Robert Redford Is Worried About Colorado River

Well known as an environmentalist, Robert Redford is embarking on a new journey to raise awareness. He'll be the narrator of a new IMAX film about a Grand Canyon River Trip. The reason for the film is to raise awareness about water conservation as a drought threatens the area around the Colorado River.

From his office in Park City Utah, Redford explained a little more about the imminent problem. "The river is endangered now on a number of fronts. Its volume is shrinking because of a megadrought cycle that's now facing the Southwest, and some scientists predict that it could last into the next century."

This information refers to a recent study forecasting that lakes Powell and Mead could dry up in the next 13 years amid climate change and increasing demand for water.

Grand Canyon Adventure: River at Risk 3D opens nationwide Friday.
