Book excerpt: About the Book: The U.S. legal system was built to address predictable health and environmental injuries, but it can seize up when health or environmental crises combine legally confounding fact patterns with huge humanitarian and financial stakes. Because these crises present serious societal challenges that affect large slices of America, however, they must be addressed--and resolved--in an open, fair, and equitable fashion. Looking Back to Move Forward: Resolving Health & Environmental Crises, released by the State Energy & Environmental Impact Center at the New York University School of Law, describes the tools that advocates, judges, legislators, and policymakers have applied to address and resolve--with varying levels of success--seven major health and environmental crises of our time. From Diethylstilbestrol to Dieselgate, the seven crises provide a rich source of insights that should inform and guide how the legal system responds to future health and environmental crises--including crises that already are on our doorstep, such as the opioid and climate crises. About the State Energy & Environmental Impact Center: The non-partisan State Energy & Environmental Impact Center supports state attorneys general in defending and promoting clean energy, climate, and environmental laws and policies. About the Editor: Hampden T. Macbeth is a Staff Attorney with the State Energy & Environmental Impact Center, New York University School of Law
