For a glimpse of what could happen to a trillion dollars worth of American farmland, meet Ray Williams.
He's a lawyer-turned-farmer, growing organic grain and feeding young cows on 3,000 acres in northeastern Oregon. Last year, he and his brother Tom decided that they were getting too old for the long hours and hard work.
"We told our clients, you don't want to rely on senior citizens for your high quality organic products. Trust me on this!" says Williams, age 68.
