This interdisciplinary collection of essays explores in-depth a topic previously neglected by scholars: John Steinbeck’s early continuing preoccupation with ecology and marine biology and the effect of that interest on his writings. Written by scholars from various disciplines, the essays offer a dynamic contribution to the study of John Steinbeck by considering his writings from an environmental perspective. They reveal Steinbeck as a prophet that was ahead of his time and supremely relevant to our own.
