Taking Root: The Vision of Wangari Maathai: This documentary provides a window into the extraordinary life of activist and Nobel Laureate Wangari Maathai, a Kenyan woman who has worked to regain ownership of her country and its fate after years of colonialism. While gentle and thoughtful, Maathai carries a powerful message: the First World holds much of the responsibility for the environmental, economic and social struggles of the developing world.
