Today we have a story about the sometimes obvious but sometimes sneaky effects of the way that we humans rearrange the elemental stuff around us. Reporter Avir Mitra brings us a story about how one man's relentless pursuit of a deep truth about the Earth led to an obsession that really changed the very air we breathe. This episode was reported by Avir Mitra, and produced by Matt Kielty, Becca Bressler, Rachael Cusick, and Maria Paz Gutiérrez. Special thanks to Cliff Davidson, Paul M. Sutter, Denton Ebel, and Sam Kean. Support Radiolab by becoming a member today at Radiolab.org/donate.
