In this week’s show Beth speaks with science writer, educator, and scientist Dr. Lisa Gardiner about her recent book Reefs of Time: What Fossils Reveal about Coral Survival. Lisa studied the fossil remains of ancient coral reefs, which also suffered from environmental challenges. In our conversation, you’ll hear about how the past shapes the present, and future, of these amazing invertebrates that are keystones in ocean ecosystems. Her book describes the risks the current environment pose to these amazing organisms and the ecosystems they create, but also much much more of the significance and elegance of the corals and the reefs.
