Fritz Haber's Ammonia Process Transforms Global Nitrogen Supply
Fritz Haber's ammonia synthesis, initiated in 1909, now provides nitrogen for half of the protein in the human body today. This process sustains approximately four billion people, highlighting its critical role in the global food system and its environmental implications.

The Haber-Bosch process, developed by Fritz Haber and scaled by Carl Bosch, has transformed nitrogen fixation, now accounting for approximately half of the nitrogen in human protein. This reaction, first conducted in 1909, allows nitrogen from the atmosphere to be converted into ammonia for use in fertilizers, sustaining the food supply for billions.
Ammonia production, however, relies heavily on natural gas, contributing significantly to global energy consumption and CO₂ emissions. As a result, fluctuations in gas supply can directly impact food prices. Research continues into alternative nitrogen fixation methods, which could potentially reduce dependency on fossil fuels.
