In this lyrical meditation on America's wildlands, Aldo Leopold considers the different ways humans shape the natural landscape, and describes for the first time the far-reaching phenomenon now known as 'trophic cascades'. The material here was first published in Leopold's work A Sand County Almanac.
This book is part of Green Ideas, a series of twenty short books from Penguin Classics that brings you the ideas that have changed the way we think and talk about the living Earth.
Aldo Leopold (1887-1948) was a forester and conservationist whose writings on wildlife ecology sowed the seeds of contemporary environmental thought.
