Abstract: In The Making of Environmental Law, Richard J. Lazarus offers a new interpretation of the past three decades of this area of the law, examining the legal, political, cultural, and scientific factors that have shaped—and sometimes hindered—the creation of pollution controls and natural resource management laws. He argues that in the future, environmental law must forge a more nuanced understanding of the uncertainties and trade-offs, as well as the better-organized political opposition that currently dominates the federal government. Ranging widely in his analysis, Lazarus not only explains why modern environmental law emerged when it did and how it has evolved, but also points to the ambiguities in our current situation. As the field of environmental law "grays" with middle age, Lazarus's discussions of its history, the lessons learned from past legal reforms, and the challenges facing future lawmakers are both timely and invigorating.
