state and local policies and […]

Exposure to Glyphosate Herbicide Adversely Affects Perinatal Health, Study Finds

Thursday, February 20th, 2025

(Beyond Pesticides, February 20, 2025) Researchers at the University of Oregon found that the rollout of genetically engineered corn in the early 2000s, followed by exponential increases in glyphosate-based herbicides, “caused previously undocumented and unequal health costs for rural U.S. communities over the last 20 years.” Their results “suggest the introduction of GM [genetically modified] seeds and glyphosate significantly reduced average birthweight and gestational length.” The conclusions of this study emerge as fossil fuel advocates, including President Donald Trump, are mobilizing to pioneer “energy dominance” despite the market movement toward renewable energy. Just as chemical-intensive farmers and land managers continue to spray synthetic fertilizers and pesticides, a successful rollout of alternatives must rely on feeding the soil rather than the plant. Advocates continue to demand that elected officials and regulators embody the precautionary principle and scientific integrity in decision-making. Given the hostile federal climate on anything relating to holistic solutions, communities are coming together to move beyond input-dependent land management systems and adopt organic criteria of allowed and prohibited substances, mandatory public comment process, independent third-party certification, and a federal advisory board (National Organic Standards Board) consisting of farmers, environmentalists, consumers, scientists, economists, researchers, and other stakeholders, with binding recommendations […]

Neonic Insecticide Impairs/Kills Beetle Listed as Threatened and Important to Ecosystem Health, But Not Protected

Wednesday, February 5th, 2025

(Beyond Pesticides, February 5, 2025) A study in PLOS One finds acute and chronic impacts of nontarget toxicity on the American burying beetle, Nicrophorus americanus, with neonicotinoid insecticide exposure. In assessing environmentally relevant concentrations of the neonicotinoid insecticide imidacloprid with N. americanus, the researchers note both mortality and behavioral effects that leave the species at high risk of predation. These effects mean the American burying beetle “may be at greater risk to insecticide exposure than previously thought and vulnerable to episodic, low-dose neonicotinoid exposure,” the authors say. This data sheds important light on a species that has been listed by the U.S. Fish and Wildlife Service (USFWS) as threatened. Burying beetles provide important ecosystem services within the environment such as “burying carrion, increasing available nutrients in soil, and expediting carrion decomposition, while acting as a food source for secondary consumers,” the researchers state. (See more on ecosystem services and beneficial insects here, here, and here.) The N. americanus species are habitat generalists and can be found in grasslands, wet meadows, and forested areas that neighbor agricultural lands and introduce the beetles to pesticide drift and soil residues. While acute and chronic effects vary in duration and severity, pesticide exposure resulting […]

Study Demonstrates Health Benefits of Organic Diet Over That Consumed with Toxic Pesticides

Tuesday, February 4th, 2025

(Beyond Pesticides, February 4, 2025) Adopting a fully organic diet can reduce pesticide levels in urine within just two weeks “by an average of 98.6%” and facilitate faster DNA damage repair relative to a diet of food grown with chemical-intensive practices, according to findings from a randomized clinical trial published in Nutrire. The authors explain that their finding “is likely due to two main factors: the presence of compounds characteristic of [an organic] diet, which may have high levels of antioxidants that can protect DNA and also induce DNA repair [], and the absence or decrease in the incidence of pesticides in this type of diet, which are recognized for their genotoxic effects and have the ability to affect the genetic repair system of organisms [].” Public health professionals and affected families continue to sound the alarm on the unprecedented rates of chronic illnesses, many linked to pesticide exposure, as well as the urgency in developing solutions that acknowledge the connection to policies governing agriculture, nutrition policies, and public health. Background and Methodology The purpose of this study is to identify any relationships in health effects of chemical-intensive versus organic diets in a two week-period. More specifically, the authors say […]

Study Finds Pesticide Exposure to Bees During Dormancy or Overwintering Disruptive of Reproductive Health

Thursday, January 30th, 2025

(Beyond Pesticides, January 30, 2025) A research article in Biology Letters, published by The Royal Society, finds that the neonicotinoid insecticide imidacloprid disrupts survival and reproductive patterns in Bombus impatiens bumblebees. The study adds to the wide body of science highlighting how exposure to pesticides “can result in immediate mortality or cause long-term detrimental effects on pollinators‘ health, lifespan and reproductive success,” the authors state. The researchers performed two experiments to assess the effects of various concentrations of imidacloprid, one of which focuses on bees during diapause, a period of dormancy. “Wild bees, which provide the majority of pollination services worldwide, undergo an annual life cycle that includes a winter diapause, that can span over 75% of their life cycle and during which their metabolism, growth and development are halted,” the authors note. They continue: “The time spent in diapause can have lasting effects on pollinator fitness and their ability to establish nests or colonies in the following spring. This period is especially critical for social bee colonies, which are founded by a single queen after diapause and play a vital role in large-scale pollination.” Exposure to pesticides during diapause can occur while bee species overwinter in contaminated soils.

Action Today: U.S. Fish and Wildlife Service Proposes Critical Habitat for Endangered Rusty Patched Bumble Bee

Monday, January 27th, 2025

(Beyond Pesticides, January 27, 2025) A public comment period ends today, January 27, 2025, on the U.S. Fish and Wildlife Service’s (FWS) proposed critical habitat rule to protect the rusty patched bumble bee under the Endangered Species Act (ESA). This proposal is responsive to the agency’s 2024 stipulated settlement agreement resulting from years of advocacy and government review and a 2023 court order (NRDC et al. v. U.S. Fish and Wildlife Service, et al.). The proposal follows a 2017 determination by the agency that lists the bumble bee as an endangered species. (See previous Daily News here, here, here, here, and here.) >> Tell the U.S. Fish and Wildlife Service to fully protect the endangered rusty patched bumble bee by finalizing its proposed critical habitat rule with strengthening provisions. The FWS proposal grows out of a species status assessment (SSA) conducted by “15 scientists with expertise in bumble bee biology, habitat management, and stressors (factors negatively affecting the species).” University of Illinois Urbana-Champaign insect ecologist Jason Robinson, PhD concludes in his paper, “Project-specific bumble bee habitat quality assessment,” “As the first social insect listed under the ESA, the listing of RPBB has required new methods for biological assessment. This species has a complex life cycle requiring a mosaic of different habitat types, […]

Waterway Contamination Findings with Neonicotinoid Insecticide a Threat to Aquatic Ecosystems and Biodiversity

Friday, January 24th, 2025

(Beyond Pesticides, January 24, 2025) Based on data collected from government sources and independent monitoring, a multidisciplinary team of researchers at the University of Connecticut finds that 46% of Connecticut waterway samples are contaminated with levels of the neonicotinoid insecticide, imidacloprid—one of the most widely used insecticides in the United States on lawn and golf courses. The authors relied on federal data from U.S. Environmental Protection Agency (EPA) and U.S. Geological Survey (USGS), state-level data from Connecticut Department of Energy and Environmental Protection (CT-DEEP), and a small-scale data collection study by the Clean Rivers Project funded by the nonprofit Pollinator Pathway, Inc. In their report, Neonicotinoids in Connecticut Waters: Surface Water, Groundwater, and Threats to Aquatic Ecosystems, the researchers provide the most comprehensive view to date of neonicotinoid levels in Connecticut and offer critical recommendations for future testing within the state and nationally, given glaring data gaps. It is important to note that the authors acknowledged early in the report the “abandonment” of Integrated Pest Management in “the use of neonicotinoids has coincided with and been implicated in the decline of many non-target species of insects, in particular pollinators such as bees () and monarch butterflies.” They point out that […]

Lit Review Shows Depth of Research Linking Pesticide-Induced Effects on Immune System, Leading to Disease Outcomes

Wednesday, January 15th, 2025

(Beyond Pesticides, January 15, 2025) There is robust scientific literature that unpacks the adverse human health effects of pesticide exposure, however immunological impacts do not receive adequate attention in regulatory review processes, according to an in-depth literature review. In a piece published in Frontiers in Immunology (2024) critiquing recent peer-reviewed scientific studies, as well as unpublished research produced by the Institute of Biology and Experimental Medicine in partnership with the National Scientific and Technical Research Council in Argentina, researchers assess immune system effects of pesticide exposure, which creates the conditions for deadly health conditions including various forms of cancer. The focus of this study, according to the authors, is “to critically review fundamental aspects of toxicological studies conducted on PPPs [Plant Protection Products] to provide a clearer understanding of the risks associated with exposure to these compounds on human health.” PPPs are pesticide products that contain more than one active ingredient, and can include synergistic ingredients that supercharge them alongside inert ingredients that pesticide companies are not legally required to disclose under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), but are often manipulated biologically and chemically active. Most studies analyze the toxicological impacts of active ingredients in isolation rather […]

Investigative Report Finds Canada’s Reversal of Neonicotinoid Ban Influenced by Bayer/Monsanto

Wednesday, December 18th, 2024

(Beyond Pesticides, December 18, 2024) A bombshell investigation conducted by Canada’s National Observer finds that Bayer, which acquired the Monsanto chemical company in 2018, colluded with environmental and public health regulators in Canada to obstruct a proposed neonicotinoid insecticide ban originally introduced in 2018. Advocates were stunned back in 2021 when Canada’s Pest Management Regulatory Agency (PMRA)—the Canadian counterpart to the U.S. Environmental Protection Agency (EPA)—reversed its decision to phase out imidacloprid, clothianidin, and thiamethoxam by 2023. The weaponization of scientific institutions and regulatory processes is commonplace in the U.S. context, with U.S. Right to Know publishing a report earlier this year on the corrupting impact of pesticide manufacturers at the Entomological Society of America 2023 annual meeting. (See Daily News here.) There are numerous Office of Inspector General (OIG) reports signaling EPA corruption and failures, including persisting industry influence in the cancer risk assessment process, inadequate leadership in addressing community harms of a former creosote-treated wood preservative plant turned Superfund site in Pensacola, Florida, and failure to protect the public from endocrine-disrupting chemicals, to name several examples. In a recent press release, the David Suzuki Foundation, alongside numerous medical, legal, and civil society organizations, is calling on Health Canada […]

Study Links Numerous Chemical Families of Pesticides to Endocrine Disrupting Effects, Including Obesity

Tuesday, December 17th, 2024

(Beyond Pesticides, December 17, 2024) A systematic review of studies on pesticides as endocrine-disrupting chemicals (EDCs) on body weight, published in Biomedicines, evaluates 36 clinical and preclinical studies and links their agricultural use to obesity. The authors, with the lead researchers from the School of Medicine and Health Sciences at Catholic University of Valencia San Vincente, Valencia, Spain, assess studies on a range of pesticides, including organophosphates, pyrethroids, neonicotinoids, and others. In addition to concluding that the EDCs promote obesity, they report that the chemicals cause “other anthropometric changes by altering lipid and glucose metabolism, modifying genes, or altering hormone levels such as leptin.” Endocrine disruption and obesity are public health concerns, and there is a wide body of science linking pesticide exposure to these effects (see more here). “Obesity is considered to be a worldwide pandemic that leads to an increase in medical costs and thus becomes a public health problem,” the researchers share. They continue, “[Obesity] is also associated with the increased production of environmental chemicals, also called environmental obesogens, used mainly in agriculture, as disease vector control, helping to prevent harmful effects caused by fungi, bacteria, or even pests, using pesticides, insecticides, and herbicides, or endocrine disruptors […]

Review Cites Memory and Learning Impairments; Children, Workers, and Nontarget Organisms at Risk

Thursday, December 12th, 2024

(Beyond Pesticides, December 12, 2024) A literature review of 161 articles in Discover Toxicology finds that pesticides with different mechanisms of action cause memory and learning impairments. These effects are noted in nontarget species including humans. Pesticide “[e]xposure during development, as well as chronic environmental and occupational exposure, can contribute to decreased cognitive performance,” the researchers say. With a focus on organophosphate pesticides, synthetic pyrethroids, and neonicotinoid insecticides, the authors highlight neurological impacts. Both learning and memory are crucial for the survival of many species. “Considering the importance of learning and memory for human and non-human animal behavior and the growing association between pesticide exposure and cognitive impairment, the aim of this review was to describe the studies showing the impact of pesticide exposure on memory and learning abilities in nontarget species, providing evidence of the impact of pesticides in central nervous system function,” the researchers state. The 161 articles included in the review were identified through database searches in PubMed/Medline and Scielo. The authors note, “Inclusion criteria for article selection included all articles published in English between 2015 and 2024 containing original studies in animals or humans with single or multiple pesticides exposure.” The articles consist of 132 preclinical […]

Widely Used Insecticide Imidacloprid Negatively Impacts Soil Communities, Study Finds

Tuesday, December 10th, 2024

(Beyond Pesticides, December 10, 2024) Scientists from the Engineering Research Center of Protection and Utilization of Plant Resources at Shenyang Agricultural University in China reveal adverse effects of imidacloprid on soil communities in a study published in Pesticide Biochemistry and Physiology. The researchers highlight risks to nematodes from imidacloprid exposure in maize soil, as well as potential resistance mechanisms that impact not only nematode populations but also overall soil health. Maize, or corn, a productive crop grown worldwide, is a source of food and biofuel. In assessing the soil and species in maize fields after exposure to imidacloprid at various concentrations, the study researchers assess the impact of neonicotinoid insecticides on nontarget organisms and the health of soil communities. The assessment includes an evaluation of nematodes’ survival, growth, reproduction, and chemotaxis/locomotion behavior. With a statistical analysis of lipid and lipofuscin accumulation, acetylcholinesterase (an enzyme necessary for neurotransmission) activity, and gene expression levels, the study results show that imidacloprid induces: significantly reduced abundance and diversity of nematode species. negative effects on body length, reproduction, locomotion, lipid accumulation, lipofuscin accumulation, and acetylcholinesterase activity in Caenorhabditis elegans ( elegans). the upregulation of gpa-1, cyp-35a2, fat-2, fat-6, hsp-16.41, and hsp-16.2, along with the downregulation […]

Studies Cite Risk Assessment and Regulatory Deficiencies in Protecting Ground-Nesting Bees

Tuesday, December 3rd, 2024

(Beyond Pesticides, December 3, 2024) In an article in Science, Sabrina Rondeau, PhD reviews her research from 2022-2024 showcasing species of ground-nesting bees, often found in crop fields, that are highly vulnerable to soil pesticide residues and subsequently suffer population declines. Dr. Rondeau, a postdoctoral fellow in the Department of Biology at the University of Ottawa, points to regulatory deficiencies, specifically in environmental risk assessments (ERAs), and the detrimental effects of pesticides on pollinators that threaten food security and biodiversity. “Modern intensive agriculture faces a critical paradox: The very pesticides designed to protect our crops endanger essential pollinators that sustain their productivity,” Dr. Rondeau says in the article. Her research (see here, here, here, here, here, and here) identifies important gaps overlooked in current assessments and regulations for bee species, including the common eastern bumble bee (Bombus impatiens) and the hoary squash bee (Xenoglossa pruinosa). Bumble bee queens in temperate climates hibernate for 6-9 months in the soil, while the hoary squash bee is a solitary ground-nesting species. Reference additional Daily News coverage on ground-nesting bees here and here. “‘Our findings show that over 70% of wild bee species, which are crucial for pollinating our food crops, face significant risks […]

Amid the Health, Biodiversity, and Climate Crises, Nominee to EPA Head Walks in Lockstep with Trump Denialism

Monday, November 18th, 2024

(Beyond Pesticides, November 18, 2024) With the reported appointment of former U.S. Representative Lee Zeldin (R-NY) to the position of Administrator of the U.S. Environmental Protection Agency (EPA), Senate confirmation hearings will be an important process that is intended to shine a light on individual nominations, the policies of an administration, and the science (or lack thereof) behind them. There have been reports in the media that the Trump administration may attempt to circumvent the “advice and consent” rule of the U.S. Senate by making recess appointments. Alexander Hamilton wrote in the Federalist Papers: No. 76 that Senate confirmation hearings act as a safeguard against the appointment of “unfit” officials. Numerous interviews and critiques are painting a picture of what the future holds for environmental protection and all that means for addressing the serious catastrophic threats of ongoing and escalating health, biodiversity, and climate crises. “Mr. Trump, who has called climate change a “hoax,” has targeted “every one” of Mr. Biden’s policies designed to transition the United States away from fossil fuels,” according to The New York Times reporting on June 26, 2024.

(Beyond Pesticides, November 15, 2024) There are many pie-in-the-sky ideas to address the climate crisis while allowing business as usual in the extractive and industrial systems that are causing the crisis. Prominent among them are geoengineering to block sunlight and building industrial plants to prevent carbon dioxide (CO2) from reaching the atmosphere, known as carbon capture and sequestration (CCS). Like geoengineering, CCS is a “solution for the future that always will be.” It has garnered decades of hype, research, and government funding of prototype projects without doing much of anything to remove carbon and keep it out of the atmosphere. The Biden administration’s Inflation Reduction Act (IRA) contains numerous revenue streams aimed at coping with the climate crisis, including CCS. But it is a mixed bag of good and bad ideas. Beyond Pesticides analyzed the IRA in 2022, lauding the act’s “provision of unprecedented sums to address the existential threats we face related to climate, biodiversity, and health.” These include about $21 billion for “climate smart” agriculture and programs to reduce petrochemically dependent farming. But the analysis also details the many provisions for infeasible and counterproductive projects. Rather than complex and expensive technological projects, the best practitioners of CCS are […]

Study Reinforces Importance of Biodiversity in Agriculture and Ecosystem Health

Wednesday, November 6th, 2024

(Beyond Pesticides, November 6, 2024) An analysis in the International Journal of Research Publication and Reviews emphasizes the role of biodiversity in agriculture, adding to a wide body of science on its importance. The authors, from Western Illinois University in the United States and Rome Business School in Italy, find that biodiversity supports critical ecosystems and organisms needed for sustainable food production. Through literature reviews and case studies, the interconnectedness of agriculture with plant and animal diversity, beneficial insects, soil health, and climate change is highlighted, as well as the need to manage land organically to support biodiversity. Plant and Animal Diversity As the researchers note, “A diverse agricultural system can better absorb shocks and maintain productivity, ensuring food security in the face of uncertainty.” A wide range of species present within ecosystems protects from changing environmental conditions and improves resilience. When farmers use monocultures for their crops, this leads to reduced ecosystem services from beneficial insects and increased vulnerability to pests and diseases. “By contrast, diverse cropping systems can enhance resilience, providing a buffer against environmental changes and fostering sustainable food production,” the authors say. Research shows that higher plant diversity disrupts pest life cycles and promotes beneficial insects, […]
