(Beyond Pesticides, April 25, 2019)Â As reported by Mother Jones, the New York Times (NYT) published, on April 6, a distressing report about a deadly fungus that has been advancing steadily across the world during the past five years. Candida auris is an emerging fungal pathogen that threatens those with compromised or immature immune systems, such as infants, the elderly, people taking steroids for autoimmune disorders, diabetics, those undergoing chemotherapy, and even smokers. Nearly half of those who contract a C. auris infection die within 90 days. One of the factors making this fungus so deadly is that it has developed resistance to existing antifungal medicines, with 90% of infections resistant to one drug, and 30% to two or more. As is true for resistant bacteria, culprits in C. aurisâs development of resistance may be the overuse of antifungal medications in health care and overreliance on fungicides in agriculture. The Centers for Disease Control and Prevention (CDC) has added C. auris to its list of pathogens considered âurgent threats.â It is an âemerging fungal pathogen,â meaning that the incidence of infection has been increasing across multiple countries since it was first recognized in 2009 in Japan (although a different strain had […]

(Beyond Pesticides, April 24, 2019) On April 19, the U.S. Court of Appeals for the 9th Circuit ordered the U.S. Environmental Protection Agency (EPA) to provide a justification for why chlorpyrifos, a neurotoxic insecticide commonly used in agriculture, should remain in the U.S. market. The EPA has 90 days to comply. Chlorpyrifos has been linked to damaging and often irreversible health outcomes in workers, pregnant women, and children. Low levels of exposure early in life can lead to increased risk of learning disabilities including lowered IQ, developmental delay, and attention deficit/hyperactivity disorder (ADHD). Farmworkers and their children are disproportionately affected by the use of this chemical because they are exposed at work, home, and even at school. “While we are moving forward, the tragedy is that children are being exposed to chlorpyrifos, a pesticide science has long shown is unsafe,” said Earthjustice Attorney Patti Goldman in a statement. “We hope Trump’s EPA finally decides to protect the future of countless children and the health of millions of farmworkers.” The battle against chlorpyrifos has been long and drawn out, though there has been significant movement in the last few months. Beyond Pesticides has put together a brief timeline of events: A […]

(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 18, 2019) Organic farming promotes natural resistance to common foodborne human pathogens, according to a study that evaluates the benefit of soil organisms. By protecting valuable species of dung beetles and soil bacteria, organic farming systems naturally act to clean up and decompose potentially pathogen-bearing animal feces. While these natural systems suppr ess pathogens on organic farms, coventional chemical-intensive farms are left with higher levels of fecal residues and are therefore significantly more likely to yield produce carrying such foodborne pathogens as E. coli. The authors emphasize that curbing the spread of common foodborne pathogens could save thousands of lives and prevent millions of illnesses each year. The study, “Organic farming promotes biotic resistance to foodborne human pathogens,” published in the Journal of Applied Ecology, compares dung beetle populations, soil bacteria diversity, and feces removal rates on 70 organic and conventional broccoli farm fields across the west coast of the U.S. In addition to studying field conditions, authors conducted additional microcosm studies to directly test the effects of dung beetles and soil microbes on the suppression of introduced E. coli. Results from field analyses show that organic management practices lead to greater biodiversity among dung beetles and soil […]

(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 8, 2019)Â Officials in Europe and the U.S. focus on banning problem pesticides, raising concerns about their replacements in the face of pesticide-intensive management strategies, while organic advocates call for a systems change in land management. In reference to widespread community bans of Roundup/glyphosate, Cary Gillam, author of Whitewash, told last yearâs Beyond Pesticidesâ Forum, âGlyphosate is the poster child for the bigger pesticide problem.â She continues, âIf it goes away tomorrow, we are not okay.â Because of this, Beyond Pesticides has strategically sought to transform our countryâs approach to pest management, both agricultural and residential/structural, by eliminating a reliance on pesticides and advancing organic management practices that do not rely on toxic inputs. This Daily News Blog post offers updates on progress in the European Union (EU), in the U.S. Congress, and in communities and sates nationwide. The EU is poised to ban clorothalanil, a commonly used â and highly toxic â organochlorine fungicide, The Guardian reported, in mid-to-late May 2019. After a review by the European Food Safety Authority (EFSA), EU states voted to approve a ban. EFSA identified as a chief safety concern the possibility that breakdown products (metabolites) of the compound may cause damage […]

(Beyond Pesticides, April 4, 2019) Contamination of drinking water with toxic breakdown products and risks to fish and and amphibians has led to a ban on the fungicide chlorothalonil in the European Union (EU). While the pesticide will be out of use in the EU next decade, tens of millions of pounds will continue to be sprayed throughout the U.S. unless regulators take action quickly. âThe [chlorothalonil ban] is based on [the European Food Safety Authorityâs] EFSAâs scientific assessment which concluded that the approval criteria do not seem to be satisfied for a wide range of reasons,â a spokeswoman for the European Commission told The Guardian. âGreat concerns are raised in relation to contamination of groundwater by metabolites of the substance.â EFSAâs review of chlorothalonil categorized it as a 1B carcinogen, meaning it âmay cause cancer,â with the most significant risk found for kidney cancer based on laboratory animal studies. Further research was needed into many of the metabolites (break-down substances) created when chlorothalonil degrades. However, regulators determined enough data was present to conclude that these breakdown substances may be genotoxic, with the potential to damage DNA and lead to cancer. European regulators also identified a high acute risk to […]

(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, April 1, 2019) National Organic Standards Board (NOSB) meets next month in Seattle, Washington to debate issues concerning what goes into your organic food. Written comments are due April 4. The format for messaging the NOSB requires copying and pasting comments into regulations.gov, so we apologize that this is not a “single click” action. Please add a personal message about why this is important to you at the top of your comments, if possible. Lend your voice to continuous improvement by learning about issues and submitting comments to regulations.gov (directions below, or click here). From the very beginning, with the passage of the Organic Foods Production Act (OFPA) in 1990, âorganicâ has meant âcontinuous improvement â in organic food production. The primary mechanism for this is the high level of public involvement that comes from twice-annual meetings of the stakeholder board and decisions related to the allowance of substances/materials used in organic production. The second mechanism is the sunset process, which helps move synthetic substances out of organic production as we learn more about hazards and alternatives. Those substances allowed in organic production must be placed on the National List of Allowed and Prohibited Substances and may be re-listed every five […]

(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 27, 2019) Exposure to commonly used pesticides in the womb and during the first year of life is linked to a higher risk of developing autism, according to the study, âPrenatal and infant exposure to ambient pesticides and autism spectrum disorder in children: population based case-control study,â published in the journal BMJ last week. Although the study does not reveal a causal link, it adds to previous literature highlighting autism risks from pesticide exposure, and reinforces calls to limit pesticide exposure during early life critical windows of vulnerability. The authors note their findings âsupport the need to avoid prenatal and infant exposure to pesticides to protect the developing child’s brain.” Researchers used data from Californiaâs records of autism disorder diagnosis and birth rates from 1998 to 2010. Roughly thirty-five thousand healthy patients acted as a control, while scientists identified nearly three thousand patients with an autism diagnosis, of which 445 also displayed a co-occurring intellectual disability. Data was then drawn from Californiaâs pesticide use recording database, and eleven pesticides (glyphosate, chlorpyrifos, diazinon, acephate, malathion, permethrin, bifenthrin, methyl bromide, imidacloprid, avermectin, and myclobutanil) were analyzed for their use within 2000 meters (1.25 miles) of the homes of those […]

(Beyond Pesticides, March 26, 2019) In a study investigating the carcinogenic effects of pesticide exposure by analyzing data on 316,270 farmers and farmworkers in the U.S., Norway, and France, researchers have identified elevated risk for non Hodgkin lymphoma (NHL) and some subtypes, linking glyphosate and large B-cell lymphoma. Other pesticides linked to the disease include the pyrethroid deltamethrin and chronic lymphocytic leukemia/small lymphocytic lymphoma; and terbufos and NHL overall. Researchers also found âinverse associations of NHL overall with the broader groups of organochlorine insecticides and phenoxy herbicides, after adjusting for exposure to other pesticidesâ; such inverse associations were not found with active ingredients within these groups. The research underscores how complex the science of pesticide impacts on human health, and on cancer incidence, can be. To wit: in evaluating 14 different pesticide categories and 33 individual, active chemical ingredients, Maria E. Leon, et al., conclude that associations of pesticides with the development of NHL appear to be (NHL) subtype- and chemical-specific. Published in the International Journal of Epidemiology in mid-March, the study, âPesticide use and risk of non-Hodgkin lymphoid malignancies in agricultural cohorts from France, Norway and the USA: a pooled analysis from the AGRICOH consortium,â uses data from three large cohort […]

(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. Lead authors Elise Berheim, Jonathan Jenks, PhD, […]

(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 11, 2019)Â Â We must stop the expanded commercialization of genetically engineered pesticides. The failure of the U.S. Environmental Protection Agency (EPA) to fully evaluate environmental impacts of gene-manipulating pesticides raises serious concerns in light of the agencyâs ongoing failure to predict ecological effects of pesticides, such as the dramatic decline of pollinators. With the release of a 2019 peer-reviewed scientific article, Environmental Fate of RNA Interference Pesticides: Adsorption and Degradation of Double-Stranded RNA Molecules in Agricultural Soils, on the potential impact on soil and non-target microorganisms in soil, the studyâs co-author, Kimberly Parker, PhD, remarked, âThe ecological risk assessment of these emerging pesticides necessitates an understanding of the fate of dsRNA [double stranded RNA] molecules in receiving environments, among which agricultural soils are most important.â This technology, given that it is systemic to the plant and leaves traces in the soil, can cause widespread indiscriminate poisoningâas has been seen with bees, butterflies, birds, and the larger catastrophic decline of insect populations. Tell your members of Congress that the ecological effects of RNAi gene-manipulating pesticides raise serious questionsâthey have not been fully studied by EPA and, until they are, the agency should issue a moratorium on their release.

(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 6, 2019) After a brief hiatus, Florida Fish and Wildlife Conservation Commission (FWC) is continuing use of aquatic herbicides, including glyphosate, for invasive species management. Public pressure and feedback caused FWC to take a temporary pause from spraying while the commission collected public comment through public hearings and emails from late January through February. FWC ultimately decided to resume spraying invasive species, and points to its improved integrated management system as reducing overall herbicide use. Glyphosate, one of the 17 aquatic herbicides that FWC uses regularly has sparked opposition from environmentalists and the general public due to its wide usage and known adverse effects. According to FWC data, 12,263 pounds of glyphosate-based herbicides were used on Florida’s Lake Okeechobee in 2017. About 175,000 people have signed North Palm Beach photographer and wildlife advocate Jim Abernathyâs petition titled âStop The State-Sanctioned Poisoning of Our Lakes and Rivers!â. The petition decries the use of glyphosate to kill invasive aquatic plants and warns of subsequent nutrient pollution caused by decay. An excess of nutrients (e.g. nitrogen and phosphorus) in water bodies contribute to algal blooms. Eutrophication can eventually result in oxygen depletion and thereby decrease biodiversity. FWC denies that the […]
