Well, really, we already can feed billions. Of the 1.88 billion bushels of wheat produced in the USA in 2018, only 36% was consumed domestically. We also produced about 1.1 billion metric tons of corn last year; 14% was exported, and 96% of the remainder's domestic use was feed grain. We also produce about 20 million tons of potatoes annually, half of which is sold for processed foods and feed. If we produced more wheat, potatoes, and oats, and used it all for food, we could feed several billion people just from existing US farmland.
