As a parent and researcher, I am seeing an alarming trend. Children born just five years ago are expected to face between two- and seven-fold more extreme climate events, such as heatwaves, than their parents or grandparents. Unlike past generations, today’s young people are inheriting not only the planet as we left it but also a mounting burden of climate stressors that can shape their lifelong health and future.

It’s not rocket science that children deserve clean air to breathe, safe water to drink, nourishing food to eat, and communities that protect — not threaten — their developing bodies and brains. Yet new findings from the Children’s Environmental Health Network’s Alaska Profile for Children’s Environmental Health make one thing painfully clear: In Alaska, children face environmental risks significantly above the national average, and the consequences are profound.

A snapshot of risk: The story the indicators tell

Children’s Environmental Health Indicators, or CEHIs, help us understand three things: environmental hazards, children’s exposure to those hazards and the health outcomes that follow. For Alaska, the data should spark urgent action.

• Alaskan children are more likely to face unsafe drinking water.

In 2023, 43.6% of Alaska’s public water utilities had drinking water violations far higher than the U.S. national rate of 27.6%. Clean water should never depend on geography.

• Toxic releases are massive.

In 2023, Alaska industries disposed of or released 899 million pounds of toxic chemicals a staggering number, even when compared with the U.S. total of 3.3 billion pounds. Many of these chemicals, such as mercury, arsenic and lead, are known developmental and neurological toxicants.

• Children’s bodies are showing the consequences.

Between 2017 and 2021, 2% to 4.7% of Alaska children under age 6 who were tested had blood lead levels at or above the level the CDC considers elevated, compared with 1.3% nationwide. Because many at-risk children are never tested, this is almost certainly an undercount.

There is no safe level of lead for children. Even low exposures can weaken and alter health in ways that shape a child’s entire future. What’s more, neurodevelopmental disorders are more common than the national norm. Alaska reports that 12.6% of children ages 3–17 have ADHD, compared with 10.5% nationally.

Why this matters: The cost of inaction

Infants and children are not “small adults.” Pound for pound, they breathe more air, drink more water and eat more food. Their bodies and brains are still rapidly developing, making them especially vulnerable to harmful exposures. A toxic insult in early life, not just a major one, but an everyday one, can lead to both immediate symptoms and lifelong consequences.

Add to this the accelerating realities of climate change. Alaska is warming faster than any other U.S. state, and children are more vulnerable to the cascading health effects of heatwaves, wildfire smoke, flooding and extreme weather. Environmental threats are compounding, not isolated.

There is good news, and it shows what’s possible

In the past five years, Alaska has taken meaningful steps to strengthen children’s environmental health protections. The state secured CDC funding for lead-poisoning prevention and an Agency for Toxic Substances and Disease Registry cooperative agreement to improve surveillance and response. And in 2024, Alaska passed S.B. 67, banning firefighting foams containing PFAS “forever chemicals” linked to cancer, immune dysfunction and developmental harm.

These actions deserve recognition. They also prove that Alaska can act decisively when children’s health is at stake. When we protect children’s environments, we improve every aspect of their futures and you don’t have to be a policymaker or scientist to help protect Alaska’s kids.

What you can do

• Stay informed and speak up.

Public comment periods on environmental regulations, water quality standards and industrial permits matter. Showing up matters more.

• Support statewide investment in children’s environmental health.

Advocate for expanding lead testing, improving drinking water infrastructure and strengthening monitoring of toxic releases.

• Back policies that reduce exposures before they occur and vote with children’s health in mind.

Prevention is cheaper — and far more effective — than responding to harm after the fact.

The data in this new Children’s Environmental Health Profile is not a forecast; it’s a diagnosis. The question now is whether we act on it. Alaska’s children need clean water, clean air and a future free from preventable toxic exposures. We have the knowledge, we have examples of progress and we have a responsibility to ensure that every child grows up in an environment that helps them reach their full potential.

The health of Alaska’s children is not just a policy issue, it is a moral one. And it demands our action now.
