The Alchemy of Air: A Jewish Genius, a Doomed Tycoon, and the Scientific Discovery That Fed the World But Fueled the Rise of Hitler by Thomas Hager
The Alchemy of Air: A Jewish Genius, a Doomed Tycoon, and the Scientific Discovery That Fed the World But Fueled the Rise of Hitler

Barbara Branham, January 1, 2013

A fascinating book about how the population of the world had reached a point where there would be mass starvation in the early 20th C. because farming had reached it's productivity limit. The development of a method to pull fixed nitrogen out of the air and the invention of a machine that could produce fixed nitrogen in enormous quantities allowed the world's population to reach current levels. Now, 100 years later, we face the same problem again: how to increase productivity to feed 6+ billion people.
