Bury your books under a tree. With less printed material books, newspapers, catalogs etc, fewer trees will be needed by publishers, but let's not forget the plants that will still be needed to convert CO2 to O2 to keep us all alive.
Plants benefit from our carbon footprint and from your books. Come to think of it, when you bury your books, toss in an oxygen tank before you cover them up.
Your elm will thank you.
