What's happening to the food chain in the ocean?

On the next Your Call, we'll have a conversation about why we should be concerned about our ocean's food supply. How are issues like the health of top predators and overfishing affecting the ocean? A bill that would ban the practice of shark-finning is being considered in Sacramento. How will we be affected by changes to the ecosystem? Join us at 10 or email feedback@yourcallradio.org.

Your Call 120808 Global Commons -- Whales & Sharks

How is the environment for whales and shark changing? On the next Your Call, we continue our series on the global commons, with a discussion about the state of whales and sharks. According to the United Nations about ten million sharks are killed each year for their valuable fins. Whales are also facing ever-increasing dangers despite the 20-year ban on commercial whaling. So what's been done to save these sacred and precious creatures? And can we save them? It's Your Call, with Rose Aguilar and you.

Guests: David McGuire, conservation filmmaker, a field associate of the California Academy of Sciences and a shark advocate.

Douglas Long, Chief Curator, Natural Sciences at Oakland Museum of California. formerly chair of the Department of Ornithology and Mammalogy at the California Academy of Sciences, he is currently teaches in the Department of Biology at Saint Mary's College in Moraga.
