I made this image in the Inupiat village of Kaktovik, Alaska. Every fall after the community’s annual subsistence hunt of bowhead whales, polar bears arrive to feed off the whale carcass scraps and bones. Climate change has affected the migration and diet of polar bears, which have grown increasingly hungry as melting sea ice impairs their ability to hunt seals on the ice sheet. Meanwhile, scavenging so close to town brings its own set of challenges to both polar bears and the people of Kaktovik. With a steady stream of tourists and scientists coming to view and study the polar bears year after year, bears grow increasingly accustomed to interaction with humans—the most dangerous predator on the planet.」2月23日 20時38分
