Re-read the piece and try to pay attention, Erik! By nearly all sane estimates, the pre-Haber Bosch earth could only feed <3 billion sustainably and naturally.

You project racism if you're accusing me of even bringing up eugenics. I'd be offended... if the premise of the accusation wasn't so stupid. ;)
