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.

Together, these books show the richness of environmental thought, and point the way to a fairer, saner, greener world."
