After leaving a career in science, Subhankar Banerjee spent 14 months documenting the Arctic National Wildlife Refuge, producing photographs that became the defining visual record in the campaign against oil drilling. His 2003 Smithsonian exhibition sparked political controversy after the Bush administration intervened to limit its display, while senators entered his images into the Congressional Record during debates over Arctic conservation. Banerjee demonstrated how photography could shape environmental policy and public opinion at the highest levels of American government.
