Yosemite Preservationists Launch Campaign to Restore Hetch Hetchy Valley

Environmental activists gathered at San Francisco's Ferry Building to launch a campaign aimed at restoring a section of the Yosemite Valley called Hetch Hetchy. Almost 90 years ago Hetch Hetchy was converted into a reservoir that supplies water to San Francisco and much of the Bay Area. Now activists are eager to restore it to its natural state. But the effort faces widespread opposition. Alex Kekauoha reports.
