I just found out about this great website/organzation called EcoLibris. They will plant trees for every book you read. It's really interesting.
I found out about it after I mooched a book from one of the co-founders and she sent me an e-mail:
"Eco-Libris, a new green biz that I co-founded that lets book readers balance out the paper used for the books they read by planting trees. Our customers also receive a sticker made of recycled paper for every book they balance out saying "One Tree Planted for this Book" and can later display these stickers on their books' sleeves.
About 20 Million trees are cut down annually for virgin paper used for the production of books sold in the U.S. alone. What we want to do is to raise awareness to the destructive environmental impacts of using paper for the production of books and provide people with an affordable and easy way to do something about it.
We have partnered with three highly respected US and UK registered non-profit organizations that work in collaboration with local communities in developing countries to plant the trees. These trees are planted in high ecological and sustainable standards in Latin America and Africa, where de forestation is a crucial problem, and planting trees not only helps to fight climate change and conserve soil and water, but also benefits many local people, for whom these trees offer many benefits and an opportunity for a better future."
It sounds like a really great project! Check it out!
