Collaborative for Health and Environment

For , we are celebrating three individuals who are dedicated to protecting the health and safety of their communities and the environment.

From leading Indigenous movements to speaking out about the harmful impacts of chemical exposure and mining among Indigenous communities, Tom BK Goldtooth, Fern Ānuenue Holland, and Jasmine Monroe strive to educate decisionmakers and the broader public about the rights of Indigenous peoples, and work to protect the health and well-being of their communities and future generations.

“As Indigenous Peoples, we have an understanding of our responsibilities and our role. We understand how we are here as the guardians and caretakers of the soil, land, nature, and life itself. So we want the world to have a better understanding of how to address climate change and some of the ecological challenges that this planet is now having.”

🔎 Did you know 70% of Americans have encountered false or misleading news online, and around 80% of misinformation on social media is spread by a small number of users?

Misinformation and disinformation have been increasing at an alarming rate. This is particularly important in the realm of environmental health, as it can impact how individuals make decisions that impact their own and their family's health.

In this new series, ACAT and CHE will provide tips on how to tackle mis- and disinformation and take action to protect yourself and loved ones.

📲Remember: Stay informed, know when to disengage, leverage trusted sources that rely on scientific evidence, and help your loved ones do the same.

November is Native American Heritage Month 🌎🌱

This month, we want to spotlight the work of our CHE-Alaska partner, Alaska Community Action on Toxics (ACAT), founded by Pamela Miller in 1997. ACAT was formed to support individuals throughout Alaska working against chemical contamination and for healthy communities. This includes Annie Alowa, a Yupik elder who worked for decades to press the military to clean up its toxic legacy on St. Lawrence Island (traditionally known as Sivuqaq).

Coordinated by ACAT, CHE Alaska works to inform health professionals, researchers, health-affected groups, government agents, and other concerned citizens about environmental links to disease and disability. They focus particularly on impacts of chemicals and climate change in the Arctic, which directly affect Indigenous communities in the region — and also have global implications.

NEW GUEST COMMENTARY: Reconsidering children’s health policy

Dr. Ken Geiser, Professor Emeritus at the University of Massachusetts Lowell, shares highlights from a recent paper, “Manufactured Chemicals and Children’s Health — The Need for New Law” published in the New England Journal of Medicine.

“There is a crisis in children’s health in the United States . . . A precautious children’s health policy would strive to reduce or eliminate the use of hazardous chemicals across the economy.”

Today is Children’s Environmental Health Day!

Did you know? An estimated 34% of children's chronic illnesses and developmental challenges are caused by environmental factors - and these impacts are not distributed equally. Environmental hazards are disproportionately concentrated among communities of color due to policies like redlining. These harms disproportionately affect children in lower-income families as well as Black, Latino/a, Indigenous, and other children of color. Improving our children’s health depends on righting these environmental injustices. Together, we can build a healthier, safer, more equitable future for all children. Join us for Children’s Environmental Health Day this Thursday: cehday.org

¿Sabías? Se estima que el 34% de las enfermedades crónicas y los problemas de desarrollo de los niños son causados por factores ambientales. Estos impactos no se distribuyen por igual. Los peligros ambientales se concentran desproporcionadamente entre las comunidades de color debido a políticas como la línea roja. Estos daños afectan de manera desproporcionada a los niños de familias de bajos ingresos, así como a los niños negros, latinos, indígenas y otros niños de color. Mejorar la salud de nuestros niños depende de corregir estas injusticias ambientales. Juntos, podemos construir un futuro más saludable, más seguro y más equitativo para todos los niños.

NEW GUEST COMMENTARY BLOG: The psychological toll of climate disasters

Note: This post contains distressing content

This year marks the 20th anniversary of Hurricane Katrina, and climate change continues to show itself in a myriad of ways. A growing number of individuals experience ‘eco-anxiety,’ a form of anxiety, distress, or grief associated with awareness of potential environmental degradation.

Roya Abedi, a medical student at Georgetown University School of Medicine, explores the rising rates and disproportionate impacts of eco-anxiety and the effects of climate disasters on mental health.

“Engaging in the community is a tool to gain back control of our green spaces and mental health, and the time is now to act to make eco-anxiety a word of the past.”

Did you know one study found that humans inhale as many as 68,000 microplastic particles daily?

Recently, The Guardian released an article highlighting findings from a new peer-reviewed research in the Plos One journal. The study estimates that humans can inhale as many as 68,000 microplastics daily, ranging from exposure in our home environments to our cars.

“We were quite surprised about the microplastic levels we found – it was much higher than previously estimated. . . The size of the particle is small and well-known to transfer into tissue, which is dangerous because it can enter into the bloodstream and go deep into the respiratory system.”
