Writer Michael Pollan Writer Michael Pollan. His book, The Botany of Desire: A Plant's-Eye View of the World takes a look at four plants cultivated by humans: the apple, the tulip, potatoes and marijuana. Pollan demonstrates that plants and humans have developed a reciprocal, co-evolutionary relationship: do we plant potatoes, or do potatoes seduce us into planting them? Pollan questions the assumption that we are in charge of our agriculture. The book is now in paperback.
