The author described nerd and geek as pretty much the same thing. He said that it was someone who likes science fiction, post punk music, comic books, and videogames. He said that Otaku is a Japanese term for obsessive, minute obsessions, especially anime and videogames. His point in saying this, was to show how him and his friends Otaku made them unique. The "nerdy" activities made their group unique and he really enjoyed being different. People called him and his friends nerds and geeks, but that only bonded them closer together. They enjoyed certain things that no one else at the time did, and it made their group of friends very close and they hung out because of the unique interests they had. Then technology and the media came along and made the nerds interests mainstream and no longer unique. This showed how society follows the crowd and will go from calling someone a nerd to "wearing a Boba Fett sleeveless shirt at the gym". When movies started to become very popular, things such as comic books and unbelievably long books (Lord of the Rings), became mainstream. This disappointed the author very much because it made his Otaku disappear. Geekiness became normal and there is now nothing separating him from any everyday person. 

Supermarket pastoral was defined as the act of getting food from animals that are treated humanly. Pollan was a huge organic food enthusiast that buys his food from organic supermarkets. Despite being more expensive, Pullan was willing to pay the extra money to ensure that he was buying food from a moral supermarket that treated animals well. He was very impressed that all the milk he bought was from cows that lived a very comfortable, stress-free life. By buying from this supermarket, he felt like it gave him a connection to earth and the creatures that we depend on for food and milk. He likes how the supermarket he buys from is seen as the "good guys" which is composed of the American family farmers. This is opposed to the businessmen who are villians that treat the animals poorly and use them purely for profit.  In Pollan's opinion, organic cultural is the right way to treat animals. They are treated as well as, if not better, as humans and makes sure that they live a comfortable life. His theory is that we rely on animals for food and milk and that we should treat them with respect and let them live a very comfortable life as they help us humans thrive.
