What Is the Haber Process and Why Is It Crucial for Food?

TL;DR

The Haber process is essential for food production because it converts atmospheric nitrogen into ammonia, enabling the mass production of fertilizers. This chemical reaction supports the growth of crops necessary to feed the global population, which has surpassed 7 billion. While the process has boosted agricultural productivity, its overuse has led to significant environmental issues, highlighting the need for sustainable alternatives.

What would you say is the most important discovery made in the past few centuries? Is it the computer? The car? Electricity? Or maybe the discovery of the atom? I would argue that it is this chemical reaction: a nitrogen gas molecule plus three hydrogen gas molecules gets you two ammonia gas molecules. This is the Haber process of binding nitrogen ...
