Final answer:
LaDuke argues that modern reliance on technology has caused a loss of traditional navigation skills, using personal experience and logical reasoning to establish credibility and appeal to the reader.
Step-by-step explanation:
Winona LaDuke in the passage "A Case for Waawaatesi" is making a point about the loss of traditional navigation skills due to over-reliance on modern technology like GPS, and how this loss is more pronounced in urban areas with light pollution obstructing the view of the stars. LaDuke establishes credibility by mentioning personal observations from her farm, appealing to the reader's sense of heritage and the concrete example of light pollution's impact. The writer uses logical reasoning to connect the loss of these skills to the inability of urban dwellers to see the stars, suggesting a disconnection from indigenous and rural ways of living that remain closer to nature.
