West Coast Sardines Vanishing, Threatening Ecosystem

Hosted by and

Maybe it's time to hoard those unopened sardine cans. The sardine population off the coast of California is disappearing. Last fall, scientists noted the population had dropped 72 percent since its peak seven years ago, and that means trouble up the food chain.  Sea mammals and birds are dying of starvation, and local fishermen are losing a lot of money. Sardines populations have come and gone in the past. Is this just a natural cycle, or is this telling us something about the health of our oceans? Reporter Tony Barboza covers the environment for the Los Angeles Times.
