Botany of Desire

Michael Pollan (author of Omnvivore's Dilemma) has written a wonderful book entitled The Botany of Desire. PBS has made this book into a movie that follows the book quite closely (although emitting many of the details). You can watch the movie for free at pbs.org. Click here for the link.
The book and movie discuss 4 plants that have been important throughout the history of humans: apples, tulips, marijuana, and potatoes. He talks about how these plants have evolved over time to meet human need and desires and questions us to ask if we are manipulating the plants, or if, in some sense, they manipulating us.
The book and movie discuss some interesting facts that anyone with an appreciation for nature or a love for food would enjoy. From the reproduction of apples (did you know that all apples we eat come from clones of trees and NOT from seed?), to the huge popularity of the tulip that resulted in outrageous prices for a single bloom, to the use of genetically modified potatoes and the effects that can have on ourselves and our environment. I would highly recommend this book to everyone, especially those with an interest in gardening. And, if you can't get to the book, or have already read it, this movie does a great job of discussing Pollan's big ideas.
