Challenger Deep: What They Found 7 Miles Deep In The Mariana Trench

Nearly seven miles down, nothing grows. So how did all of this end up on the seabed? #challengerdeep #marianatrench #oceandiscovery ⚠️ https://www.youtube.com/watch?v=WDvqkZpCwlA&list=PL0H5lrcTOMY8tzqBkPBDC3vdhiaLAcy8N&index=8&pp=iAQBsAgC 🌊 In nineteen ninety-eight, a Japanese robot filmed a plastic bag lying on the floor of the Mariana Trench, nearly seven miles down, fourteen years before any human being would reach that seabed again. But it was not the strangest thing waiting down there. Nothing grows at the bottom of the Challenger Deep. Sunlight has never reached it, nothing photosynthesises, and there is no food except what sinks in from the world above. Which means almost everything anyone has ever found down there arrived from somewhere else. We go through seven of those finds. So what is actually down there, seven miles under the Pacific? And why does the most remote place on the planet keep handing back things that came from us? Let's find out. 🧭 Chapters 0:00 The Marker in the Muscle 0:42 1. The Wood Eaters 2:11 2.
