In 2008, Marcus rafted across the Pacific Ocean from California to Hawaii on JUNK, a raft floating on 15,000 plastic bottles, 30 sailboat masts lashed to form a deck, and a Cessna airplane fuselage as a cabin. The journey, 2,600 miles in 88 days, brought attention to the issue of plastic trash filling the world’s oceans and solutions. JUNKraft was followed by a 2000-mile speaking tour from Vancouver, Canada to Tijuana, Mexico with his wife, Anna Cummins. Recently, they co-founded 5 Gyres Institute to study and communicate plastic pollution in the 5 large ocean gyres in the world. Marcus was elected a National Fellow of the Explorers Club in 2010.
