EPA plans to ignore thousands of deaths by changing its methods of risk assessment

EPA plans to ignore thousands of deaths by changing its methods of risk assessment

Comments 0 Comment

The New York Times reports: The Environmental Protection Agency plans to change the way it calculates the future health risks of air pollution, a shift that would predict thousands of fewer deaths and would help justify the planned rollback of a key climate change measure, according to five people with knowledge of the agency’s plans. The proposed change would dramatically reduce the 1,400 additional premature deaths per year that the E.P.A. had initially forecast as a result of eliminating the…

Air pollution is deadlier than tobacco smoking

The Guardian reports: Air pollution may be damaging every organ and virtually every cell in the human body, according to a comprehensive new global review. The research shows head-to-toe harm, from heart and lung disease to diabetes and dementia, and from liver problems and bladder cancer to brittle bones and damaged skin. Fertility, foetuses and children are also affected by toxic air, the review found. The systemic damage is the result of pollutants causing inflammation that then floods through the…

Deregulation and climate change result in growing number of Americans breathing polluted air

Deregulation and climate change result in growing number of Americans breathing polluted air

Comments 0 Comment

CNN reports: More Americans are breathing air that will make them sick, according to the American Lung Association’s annual State of the Air report. The country had been making progress in cleaning up air pollution, but during the Trump administration, it has been backsliding, the report says. Deregulation and climate change are largely to blame. President Donald Trump made a pledge in his 2017 State of the Union address to “promote clean air and water,” but his administration has reversed…

We need contact with nature for the sake of our sanity

We need contact with nature for the sake of our sanity

Jonathan Lambert writes: The experience of natural spaces, brimming with greenish light, the smells of soil and the quiet fluttering of leaves in the breeze can calm our frenetic modern lives. It’s as though our very cells can exhale when surrounded by nature, relaxing our bodies and minds. Some people seek to maximize the purported therapeutic effects of contact with the unbuilt environment by embarking on sessions of forest bathing, slowing down and becoming mindfully immersed in nature. But in…

On a continent wracked with epidemics, millions turn to traditional healers

On a continent wracked with epidemics, millions turn to traditional healers

Comments 0 Comment

The New York Times reports: Across the African continent, according to the World Health Organization, there are about 80 times as many traditional healers as there are medical doctors. Millions of Africans consult healers but, studies suggest, usually do not admit it if they see doctors, too. In Congo, doctors now fighting Ebola believe that many of their patients first get infected while visiting such healers. They may arrive at the home of someone like Mr. Muriisa [who the reporter…

Bloomberg reports: There’s more to life than money, and economists know it. As new assessments of global living standards proliferate, attempting to gauge how healthy, happy and successful humans are depending on where they live, a pattern is slowly emerging. While slight variations in data can throw up different winners, smaller countries are increasingly dominating the top of the lists while big countries with booming economies fall behind. A new analysis, the Global Wellness Index published by investment firm LetterOne,…

Evidence mounts that gut bacteria can influence mood, prevent depression

Evidence mounts that gut bacteria can influence mood, prevent depression

Science magazine reports: Of all the many ways the teeming ecosystem of microbes in a person’s gut and other tissues might affect health, its potential influences on the brain may be the most provocative. Now, a study of two large groups of Europeans has found several species of gut bacteria are missing in people with depression. The researchers can’t say whether the absence is a cause or an effect of the illness, but they showed that many gut bacteria could…

OxyContin maker explored expansion into ‘attractive’ anti-addiction market

Comments 0 Comment

By David Armstrong, ProPublica, January 30, 2019 Not content with billions of dollars in profits from the potent painkiller OxyContin, its maker explored expanding into an “attractive market” fueled by the drug’s popularity — treatment of opioid addiction, according to previously secret passages in a court document filed by the state of Massachusetts. In internal correspondence beginning in 2014, Purdue Pharma executives discussed how the sale of opioids and the treatment of opioid addiction are “naturally linked” and that the…

Screen time has stunted the development of generations of children

Comments 0 Comment

The Guardian reports: A study has linked high levels of screen time with delayed development in children, reigniting the row over the extent to which parents should limit how long their offspring spend with electronic devices. Researchers in Canada say children who spent more time with screens at two years of age did worse on tests of development at age three than children who had spent little time with devices. A similar result was found when children’s screen time at…

In hunter-gatherer societies, excellent metabolic health is sustained by very active ways of living and a wide range of diets

Comments 0 Comment

The New York Times reports: Nutrition experts have long debated whether there is an optimal diet that humans evolved to eat. But a study published this month adds a twist. It found that there is likely no single natural diet that is best for human health. The research, published in the journal Obesity Reviews, looked at the diets, habits and physical activity levels of hundreds of modern hunter-gatherer groups and small-scale societies, whose lifestyles are similar to those of ancient…

New plant-focused diet would ‘transform’ planet’s future

Comments 0 Comment

The Guardian reports: The first science-based diet that tackles both the poor food eaten by billions of people and averts global environmental catastrophe has been devised. It requires huge cuts in red meat-eating in western countries and radical changes across the world. The “planetary health diet” was created by an international commission seeking to draw up guidelines that provide nutritious food to the world’s fast-growing population. At the same time, the diet addresses the major role of farming – especially…

How Trump is poisoning America

How Trump is poisoning America

The New York Times reports: Had Donald J. Trump not won the presidency in 2016, millions of pounds of chlorpyrifos most likely would not have been applied to American crops over the past 21 months. It would not have sickened substantial numbers of farm workers, or risked what the Environmental Protection Agency’s own studies suggest could be continued long-term health problems for others exposed to the chemical at low levels. Widespread concerns about chlorpyrifos led to its removal for nearly…

The Washington Post reports: Life expectancy in the United States declined again in 2017, the government said Thursday in a bleak series of reports that showed a nation still in the grip of escalating drug and suicide crises. The data continued the longest sustained decline in expected life span at birth in a century, an appalling performance not seen in the United States since 1915 through 1918. That four-year period included World War I and a flu pandemic that killed…

An image from the International Space Station captures plumes of smoke from California wildfires on August 4, 2018. NASA Richard E. Peltier, University of Massachusetts Amherst The impacts of recent forest fires in California reach well beyond the burned areas. Smoke from the Camp Fire created hazardous air quality conditions in San Francisco, more than 170 miles to the southwest – but it didn’t stop there. Cross-country winds carried it across the United States, creating hazy conditions in locations as…

William Foster writes: Rob Dunn invites us on a safari in pursuit of the wildlife teeming on our bodies and in every corner of our homes. For him, the creatures that sprawl in the human navel and under the bathroom shower head elicit the kind of wonder most of us would feel only on seeing the denizens of Tanzania’s Ngorongoro Crater or the Great Barrier Reef off Australia. Dunn is more than an informed and entertaining commentator, a David Attenborough…
