Winona La Duke is a powerful and eloquent spokesperson for Indian efforts to recover the rights to their lands, as guaranteed by treaties. La Duke also fights the 'buying off' of Indian lands by the U.S. and Canadian governments that often results in the deposit of nuclear waste, strip-mining, over-irrigation and other environmentally un-sound practices. La Duke is the campaign director of the White Earth Land Recovery Program and the environmental program officer for the Seventh Generation Fund, a national native foundation.
