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.

Protect Our Water & Safeguard Our Future!

Defend Clean Water Act from Project 2025 Threat

Water as a Sacred Force Across Cultures

Many cultures around the world revere water as a sacred and life-giving force, recognizing its profound symbolic and spiritual significance. In Hinduism, water is regarded as the essential sustainer of life, without which most living beings, including humans, would not be able to survive. Indigenous cultures, such as the Lakota Sioux in North America, honor water as a sacred element central to life and ceremonies, often referring to it as “Mni Wiconi,” meaning “Water is Life.” In Buddhism, water symbolizes purity, clarity, and calmness, representing a path to spiritual enlightenment. Across African traditions, water is scarce and precious, reflecting the community’s resilience. This universal reverence for water underscores its critical role in sustaining life and reinforces the need for its preservation across diverse global communities.

Protecting Our Water: The Importance of the Clean Water Act

The Clean Water Act (CWA), enacted in 1972, is a landmark U.S. federal law aimed at regulating water pollution to restore and maintain the integrity of the nation’s water bodies. However, the act is under threat from initiatives like Project 2025, which proposes a conservative restructuring of the Environmental Protection Agency (EPA), prioritizing industrial and business interests over environmental protections. By undermining the Clean Water Act and reducing federal oversight, Project 2025 endangers access to clean water for vulnerable communities, particularly those near industrial zones.

The History Behind the Clean Water Act

The Clean Water Act was born out of a growing environmental crisis in the mid-20th century. Before its enactment, the Federal Water Pollution Control Act of 1948 was the first U.S. law to address water pollution, but it lacked the enforcement mechanisms to make a significant impact. During the 1960s, environmental concerns escalated, particularly following events like the 1969 fire on Ohio’s Cuyahoga River, which was so polluted it ignited when an oil slick caught fire. Public outcry, combined with the environmental movement of the time, fueled the demand for stronger water protection laws. This momentum led to the drafting of the Clean Water Act in 1972, aimed at restoring and maintaining the chemical, physical, and biological integrity of the nation’s waters​.

Key Provisions of the Clean Water Act

Here are the key provisions of the Clean Water Act, designed to protect our nation’s waters from harmful pollution and ensure long-term environmental sustainability:

  • Permits and Regulation: Facilities that discharge pollutants into surface waters must obtain permits under the National Pollutant Discharge Elimination System (NPDES). This system helps monitor and regulate pollutants from industries, municipalities, and certain agricultural activities.

  • Water Quality Standards: States are required to establish water quality standards for various bodies of water, ensuring pollution levels remain below harmful thresholds. If these standards aren’t met, more stringent pollution control measures are implemented.

  • Protection of Wetlands and Streams: Wetlands and small streams, vital ecosystems for filtering water and providing habitat, are protected under the CWA. Recent Supreme Court decisions have clarified the types of water bodies covered, emphasizing the importance of maintaining ecological balance.

  • Pollution Control: The CWA encourages the development of technology to limit pollution. Facilities must adhere to technology-based standards, ensuring that water pollutants are minimized as much as possible.

  • Non-Point Source Pollution: In addition to direct discharges, non-point source pollution, such as agricultural runoff, is a significant contributor to water pollution. The CWA provides support for research and practices aimed at reducing this type of pollution.

  • Public Participation: The CWA allows citizens to take legal action against polluters and government agencies that fail to enforce the Act. This provision ensures accountability and gives the public a role in protecting water resources.

Health Implications of Unprotected Water

If water bodies are not adequately protected, water pollution can have severe health consequences for both humans and wildlife. Contaminated water may harbor harmful substances like heavy metals, pesticides, industrial chemicals, and pathogens, leading to various health issues. Exposure to polluted water can cause cancer, gastrointestinal illnesses, reproductive problems, and neurological disorders. For instance, chemicals like lead and mercury can impair brain function and development, while certain pollutants are linked to male fertility issues. Vulnerable populations, including children, pregnant women, and the elderly, are particularly at risk. Long-term exposure to polluted water can result in chronic health problems, overwhelming public health systems and endangering future generations.

Why the Clean Water Act Matters Today

The Clean Water Act has been instrumental in improving water quality across the United States. Since its implementation, many rivers, lakes, and other bodies of water have shown significant improvement. However, challenges remain, particularly with non-point source pollution and groundwater contamination, as well as the latest and most significant threat, Project 2025.

Project 2025 envisions a conservative restructuring of the EPA that places industrial and business interests over the imperative for clean water and air, potentially endangering communities and paving the way for toxins, chemicals, and oil to enter our waterways. It undermines the EPA’s capacity to safeguard diverse communities and the human right to clean water by favoring the self-interest of corporations over environmental and public health protections. This initiative threatens to reverse the progress made by the Clean Water Act, removing standards that protected all of us across the country and creating a patchwork of state standards that leaves vulnerable populations, such as low-income and Indigenous communities, at greater risk. By limiting the EPA’s authority and diminishing legal recourse for affected individuals, Project 2025 weakens the essential safeguards that protect public health and the environment.

What You Can Do: Reject Project 2025, Reject Trump & Vote Blue

Individuals play an essential role in supporting the goals of the Clean Water Act and protecting water resources. Here are a few ways you can make a difference:

  • Learn about the threats that pollution and toxins pose to your health and the health of your loved ones.

  • Support policies and legislation aimed at strengthening water protections.

  • Participate in local clean-up efforts to protect wetlands, rivers, and other bodies of water.

The Clean Water Act has laid the foundation for a cleaner, healthier environment, and it’s up to all of us to continue building on that legacy. By staying informed and taking action, we can help safeguard water resources for future generations.

Don’t operate out of fear, operate out of hope, because with hope everything is possible.

Climate Litigation: A Growing Force in the Fight Against Climate Change



As the world faces increasingly severe climate impacts, governments and corporations are being held accountable through a surge of climate-related lawsuits. A recent study, Research Areas for Climate Litigation, conducted by the Union of Concerned Scientists (UCS) in September 2024, highlights the critical role of climate litigation in driving action where traditional policy-making has often fallen short.

The Rise of Climate Litigation

Since 2015, more than 1,800 climate-related lawsuits have been filed worldwide, with at least 230 new cases in 2023 alone. The United States, United Kingdom, and Australia have become the primary hubs for this legal activity, while other regions, especially parts of Africa, have seen limited litigation.

The UCS study emphasizes that this growing body of legal action requires strong scientific evidence to be effective. To that end, scientists and researchers are increasingly collaborating with legal teams to provide the necessary data, helping courts make informed decisions on climate cases. The study aims to bridge gaps between science and law by identifying key research priorities that can strengthen future litigation efforts.

Key Research Areas for Climate Litigation

The study highlights three priority research areas that are essential for advancing climate lawsuits:

  1. Attribution Science: This field connects specific climate impacts to particular sources of emissions. Courts need this science to establish a clear causal link between climate change and its effects, such as extreme weather events. The study calls for more geographically diverse research, particularly in regions like the Global South, where climate data is scarce.

  2. Climate Change and Human Health: Legal arguments are increasingly focusing on the health impacts of climate change. Vulnerable groups, including older adults, infants, people with disabilities, and those in poverty, are especially at risk from worsening air quality, heatwaves, and water scarcity. The study points to a need for more research linking climate change to health outcomes like asthma, cardiovascular diseases, and heat-related illnesses.

  3. Economic Modeling: Courts rely on economic data to assess the costs of climate change. This includes not only the direct damages caused by extreme weather events but also the costs of adapting to a changing climate and the economic opportunities lost due to inaction. The study calls for robust economic modeling that can predict future costs and benefits under different climate scenarios.

Strategic Research Areas for the Future

Beyond the priority areas, the study identifies five strategic research areas where further scientific evidence is needed to support climate litigation:

  1. Legal and Financial Accountability: Holding corporations accountable for their emissions, particularly in industries like fashion and cement, requires more detailed research on how financial institutions contribute to climate change by funding fossil fuel projects.

  2. Disinformation and Greenwashing: The study stresses the importance of exposing and countering misleading claims made by corporations about their environmental practices, which can mislead consumers and delay meaningful climate action.

  3. Fair Share Analysis and Compliance: Understanding whether corporations and nations are meeting their climate goals is critical. The study highlights the need for standardized emissions metrics and tracking, especially for corporations with complex supply chains.

  4. Environmental and Social Impacts: Research on how climate change affects ecosystems, biodiversity, and human communities—especially in remote regions with limited data—is vital for comprehensive environmental impact assessments.

  5. Emissions Accounting and Reductions: Courts need better methods for tracking and reducing emissions, particularly those related to the indirect effects of products, known as Scope 3 emissions. The study also calls for research into the effectiveness of renewable energy credits and other mitigation strategies.

Losses and Damages: A Cross-Cutting Theme

One of the study’s most important cross-cutting themes is losses and damagesthe economic and non-economic harms caused by climate change that can’t be prevented through adaptation or mitigation. The study calls for more research to quantify these losses, especially in terms of intangible cultural heritage, social structures, and ways of life. Understanding these losses is critical for communities seeking reparations for the damage caused by climate change.

Why This Study Matters

As climate litigation accelerates globally, the need for solid scientific research to support these cases becomes more urgent. The UCS study provides a roadmap for scientists looking to contribute to the legal battle against climate change by focusing on areas where their work can have the greatest impact. This research will not only improve the effectiveness of climate lawsuits but also push governments and corporations to take more meaningful climate action.

Summing Up

Climate litigation is emerging as a powerful tool in the fight against climate change. With over 1,800 lawsuits filed since 2015, the legal community is increasingly relying on science to prove the connections between climate change, its impacts, and the entities responsible. The Union of Concerned Scientists’ 2024 study highlights the critical research areas—such as attribution science, health impacts, and economic modeling—that will strengthen these legal efforts.

For those interested in how climate change is being addressed through legal channels, this study underscores the vital role that science plays in holding governments and corporations accountable. As the impacts of climate change worsen, the importance of this intersection between science and law will only grow.
