Kate with William Bryant Logan

Topic: William Logan’s book Air.
Air sus­tains the liv­ing. Every crea­ture breathes to live, exchang­ing and chang­ing the atmos­phere. Water and dust spin and rise, make clouds and fall again, fer­til­iz­ing the dirt. Twenty thou­sand fun­gal spores and half a mil­lion bac­te­ria travel in a square foot of sum­mer air. The chem­i­cal sense of aphids, the ultra­vi­o­let sight of swifts, a newborn’s aware­ness of its mother’s breast—all take place in the medium of air.
