Some people serve as ambassadors to Great Britain or Japan.
Dr. Sylvia Earle has long been America's foremost ambassador to the ocean blue. This marine scientist has tracked giant sperm whales from South Africa to Alaska, trying to achieve the intimacy with whales that Dian Fossey did with gorillas. She's lived for two weeks in a four-room underwater hotel and laboratory on the ocean floor. And she's served as chief scientist for the National Oceanic and Atmospheric Administration where she monitored the ocean's health. When she's not on or in the ocean, she lives in Oakland, California, where her Deep Ocean Engineering and Deep Ocean Technologies builds undersea exploration vehicles.
