Best-selling author Karen Pinchin is our guest on this episode of Explore. Her new book, Kings of their Own Ocean, is the phenomenal tale of an incredible fish, the bluefin tuna, which has gone from being the cornerstone of the Roman Empire to the much sought-after catch brought to near extinction in the past century in our own boom-bust, globalized economy. Ultimately, this is a heartening wildlife story, filled with an incredible cast of characters, a globetrotting look into the history of bluefin tuna and how regular people, along with industry, scientists and governments, banded together and brought this magnificent fish back from the brink of being completely wiped out. Karen Pinchin is an award-winning investigative journalist whose work has appeared in Canadian Geographic along with Scientific American, Vox, The Globe and Mail, The Walrus, National Geographic, the Canadian Press and Maclean's Magazine. Originally from Toronto, she teaches narrative non-fiction writing in the Masters of Fine Arts program at the University of King’s College in Halifax.
