Who is Danny Forsyth, Steve Young, and Mike Heath from The Botany of Desire and what is their importance?

The three named individuals are all Idaho potato farmers, and all three offer extensive interviews to Pollan. All three men are likable, credible and hard-working individuals. Two, Forsyth and Young, practice modern agribusiness farming—one, Heath, practices organic farming. Heath's farm yields nearly as many potatoes per acre as Forsyth's and Young's farms, but the potatoes are not the monoculture Russet Burbank, which American consumers demand.
