Eco-Libris

Description: About 20 million trees are cut down annually for virgin paper used for the production of books sold in the U.S. alone. That's definitely a problem--trees are a valuable natural resource. They literally form the foundations of many natural systems and provide numerous benefits (carbon dioxide absorption, soil and water conservation, avalanche control, desertification prevention to name a few). Eco-Libris provides a simple and affordable way to do something about it. Plant trees for books.
