Results from a global survey highlight widespread eco-anxiety in young people
By Roberta Attanasio The notion of “eco-anxiety” has been creeping into worldwide culture for the past few decades. Now, it’s in the mainstream vocabulary. It’s defined as worry or concern about climate change and its effects. Children and young adults are especially vulnerable to eco-anxiety, as shown by a recent study based on a survey of people aged 16 to 25. The study, published in the journal The Lancet Planetary Health (December 2021), found that nearly 60% of survey participants were very or extremely worried about climate change. A similar number said governments were not protecting them, the planet, or future generations. More than 50% reported each of the following…

The fertile top layers of soils keep disappearing, a new study shows
By Roberta Attanasio Plants grow in and out of soils—and sustain almost all living beings on our planet, either directly or indirectly. But soils are rapidly disappearing from farms all around the world, threatening our ability to grow food. The treasure beneath our feet is continuously subjected to erosion and degradation, mostly resulting from intensive farming practices. Relentless tilling, for example, allows weeds control by turning the soil over, but leaves it bare and vulnerable to wind and rain—causing the loss of the fertile top layer. Even the famed black Iowa soil is disappearing. “In Iowa they call it ‘black gold’—a fertile blanket covering the landlocked Midwestern state. Thousands…

How protecting our oceans can help solve some of the world’s greatest challenges
By Roberta Attanasio Stories of the past tell us that our oceans are deep, mysterious and indestructible—but oceans are quickly changing, bowing to biological degradation and much more. Oceans are damaged every day by oil and gas drilling, pollution, and industrial impacts. Human activities are changing the ocean’s chemistry, destroying habitats, and killing marine life. The Great Barrier Reef has lost half of its corals since 1995, and a report released in 2019 on the state of global biodiversity found that over one-third of marine mammals and nearly one-third of sharks and shark relatives are threatened with extinction. Overfishing is one of the primary threats to ocean biodiversity—it endangers not…

A new report shows the worldwide magnitude of food waste
By Roberta Attanasio The foreword of a new United Nations Environment Programme (UNEP) report starts with a poignant observation: “If food loss and waste were a country, it would be the third biggest source of greenhouse gas emissions. Food waste also burdens waste management systems, exacerbates food insecurity, making it a major contributor to the three planetary crises of climate change, nature and biodiversity loss, and pollution and waste.” The report (UNEP Food Waste Index Report 2021) was produced by the UNEP in collaboration with the partner organization WRAP, a global NGO based in the UK. It was released on March 4, 2021, and shows that substantial amounts of food…

Children exposed to air pollution are more likely to develop disease later in life
By Roberta Attanasio We have known for quite some time that the first years of life represent a unique “window of vulnerability”—exposures to environmental chemicals at this time influence cellular programming in ways that shape health and disease in later years. For example, recent research shows that there is a significant association between multiple prenatal and early life exposures to indoor pollutants and the degree of allergic sensitivity in 2-year old children. In other words, babies exposed to air pollution during prenatal life and for the first several moths after birth, up to 2 years of age, are at higher risk of developing allergic sensitivity. Now, results from a study published…

Did you hear about Science Moms?
By Roberta Attanasio All around the world, mothers are concerned about their kids’ future. What world will they live in? A world where humanity is still waging war on nature, or one at peace? Science Moms want to talk about our world and what we can do to make it a better place—they are climate scientists concerned about their kids’ future and believe that, with moms everywhere, it’s possible to build a cleaner, safer future for all kids. This is how Science Moms define themselves: “We are a group of climate scientists and mothers who care deeply about the planet that our children will inherit. Together, we aim to demystify climate…

It’s time to stop our war on nature
By Roberta Attanasio A newly released report by the United Nations Environment Programme (UNEP) provides a scientific blueprint to tackle the climate, biodiversity, and pollution emergencies—and invites the world to make peace with nature. The report. “Making peace with nature: a scientific blueprint to tackle the climate, biodiversity and pollution emergencies” (February 18, 2021), is based on evidence from global environmental assessments. It points out that humanity’s environmental challenges have continued to grow in number and severity for the past 50 years, and now represent a planetary emergency. “Humanity is waging war on nature. This is senseless and suicidal. The consequences of our recklessness are already apparent in human suffering,…

Measles outbreak in Samoa: potential effects on COVID-19
By Roberta Attanasio Measles—one of the world’s most contagious diseases—induces immune amnesia, an anomaly of the immune system that results in increased susceptibility to infections by other pathogens. Not surprisingly, there are concerns globally about populations that have recently experienced measles outbreaks. These populations could be at elevated risk of developing more severe COVID-19 illness, resulting in increased mortality. The emergence of the current COVID-19 pandemic in the first months of 2020 occurred closely after a global resurgence of measles. According to the World Health Organization (WHO), by November 2019, measles case numbers had tripled compared with the same period in the previous year. Measles spreads easily when an infected…

As coal mining declines, community mental health problems linger
By Roberta Attanasio The U.S. coal industry is in rapid decline, a shift marked not only by the bankruptcy of many mine operators in coal-rich Appalachia but also by a legacy of potential environmental and social disasters. As mines close, states, the federal government and taxpayers are left wondering about the costs of cleaning up the abandoned land, especially at mountaintop removal sites, the most destructive type of mining. As coal companies go bankrupt, this has left states concerned taxpayers may have to pick up the environmental cleanup costs. But there are also societal costs related to mountaintop removal mining’s impact on health and mental health. As an immunologist, I…

Pharmaceuticals in Drinking Water?
By Roberta Attanasio The problem of contaminated tap water in the U.S. goes well beyond Flint—and also beyond lead. There are many more toxic chemicals in our drinking water that we like to believe. Communities in New York, New Hampshire and Vermont recently found elevated levels of PFOA, a suspected carcinogen, in their water supplies. PFOA, or perfluorooctanoic acid, is a synthetic perfluoroalkyl chemical used to manufacture nonstick pan coatings and water-resistant clothing. And, even more recent is the finding that water discharged from Burlington’s wastewater treatment plant into Lake Champlain—the source of drinking water for tens of thousands of people in the Burlington area—contains concentrations of pharmaceuticals high enough to reflect…
