It’s under our feet and under our fingernails, but what is it? And how did it get there? Inspired by William Bryant Logan’s acclaimed book Dirt: The Ecstatic Skin of the Earth, find out how industrial farming, mining and urban development have led us toward cataclysmic droughts, starvation, floods and climate change. Dirt is a part of everything we eat, drink and breathe. Which is why we should stop treating it like, well…dirt.
