In the mountains of rural West Virginia, it’s a modern day gold rush. Breakthroughs in technology are allowing gas companies to tap a resource hidden deep in the earth, but at what cost? In this episode of Journey OnEarth, we're in Wetzel County to see how the Marcellus Shale energy boom is devouring precious resources locals have depended on for generations. Journey OnEarth follows correspondent Roshini Thinakaran, a National Geographic Emerging Explorer, as she reports about the people most impacted by pollution, oil spills, and toxic chemicals, as well as the communities coping with climate change across the country. BATTLE FOR WETZEL COUNTY is the 3rd installment of an 8-part short documentary series called Journey On Earth.
