The Intersection of Environmental Health and Politics

Susan Kaplan has built a distinguished career working in federal and state government policy positions. She has contributed her expertise at Harvard University’s Kennedy School and taught at the University of Illinois, Chicago, and Northwestern University. Her book, A Healthy Union, showcases case studies of state-level environmental health policies that have emerged as best practices.

Kaplan reminds us that while federal protections from pollution and toxic chemicals have receded over the decades, states have increasingly stepped up to fill the gap. This shift began as early as the 1910s, when President Theodore Roosevelt led conservation efforts, and continued through the 1970s, an era dubbed the “Environmental Decade,” which saw the establishment of the EPA and pivotal environmental laws.

However, since the 1980s, federal protections have been eroding, prompting states to take more significant roles. Kaplan’s fascination with this history motivated her to explore and document successful state initiatives in her book. She highlights several policies from Massachusetts and Texas that date back to the late 20th century, enabling states to serve as “laboratories of innovation.”

The Role of Local and State Governments

While states play a vital role in environmental health, Kaplan emphasizes that local governments, such as city councils and school boards, have significant influence over everyday environments. These local bodies can focus on policies related to school infrastructure, ventilation, and more. She encourages individuals to form advocacy groups and engage in research, enabling them to influence local policymakers effectively.

Addressing a common concern, Kaplan discusses personal environmental responsibility, such as how individuals can maintain their lawns without harmful chemicals. She advises doing thorough research on the products used and considering alternative landscaping that requires fewer chemical inputs. Her insights reflect an empowering message about individual agency in environmental health.

Kaplan highlights that collective action can generate significant outcomes. She suggests forming small groups to advocate for environmental health policies locally. Her book provides evidence-backed success stories, including best practice policies that offer economic benefits and foster public health. These stories demonstrate how environmentally friendly practices can actually reduce costs and improve community wellbeing.

Despite challenges, Kaplan remains optimistic about the potential for states to lead the charge in environmental health improvements. Her book identifies states such as Massachusetts, New York, Texas, and regional collaborations like the Southeast Regional Partnership for Planning and Sustainability as examples of effective state-led efforts. By sharing successful state policies, she hopes to inspire further innovation and collaboration across the nation.
