What metaphors are used in The Everglades: River of Grass by Marjory Stoneman Douglas?

When the various Indian tribes arrived, they adapted their customs and culture to the environment of the Everglades. They didn't try to change the Everglades. The Indians just adapted to the environment they were in. This wasn't true of the white man as Florida became more settled. They tried to change the Everglades. They dug canals and tried drainage of the swamplands, thinking they could use the lands for other purposes. This becomes a metaphor for "civilization" which ironically meant destruction of the ecosystems.
