It's no secret that agriculture in the U.S. has gone through major changes in the past century. But let's focus in on ag labor for a second: back in 1900, 41 percent of the national workforce worked in the agricultural sector. By 2000, just 1.9 percent did, according to the U.S. Department of Agriculture (USDA). Over the same time period, millions of residents left rural communities behind, seeking job opportunities in cities.
