The ocean, far from being a bunch of water and rocks, is a living being – and THE life support system for humanity. In “Living Blue,” Krista talks with acclaimed oceanographer Sylvia Earle about the beauty, mystery, and peril that faces the planet and our oceans. Earle is known affectionately by her fellow scientists as “Her Deepness,” a nickname she earned in 1979. That year, she became the first – and still the only – person to walk solo on the bottom of the world, on the ocean floor, under a quarter mile of water, 600 pounds of pressure per square inch. She’s watched humanity’s enduring fascination with “outer space”; while she has delighted in “inner space” – the alien and increasingly endangered worlds beneath earth’s waters. These frontiers, as Sylvia Earle points out, are our very life support system. She takes us inside the knowledge she’s gathered there in her 76 years.
