To get to those labor efficiency numbers we've made a lot of food quality and environmental sacrifices. TFA specifically mentions automated laser weeding instead of herbicide/GMO. Fertilizer microdosing is also mentioned which would greatly help fertilizer runoff pollution. I'm sure you've heard of other problems with factory farming, many of which are labor saving practices. The cross section of farming, public health and environmental impact can't be reduced to a commodity spot price, at least not in our current economic system.
