In 21 short books, Penguin Classics brings you the new canon of great environmental works Over the past 75 years, a new canon has emerged. As humans have driven the living planet to the brink of collapse, visionary thinkers around the world have raised their voices to defend it. Their words have endured, becoming the classics that define the environmental movement today. From the Congo Basin to the traditions of the Kikuyu people, these lucid, incisive writings explore the sacred power of trees, and why humans lay waste to the forests that keep us alive.
