Yep -- when I started researching corn for my own horticultural reasons, I was cold shocked to find out only ~10% goes to feed humans, with the balance going mainly to animal feed and ethanol :

- sharkmerry 8y agoThanks for all the links. I sincerely was asking as a counterpoint, not to troll. I did know about grain being used to feed cattle, but a lot of the grain they eat is not of "human quality" so saying that we can just switch humans from meat to grain and feed 800 million people is very misleading.
- fnovd 8y agoDo you have any sources on the percentage of grain that is not of human-quality? Are there any estimates of what percentage of the non-human quality grain can be filtered to become human-quality? We're not talking about fundamentally different plants, just the difference between seeds, stalks, & husks vs seeds alone. Even putting the exact number aside, we're talking about thousands and thousands of hectares of arable land used solely to feed livestock. Even if the number is only 80 million (back in 1997), it is still a large-enough number to beg the question: is this the best use of our resources?
- sharkmerry 8y agoI've been looking but I cant find anything yet. > We're not talking about fundamentally different plants, just the difference between seeds, stalks, & husks vs seeds alone. I think it's also how its stored and # of broken kernels (for corn anyways), etc. Im not arguing against the point, was just trying to bring some perspective
- MisterOctober 8y agoI don't have a source / link handy at the moment, but a couple relevant notes to consider : 1) the vast (vast) majority of corn consumed by humans is processed into things like corn syrup, modified starch, whiskey, etc, rather than eaten "whole" as a grain [like, say, as tortilla chips or whatever], so the notion of broken kernels, etc, scarcely applies to this particular consideration -- see above-linked infographic 2) The question of what type of corn is grown is a really interesting one -- I could rattle on about this for a long time, but suffice to say that the family of varieties generally known as "Corn Belt Dent" [derived at some length from Nothstine and similar early dent corns] is designed to serve both feed / silage and processing-for-human-consumption [including ethanol] purposes. Now, this is not stuff you eat as "corn on the cob" [those are called sweet corns, though back in the day folks used to eat green Corn Belt Dent roasted as "Trucker Ears"], nor is it the same as popcorn [which is its own family, derived at length from flint corns]. There are in fact varieties designed specifically for silage [the common type of feed, where pretty much the entire plant is fermented and fed to animals; these varieties have less fibrous leaves and sometimes more leaves] and grain / processing / ethanol ['floury' types], but it's a matter of choice / market analysis from the farmer's perspective, and ye olde corn belt dent can serve both purposes if need be. one quick link re : ethanol : https://articles.extension.org/pages/27536/corn-for-biofuel-production https://articles.extension.org/pages/27536/corn-for-biofuel-...
