Eco-Libris, a wonderful program where you can balance out the books you read by planting a tree, is offering a way to offset your purchase of the new Harry Potter.  Send them a picture of you posing with a copy of any of the HP books, and you will get a chance to have trees planted in your name.  The first fifty entries will get trees planted in their name:  seven trees, one for each book.  Then the best picture will get a free copy of the newest Harry Potter printed on 100% recycled paper.
