There is no point of no return

In twenty short books, Penguin brings you the classics of the environmental movement. Emphasizing joy in the world, human cooperation and the value of all living things, this selection of Arne Naess' philosophical writings is filled with wit, learning and an intense connection with nature. 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.
