(Beyond Pesticides, January 11, 2021) Treatment of chemical companies as clients rather than regulated entities is not new at the Environmental Protection Agency (EPA), but corruption reached new highs during the Trump administration. With a new administration, it is time to end the rule of corporate deception at EPA. This goes beyond the use of the Congressional Review Act to reverse individual rules (adopted in the last six months) that defy scientific findings and compliance with environmental and public health standards. We can no longer rely on bad science and unscrupulous chemical manufacturers that put profits above concerns for the health of people and the environment. EPA must audit pesticide registrants for integrity to scientific process and set a moratorium on future pesticide registration until the agency can assure the public that their science is not corrupt, as it has been in the past. Tell President-elect Biden and Congress to clean up the corruption of science at EPA and set a moratorium on future pesticide registrations—until the agency can assure the public that the chemical manufacturers’ science supporting pesticide registrations is not corrupt. The Midwest Center for Investigative Reporting published a story in early December on yet another example of the […]

(Beyond Pesticides, December 22, 2020) Opening arguments and evidence were filed by a coalition of farmworkers, farmers, and conservationists last week in litigation challenging the U.S. Environmental Protection Agency’s (EPA) re-approval of glyphosate, best known as the active ingredient in Monsanto’s “Roundup” pesticides. The lawsuit charges that the Trump Administration unlawfully ignored cancer risks and ecological damage of glyphosate.  Represented by the Center for Food Safety (CFS), plaintiffs, including the Rural Coalition, Farmworker Association of Florida, Organización en California de Lideres Campesinas, and Beyond Pesticides, filed the federal lawsuit in the Ninth Circuit Court of Appeals in March. The groups seek to have the pesticide prohibited from use or sale because of its unlawful approval. “Farmworkers are on the frontlines of nearly every health and environmental crisis, from the COVID-19 pandemic to climate change, and are particularly at risk of health impacts from pesticide spraying,” said Amy van Saun, senior attorney at CFS. “EPA failed these essential workers. It rejected evidence that glyphosate causes cancer and entirely failed to assess the main way people are exposed at work, through their skin.” The court filing includes volumes of evidence showing how EPA ignored glyphosate’s health risks, including cancer risks, to farmworkers and farmers exposed during spraying. The evidence […]

(Beyond Pesticides, December 21, 2020) The toxic herbicide dicamba is once again at the center of a larger story about states’ authority to regulate pesticides more stringently federal dictates and a response to corporate corruption in the marketing of pesticide products. The Trump EPA (U.S. Environmental Protection Agency) has just made it much harder for state regulations to be more protective than federal rules. It did so via a footnote embedded in dozens of pages of regulatory documents related to EPA’s registration of three new dicamba products.  Tell the Biden transition team that EPA must respect states’ rights to protect people and property in their states. Meanwhile, a report by the Midwest Center for Investigative Reporting found Monsanto and BASF, a German chemical company that worked with Monsanto to launch the system coupling dicamba with resistant crops, knew their dicamba herbicides would cause large-scale damage to fields across the U.S., but decided to push them on unsuspecting farmers anyway, in a bid to corner the soybean and cotton markets with their dicamba-resistant seeds. For nearly 30 years, state regulators have used Section 24 (“Special Local Needs” section) of FIFRA, the Federal, Insecticide, Fungicide and Rodenticide Act—the law that gives EPA […]

(Beyond Pesticides, December 18, 2020) The Midwest Center for Investigative Reporting published a story in early December on yet another example of the corporate malfeasance that exalts profit far above concerns for safety, health, and ecosystems. The Midwest Center’s investigation finds that Monsanto and BASF, makers of the extremely problematic herbicide dicamba, engaged in a variety of deceitful, unethical, and possibly fraudulent practices to enable its use. The bottom line is that the companies knew, before they released dicamba, about the massive damage it would cause — and then put it on the market. Beyond Pesticides has reported on the corporate greed that fuels the downstream public health, environmental, and economic devastation these pesticides cause, and advocated for their removal from the market. Such unscrupulous behavior is not confined to these companies; Bayer (which now owns Monsanto) and Syngenta are also implicated in similar actions related to other pesticides: glyphosate and atrazine, respectively. Over the course of the past couple of decades, large agrochemical corporations have pursued not only extreme market penetration for their toxic products, but also, vertical integration that, in the case of Bayer/Monsanto, “represents a near-monopoly on the agriculture supply chain.” Corporate ownership of the patent on genetically […]

(Beyond Pesticides, November 4, 2020) Despite a recent court ruling voiding the registration of drift-prone dicamba herbicides on genetically engineered (GE) cotton and soybeans, EPA has renewed  the registration of these chemicals. The court’s ruling stated that EPA, “substantially understated risks that it acknowledged and failed entirely to acknowledge other risks,” in regards to the herbicides XtendiMax and Eugenia (dicamba), produced by agrichemical corporations Bayer and BASF for their genetically engineered (GE) crops. In announcing the decision, Administrator Andrew Wheeler said the agency made its decision “[a]fter reviewing substantial amounts of new information, conducting scientific assessments based on the best available science, and carefully considering input from stakeholders.” Yet, it is evident that the most important stakeholders for EPA continues to be chemical corporations. The history of dicamba’s use in GE agriculture reveal this to be the case. In the mid-2010s, Bayer’s Monsanto developed new dicamba-tolerant seeds and received approval to sell them from the U.S. Department of Agriculture. EPA had not yet approved its corresponding herbicide, but nonetheless, Bayer’s Monsanto urged farmers to plant its seed, claiming they would increase yields. The results of this were predictable: farmers began to use older, unapproved dicamba formulations on their new GE […]

(Beyond Pesticides, October 2, 2020) The U.S. Environmental Protection Agency’s (EPA) September 22 announcement asserts that, “despite several years of study, the science addressing neurodevelopmental effects [of the insecticide chlorpyrifos] remains unresolved,” as reported in The New York Times. This conclusion contradicts both ample scientific evidence and the agency’s own findings. Beyond Pesticides has repeatedly advocated for a ban on the use of chlorpyrifos because of the grave risks it poses. This organophosphate pesticide is used on approximately 60 different crops, including almonds, cotton, citrus fruits, grapes, corn, broccoli, sugar beets, peaches, and nectarines. It is also commonly employed for mosquito-borne disease control, and on some kinds of managed turf, including golf courses. Exposure to the pesticide has been identified repeatedly as problematic. Most residential uses were taken off the market in 2000, after the manufacturer, DowDupont (now Corteva) was faced with EPA action. Chlorpyrifos is a cholinesterase inhibitor that binds irreversibly to the receptor sites of acetylcholinesterase (AChE), an enzyme that is critical to normal nerve impulse transmission. In so doing, chlorpyrifos inactivates the enzyme, damages the central and peripheral nervous systems, and disrupts neurological activity. The compound is associated with harmful reproductive, renal, hepatic, and endocrine disrupting effects, and most […]

(Beyond Pesticides, September 23, 2020) Multinational agrichemical corporation Bayer coordinated with the U.S. government to pressure Thailand to drop plans to ban glyphosate use, according to documents obtained by the Center for Biological Diversity (CBD). CBD is now suing the Trump Administration after it refused to release additional documents pertaining to the pressure campaign. The incident is the latest example of an administration that has allowed corporate interests to dictate American governmental action on toxic pesticides. The documents reveal that the October 2019 letter that U.S. Department of Agriculture (USDA) Undersecretary Ted McKinney sent to Thailand’s Prime Minister Prayuth Chan-ocha pushing back on the country’s plan to ban glyphosate came shortly after emails Bayer sent to U.S. officials. In September and October 2019, Bayer’s Jim Travis asked the U.S. to act on its behalf in defense of the company’s glyphosate products. Emails reveal that Mr. Travis also collected intelligence on the personal motivations of Thailand’s deputy agriculture minister, including whether she was “a diehard advocate of organic food; and/or staunch environmentalist who eschews all synthetic chemical applications.” Reports indicate that the U.S. government brought up the issue of glyphosate during trade talks in the context of considerations to revoke Thailand’s […]

(Beyond Pesticides, September 22, 2020) Use of the highly hazardous, endocrine disrupting weed killer atrazine is likely to expand following a decision made earlier this month by the U.S. Environmental Protection Agency (EPA). Under the guise of “regulatory certainty,” the agency is reapproving use of this notorious herbicide, as well as its cousins simazine and propazine in the triazine family of chemicals, with fewer safeguards for public health, particularly young children. Advocates are incensed by the decision and vow to continue to put pressure on the agency. “Use of this extremely dangerous pesticide should be banned, not expanded,” Nathan Donley, PhD, a senior scientist at the Center for Biological Diversity said in a press release. “This disgusting decision directly endangers the health of millions of Americans.” Beyond Pesticides has long argued against the continued use of the triazine herbicides, which includes atrazine. Triazines are well known to interfere with the body’s endocrine, or hormonal system. Disruptions within this delicately balanced process in the body can result in a range of ill health effects, including cancer, reproductive dysfunction, and developmental harm. These weedkillers interfere with the pituitary gland’s release of luteinizing hormones, which regulate the function of female ovaries and male gonads. In comments written by Beyond Pesticides to EPA, the organization notes, “Of the numerous adverse effects associated with this disruption, […]

(Beyond Pesticides, August 28, 2020) The Environmental Protection Agency (EPA) has granted “emergency” permission to the State of Texas to allow the use of SurfaceWise®2, an unregistered pesticide, as an anti-viral surface coating. The manufacturer, Allied Bioscience, says the compound can kill coronaviruses (including SARS-CoV-2) starting at two hours post application and for up to seven days, but it is not included on EPA’s List N, of disinfectants effective against SARS-CoV-2. EPA has permitted this use via the authority of Section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), which allows for “emergency” use of non-registered pesticides, typically to deal with extreme threats to agricultural activities. It is rarely used for public health emergencies. Beyond Pesticides recognizes the need for protection from transmission of the novel coronavirus, and maintains that it ought to and can be done without exposing people to toxic synthetic pesticides that have not undergone evaluation for safety. See Beyond Pesticides’ guidance on effective and safe precautions against the novel coronavirus. The Texas Department of Agriculture secured the EPA exemption, making the state the first to do so; Allied BioScience is pursuing this emergency waiver across all 50 states. The exemption grants American Airlines and two health […]

(Beyond Pesticides, August 17, 2020) Once numbering in the millions, barely 29,000 western monarch butterflies were found in California at last count. Pesticides pack a one-two punch against monarchs. Insecticides—particularly neonicotinoids—poison the caterpillars and butterflies as they feed. Glyphosate—the active ingredient in Bayer-Monsanto’s Roundup® — is wiping out milkweed, the only food source for monarch caterpillars. This has contributed to monarchs’ 90% decline in the past 20 years alone. They could vanish within our lifetimes. Home and garden stores like Lowe’s and Home Depot can play a huge role in ending the use of this toxic pesticide in our backyards and across the country. Already, Lowe’s is removing neonicotinoid products from its live plant offerings and store shelves, and Home Depot is eliminating use of neonicotinoids in its live plant offerings. They could stop selling Roundup®. More importantly, they could encourage organic practices through their product offerings and consumer education. Ask Home Depot and Lowe’s to get Roundup® off their shelves and promote and educate on organic! Companies like Lowe’s and Home Depot could be leaders by removing products containing glyphosate/Roundup® from their physical stores and online—following the example of their competitor, Costco. This would send a powerful message to Bayer […]

(Beyond Pesticides, August 13, 2020) Levels of the notorious herbicide compound glyphosate in the human body are reduced by 70% through a one-week switch to an organic diet, finds a new, peer-reviewed study published in August 2020 in the journal Environmental Research. This result emphasizes both the ubiquity of this compound in the human body, and diet as the primary source of exposure for most people. It also adds to the evidence for Beyond Pesticides’ assertions that: (1) chemical-intensive agriculture must be abandoned, for a variety of reasons that include human health, and (2) in the lead-up to a transition to organic and regenerative agriculture, consuming organic foods as much as is practicable is powerful protection from glyphosate, and from the assault of multiple chemical pesticides to which most people are exposed. Glyphosate is the active ingredient in the popular weed killer RoundupTM, which has been used intensively in the U.S. and around the world, especially during the last couple of decades. It is very commonly used on crops grown from genetically engineered (GE) companion seeds for a variety of staple crops (e.g., soybeans, cotton, and corn). These GE seeds are glyphosate-tolerant, whose attribute has allowed growers to apply the herbicide and […]

(Beyond Pesticides, August 12, 2020) The herbicide atrazine can interfere with the health and reproduction of marsupials (including kangaroos and opossums) kangaroo, Virginia opossum, according to research published in the journal Reproduction, Fertility, and Development. Although the research focuses on the health of the Australian wallaby, the data is relevant for the only marsupial in the United States, the opossum. Unfortunately, the research is no surprise, as atrazine has a long history of displaying endocrine (hormone) disrupting properties, affecting sex and reproduction in a broad range of species. The study, under the auspices of University of Melbourne Animal Experimentation and Ethics Committee, exposed pregnant female adult wallabies to atrazine through gestation, birth, and lactation. Doses of the weedkiller were slightly higher than real world models, but according to researchers, “It is quite possible a wild animal could get such an exposure.” Researchers then euthanized the newborn wallabies to study atrazine’s effects. The gonads and phallus of young wallabies were analyzed for any physiological changes or impacts to gene expression. Researchers found changes to the gene expression necessary for basic function of the testis, and a significant reduction in phallus length. “These results demonstrate that [atrazine] exposure during gestation and lactation can […]

(Beyond Pesticides, August 11, 2020) Petitioners who mounted a legal challenge to the Environmental Protection Agency’s (EPA’s) registration of Enlist Duo, a relatively new and highly toxic pesticide product, recently learned of a mixed decision from the U.S. Ninth Circuit Court of Appeals in the case. The good news is that Judge Ryan D. Nelson, writing the opinion for the court, found that EPA, in registering the herbicide Enlist Duo, had failed to protect monarch butterflies, which are under consideration as a threatened species under the Endangered Species Act (ESA). On the other and disturbing hand, the court concluded that EPA registration of the product was otherwise lawful — which means that this toxic compound will for now remain on the market. As one of the plaintiffs in the case, Beyond Pesticides is adamant that this product should not be registered for use by EPA. George Kimbrell, Legal Director of Center for Food Safety and Lead Counsel for the plaintiffs, commented on the decision in the organization’s July 22 press release on the decision: “The panel majority’s unprecedented decision is contrary to controlling law and established science, and Center for Food Safety is analyzing all legal options, including seeking a full […]

(Beyond Pesticides, July 1, 2020) As the U.S. is subject to searing criticism for inadequately regulated hazardous pesticides domestically, administration officials are standing in the way as other countries’ work toward modest reforms. According to a report published in Reuters, the U.S. is standing alongside the corrupt Bolsonaro administration in Brazil to oppose Thailand’s efforts to protect its citizens from highly toxic pesticides used in food production. Both countries launched separate complaints to the World Trade Organization after Thailand announced it would ban imports of the brain-damaging insecticide chlorpyrifos and weedkiller paraquat, which has been strongly linked to Parkinson’s disease. On June 1, Thailand added paraquat and chlorpyrifos to its list of most hazardous substances. This listing initiated a follow-on regulation that banned the import of these substances on food, set to take effect in mid-July. Thailand has been feeling the brunt of U.S. diplomatic pressure since it first proposed restrictions on toxic chemicals late last year. By December, the U.S. was able to get Bangkok to remove glyphosate from its proposal, and delay the listing of paraquat and chlorpyrifos until June. But as the current situation shows, the U.S. had no plans to stop pressuring the Bangkok government after […]

(Beyond Pesticides, June 29, 2020) Bayer’s Monsanto is requesting non-regulated status for corn that will increase the use of drift-prone and toxic herbicides. This means that the planting of a new genetically engineered (GE) variety of corn, which requires substantial weed killer use, will not be restricted in any way. The syndrome of ‘more-corn, more-pesticides, more-poisoning, more-contamination’ must stop—as we effect an urgent systemic transformation to productive and profitable organic production practices. Because USDA is proposing to allow a new herbicide-dependent crop under the Plant Protection Act, the agency must, but does not, consider the adverse impacts associated with the production practices on other plants and the effects on the soil in which they are grown. Business as usual is not an option for a livable future. Sign the petition. Tell USDA we don’t need more use of 2,4-D, Dicamba, and other toxic herbicides associated with the planting of new GE corn. Bayer-Monsanto has developed multi-herbicide tolerant MON 87429 maize, which is tolerant to the herbicides 2,4-D, dicamba, glyphosate, glufosinate, and aryloxyphenoxypropionate (AOPP) acetyl coenzyme A carboxylase (ACCase) inhibitors (so-called “FOP” herbicides, such as quizalofop). Now the company wants this corn to be deregulated—allowing it to be planted and the herbicides […]

(Beyond Pesticides, June 26, 2020) A court decision in California, challenging a cancer warning on products containing the weed killer glyphosate, highlights the distinct  ways in which scientific findings are applied under regulatory standards, in toxic tort cases evaluated by juries, and by consumers in the marketplace. These differences came into focus as a U.S. court quashed California’s decision to require cancer warning labels on glyphosate products on June 22. The ruling, by Judge William Shubb of the U.S. District Court for the Eastern District of California, bars the state from requiring labeling that warns of potential carcinogenicity on such herbicides. The World Health Organization’s International Agency for Research on Cancer (IARC) in 2015 classified glyphosate as a probable human carcinogen. At this point, Monsanto began a worldwide campaign to challenge glyphosate’s cancer classification. The IARC finding spurred the California Office of Environmental Health Hazard Assessment, in the same year, to announce that glyphosate would be listed as a probable cancer-causing chemical under California’s Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65). With that announcement came another: the state would mandate that cancer warning labels be applied to glyphosate-based products in the state when any of four […]

(Beyond Pesticides, June 25, 2020) Facing approximately 125,000 lawsuits on cancer caused by the weed killer Roundup™ (glyphosate), Bayer/Monsanto announced yesterday that it will pay up to $10.9 billion to resolve current and potential future litigation. According to Bayer, the settlement will “bring closure” to approximately 75% of current Roundup™ litigation. “The company will make a payment of $8.8 billion to $9.6 billion to resolve the current Roundup™ litigation, including an allowance expected to cover unresolved claims, and $1.25 billion to support a separate class agreement to address potential future litigation,” according to Bayer’s press release. At the same time the company announced a $400 million settlement with farmers whose crops have been damaged by the weed killer dicamba and $820 million for PCB water litigation. Bayer is a German multinational pharmaceutical and chemical company that purchased Monsanto for $63 billion in 2018. Bayer’s stock price increased by 2.5% after the news of the settlements. Bayer Settles, but Defends the Safety of Roundup™As expected, Bayer is not acknowledging any harm caused by glyphosate. According to chief executive officer of Bayer, Werner Baumann, “The decision to resolve the Roundup™ litigation enables us to focus fully on the critical supply of healthcare […]

(Beyond Pesticides, June 9, 2020) Use of the weed killer dicamba on genetically engineered (GE) cotton and soybeans is now prohibited after a federal court ruling against the U.S. Environmental Protection Agency (EPA) last week. A coalition of conservation groups filed suit in 2018 after EPA renewed a conditional registration for dicamba’s ‘over the top’ (OTT) use on GE cotton and soy developed to tolerate repeated sprayings of the herbicide. “For the thousands of farmers whose fields were damaged or destroyed by dicamba drift despite our warnings, the National Family Farm Coalition is pleased with today’s ruling,” said National Family Farm Coalition president Jim Goodman in a press release. First registered in the late 1960s, dicamba has been linked to cancer, reproductive effects, neurotoxicity, birth defects, and kidney and liver damage. It is also toxic to birds, fish and other aquatic organisms, and known to leach into waterways after an application. It is a notoriously drift-prone herbicide. Studies and court filings show dicamba able to drift well over a mile off-site after an application. Bayer’s Monsanto thought they could solve this problem. The “Roundup Ready” GE agricultural model the company developed, with crops engineered to tolerate recurrent applications of their […]

(Beyond Pesticides, May 6, 2020) The Trump Administration announced late last month that it is waiving a requirement that multinational chemical company Syngenta-Chemchina continue to monitor Midwest waterways for the presence of the weedkiller atrazine throughout 2020. While rationalized by the Administration as “due to the unanticipated impact of Covid-19,” the move will instead put residents health at increased risk. Atrazine is one of 78 pesticides that has been linked to the development of respiratory ailments like wheeze. “The public will now have no idea whether dangerous levels of atrazine are reaching rivers and streams throughout the Midwest. That’s absurd and reckless,” said Nathan Donley, PhD a senior scientist with the Center for Biological Diversity. “Syngenta should suspend the sale and use of this extremely toxic pesticide until it can safely ensure it’s not polluting Corn Belt waterways.” Syngenta, which merged with state-owned China Nation Chemical Corporation (Chemchina) in 2016, has been bound by EPA to monitor Midwestern waterways since a 2004 review by the agency. This is because atrazine is a potent groundwater contaminant. Just two years ago, an analysis by the Environmental Working Group found atrazine to be exceeding legal limits in drinking water for many Midwestern states. […]

(Beyond Pesticides, March 25, 2020) The Trump administration’s U.S. Fish and Wildlife Service (USFWS) is moving forward with a proposal to grow genetically engineered crops (GECs) on national wildlife refuges in the Southeast United States. The draft environmental assessment allows wildlife to consume pesticide-laden produce, considers chemical-intensive genetically engineered crops no less damaging to the environment than “non-use of GECs,” and permits and escalation of climate change with toxic pesticide use increases. USFW’s proposal fails to mention the success of organic agriculture and consider it as one of the alternative management strategies. The proposal is up for public comment until April 10, 2020. In 2014, public pressure and lawsuits by environmental groups led to the Obama administration’s decision to phase out GE crops and ban neonicotinoid insecticide use on national wildlife refuges. On August 2, 2018, the Trump administration’s USFWS issued a memorandum that reversed the prohibition. The reversal allows the refuge system to make decisions on the use of GECs and neonics on a case-by-case basis in compliance with the National Environmental Policy Act (NEPA), which is also under attack by the Trump administration. The Center for Biological Diversity, Center for Food Safety, and others quickly challenged the 2018 […]

(Beyond Pesticides, March 24, 2020) Last week, Maryland became the latest state to prohibit use of the brain-damaging insecticide chlorpyrifos, after a measure cleared both the state Senate and House. Although the legislation implements a limited ban that sunsets after four years, advocates consider this action a step in the right direction that will protect the health and safety of Maryland residents. “Even amidst our current public health crisis, the Maryland legislature acted to protect all Marylanders’ health for years to come by banning this toxic pesticide, and we are so grateful,” said Ruth Berlin, Executive Director of the Maryland Pesticide Education Network to WBOC. Chlorpyrifos is an organophosphate insecticide known to inhibit the proper nerve functioning by affecting the enzyme acetylcholine esterase. The impacts of this pesticide are particularly concerning for young children, as research finds that children exposed to high levels of chlorpyrifos had mental development delays, attention problems, attention-deficit/hyperactivity disorder problems, and pervasive developmental disorder problems at three years of age. While Maryland is the fourth state to restrict the use of chlorpyrifos, it is the second to implement these restrictions through legislation. In California, the state Department of Pesticide Regulation is implementing a phase out of […]

(Beyond Pesticides, March 23, 2020) Ignoring science to side with Monsanto/Bayer, EPA has repeatedly failed to assess glyphosate’s impacts on public health and endangered species. Last week, a broad coalition of farmworkers, farmers, and conservationists, filed a federal lawsuit against the Environmental Protection Agency (EPA) over its January 2020 re-approval of the pesticide glyphosate, best known as the active ingredient in Monsanto’s Roundup pesticides. With Center for Food Safety (CFS) serving as legal counsel, the suing organizations are  Beyond Pesticides, the Rural Coalition, Organización en California de Lideres Campesinas, and the Farmworker Association of Florida. While EPA defends glyphosate, juries in several cases have found it to cause cancer, ruling in favor of those impacted by exposure. Glyphosate formulations like Roundup are also well-established as having numerous damaging environmental impacts. After a registration review process spanning over a decade, EPA allowed the continued marketing of the pesticide despite the agency’s failure to fully assess glyphosate’s hormone-disrupting potential or its effects on threatened and endangered species. The review began in 2009, has already taken 11 years, without a full assessment of the widespread harmful impacts on people and the environment in that time period. “EPA’s half-completed, biased, and unlawful approval sacrifices the […]

Experimental ponds in Gault Nature Reserve. Photo credit: Vincent Fugère (Beyond Pesticides, March 5, 2020) A new study conducted by researchers at McGill University investigated phytoplankton (microscopic algae) response and resilience to Roundup exposure. “Community rescue in experimental phytoplankton communities facing severe herbicide pollution” was published in Nature Ecology & Evolution. Researchers found that algae can develop resistance to contamination, but surviving phytoplankton communities are much less diverse. Diversity loss is cause for concern as it could hinder adaptation to other potential stressors, such as climate change.  Using experimental ponds, researchers first exposed some phytoplankton communities to low levels of Roundup over time, then dosed the ponds with a lethal amount.  Groups that had been given low doses survived the lethal phase whereas unpolluted, control ponds did not. Researchers observed “community rescue,” where genetic changes avert population collapse in a lethal environment. In fact, glyphosate eventually became a fertilizer in resistant ponds as it is a significant source of phosphorus. Other studies, too, have noted that phosphorous loading is an overlooked impact of glyphosate contamination. Phytoplankton matter because their disruption can cause a trophic cascade and impact other organisms. “These tiny species at the bottom of the food chain play […]
