As the oil giant Shell prepares to begin exploratory drilling in the Arctic, activists across the world have begun holding protests. The Obama administration has set a deadline for next month to decide on whether to grant the final drilling permits. Over the last decade, Arctic Alaska has become the most contested land in recent U.S. history. But in addition to oil, natural gas and coal, the Arctic is rich in biodiversity and has been home to generations of indigenous people for thousands of years. We’re joined by Subhankar Banerjee, a renowned photographer, writer and activist who has spent the past decade working to conserve the Arctic and raise awareness about human rights and climate change. Banerjee is editor of the newly published book, “Arctic Voices: Resistance at the Tipping Point,” and has just won the 2012 Lannan Foundation Cultural Freedom Award.
