The Problem : A Toxic Journey
High above the Arctic Circle, polar bears inhabit some of the most remote and seemingly pristine territory on earth. Yet, scientists have discovered that these bears are highly contaminated with industrial chemicals, including toxic, long-lived PCBs. There is no way to discover exactly how the PCBs made their way to the Arctic. But drawing from historical accounts and scientific studies it is possible to imagine the path of an individual PCB molecule. Though the specific route and events in this journey are hypothetical, the plot is scientifically plausible.

Based on the chapter "To the Ends of the Earth," from Our Stolen Future by Theo Colborn, Dianne Dumanoski and John Peterson Myers
