In "Yosemite: Fate of Heaven," Robert Redford narrates this look at Yosemite National Park, which explores the damage - and potential damage - to the environment being brought on by an enormous amount of tourism.

Beautifully photographed, with Redford's readings from diaries of early explorers juxtaposed with interviews that explain the park's history and its modern-day place in the environment, "Yosemite" suggests that protecting areas like this is not an impossible task but that it has become steadily more difficult to raise the awareness of the general public.
