Restoring John Muir's Hetch Hetchy: Is It Worth It?

Aug 8, 2012

It’s been nearly 100 years since Congress authorized the City of San Francisco to build the O’Shaughnessy Dam in Yosemite National Park. This is the dam that turned Hetch Hetchy Valley into Hetch Hetchy reservoir, providing water and electricity to San Francisco and surrounding cities. John Muir and a emerging Sierra Club fought against this project proposal for nearly 12 years before Congress passed the Raker Act in 1913, giving San Francisco the authority to build the dam, power generators, and delivery system to the Bay Area.

It’s our planet’s most valuable resource, cities are powered by it, wars are fought over it, and life depends on it...

“We think of it as air, infinite and inexhaustible, but when you use water in such quantities that it exceeds the system’s capacity to renew itself, we’ve got a problem,” states the trailer for the new documentary film Last Call at the Oasis (view trailer below).

 

On today's Your Call we’ll reflect on Earth Day. Environmental journalist Mark Hertsgaard believes that Earth Day is becoming a bland, tired ritual that polluters and politicians have learned to ignore or co-opt. It’s time to reclaim Earth Day and return it to its 1970s roots when millions took to the streets. What will it take to get millions into the streets today? Join us at 10 or email feedback@yourcallradio.org. How would you save Earth Day and the environmental movement? It’s Your Call with Holly Kernan, and you.

California's outer coast once boasted 27 miles of Bay Area beaches. Up until the 20th Century, these beaches provided a natural buffer for the inner land areas; then came freeways, airports and downtowns. KALW's Ben Trefny spoke with Robin M. Grossinger, Senior Scientist and Historical Ecology Program Director at the San Francisco Estuary Institute about California beaches, landscape heritage and how some of these areas have rebuilt themselves.

 

On today's Your Call, we’ll have a conversation with Thomas Linzey, author of “Be the Change: How to Get What You Want in Your Communityand Shannon Biggs, author of “The Rights of Nature.” How can communities defend themselves from corporate interests? Are local laws the answer? Join us at 10 or email feedback@yourcallradio.org. How are you organizing for change in your community? And what changes would you like to see? It’s Your Call with Rose Aguilar, and you.
