In twenty short books, Penguin Classics brings you the ideas that have changed the way we think and talk about the living Earth. Provocative and playful, All Art is Ecological explores the strangeness of living in an age of mass extinction, and shows us that emotions and experience are the basis for a deep philosophical engagement with ecology. Over the past 75 years, a new canon has emerged. As life on Earth has become irrevocably altered by humans, visionary thinkers around the world have raised their voices to defend the planet, and affirm our place at the heart of its restoration. Their words have endured through the decades, becoming the classics of a movement. Together, these books show the richness of environmental thought, and point the way to a fairer, saner, greener world.
