Every drop ofits water is allocated to agriculture and communities along the way and none remains for the Colorado Delta at river’s end, aonce-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.

Combining science and adventure with glorious imagery and locations, the book delivers a message of hope and inspiration for all people of the world.
