"...the book maps this story. Our protagonist is farmed salmon, but as it emerges in the form of a little house sparrow that actually turned salmon, the color.
[DFP]: This is a real story that we heard about on the Isle of Skye, a sparrow whose feathers turned from brown to pink...
[AS]: It kickstarted our investigation—a kind of molecular thread that we pursue across the pages of the book, from Mexico to Norilsk, through species of all sorts.
[DFP]: In a healthy ecosystem, wild salmon eat shrimp and krill— these tiny organisms gift salmon their distinctive pink hue. In salmon farms, disrupted ecosystems, salmon would not naturally turn pink—they would be gray. And so color is artificially fed to them, according to a color-chart called the SalmoFan."
