MORE WITH LESS

In the 1940s, one U.S. farmer produced enough to feed 19 people. By the 2000s, that number had grown to 155.

Over 200 years ago, 90 percent of the U.S. population lived on farms and produced their own food to eat. But today, only two percent of the population produces food for the world to consume.
