If California were a nation of its own, it would have the twelth largest economy in the world; agriculture would be a huge percentage of it. Much of the labor that produces is done by migrant farm workers who come to the US, sometimes illegally, and follow the crops, before returning home to Mexico and places even further south. I spent some time with migrant farmworkers in California’s immense – and immensely fertile – Central Valley, and filed this report for the VOA.
