(Beyond Pesticides, November 30, 2020) The “environment” is central to President-elect Biden’s priorities: climate change, COVID-19, and the next pandemic, racial equity, and economic recovery. The new administration should include an EPA administrator who understands the relationships among these and other environmental issues and has a clear vision of the changes needed to dramatically change our course, currently heading for ecological destruction. Tell President-elect Biden to appoint an EPA Administrator who is an environmentalist with broad environmental credentials and a vision that embraces a dramatic transition away from hazardous chemicals and polluting practices at this perilous time. Let’s start with what the past four years has taught us about who we do NOT want as EPA Administrator. We do not want an industry lobbyist, someone whose work has been funded with industry money, who has represented industry in litigation or as a lobbyist, who has attacked environmentalists, or has never read Silent Spring. Such a person is not qualified to provide the leadership needed to address priority issues and understand the interconnections necessary to address the crises associated with climate, health, and biodiversity decline. On the other hand, a strong candidate will support holistic thinking, with an understanding of interrelationships in […]

(Beyond Pesticides, November 26, 2020) With the coronavirus pandemic raging across the United States, this Thanksgiving will be like no other in recent memory. Although many will spend dinner away from friends and family, and video calls don’t quite match time around the table, there is still so much to give thanks for. This year, we at Beyond Pesticides are honoring the essential, frontline workers that have helped us through this difficult year.   It is not enough to simply gives thanks to health care, transportation, retail, hospitality, custodial, teachers, farmworkers, landscapers, and other frontline workers putting themselves at risk. We must take action to improve their conditions – particularly when it comes to exposure to toxic chemicals that exacerbate underlying conditions and increase susceptibility to Covid-19. This 2020 Thanksgiving, give thanks but also show thanks by taking action. Give Thanks to Health Care Workers. Health care workers are past overstressed. Many are at the point of complete burnout. Already subject to multiple medical and personal demands, many health care workers continue to lack proper equipment, are understaffed, and at greatest risk of contracting Covid-19. Show Thanks: The best action to take to thank essential health care workers, oddly enough, […]

(Beyond Pesticides, November 25, 2020) New research from the Centre for Environment and Occupational Health Research at the University of Cape Town (UCT), South Africa, finds a link between pesticide exposure and adverse neurological symptoms among children and adolescents living in agricultural areas. Considering the etiology (cause) of many brain and neurological disorders are unknown, research like this is significant for understanding how pesticide exposure promotes disease development, especially among vulnerable populations. Researcher notes, “Children who indicate activities related to pesticide exposure may be at higher risk for developing headaches and lower cognitive performance in the domains of attention, memory and processing speed. […]Given [the] history and socio-economic divide to the farm laborers, […]future interventions should aim to reduce the health risks of these vulnerable populations, including their children.” The study demonstrates that there is a relationship between pesticide exposure from various farm-related and leisure activities and headaches and neurocognitive functioning (i.e., autism, attention deficit hyperactivity disorder (ADHD), lower intelligence (IQ), and harmful social behavior and behavioral regulation) in children and adolescents. To assess which farm-related/leisure activities concerning pesticide exposure cause cognitive symptoms, researchers administered a questionnaire addressing child pesticide handling, direct consumption of field crops, interaction with field adjacent water sources, […]

(Beyond Pesticides, November 24, 2020) Reinforcing a body of scientific evidence, a new study finds that eating organic food lowers one’s risk of developing type 2 diabetes. With 1 in 10 (34 million) Americans afflicted with type 2 diabetes, and 1 in 3 (88 million) with prediabetes, new strategies focused on prevention are urgently needed. The results of the study, published by a team of French and American researchers in the International Journal of Behavioral Nutrition and Physical Activity, reinforce the triple bottom line (profit, people, and the environment) benefits of organic food for public health, the environment, and the wider economy. Scientists used data from NutriNet-Santé, a massive study including over 170,000 participants (averaging 52 years old) that regularly respond to questions concerning lifestyle, dietary intake, body type, physical activity, and health status. Roughly 33,000 NutriNet-Santé participants completed food frequency questionnaire regarding how often they consumed organic food. After four years, 293 surveyed individuals had been diagnosed with type 2 diabetes. Researchers then looked at how organic food consumption affected the risk of developing the disease, adjusting for body mass index, gender, family history of diabetes, physical activity, education, economic status, occupation, smoking, and alcohol consumption. Higher organic food […]

(Beyond Pesticides, November 19, 2020) A new study by researchers at the University of California, Santa Barbara (UCSB) finds that crop diversity in commercial agriculture is just as essential to supporting a stable biological system as plant diversity on non-commercial landscapes. Furthermore, less diverse crop areas lead to higher, more intensive pesticide use, indicating a threat to environmental and human health, as well as food security. This research highlights the need to develop policies that facilitate a decrease in overall pesticide use by helping farmers and global leaders make more knowledgeable decisions about crop area size and diversity to sustain biodiversity. Researchers note, “While [crop] complexity increases stability and reduces high deviations in insecticide use, accounting for crop and farmer-specific characteristics is crucial for statistical inference and sound scientific understanding. In this study, researchers aim to understand how crop and landscape diversity impacts pest populations, using insecticide use data as a surrogate for pest populations data. Data observations are from Kern County Agricultural Commissioner (CAC), California, over the period 2005 to 2017. Crop data includes crop type, acceptable field size, field and farmer permit number, and active dates for the field. To estimate pesticide use variance, researchers summated annually and peak insecticide […]

(Beyond Pesticides, November 18, 2020) The herbicide atrazine is likely to adversely affect over half of endangered species listed in the United States, according to a report released by the U.S. Environmental Protection Agency (EPA) as part of a legal agreement with the Center for Biological Diversity (CBD). Based on both adverse human health and environmental threats, Beyond Pesticides joined with Center for Food Safety, CBD, and other public-interest groups in October to sue EPA over its decision to reapprove atrazine, an endocrine-disrupting herbicide banned across much of the world. These actions follow the agency’s recent reapproval of atrazine, which reduced a number of safeguards for public health and the environment, and it’s enactment of rules that limit endangered species reviews.  See (Lawsuit Challenges EPA Reapproval of Endocrine-Disrupting Pesticide Atrazine: Agency Slashes Protections for Children, Waterways.) Although advocates are hopeful that the next administration will shift toward an EPA that lives up to its namesake, there is considerable ground to make up. Atrazine is an herbicide that disrupts the endocrine system by mimicking the body’s natural hormones, binding to hormone receptors in the body. In humans, the effect can result in birth defects, damage to the reproductive system, and chronic […]

(Beyond Pesticides, November 17, 2020) Excessive use of nitrogen fertilizers in agriculture is driving global nitrous oxide (N2O) emissions higher than any projected scenario, putting the world at greater risk of a climate catastrophe. According to research published by an international team of scientists in the journal Nature, failure to adequately address nitrous oxide emissions has the potential to impede the ability for the world to keep warming below the 2°C target established under the Paris Climate Agreement, necessitating further cuts in other greenhouse gasses. The paper is a clarion call for greater attention to agriculture’s role in generating and mitigating the climate crisis. “The dominant driver of the increase in atmospheric nitrous oxide comes from agriculture, and the growing demand for food and feed for animals will further increase global nitrous oxide emissions,” explains study lead author Hanqin Tian,  PhD, director of the International Center for Climate and Global Change Research at Auburn University in Alabama. “There is a conflict between the way we are feeding people and stabilizing the climate.” Nitrous oxide both damages ozone and warms the atmosphere, as it is roughly 300x better at capturing heat than carbon dioxide. To account for global nitrous oxide emissions, […]

(Beyond Pesticides, November 16, 2020) Since the U.S. Department of Agriculture (USDA) sits at the nexus of complex and systemic problems that need urgent attention—pesticide-dependent genetically engineered crops, the integrity of certified organic agriculture, and the climate crisis—the choice of the agency’s head is critical to meeting the challenges necessary to sustaining life. USDA has long been a big promoter of chemical-intensive agriculture. With President-elect Joe Biden committed to priorities of addressing health care, systemic racism, and climate change, the time is now for USDA to change the way it does business. We need an organic advocate in the Secretary of Agriculture, who must be committed to transitioning chemical-intensive agriculture to organic practices—thereby eliminating petroleum-based pesticides and synthetic fertilizers, sequestering atmospheric carbon, protecting farmworker and farmer health, delivering a safe food supply, and ensuring clean air, water, and healthy terrestrial and aquatic ecosystems. Tell President-elect Biden to appoint an organic leader as USDA Secretary. The purview of USDA is far-ranging—from SNAP (food stamps) to agricultural support programs to research to inspections and other regulations. And the National Organic Program. Research includes programs promoting pesticides and genetically engineered crops. USDA’s history with President-elect Biden’s priority issues has not been good historically. […]

(Beyond Pesticides, November 11, 2020) Neonicotinoid insecticides inhibit honey bee sleep cycles, leading to stress and population declines, according to research from Vanderbilt University, published in Scientific Reports. Although there is already ample evidence of the dangers these systemic insecticides pose to pollinators – as evidenced by recent bans in the European Union and Canada – this new line of investigation add further detail to the ongoing crisis in the pollinator world. “I was thinking about honey bee disappearances and it clicked—if pesticides are killing bees indirectly but we don’t know exactly how, maybe it’s because they’re getting physically lost,” said study coauthor Michael Tackenberg, PhD.  Scientists conducted the experiment using honey bees located on Vanderbilt’s campus, which does not use neonicotinoid insecticides. After returning from pollen collection, forager bees were captured at their hive entrance and moved into monitoring tubes, which were subsequently transferred to the lab. In the lab, scientists were able to control light and dark cycles, and exposed bees to levels neonicotinoids they would likely experience if foraging on contaminated flowers. Foraging bees were first exposed to light/dark at 12/12 cycles, followed by four days of complete darkness, at which time some bees were provided neonics, […]

(Beyond Pesticides, November 10, 2020) Higher rates of plant diversity can limit pest pressure and reduce the need for pesticide use, finds a new study published by the German Centre for Integrative Biodiversity Research. With rampant declines in insect biodiversity from the ongoing insect apocalypse, it is critical that farmers and ecologists better understand the natural interplay between plants and insects, and the important ecosystem services that flow from these interactions. “Our experiments show that conserving plant diversity provides multiple benefits for controlling herbivore pests, which could play a key role in reducing inputs of agrochemicals and enhancing plant productivity,” said study coauthor Andrew Barnes, PhD. Scientists investigated the importance of plant biodiversity through study of two ongoing biodiversity experiments. One known as the The Jena Experiment, based in Central Europe, and another, the Cedar Creek Biodiversity Experiment, in the state of Minnesota. Both sites established blocks of plant diversity gradients, flowing from monoculture plots to those with 16 species or more. Researchers aimed to investigate how insect food webs and feeding behavior, plant biomass, and pest predator response changes as a function of plant biodiversity. Results showed that higher plant diversity resulted in an insect (herbivore pest) feeding rate […]

(Beyond Pesticides, November 9, 2020) Now that we have learned what a pandemic looks and feels like, with the astounding levels of infection, hospitalization, and death from COVID-19, we must take serious steps to prevent another pandemic on the horizon—this one tied to bacterial resistance to antibiotics. An important article in The Lancet points to a “looming potential pandemic” resulting from a “rise in multidrug-resistant bacterial infections that are undetected, underdiagnosed, and increasingly untreatable, [which] threatens the health of people in the USA and globally.” Tell your Congressional Representative and Senators it is urgent that the National Action Plan for Combating Antibiotic-Resistant Bacteria be initiated. Two contributors to antimicrobial resistance (AMR) that are being highlighted are in agriculture and use of antibiotics in medicine when not warranted. The misuse of antibiotics in agriculture includes antibiotics used to control certain bacterial diseases in plant agriculture (especially oxytetracycline and streptomycin). While crop uses are important contributors to breeding bacterial resistance, they are small compared to their uses in livestock production. Antibiotics are used largely as additives to animal feed to ward off any potential infections and to promote unnaturally rapid growth (the latter of which translates to higher profits), rather than being used […]

(Beyond Pesticides, November 6, 2020) Beyond Pesticides joined health and environmental groups suing the U.S. Environmental Protection Agency (EPA) late last month over its decision to reapprove the endocrine disrupting herbicide atrazine with fewer protections for children’s health. Despite the chemical being banned across much of the world, EPA continues to make decisions that benefit chemical industry executives. “EPA’s failure to remove atrazine represents a dramatic failure of a federal agency charged with safeguarding the health of people, wildlife, and the environment,” said Jay Feldman, executive director of Beyond Pesticides. “We seek to uphold the agency’s duty to act on the science, in the face of viable alternatives to this highly toxic weedkiller.” It is not hyperbole, but in fact scientifically documented, that atrazine exposure “chemically castrates” frogs, impairs fish reproduction, and can result in birth defects and cancer in humans. EPA decision comes on the heels of a rash of industry-friendly decisions. Within the last month, the agency has finalized rules weakening farmworker buffer zone protections, reapproving dicamba use on genetically engineered crops, and reregistering some of the most toxic pesticides on the market. The lawsuit, filed in the Ninth Circuit Court of Appeals, contends that before reapproving atrazine, […]

(Beyond Pesticides, November 5, 2020) Research at the University of California San Francisco (UCSF) finds that pesticide exposure increases the risk of developing Parkinson’s disease (PD), regardless of whether disease onset is idiopathic (spontaneous) or genetic (GBA genetic risk variant). Although the exact etiology of PD remains unknown, epidemiological and toxicological research repeatedly identifies exposure to pesticides, as well as specific gene-pesticide interactions, as significant adverse risk factors that contribute to PD. Furthermore, this study, “Gene Variants May Affect PD Risk After Pesticide Exposure,” suggests that environmental triggers like occupational exposure to pesticides can prompt PD in individuals with or without the genetic precursor. This research demonstrates the importance of assessing disease etiology concerning occupational pesticide exposure, especially if disease triggers are overwhelmingly non-hereditary. Since not all individuals genetically predisposed to the disease develop PD, with only 10 to 15 percent of PD cases being genetic, government officials need to consider alternate etiological pathways that include environmental risk factors. Study researchers note, “‘Environmental exposures may have differential effects in different genotypes’ and may predispose people with PD to different symptom burden.”  Parkinson’s disease is the second most common neurodegenerative disease, with at least one million Americans living with PD and about […]

(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 30, 2020) The European Union (EU) adopted, in mid-October, a new strategy on chemicals — including pesticides — that seeks to deal with their combined (synergistic) and cumulative impacts on human and environmental health. A highlight of the new strategy is the acceleration of work, already begun across the EU, to address the “chemical cocktail” impacts of pesticides and other chemicals. Human exposures to such “cocktails” can happen through use of multiple different agricultural pesticides that can persist as residues on food, and via industrial processes and consumer products. Beyond Pesticides has insisted for years that, here in the states, the Environmental Protection Agency (EPA) has been way behind the eight ball in dealing with the potential synergistic and cumulative impacts of the pesticides its registers for use. Advocates have argued that the agency must be far more rigorous in evaluating impacts of exposures to multiple pesticides, as well as cumulative impacts. The toxicity problem the EU seeks to address is that interacting chemicals can have synergistic effects, even at very low levels — effects greater than and/or different from the expected impacts of each chemical per se. Pesticides can also have cumulative “toxic loading” effects in both […]

(Beyond Pesticides, October 29, 2020) Natural areas around farmlands play an important role in managing pest outbreaks and therefore reducing insecticide use, a new study published in the journal Ecology Letters finds. While industrial agriculture puts pressure on farmers to grow single crops on ever larger farms to achieve economies of scale, these monoculture landscapes have significant downsides for public health and the environment. “Overall, our results suggest that simplified landscapes increase vineyard pest outbreaks and escalate insecticide spray frequencies,” said lead author Daniel Paredes, PhD, to the Daily Democrat. “In contrast, vineyards surrounded by more productive habitats and more shrubland area are less likely to apply insecticides.” To investigate the effect of nearby landscapes on farm pest pressure, the team of University of California, Davis scientists used a database created by the government of Spain. For 13 years, the government monitored 400 Spanish vineyards for the presence of the European Grapevine Moth. The moth is a notorious vineyard pest (discovered in California vineyards in 2009), laying three generations of eggs on grapes. In the first generation, the moth larvae will web and feed on flowers. In the second and third, they feed on berries, damaging harvests. Scientists developed a […]

(Beyond Pesticides, October 27, 2020) The insecticide fipronil is more toxic to aquatic insects than previously thought, often present in U.S. waterways, and can trigger trophic cascades that disrupt entire aquatic ecosystems, finds new research published by the U.S. Geological  Survey (USGS). The data have important implications for waterways throughout the country, but particularly in the Southeast U.S. where the chemical was found at hazardous levels in over half of sampled steams. Despite the high quality of the findings by a U.S. government agency, pesticide regulators at the U.S. Environmental Protection Agency (EPA) do not adequately consider ecosystem-level effects when determining whether to register a pesticide. As a result, without public pressure on the agency, it is unlikely it will follow the science and take the action necessary to rein in use and safeguard the environment. Fipronil is a systemic pesticide that can travel through plant tissues and be expressed in its pollen, nectar, and dew droplets. Due to its systemic properties and similar toxicity profile, it is often targeted for restriction alongside the notorious neonicotinoid class of insecticides. Although fipronil is equally concerning, there is less data on the range of harm the chemical may cause. To better understand […]

(Beyond Pesticides, October 23, 2020) In central California, what promises to be a landmark series of lawsuits against Corteva (formerly DowAgroSciences), maker of the pesticide chlorpyrifos, is under way, spearheaded by the case Alba Luz Calderon de Cerda and Rafael Cerda Martinez v. Corteva Inc., et al. This first suit, brought by the parents of Rafael Cerda Calderon, Jr. on his behalf, charges that his lifelong disabilities were caused by chronic exposures to chlorpyrifos. The parents are suing for general damages, compensatory damages (due to Rafael, Jr.’s loss of earning capacity), medical care costs, and “punitive damages for the willful, reckless, and recklessly indifferent conduct of the Defendants” in intentionally hiding the dangers of their chlorpyrifos products from customers and the public. As with so many dangerous pesticides, absent effective federal regulation, states, cities, and other entities are taking action to protect people from this compound, and as in this case, individuals are seeking redress for harms suffered. Beyond Pesticides has long advocated for a ban on the use of chlorpyrifos because of the grave risks it poses. The case was filed in mid-September in California Superior Court, Kings County, and names not only Corteva, but also, the cities of Huron and Avenal, Woolf […]

(Beyond Pesticides, October 22, 2020) Prolonged dermal (skin) exposure to hazardous disinfectants, via handling and/or residue on surfaces, can induce the risk of adverse skin reactions (i.e., inflammation, burns, necrosis), according to a novel review analysis published in Clinics in Dermatology. Researchers of the review, “Dermatologic reactions to disinfectant use during the COVID-19 pandemic,” examine skin reactions associated with dermal exposure to various disinfectants approved for use against COVID-19 by the European Chemical Agency (ECA) and the U.S. Environmental Protection Agency (EPA). The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) classifies disinfectants as pesticides, so it is up to the states to delegate training, registration, and enforcement. Many states enforce pesticide training that allows professional applicators to learn how to handle, apply, and store pesticides properly. However, many of these same states do not have professional training for disinfectant use, especially wide-scale applications. Consequently, disinfectant applications are now more pervasive than ever, especially as school reopenings ensues. Considering failure to “Comply with Labeling and Permit Conditions” was the most common pesticide use violation of 2018, according to the California Department of Pesticide Regulations (DPR), advocates are urging global leaders to recognize the potential impacts that frivolous disinfectant use can have on […]

(Beyond Pesticides, October 21, 2020) Women now account for one in four agricultural jobs in the United States, and these important workers face unique challenges to their health and well-being, as outlined by a report published by Boise State University scientists. Farmworkers, often immigrants, or from communities of color, are frequently referred to as ‘invisible’, despite the essential job they perform getting food to American’s dinner tables. With their struggle and plight outside of the view of mainstream news, it is critical that U.S, residents better understand the lives they lead, and their daily obstacles, to inform how their conditions can be improved. “In this study, we tried to understand the women that we were working with what their concerns were and what their challenges were rather than coming in and just saying what we thought the concerns were,” Cynthia Curl, PhD, Associate Professor at Boise State University, told Idaho News 6 (IN6). To better assess the well-being of women farmworkers, researchers conducted mixed method data collection, through surveys, focus groups, and urinary analysis for pesticide body burden. Surveys were received from 70 Latina farmworkers, with 22 participating in focus groups and 11 in semi-structured interviews. An assessment of pesticide […]

(Beyond Pesticides, October 20, 2020) The additive stress of pesticide exposure and food scarcity leads to significant declines in wild pollinator populations, according to research published by scientists at University of California, Davis. Although it is well known that insect and pollinators populations are at risk from multiple stressors related to industrial agriculture, comprehensive evaluations are a challenging scientific undertaking. “Just like humans, bees don’t face one single stress or threat,” said lead author Clara Stuligross, a PhD. candidate in ecology at UC Davis. “Understanding how multiple stressors interplay is really important, especially for bee populations in agricultural systems, where wild bees are commonly exposed to pesticides and food can be scarce.” To better understand the interplay between these two stressors, researchers designed a field study. Mason bee pollinators were provided cages to nest in, and each stressor was separated out. One set of bees were provided high levels of food availability, while another received scant floral resources. Certain cages within each food level were treated with the product Admire Pro, a Bayer Cropscience insecticide containing the neonicotinoid imidacloprid. Scientists found significant impacts on the factors that deal with mason bees’ reproductive success. This includes the likelihood that a female […]

(Beyond Pesticides, October 16, 2020) The Lancet has published an article that identifies several of the multiple and interacting crises the U.S. and world face, with a focus on another “looming potential pandemic . . . [a] rise in multidrug-resistant bacterial infections that are undetected, undiagnosed, and increasingly untreatable, [whose rise] threatens the health of people in the USA and globally.” It calls on leaders in the U.S. and beyond, asking that even as they address the current coronavirus pandemic, they also attend to the antimicrobial resistance (AMR) problem, which is a growing threat to public health. The co-authors outline a number of strategies for progress on AMR, including banning of medically important antibiotics in agribusiness, and promoting consumer, and supplier and private sector, awareness and action on food choices. Beyond Pesticides endorses these strategies, but insists that a genuine solution would include the transition to organic agriculture, not least for the health benefits it would provide. The introduction to the article adds another crisis layer — the climate emergency — and asserts that any resolutions of these crises will, or will not, unfold in a political context: “The outcome of the U.S. election will have far-reaching consequences for planetary […]

(Beyond Pesticides, October 15, 2020) A review of scientific literature on the correlation between respiratory diseases and pesticides exposure—published in the journal Annals of Agricultural and Environmental Medicine (AAEM), “Influence of pesticides on respiratory pathology—a literature review”—finds that exposure to pesticides increases incidents of respiratory pathologies (i.e., asthma, lung cancer, and chronic obstructive pulmonary disease [COPD]—or chronic bronchitis). The review by researchers at the Iuliu Hatieganu’ University of Medicine and Pharmacy Cluj-Napoca, Cluj-Napoca, Romania, looks at how pesticide exposure adversely propagates and reinforces respiratory diseases in humans. This review highlights the significance of evaluating how pesticide exposure impacts respiratory function, especially since contact with pesticides can happen at any point in the production, transportation preparation, or application treatment process. Researchers in the study note, “Knowing and recognizing these respiratory health problems of farmers and their families, and also of [pesticide] manipulators/retailers, are essential for early diagnosis, appropriate treatment, and preventive measures.” This study results are critically important at a time when exposure to respiratory toxicants increases vulnerability to Covid-19, which attacks the respiratory system, among other organic systems. The respiratory system is essential to human survival, regulating gas exchange (oxygen-carbon dioxide) in the body to balance acid and base tissue cells for normal […]
