I’ve edited this wisdom to be more accurate:
Despite all our accomplishments, all 7 billion of us owe our existence to a six-inch layer of topsoil and the fact it rains; and 6 billion of us also owe our existence to Haber-Bosch.
This invention, by far, has had the biggest negative impact on our planet.
Had Haber-Bosch been used with birth control it would have been a mostly positive invention.
I wrote a book review on the biographies of Haber and Bosch here.
