About the Author

From saving the whales of the Antarctic to studying the salmon of Alaska, Casson Trenor has worked to support stewardship of our marine resources in all five oceans and countless seas. Trenor has extensive experience and expertise: he has stalked the fetid warehouses of Tsukiji fish market in Tokyo, spent two months journeying by ship along the Antarctic coast, berthed on leaking wrecks off Central Pacific islands, and gone octopus fishing with holy men on the Island of Yap. In thousands of conversations with fishermen around the world, he has heard one statement repeated: “The fish are gone.”

Trenor currently holds the position of Senior Markets Campaigner with Greenpeace USA, where he spearheads the organization’s efforts to hold restaurants and supermarkets accountable for their seafood sustainability practices and to help educate the public about the global fisheries crisis.  He is a frequent commentator on sustainable seafood issues and has appeared in regional and national publications, including NPR, the New York Times, Christian Science Monitor, San Francisco Chronicle, Los Angeles Times, Seattle Times, Tampa Tribune, the UTNE Reader, Hemispheres, Tokyo Weekender, and Edible San Francisco. He is also the subject of an extensive multi-part feature story in the Japanese newspaper Kochi Shimbun. In October 2009, Trenor was awarded the title “Hero of the Environment” by TIME Magazine.

In his recent book The Whale Warriors, author Peter Heller, a contributing editor to National Geographic Adventure and Outside magazines, captures Trenor’s dedication to ocean conservation through his efforts to end illegal whaling. Trenor is a main character in Heller’s factual account of the exploits of one small, rusty ship determined to take on the entire Japanese whaling fleet in the Southern Ocean in 2005 and 2006.

Born in Washington State and living in San Francisco, Trenor speaks five languages, has traveled to over forty countries, and holds an MA in International Environmental Policy from the prestigious Monterey Institute of International Studies.

Sustainable Sushi: A Guide to Saving the Oceans One Bite at a Time is Trenor’s first book.
