With its intricate layers of international, federal, and state protections, environmental law is more established than animal law. Yet, animal law faces many of the same legal and strategic challenges that environmental law faced in seeking to establish a more secure foothold in the United States and abroad. As such, animal law stands to gain valuable insights from the lessons of the environmental law movement. In the Second Edition of this book, Prof. Randall S. Abate has assembled an experienced team of 36 academics, advocates, and legal professionals from the environmental and animal law fields to examine the experiences of these two fields. Drawing on lessons from history, politics, and law, the 29-chapter book examines how environmental law's successes and shortcomings can inform animal law, and how the two fields can work together to secure mutual gains in the future.
