We only have a few percent more food production than humanity needs, if I remember correctly. Roundup and other pesticides combined with fertilizer increased yields ... it doubles and triples them, and it prevents famines resulting from sudden insect plagues, which were common (as in every 30 years on average) for most of human history.
If these numbers are even close to accurate, eliminating roundup and modern farming would kill BILLIONS of humans.
I would love to get more accurate numbers, but what do you intend to do about the little "humans need food" issue in general ?
As i understand it, there are new intensive organic farming techniques that are practically unknown to big ag and which produce similar yields with higher quality (by not destroying soil and ecosystems every year). I'd counter that the final death toll of Roundup and similar chemicals could be much higher any potential famine caused by abrupt cessation of pesticide treatments. Destruction of ecosystems is an externality which has never been accounted for, and sooner or later someone will pay that bill.
