Books play a big role in our everyday education, but the book making process plays a big role in pollution. Manufacturing book pages requires large amounts of wood, water and chemicals, and releases harmful emissions into the air around us. That's why buying used books is a smart move. The Dickson Street Book Shop in Fayetteville sells only used books. "There's just thousands and thousands of books out there so why not recycle them? We kind of help be the middle man there for people to do that," says store employee Mariah Smith. The store has more than 100,000 titles lining their shelves from floor to ceiling. Instead of gift cards the store keeps everything on file to reduce waste. "Instead of giving people these cards that they're getting rid of, we have it all on a file system so we recycle that whole system so it creates a lot less paper there," Smith says. For the past thirty years store owners and employees recycled more than just books. They recycle paper, cans and bags. So for them, being green is nothing new. "It's just what we do and what we've always done, so it's not like we're having to make a lot of changes in order to be green, it's just the system that it's always been."
