The book explores the cultures of peoples around the world, portraying both their diversity and the threats they face. Other contributors included not only western writers, such as Laurens van der Post, Noam Chomsky, Claude Lévi-Strauss, but also indigenous people, such as Davi Kopenawa Yanomami and Roy Sesana.
