Grand Canyon Adventure: River at Risk 3D

This documentary combines exhilarating river-rafting action on America's most iconic river, family fun and the grandeur of the Grand Canyon to tell an engaging story of how ordinary people can make a difference for our parched planet - one that is running out of clean, fresh water so fas that U.N. estimates that 40% of the world could face life-threatening shortages by the year 2050.
