[3> Why does he have to account for livestock? That has nothing to do with the argument he's responding to. Actually it does. 90 million acres of corn were planted for livestock in 2018 [0] and we know that the nutritional density of corn has declined [1]. So the long term is we just keep yielding higher with lower nutritional value? The main reason we're after higher yields is livestock and mass produced "junk" food which provides what positive value? The sustainability problem aside, how does this benefit us globally and long term? > Statistically, is vitamin deficiency a serious public health problem in America? Is it a problem? Yes. [2] In America? Past studies [3] have shown this and I don't think it's a stretch to just look at the health epidemic here which is, generally, systemic from poor overall nutrition. [4] Sure, the productivity factor is in our "favor", at least by the numbers. But it's very clear that there is negative impact that extends beyond just the yielded nutritional value. It flows down into additional consumption and requirements to fortify nutritionally sparse natural ingredients.
