Sylvia Earle (oceanographer, explorer)

No ocean, no life. No ocean, no us, says Sylvia Earle, who has been fighting to save the oceans for decades. She's an explorer, marine biologist, oceanographer, as well as former chief scientist of NOAA. She resigned because she wanted to be free to speak my mind. In total, she spent nearly a whole year of her life underwater, snorkeling and discovering what is happening in the oceans. She is the one who performed the deepest untethered sea walk and was nicknamed Her Deepness. https://www.ceskatelevize.cz/porady/10441294653-hyde-park-civilizace/9271-english-versions/44932-sylvia-earle/
