Filmed at TEDxVictoria on November 19, 2011, photographer Garth Lenz shares shocking pictures of the environmental devastation of Alberta tar sands mining projects and the beautiful and vital ecosystems they jeopardize. For almost twenty years, Garth’s photography of threatened wilderness regions, ecological destruction, and impacts on indigenous peoples has appeared in the world’s leading publications. His recent images from the boreal region of Canada have helped lead to significant victories and large new protected areas in the Northwest Territories, Quebec, and Ontario. Garth’s major touring exhibit about the tar sands premiered in Los Angeles in 2011 and recently appeared in New York. Garth is a fellow of the International League of Conservation Photographers.
