Books are made of paper, which comes from trees, so why not plant new trees to offset the environmental impact of the books you buy? This greening of books is the idea behind the Eco-Libris website. True, it doesn't offset the energy and water resources required to produce the paper pulp and transport the finished product to the store, but it's very cool to slap on a sticker that says, "A tree was planted for this book." And yes, the stickers are printed on recycled paper using non-toxic inks.
