Imagine being suddenly plunged into total darkness. You have one job: find the exit. To get there, you must swim through gaps – some barely large enough to slide through. Oh, and you could lose oxygen at any moment. “Well, that's my workplace,” says cave diver Jill Heinerth. Jill explores the water sources inside the Earth, working with biologists, physicists, paleoclimatologists, archaeologists and more to understand our planet’s past and prolong its future. “Our water planet is not just rivers, lakes and oceans. It's this vast network of groundwater that knits us all together,” she says. To learn more about Jill’s work as an underwater explorer, watch her #TEDTalk at go.ted.com/underwatercaves
