First of all, +1 Tr.
Second of all, as bad and unnatural as the Haber Process is, the fact of the matter is that we discovered it and Borlaug's work showed one of the ways that it has the potential to be used for the good of humanity. Whether that's good for the world - well, no, it's not, but I don't support a cull, so feeding the people that we have is essential, and that's what modern agriculture is all about.
Third of all, your words are insensitive and tasteless at best. This is what you said:
"Feeding poor people in 3rd world nations doesn't strike me as overly affecting the course of human history."
Do you actually think that saving a billion lives is unimportant in the course of *human* (read as "people," not white Westerners) history? Is Aristotle somehow greater in the course of human history because he wrote down a bunch of cool stuff - that, by all means, he is deserving of a fuck ton of credit for - than Borlaug, whose work is both practical (it feeds you too, not just those damned poor people in the part of the world too depressing for you to bother thinking about, and if you have any stake in the agriculture industry, it provides you your livelihood) and insanely impactful?
Your idea of "human" is appalling, insensitive, tasteless, and utterly terrible if you don't think that "poor people in third world nations" isn't "overly affecting" human history, as if to say that they have little right to consider themselves a part of human history in the first place.
Here you go.
