307 - Richmond, Virginia - “Holy River” 

The James River is the reason for Richmond’s existence, and yet, in the 1970s it was one of the most polluted rivers in the country. We meet the activists and scientists who transformed it from a D- to a B+ with hard work, perseverance and art. We are also introduced to the Atlantic Sturgeon - the amazing fish that survived the meteor that killed the dinosaurs but was almost wiped out by humans.
