Losing nature impacts Black, Hispanic, and low-income Americans most

Pioneering study shows loss of nature will exacerbate racial and income inequality

2021-06-10
(Press-News.org) When nature vanishes, people of color and low-income Americans disproportionally lose critical environmental and health benefits--including air quality, crop productivity and natural disease control--a new study in Nature Communications finds.

The University of Vermont research is the first national study to explore the unequal impacts on American society--by race, income and other demographics--of projected declines in nature, and its many benefits, across the United States.

Focusing on three vital ecosystem services--air quality, crop pollination, and control of insect-borne disease (West Nile virus), researchers project that these benefits of nature will decrease for non-white people by an average of 224%, 118% and 111% between 2020 and 2100.

Researchers used advanced modeling to calculate changes in the distribution of these benefits by race, income levels, and population density (rural, urban, suburban).

"Given current and historical inequality in this country, our goal was to identify how future losses of nature might affect these racial and income disparities," says UVM researcher Jesse Gourevitch. "Unfortunately, we find that, in general, non-white, lower-income, and urban populations disproportionately bear the burden of declines in ecosystem benefits."

Opposing trends

Experts agree that in the future, urban populations are expected to grow, while rural populations shrink, and demographic groups become more segregated. Declines in nature will be largely driven by the conversion of forests and wetlands to cropland and urban development.

According to the study, land-use conversion trends are likely to be stronger in counties where marginalized populations are expected to grow. As a result, people of color are predicted to lose nature's benefits, while white communities are projected to see gains. Black and Hispanic people are expected to experience a substantial loss of benefits, in particular.

Among income groups, counties with the lowest per capita income are expected to experience the greatest losses in air quality and West Nile virus protection--while these benefits increase significantly in high income counties.

"By paying attention to race and income--which are often overlooked in environmental research--we can help leaders address inequities in their policy decisions, so that nature's benefits are distributed more equitably in the future," says UVM Prof. Taylor Ricketts, a global expert on measuring nature's benefits.

Troubling mismatches

Geographically, the study predicts significant "mismatches" between ecosystems benefits and human needs. For example, the team finds major declines in air quality and disease controls in urban counties where populations are expected to grow. Similarly, the researchers find steep declines in crop pollination--which is vital for farming--in rural areas, where agricultural productivity is most essential.

Beyond simply highlighting social and environmental problems, researchers say that targeted land use policies that factor in equity are needed to avoid exacerbating inequality in the U.S. These findings could also help to facilitate compensation for losses of nature's benefits among marginalized groups, they say.

"To be clear, these results don't imply that the U.S. is moving from an equitable baseline to an inequitable future," says UVM co-author Luz de Wit. "Today's inequities underpin the future disparities we estimate. For instance, Black and Hispanic people are currently disproportionately exposed to air pollution. That disparity, and others, are only expected to worsen in the future, without action."

The study was led by an international UVM team of researchers--representing Mexico, Colombia and the U.S., including Puerto Rico. Co-authors include: Jesse D. Gourevitch, Aura M. Alonso-Rodríguez, Natalia Aristizábal, Luz A. de Wit, Eva Kinnebrew, Caitlin E. Littlefield, Maya Moore, Charles C. Nicholson, Aaron J. Schwartz, and Taylor H. Ricketts.

Can you imagine one day using a telescope as thin as a sheet of paper, or a much smaller and lighter high-performance camera? Or no longer having that camera bump behind your smartphone? In a paper published in Nature Communications, researchers from the University of Ottawa have proposed a new optical element that could turn these ideas into reality by dramatically miniaturizing optical devices, potentially impacting many of the applications in our lives. To learn more about this project, we talked to lead author Dr. Orad Reshef, a senior postdoctoral fellow in the Robert Boyd Group, and research lead Dr. Jeff Lundeen, who is the Canada Research Chair in Quantum Photonics, Associate Professor in the ...

Drug commonly used as antidepressant helps fight cancer in mice

Drug commonly used as antidepressant helps fight cancer in mice
2021-06-10
A class of drug called monoamine oxidase inhibitors is commonly prescribed to treat depression; the medications work by boosting levels of serotonin, the brain's "happiness hormone." A new study by UCLA researchers suggests that those drugs, commonly known as MAOIs, might have another health benefit: helping the immune system attack cancer. Their findings are reported in two papers, which are published in the journals Science Immunology and Nature Communications. "MAOIs had not been linked to the immune system's response to cancer before," said Lili Yang, senior author of the study and a member of the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA. "What's especially exciting is that this is a very well-studied and ...

Beyond Remission: From Alcohol Dependence to Optimal Mental Health

2021-06-10
UNIVERSITY OF TORONTO & CARLETON UNIVERSITY New research published online in the journal Substance Use & Misuse is good news for those struggling with alcohol dependence: the possibility of ending this dependency gets easier with age. Moreover, more than half of individuals who have been dependent on alcohol are free of any addictions or mental illness, and nearly 40% are in excellent mental health. Using data drawn from Statistics Canada's Canadian Community Health Survey-Mental Health, researchers examined a nationally representative sample of 820 adult Canadians with a history of alcohol dependence to 19,945 who had never been addicted to alcohol. They found that in the past year, 71% of ...

Alcohol companies earned billions from underage drinking in 2016

Alcohol companies earned billions from underage drinking in 2016
2021-06-10
PISCATAWAY, NJ - Underage youth consumed $17.5 billion worth, or 8.6 percent, of the alcoholic drinks sold in 2016. Products from three alcohol companies--AB Inbev, MillerCoors and Diageo--accounted for nearly half of youth consumption, according to a new study published in the Journal of Studies on Alcohol and Drugs. Data collected in a landmark study of youth alcohol consumption by brand enabled the authors to calculate the first estimate in nearly 20 years of the monetary value of youth alcohol consumption. And for the first time, they were able to attribute those revenues to specific companies. "The alcohol industry has said they don't want minors to drink, ...

Monoclonal antibody therapy for COVID-19 safe, effective for transplant patients

2021-06-10
ROCHESTER, Minn. -- Treating transplant patients with mild to moderate cases of COVID-19 with monoclonal antibodies is safe and helps prevent serious illness, according to a Mayo Clinic study recently published in Open Forum Infectious Diseases. These results are especially important because transplant patients who are infected with COVID-19 have a higher risk of severe illness and death. "Monoclonal antibody therapy is really important for the transplant population because they are less likely to develop their own immunity. Providing them with these antibodies helps them recover from COVID-19," says Raymund Razonable, M.D., a Mayo Clinic infectious diseases specialist and the study's senior ...

New dipping solution turns the whole fish into valuable food

2021-06-10
When herring are filleted, more than half their weight becomes a low-value 'side stream' that never reaches our plates - despite being rich in protein and healthy omega-3 fatty acids. Now, scientists from Chalmers University of Technology, Sweden, have developed a special dipping solution, with ingredients including rosemary extract and citric acid, which can significantly extend the side streams' shelf life, and increase the opportunities to use them as food. Techniques for upgrading these side-streams to food products such as minces, protein isolates, hydrolysates and oils are already available today, and offer the chance to reduce the current practices of using them for animal feed, ...

Molecular changes in white blood cells can help diagnose 'the bends' earlier in divers

2021-06-10
For over a century, researchers have known about "the bends", a serious condition affecting scuba divers. However, we still know relatively little about its physiological basis. Doctors do not yet have a definitive test for the bends, instead relying on symptoms to diagnose it. A new study in Frontiers in Physiology is the first to investigate genetic changes in divers with this condition, finding that genes involved in inflammation and white blood cell activity are upregulated. The findings cast light on the processes underlying the bends, and may lead to biomarkers that will help doctors to diagnose the condition more precisely. The bends, more formally known as decompression sickness, is a potentially lethal condition that can affect divers. Symptoms ...

Patient-provider discussions about bariatric surgery play pivotal role in weight loss outcomes

2021-06-10
BOSTON -- Obesity increases one's risk for many diseases and often prevents patients from receiving other necessary medical procedures. One of the most effective ways for patients with severe obesity to lose weight is through bariatric surgery, but it's not clear how often this option is raised. In a new study published in Obesity, investigators from Brigham and Women's Hospital find that eligible patients who discuss bariatric surgery options with their primary care providers or specialists from disciplines ranging from cardiology to urology are more likely to undergo surgery and lose more weight than ...

Flickering screens may help children with reading and writing difficulties
2021-06-10
Previous studies have shown that children with attention difficulties and/or ADHD solve cognitive tasks better when they are exposed to auditory white noise. However, this is the first time that such a link has been demonstrated between visual white noise and cognitive abilities such as memory, reading and non-word decoding in children with reading and writing difficulties. "The white noise to which we exposed the children, also called visual pixel noise, can be compared with giving children glasses. The effect on reading and memory was immediate," explains Göran Söderlund, Senior Lecturer in Education at the University of Gothenburg and Professor of Special Education at the Western Norway University ...
