Your Call: What does the air we breathe tell us about our history?


In his new book Caesar’s Last Breath: Decoding the Secrets of the Air Around Us, science writer Sam Kean writes that with every breath you take, you inhale the history of the world.

Kean reveals how the alchemy of air reshaped our continents, steered human progress, powered revolutions and continues to influence the world around us. From nuclear warfare to global warming, how has the history of our planet shaped every breath we take?
