The barrens quest (1996)

This feature documentary examines the destruction of the tundra barrens of northern Canada for mineral mining, including that of Canadian diamonds. Many species have been threatened by this development, including the caribou and the Eskimo Curlew, a bird that flew the sky in thousands which is now nearly extinct. This film makes a compelling case for planned conservation in one of the last unspoiled wilderness regions left in the world.
