For more than 30 years, renowned anthropologist Wade Davis has traveled the globe, studying the mysteries of sacred plants and celebrating the world’s traditional cultures. His passion as an ethnobotanist has brought him to the very center of indigenous life in places as remote and diverse as the Canadian Arctic, the deserts of North Africa, the rain forests of Borneo, the mountains of Tibet, and the surreal cultural landscape of Haiti. In Light at the Edge of the World, Davis explores the idea that these distinct cultures represent unique visions of life itself and have much to teach the rest of the world about different ways of living and thinking. As he investigates the dark undercurrents tearing people from their past and propelling them into an uncertain future, Davis reiterates that the threats faced by indigenous cultures endanger and diminish all cultures.

It’s an alarming if little-known fact: one of the world’s mightiest rivers, the Colorado, no longer reaches the sea. Every drop of its water is allocated to agriculture and communities along the way and none remains for the Colorado Delta at river’s end, a once-thriving estuary that supported North America’s most diverse biosphere. Grand Canyon: A River at Risk draws attention the river’s plight as well as to the larger issue of the looming global water crisis. It follows Robert F. Kennedy Jr., a leading advocate for water conservation and river restoration, eminent ethnobotanist Wade Davis, and their two daughters on a rafting adventure down the Colorado. Their compelling journey illuminates both the challenges and the many opportunities that exist for conserving and restoring the world’s watersheds. Combining science and adventure with glorious imagery and locations, the book delivers a message of hope and inspiration for all people of the world.
