Book excerpt: In twenty short books, Penguin brings you the classics of the environmental movement. In The Dragonfly Will Be the Messiah, the celebrated pioneer of the 'do-nothing' farming method reflects on global ecological trauma and argues that we must radically transform our understanding of both nature and ourselves in order to have any chance of healing. 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.
