The Haber-Bosch process, which originated in Germany at the beginning of the 20th century, was heralded as "bread from the air" and significantly improved agricultural production.

This is a technology for synthesizing ammonia, an invention that, roughly explained, "makes crops ten times better than conventional ones.

This invention was supposed to end the paradigm of "wars over territory to compensate for food shortages.

What would have happened if the Haber-Bosch ammonia production equipment could have been left behind in Japan's Warring States period?

At least it eliminates territorial ambitions with food. Still, it doesn't get us out of the paradigm that "rice cultivation strengthened the status system" after all -- not much has changed.

Increased food production would only lead to an increase in population, which would lead to strategic wars outside the country in search of land for crops -- and, well, that's what I was thinking.

If Fritz Haber had stopped there, he could have left his name in history as a savior of humanity, but he later developed poison gas as a weapon. The anti-Jewish movement of Nazi Germany finally forced him out of his country, leading to his untimely death and leaving his name in disgrace.

What I'm trying to say is,

We should not do research for "honor" or "justice."

If you do it anyway, I think it is better to do it around "interest" and "entertainment."
