Emmy-award nominee and environmental advocate Shailene Woodley swims with a "Protect the Turtles" message in the Sargasso Sea from the MY Esperanza. The Greenpeace ship Esperanza is on an expedition to the Sargasso Sea, a unique region in the North Atlantic Ocean that is home to a diverse array of marine life, including loggerhead and green sea turtles. The journey will see Greenpeace and University of Florida researchers team up to study the impact of plastics and microplastics on marine life and the importance that the Sargasso’s drifting Sargassum seaweed habitat has for the development of juvenile sea turtles.
