The Greenpeace ship Esperanza traveled to the Arctic to show what's at stake as melting sea ice opens the region to offshore drilling and unsustainable fishing. Scientists explored the little known waters and sea floor of the Bering and Chukchi Seas with small research submarines, and made discoveries that will help protect this pristine environment. We met with the people who have called this region home for generations, and joined a growing global movement to save the Arctic. http://www.savethearctic.org/
