We continue our Earth Month shows with a guest from Lake Okoboji, Iowa who has most certainly lived a life of adventure.

David Thoreson is an explorer, storyteller, photographer, and ocean and climate advocate. He is an Explorers Club fellow and the first American explorer in history to sail the NW Passage in both directions. David has sailed more than 70,000 nautical miles, including below the Antarctic Circle, three times across the Atlantic, eight times over the Arctic Circle, twice around Cape Horn and in 2009-2010, a 28,000-mile circumnavigation of North and South America. His documentary of that voyage was nominated for an Emmy and published in the beautiful photo book, One Island, One Ocean.
