In Susan Jeffers' "Brother Eagle, Sister Sky," Chief Seattle reflects on the profound changes that humanity's actions bring to nature and Indigenous life. He expresses a deep concern for the future of his people and the natural world, questioning the fate of the buffalo and wild horses as they face extinction. Seattle paints a vivid picture of a landscape transformed by human presence, filled with fear about losing the sacred elements of nature.

The Chief warns that the loss of these natural treasures signifies a shift from a life of abundance to one of mere survival. He mourns the disappearance of the thicket and the eagle, symbolizing the destruction of a rich, vibrant culture intertwined with nature. His poignant message serves as a call to recognize the impact of industrialization and to cherish the connection between humanity and the environment.
