The Botany of Desire , a documentary film based on Michael Pollan's book argues that people have a desire to experience beauty, and that by being especially good at satisfying this desire, one flower, the tulip, has spread itself around the world.
Working in his garden one day, Michael Pollan hit pay dirt in the form of an idea: do plants, he wondered, use humans as much as we use them? While the question is not entirely original, the way Pollan examines this complex coevolution by looking at the natural world from the perspective of plants is unique. The result is a fascinating and engaging look at the true nature of domestication.
In making his point, Pollan focuses on the relationship between humans and four specific plants: apples, tulips, marijuana, and potatoes.
