Problem
What does Richard White mean by "organic machine," and why does he apply the term to the Columbia River? In other words, what, exactly, makes it an "organic machine?" Secondly, compare and contrast how Native American societies and white societies have historically used the river. What functions has it served in their economies and even cultures? Finally, discuss some of the unintended consequences of the river's "modification" by humans. What attempts (if any) have been made to address these problems?
