I like paper even though I have a nook that I mostly use for library e-books or free e-books. I still enjoy paper and don't like it being called "dead tree edition." With proper forestry trees are a renewable resource. Electronic devices use electricity which causes pollution (unless solar/wind etc.) The creation of electronics and the disposal/recycling of electronics also causes pollution. Either way you go there is going to be an environmental impact. I think the best option would be to use your library. That way the book is getting used repeatedly. I am trying to break the habit of feeling I need to own things.
