Australian researchers study oysters' resilience in face of climate change

Moreton Bay, on Australia's eastern coast near Brisbane, has lost over 95% of its oyster reefs over the past few centuries. These reefs, one of the world's most-degraded marine ecosystems, are not just the source of a culinary delicacy, but help to filter seawater and protect shorelines from the effects of storms, sea level rise and increasing temperatures. Leila Goldstein visited a research facility to report on how scientists are studying oysters' resilience in the face of climate change.
