"Then, in 1909, German chemist Fritz Haber successfully fixed atmospheric nitrogen in a laboratory.[6][7] This success had extremely attractive military, industrial and agricultural applications. In 1913, barely five years later, a research team from BASF, led by Carl Bosch, developed the first industrial-scale application of the Haber process, sometimes called the Haber-Bosch process.[8][9]" https://en.wikipedia.org/wiki/History_of_the_Haber_process https://en.wikipedia.org/wiki/History_of_the_Haber_process First extraction was 110 years ago, then it was industrialized 106 years ago. That means they are out for "anybody in the last hundred years" just barely. It's amazing to think of how much change they enabled in the last 103 years. Roughly as I understand it Haber-Bosh process enabled us to get to the billions (e.g. 1B & 2B). Norm Borlaug, & the green revolution which he helped start, built on top of fertilizer & enabled the next couple billions. https://en.wikipedia.org/wiki/Green_Revolution https://en.wikipedia.org/wiki/Green_Revolution Norm Borlaug is credited with saving over a billion people from starvation & famine.
