A Call to Action

The health of our planet and our children are closely linked. Biodiversity—the variety of life on Earth—plays a critical role in keeping ecosystems and people healthy. Yet, biodiversity is rapidly declining, and climate change is worsening its impacts. Children are particularly vulnerable to these changes, as their developing bodies are more sensitive to environmental stressors and they face a longer lifetime of exposure.

Understanding the Crisis

What Is Biodiversity and Why Does It Matter?

Biodiversity refers to the variety of plants, animals, and microorganisms on Earth, as well as the ecosystems they form. It ensures clean air, water, and food, regulates diseases, and supports human health in countless ways.

However, human activity—deforestation, pollution, and overuse of natural resources—has caused biodiversity to decline at an alarming rate. Combined with climate change, these losses create a cycle of destruction that threatens not just the environment, but also our health.

Why Are Children More Vulnerable?

The impacts of biodiversity loss and climate change are particularly severe for children due to their unique vulnerabilities. These include biological factors and social dependencies that make them less able to cope with environmental changes. For example:

  • Their immune, respiratory, and nervous systems are still developing.

  • They breathe more air and consume more food relative to their size, increasing exposure to pollutants.

  • They depend on adults to provide safe environments and resources.

Key Areas of Impact on Pediatric Health

Microbial Diversity: Building Immunity

Microbial diversity, found in soil, water, and plants, is essential for the healthy development of a child’s immune system. When ecosystems lose biodiversity, children lose exposure to beneficial microbes, leading to a range of health issues.

  • What It Does: Microbial diversity in soil, water, and plants influences the microbes children are exposed to, which is essential for developing strong immune systems.

  • The Problem: Biodiversity loss reduces exposure to beneficial microbes, increasing risks of allergies, asthma, and inflammatory diseases.

Green Spaces: Nature’s Healing Power

Green spaces with diverse plant and animal life provide much more than aesthetic beauty. They are critical for children’s mental, emotional, and physical health, offering restorative environments for growth and learning.

  • Benefits: Access to biodiverse green spaces improves physical activity, mental health, and cognitive development in children.

  • Evidence: Studies show that exposure to diverse plant and animal life in parks and gardens boosts children’s emotional well-being and attention spans.

Heatwaves and Flooding: Rising Risks

As climate change drives more extreme weather, children are facing increasing risks from heatwaves and flooding. These events not only cause immediate health threats but also disrupt the ecosystems that help protect against them.

  • Heat-Related Illnesses: Children are at greater risk of heat exhaustion and dehydration during heatwaves, which are becoming more frequent due to climate change.

  • Flooding: Loss of ecosystems like wetlands, which absorb excess water, increases the risks of displacement, injury, and waterborne diseases.

Infectious Diseases: Expanding Threats

Climate change is enabling the spread of disease-carrying insects to new regions, putting children at a greater risk of infectious diseases. Biodiversity loss compounds this by reducing natural pest control systems.

  • Vector-Borne Diseases: Climate change allows disease-carrying insects like mosquitoes to thrive in new regions, increasing risks of illnesses like dengue and Lyme disease.

  • Children at Risk: With weaker immune systems, children are more susceptible to severe outcomes.

Air Pollution: Breathing Problems

The destruction of biodiversity-rich ecosystems contributes to worsening air pollution. For children, this means a higher risk of respiratory illnesses and developmental challenges.

  • The Link: Biodiversity loss contributes to air pollution as ecosystems that filter air—like forests—are destroyed.

  • Impact: Air pollution worsens asthma, bronchitis, and developmental issues in children.

Pediatric Medicine: Lost Potential

Biodiversity plays a key role in medical advancements. Many life-saving medicines have been discovered through the study of plants, animals, and microorganisms, a potential that is at risk with biodiversity loss.

  • Biodiversity’s Role: Many medicines are derived from plants, animals, and microorganisms. For example, antibiotics like penicillin come from fungi.

  • The Risk: Biodiversity loss could mean less availability of these medicinal sources.

Solutions and Mitigation Strategies

Ecosystem Restoration

Restoring biodiversity is critical for mitigating the impacts of climate change and creating healthier environments for children. These efforts can range from local projects like community gardens to global initiatives aimed at protecting ecosystems.

  • What Works: Rewilding efforts and urban planning that integrate biodiversity can restore ecosystems and improve air quality, reduce flooding, and create cooling effects.

  • Example: Restored urban green spaces have been shown to lower temperatures and improve local health outcomes.

Engaging Children in Biodiversity Initiatives

Getting children involved in biodiversity restoration not only helps ecosystems but also benefits their mental health and emotional well-being. These programs foster a sense of agency and environmental awareness.

  • Programs: Community gardens, tree-planting drives, and biodiversity education in schools.

  • Benefits: These activities not only improve ecosystems but also enhance children’s mental health, provide hands-on learning, and empower them to take action.

Policy and Community Action

Addressing biodiversity loss requires a collaborative effort across individuals, communities, and governments. Policymakers and organizations can create programs that protect and restore biodiversity while involving the public.

  • Global Initiatives: The UN Decade on Ecosystem Restoration is an example of efforts to promote biodiversity worldwide.

  • Local Efforts: Schools and communities can push for greener policies, like protecting wetlands or creating more biodiverse parks.

Research Gaps and Future Directions

While we know biodiversity loss and climate change harm children’s health, more research is needed to fully understand the long-term effects. By addressing these gaps, we can create better solutions tailored to children’s needs.

  • More studies are needed on the long-term health benefits of biodiversity restoration.

  • Research should focus on how interventions, especially in underserved communities, can best support children.

Summing Up

Biodiversity and climate change are not abstract issues—they directly impact children’s health today and their futures tomorrow. From the air they breathe to the spaces they play in, children are deeply connected to the natural world. Protecting biodiversity results in safeguarding the well-being of the next generation.

Call to Action

We can restore biodiversity by planting native species, reducing waste, and supporting conservation organizations. Communities can demand greener policies, and governments must prioritize ecosystem restoration. Together, we can protect our planet and ensure a healthier, safer future for all children.

Kids born near fracking sites 2-3 times more likely to develop leukemia: Study

Exposure to fracking and its effects is “a major public health concern,” said a study co-author.

Adding further evidence of the negative public health impacts associated with planet-heating fossil fuel pollution, new research published Wednesday found that children living in close proximity to fracking and other so-called “unconventional” drilling operations at birth face significantly higher chances of developing childhood leukemia than those not residing near such activity.

Existing setback distances, which may be as little as 150 feet, are insufficiently protective of children’s health.

The peer-reviewed study, published in Environmental Health Perspectives, examined the relationship between residential proximity to unconventional oil and gas development (UOGD) and risk of acute lymphoblastic leukemia (ALL), the most common form of childhood leukemia.

Researchers compared 405 children ages 2 to 7 who were diagnosed with ALL in Pennsylvania between 2009 and 2017 to a control group of 2,080 children without leukemia matched on birth year. They measured the connection between in utero exposure to unconventional oil and gas activity and childhood leukemia diagnoses in two exposure windows: a “primary window” of three months pre-conception to one year prior to diagnosis and a “perinatal window” of pre-conception to birth.

Children with at least one fracking well within 2 kilometers (1.24 miles) of their birth residence during the primary window had 1.98 times the odds of developing ALL compared with those whose neighborhoods were free from such fossil fuel infrastructure, they found. Children who lived within 2 kilometers of at least one fracking well during the perinatal window were 2.8 times more likely to develop ALL compared with their unexposed counterparts.

Accounting for maternal race and socio-economic status reduced the strength of these relationships, but only slightly, with the adjusted odds of developing childhood leukemia 1.74 and 2.35 times higher for those exposed to UOGD during the primary and perinatal windows, respectively.

“Unconventional oil and gas development can both use and release chemicals that have been linked to cancer,” study co-author Nicole Deziel, an associate professor of epidemiology at the Yale School of Public Health, said in a statement.

Last summer, Physicians for Social Responsibility uncovered internal records revealing that since 2012, fossil fuel corporations have injected potentially carcinogenic per- and polyfluoroalkyl substances (PFAS), or chemicals that can degrade into PFAS, into the ground while fracking for oil and gas—after former President Barack Obama’s Environmental Protection Agency approved their use despite agency scientists’ concerns about toxicity.

The possibility that children living in close proximity to such sites are “exposed to these chemical carcinogens is a major public health concern,” said Deziel.

Roughly 17.3 million people in the United States, including nearly four million children, live within a half-mile radius of active oil and gas production, according to the Oil & Gas Threat Map, a geospatial analysis released in May.

Not only do those people have a greater risk of suffering severe health problems from toxic air pollution, but as the research published Wednesday notes, fracking also contaminates drinking water—creating another pathway of exposure to cancer-linked chemicals.

The new study adds to a growing body of literature documenting the deleterious health and environmental consequences of fracking and other forms of fossil fuel extraction.

Research published earlier this year found that residential proximity to UOGD is correlated with a higher risk of dying early. More broadly, the World Health Organization warned last year that burning coal, oil, and gas is “causing millions of premature deaths every year through air pollutants, costing the global economy billions of dollars annually, and fueling the climate crisis.”

Other recent studies have estimated that slashing energy-related air pollution would prevent more than 50,000 premature deaths and save $608 billion per year in the U.S. alone, while eliminating greenhouse gas emissions by 2050 would save 74 million lives around the globe this century—demonstrating that the “mortality cost of carbon” is astronomical.

“Fracking threatens every person on the planet, directly or indirectly. It should be banned entirely.

—Wenonah Hauter, Executive Director, Food & Water Watch

Despite this obvious case for rapid decarbonization, President Joe Biden has yet to use his executive authority to cancel nearly two dozen fracked gas export projects that are set to unleash pollution equivalent to roughly 400 new coal-fired power plants.

The researchers behind the paper published Wednesday hope that their findings will be used to improve public policy, including better regulation of “setback distances”—the required minimum distance between a private residence or other sensitive location and fracking wells.

Setback distances are currently being debated across the U.S., with some communities calling for setback distances to be lengthened to more than 305 meters (1,000 feet) or as far as 1,000 meters (3,281 feet), the authors wrote.

In Pennsylvania, where the study was based, the current setback distance is 152 meters (499 feet), up from 61 meters (200 feet) in 2012. Researchers, meanwhile, observed elevated risks of childhood leukemia from fracking activity within a 2,000 meter (6,562 feet) radius.

“Existing setback distances, which may be as little as 150 feet, are insufficiently protective of children’s health,” lead author Cassandra Clark, a postdoctoral associate at the Yale Cancer Center, said in a statement. “We hope that studies like ours are taken into account in the ongoing policy discussion around UOG setback distances.”

Other critics of fracking have demanded far more extensive federal action, including prohibiting the practice entirely.

As “hundreds of scientific studies and thousands of pages of data have already shown over the last decade,” Food & Water Watch executive director Wenonah Hauter said last year, “fracking is inherently hazardous to the health and safety of people and communities in proximity to it.”

“This says nothing of the dreadful impact fossil fuel extraction and burning is having on our runaway climate crisis,” she added. “Fracking threatens every person on the planet, directly or indirectly. It should be banned entirely.”

How To Talk To Children About Climate Change

The Museum of Natural History in New York is a regular excursion for Jody Neal and her two kids. Teaching her children about the environment and how global warming is affecting it, is important to Jody, but she also doesn’t want to alarm them. Awareness about climate change is growing thanks mainly to younger people who have been marching around the world to draw attention to the issue. Schools and the media have been discussing it more, too.
