(Beyond Pesticides, September 24, 2020) A new report by the U.S. Geological Survey (USGS), National Water-Quality Assessment (NAWQA) Project, reveals the presence of pesticides is widespread in U.S. rivers and streams, with over almost 90 percent of water samples containing at least five or more different pesticides. Pesticide contamination in waterways is historically commonplace as a 1998 USGS analysis revealed pesticides are commonly found in all U.S. waterways, with at least one pesticide detectable. Thousands of tons of pesticides enter rivers and streams around the U.S. from agricultural and nonagricultural sources, which contaminate essential drinking water sources, such as surface water and groundwater. As the number of pesticides in waterways increases, it has detrimental impacts on aquatic ecosystem health, especially as some pesticides work synergistically with others to increase the severity of the effect. Reports like these are a significant tool in determining appropriate regulatory action to protect human, animal, and environmental health. USGS concludes, âIdentification of primary contributors to toxicity could aid efforts to improve the quality of rivers and streams to support aquatic life.â Water is the most abundant and important chemical compound on earth, essential to survival and the main component of all living things. Less than three percent of that water […]

(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 Thailandâs Prime Minister Prayuth Chan-ocha pushing back on the countryâs plan to ban glyphosate came shortly after emails Bayer sent to U.S. officials. In September and October 2019, Bayerâs Jim Travis asked the U.S. to act on its behalf in defense of the companyâs glyphosate products. Emails reveal that Mr. Travis also collected intelligence on the personal motivations of Thailandâs deputy agriculture minister, including whether she was âa diehard advocate of organic food; and/or staunch environmentalist who eschews all synthetic chemical applications.â Reports indicate that the U.S. government brought up the issue of glyphosate during trade talks in the context of considerations to revoke Thailandâs […]

(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 âregulatory certainty,â 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. âUse of this extremely dangerous pesticide should be banned, not expanded,â Nathan Donley, PhD, a senior scientist at the Center for Biological Diversity said in a press release. âThis disgusting decision directly endangers the health of millions of Americans.â Beyond Pesticides has long argued against the continued use of the triazine herbicides, which includes atrazine. Triazines are well known to interfere with the bodyâs 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 glandâs 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, âOf the numerous adverse effects associated with this disruption, […]

(Beyond Pesticides, September 21, 2020)Â The National Organic Standards Board (NOSB) meets online October 28-30 to debate issuesâafter hearing public comment October 20 and 22âconcerning how organic food is produced. Written comments are due October 1. They must be submitted through Regulations.gov. Everywhere we look, we see signs of ecological collapseâwildfires, the insect apocalypse, crashing populations of marine organisms, organisms large and small entangled in plastic, more and more species at risk, rising global temperatures, unusual weather patterns, horrific storms, and pandemics. As we focus on one of the most blatant examples of environmental abuseâthe dispersal of toxic chemicals across the landscapeâit is important to seek a solution. Organic can be a big part of the solution, but only if it doesnât stray from its core values and practices. Tell the National Organic Standards Board to support core organic values. From its very beginnings, the organic sector has been driven by an alliance of farmers and consumers who defined the organic standards as a holistic approach to protecting health and the environment, with a deep conviction that food production could operate in sync with nature and be mindful of its interrelationship with the natural worldâprotecting and enhancing the quality of air, […]

(Beyond Pesticides, September 18, 2020)Â In late August, Consumer Reports magazine (CR) issued a report titled, âStop Eating Pesticides,â which offers consumers a rating system CR developed and employed to help them âget the health benefits from fruits and vegetables while minimizing [the] risk from toxic chemicals.â In addition to providing its analysis and ratings of the pesticide risk of a variety of produce items, CR recommends eating organically grown and raised foods whenever possible. It also makes a host of recommendations on federal pesticide policies and emphasizes the importance of maintaining the integrity of the National Organic Standards (of the USDA-housed National Organic Program). Beyond Pesticides appreciates that this mainstream publication has arrived at many shared, science-based assessments of the risks of pesticides. That said, a wholesale transition to organic and regenerative agriculture â rather than making the public figure out which fruits and vegetables are âsaferâ or âless safeâ â is the real answer to the health risks of pesticides in the food supply, according to Beyond Pesticides. The CR analysis used data from the U.S. Department of Agricultureâs (USDAâs) Pesticide Data Program for 2014â2018. Those pesticide residue data were compiled from tests of approximately 450 pesticides across 24,000 […]

(Beyond Pesticides, September 17, 2020) The apparel industry becomes the latest contributor to global biodiversity loss, directly linking soil degradation, natural ecosystems destruction, and environmental pollution with apparel supply chains, according to the report, âBiodiversity: The next frontier in sustainable fashion,â by McKinsey & Company. Although there are many studies on the fashion industryâs impact on climate change, much less research discusses the impact the industry has on biodiversity. The globe is currently going through the Holocene Extinction, Earthâs 6th mass extinction, with one million species of plants and animals at risk of extinction. With the increasing rate of biodiversity loss, advocates say it is essential for government agencies to hold the fashion industry accountable for the direct (i.e., excessive agrochemical use, water consumption) and indirect (i.e., water pollution from run-off) impacts on the environment, not only to protect the well-being of animals, but humans, as well. Researchers in the study note, âWe expect biodiversity to become an even greater concern for consumers and investors in the coming years. Covid-19, instead of slowing the trend, has accelerated itâperhaps because people now understand more deeply that human and animal ecosystems are interdependent. Itâs time for the apparel industry, which to date has contributed heavily […]

(Beyond Pesticides, September 16, 2020) Disease carrying mosquitoes are more likely to flourish in areas being altered by human activities, according to new research published by scientists at Oregon State University. With climate change facilitating the spread of mosquitoes into new regions throughout the world, it is critical to understand the drivers of mosquito-borne disease in order to establish effective mitigation measures. “People care a lot about what environment a lion needs to succeed in; we’ve researched that extensively. But people don’t do that with mosquitoes. We don’t understand them as a group of species and how their ecology differs between species,” said study co-author Brianna Beechler, PhD, a disease ecologist and assistant professor of research in Oregon State University’s Carlson College of Veterinary Medicine. Authors of the study note that most mosquito collection occurs opportunistically, with samples taken at known mosquito breeding sites. To better understand mosquito spatial ecology, scientists conducted paired sampling at locations inside and outside South Africaâs Kruger National Park, the largest nature preserve in the country. Each sample location inside the park was paired with another sample from a similar location (in terms of landscape and climatic conditions) in developing areas outside of the park. […]

(Beyond Pesticides, September 15, 2020) Both wild and captive primates are being exposed to hazardous pesticides and flame retardants, according to research published this month in the journal Environmental Science and Technology. This is the first study to look at the threat anthropogenic (man-made) chemicals may present for this important order of animals. “We think a lot about habitat disturbance, logging, and hunting as threats to these species, while pollution has been overlooked,” study co-author Michael Wasserman, told Environmental Health News (EHN). Scientists conducted their research by first obtaining fecal samples from three distinct primate populations: captive baboons from an Indiana zoo, wild howler monkeys from a research station in Costa Rica, and wild chimpanzees, red-tailed monkeys, and red colobus monkeys from a Ugandan national park. Samples were then tested for a range of chemicals, including 50 pesticides, and nearly 70 flame retardants. Scientists discovered legacy pesticides (such as heptachlor, DDT, hexachlorohexane, chlordane, and related compounds) in every species tested, with the highest levels found in red colobus and red-tailed monkeys. In particular, DDT and its related compounds (DDD and DDE) were found to be widespread, with red colobus monkeys registering a median of 260 ppb DDE in its waste. […]

(Beyond Pesticides, September 14, 2020) As Congress returns to Washington this week, it is overdue to pass critical pandemic aid for families and communities, including helping small and mid-scale farms and ranches, farmers markets, and local food businesses address the impacts of the Covid-19 pandemic. The Local and Regional Farmer and Market Support Act (H.R. 8096), introduced by Rep. Alma Adams of North Carolina, will help meet the needs of farmers who have been left out. Please urge your Congressional Representative co-sponsor this bill. While farmers struggle to feed their communities during the ongoing coronavirus pandemic, many have not received support for critical safety and technology needs. Billions in federal aid through the Coronavirus Food Assistance Program (CFAP) has gone out, but failed to reach all farmersâparticularly direct marketing farmers and ranchers, diversified farmers, and folks who are Black, Indigenous, and people of color. Local and regional food enterprises have worked to supply food through farmers markets, food hubs, CSAs, and more, but have not received the support given to larger enterprises. Tell Congress to Help Farmers of Color and Small and Medium-Sized Farms Selling in Local Food Markets. The Local and Regional Farmer and Market Support Act: Creates an alternative coronavirus relief payment program for farmers […]

(Beyond Pesticides, September 11, 2020) In late August, the National Black Farmers Association filed suit against the chemical company Bayer/Monsanto, seeking to stop the sale of its ubiquitous, glyphosate-based herbicide, Roundup. According to the Midwest Center for Investigative Reporting, the lawsuit argues that Black farmers are, essentially, forced to use Roundup and incur the risks of developing non-Hodgkin Lymphoma or other cancers (or health impacts) because of the exigencies of the pesticide and biotech industry âgripâ on agriculture in the U.S. The suit maintains that Bayer (which owns Monsanto, the original manufacturer of Roundup) knowingly failed, and continues to fail, to warn farmers adequately about the dangers of the pesticide. In a Labor Day Daily News post, Beyond Pesticides noted that current pesticide laws result in disproportionate impacts on workers, including agricultural workers of color. Beyond Pesticides is committed to addressing the conditions that give rise to disproportionate harm and to working in broad coalitions to correct them. Many countries have banned use of Roundup, largely because of glyphosateâs strong links to many health issues, including cancer, endocrine disruption, Parkinsonâs Disease, and reproductive and immunological anomalies. The compound is regarded as carcinogenic by the International Agency for Research on Cancer […]

(Beyond Pesticides, September 10, 2020) A new analysis by Science of Cannabis Laboratories Inc. (SC Labs) finds detectable concentrations of pesticides and heavy metals in rolling papers, with hemp/blunt wraps and cellulose-based rolling papers containing the highest levels of contaminants. The analysis follows a SC Labsâ finding of high levels of chlorpyrifosâa neurotoxic, organophosphate insecticideâin the rolling paper of pre-rolled cannabis, which was undergoing compliance testing. Although the rolling paper regulations generally track standards for toxic tobacco products (which means there is very little meaningful regulation), the rolling paper use with cannabis may add an addition layer of scrutiny since some statewide cannabis regulations and independent certifications adhere to stricter guidelines similar to organic practices. Researchers note the goals of the experiment âwere to assess the exposure risks to the consumer as well as identify any potential liabilities for cannabis producers who use these products to make their pre-roll products.â This report, and others like it, are significant as cannabis use expands in in the U.S. and around the world, and given that one of the most popular ways to consume cannabis product is as a rolled cigarette. Study author and president of SC Labs Josh Wurzer, Ph.D., said, âThis [issue] is something that cannabis and paper […]

(Beyond Pesticides, September 9, 2020) Late last month the California legislature voted to ban, with limited exceptions, the use of highly toxic rat poisons. The California Ecosystems Protection Act of 2020, AB 1788, was passed after over a year of advocacy by groups and individuals concerned about the impact of second-generation anticoagulant rodenticides (SGAR) on state and local wildlife. Proponents of the legislation are advocating that lawmakers in other states follow Californiaâs lead by passing similar legislation. The bill must be signed by Governor Gavin Newsom or allow the bill to become a law without his signature by September 30, 2020. The legislation hones in on the use of SGARs, specifically the chemicals brodifacoum, bromadiolone, difenacoum, and difethialone, which present significant hazards to non-target wildlife. Unlike the first generation of blood thinning rodenticides on the market (such as chlorophacinone, warfarin, and diphacinone, which present their own hazards), SGARs cannot be quickly excreted by the body and can deal a lethal dose to rodents in a single feeding. However, SGAR-poisoned rodents do not die immediately, and are often left lethargic and exposed to the elements. This makes them easy prey for birds and mammals. In California, SGARs gained considerable attention for […]

(Beyond Pesticides, September 8, 2020) Canada should be in accordance with international treaty to eliminate persistent pollutants. Canada is considering the elimination of one of the worst persistent pollutantsâpentachlorophenol (penta)âthat dot our landscape in utility poles and railroad ties. This wood preservativeâa cancer-causing chemical with dioxin, furans, and hexachlorobenzene that causes health and environmental degradationâhas no place in society as we struggle with shared global challenges of public and worker health threats, the climate crisis, and biodiversity decline. We have a chance to urge Canada to move ahead with a pentachlorophenol ban, joining with Mexico to show leadership in the protection of health and the environmentâsomething the U.S. has not done. Tell Canada to ban pentachlorophenol. Canada’s Pest Management Regulatory Agency (PMRA) is accepting comments on a proposal to ban the all uses of penta in Canada. Comments are due September 13. Canada is a signatory to the Stockholm Convention on Persistent Organic Pollutants, which voted 90-2 to ban penta in 2015. The United States is not a signatory to the Stockholm Convention and still allows the use of penta on utility poles and other âwood that is subject to decay or insect infestation, including supporting structures in contact with […]

(Beyond Pesticides, September 7, 2020)Â On Labor Day during this coronavirus pandemic, it is especially appropriate that we thank all essential workersâbut thanks are not enough. We must redouble our efforts to eliminate the racial and economic inequities in our society that contribute to disproportionate risk to the health and well-being of workers, especially people of color. As the commentary in New York Magazine by Sarah Jones states, â[T]okens of appreciation are just that: tokens, which signal nothing deeper than gratitude. That doesnât pay anyoneâs rent.â And, all our gratitude does not protect anyoneâs health. Nobody should have to risk their health for a job. As we as a nation recognize that systemic change is needed to fight racial and economic injustice, we are faced with questions that go to the core of our societyâthe distribution of wealth, a livable wage, investment in and access to education and health care, and an environment that sustains life. It could be said that an environmental organization, like Beyond Pesticides, that works on environmental, health, and agriculture and land management issues should âstay in its laneâ and not delve into broader issues that address our social and economic structure. However, the events of the […]

(Beyond Pesticides, September 4, 2020)Â When pesticide drift is investigated, it is most often drift from agricultural fields that is examined. A new study shows that off-target drift of pesticides from greenhouses is also a reality. This research deduced such drift of organophosphate and carbamate pesticides from crop applications done in Ecuadoran floriculture greenhouses by evaluating the acetylcholinesterase enzyme (AChE) activity, necessary to the transmission of nerve impulses, in children residing nearby. The team finds that children living in homes near greenhouses in which these insecticides (widely recognized as cholinesterase inhibitors) are used exhibit reduced activity of this enzyme and abnormal functioning of the nervous system. Beyond Pesticides has monitored the pesticide drift issue intensively, and has long advocated for far better protections for farmworkers. This new information connects those issues, and expands the âdriftâ concerns to include risks to people working in greenhouses, and to those, especially children, who happen to live near greenhouse-type structures in which these toxic chemicals are used. The study evaluates data during three separate periods (2008, April 2016, and JulyâOctober 2016) on 623 children, aged 4â17, living in floricultural communities in Ecuador. The research is part of the study of the Secondary Exposure to Pesticides […]

(Beyond Pesticides, September 3, 2020) Occupational exposure to pollutants including, those from wood burning, pesticides, metals, and vehicle combustion, increases the risk of developing heart abnormalities among Latinx individuals, according to new research published in the Journal of the American Heart Association. Although previous research focuses on the impact of pollutants on human health from occupational or residential exposure, this study highlights the risk chemical exposure can have on communities, especially for those underrepresented in conventional occupational health studies, such as those with Hispanic or Latinx backgrounds. People of color communities are already at greater risk of exposure to environmental and health harms, such as pesticide pollution, which has been identified as environmental racism. Additionally, not only are people of color at risk of developing various, serious health issues associated with additional or cumulative pesticide exposure, they disproportionately face an elevated risk from Covid-19 as essential workers or family members of those workers. According to the researchers, âThe objective of this study was to assess the relationship between occupational exposure to hazardous substances and cardiac structure and function in Hispanic/Latino participants in ECHOâSOL (Echocardiographic Study of Latinos).â It is significant as it highlights the regular/routine exposure to environmental pollutants, including pollution from […]

(Beyond Pesticides, September 2, 2020) Itâs being called the Monarch Massacreâhundreds of monarch butterflies found dead after the Vector Control Department of Cass County, North Dakota aerially sprayed the county for mosquito control. This incident occurred during a moment in history that is seeing monarchs at the edge of extinction, with the number of monarch butterflies overwintering in Mexico having declined 53% from last year, according to a count conducted by World Wildlife Fund (WWF) Mexico. This tragedy happened as the nation and the world are experiencing an insect apocalypse and severe biodiversity decline, threatening the web of life. (See Study Predicts Demise of Insects within Decades if Pesticide Dependence Continues.) While it is critical that steps be taken by communities nationwide to protect their local ecology, the incident generated a response from Cass County that claims that the insecticides used are âthe lowest toxicity products on the market for mosquito control,â and points to the âmonarch migration [that] is a sporadic event that unfortunately occurred during the latest adult mosquito control application.â The County justifies the spraying because of nuisance mosquitoes and a finding in the âsurrounding communitiesâ of mosquitoes carrying West Nile virus (WNv). In its Facebook statement, the County […]

(Beyond Pesticides, September 1, 2020) In its new report, industry watchdog OrganicEye, a project of Beyond Pesticides, examines the rapidly expanding CBD market, uncovering numerous examples of gross violations flying under the radar. In its report, Spotting the Hackers of Hemp: The Value of Authentic Certified Organic CBD Products, OrganicEye offers examples of companies claiming organic status without going through the rigorous third-party inspection and auditing process required by federal law. As with food, organic CBD, produced from hemp/cannabis, eliminates the risks and hazards of environmentally dangerous farming practices, including the use of synthetic fertilizers, pesticides, sewage sludge, and genetically modified organisms (GMOs). Organics also shuns toxic food ingredients and food processing substances like volatile solvents. Since Congress charged USDA with protecting organic stakeholders from fraudulent practices, illegal organic marketing claims have been the most common violations reported to the agency. âIn addition to representing conventional hemp products as organic, marketers have engaged in illegal subterfuge, including creating their own âorganicâ logos because they canât use the official USDA seal and using the word âorganicâ in their brand names when the products do not qualify for organic labeling,â said Mark A. Kastel, a 30-year industry veteran and director of OrganicEye. The meteoric growth […]

(Beyond Pesticides, August 31, 2020) We don’t need to use toxic weed killers to manage unwanted vegetation in Lake Tahoe, given the havoc they will wreak on a treasured and sacred ecosystem. The Tahoe Regional Planning Agency and Lahontan Regional Water Quality Control Board (TRPA/LRWQCB) are accepting comments on a draft environmental impact report/ environmental impact statement (EIR/EIS) analyzing environmental impacts of a proposed Tahoe Keys Lagoons Aquatic Weed Control Methods Test (âProjectâ). Unless we all speak up, the Project could involve the application of herbicides to Lake Tahoe. The Action Alternative 1: Testing of Non-Herbicidal Methods Only is the environmentally best choice and should be selected for the proposed weed control test program. Protect Lake Tahoe from toxic weed killersâtake action by Sept. 3, 11:59 pm. Located on the border of California and Nevada, Lake Tahoe is treasured for its scenic and ecological values not just by residents of those states, but by many others.

(Beyond Pesticides, August 28, 2020) The Environmental Protection Agency (EPA) has granted âemergencyâ permission to the State of Texas to allow the use of SurfaceWiseÂŽ2, 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 âemergencyâ 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 Pesticidesâ 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 Pesticide, August 27, 2020) The latest research finds that pesticides and fertilizers supersede fossil fuels as the greatest contributor of sulfur emissions in the environment, according to U.S. National Science Foundation (NSF)-funded study, published in Nature Geoscience. Particularly, atmospheric sulfur dioxide and reactive sulfur emissions contribute to sulfur deposition via acidic rain and snow, causing a multitude of human and animal of health problems and environmental degradation. Although some U.S. policy regulations curb sulfur emissions from atmospheric sources, alternative sulfur inputs from agricultural sources can cause similar issues as atmospheric sulfur emissions, including acid rain. With peak sulfur concentrations from agricultural outputs up to ten-fold higher than previous 20th-century sulfur levels, studies like these are significant in understanding how underrepresented pollution sources may contribute to overall environmental pollution. Lead author of the study, Eve-Lyn Hinckley, Ph.D., states, “We have an imperative to understand the impact that we’re having on the environment. And then we need to work together towards solutions to mitigate those effects.” Sulfur is a naturally occurring element found in vast, underground deposits. Although relatively stable underground, it is highly reactive once it reaches the surface, transforming into chemical compounds, like sulfur oxides, upon exposure to oxygen. Over […]

(Beyond Pesticides, August 26, 2020) Neonicotinoid insecticides damage the health of shrimp and oysters, according to two (1, 2) new studies published by Australian researchers. Although this class of chemicals is best known for its hazardous impacts on pollinator populations, it is becoming increasingly clear that the entire food chain is at risk from continued neonicotinoid use. This study builds on an already established body of literature showing these systemic chemicals poison waterways. Researchers began by collecting samples of shrimp and oysters from growers along the coast, and acclimating the species to laboratory conditions. Both collections were separated into different test groups. Oysters where exposed in their tanks to various concentrations of the neonicotinoid imidacloprid. Shrimp were exposed to imidacloprid through two methods: in their feed, and in their tanks. Each separate test group was further separated into high and low exposures. A control group that did not receive any pesticide exposure was also established in each experiment. For the oyster populations, scientists found a range of negative effects. Imidacloprid inhibits the proper functioning of the enzyme acetylcholinesterase, a well-known impact of many pesticides that results in damage to the nervous system. Detoxification mechanisms are activated, and changes are observed […]

(Beyond Pesticides, August 25, 2020) The City of Gaithersburg, MD has chosen to opt-in to Montgomery Countyâs Healthy Lawns Act, restricting toxic pesticide use on public and private property. According to the local Patch, the mayor and City Council voted to adopt the law in mid-August, and it will take effect for all residents and businesses in city on December 1. Although Montgomery County passed the Healthy Lawns Act approximately five years ago, incorporated cities within the county are required to proactively opt-in to the law for it to apply within their jurisdiction. Gaithersburg is the latest, and largest city to opt-in to the countyâs law, which encourages organic practices by limiting pesticide use on lawns and landscapes to products that are certified organic or considered minimum risk by the U.S. Environmental Protection Agency. In mid-June, the Town of Garrett Park also opted in to the law, according to reports. Advocates are advocating that all cities within Montgomery County adopt the law. The same group of grassroots advocates that pushed Montgomery County leaders to adopt its Healthy Lawns Act years ago is also leading the push for opt-ins.
