Buying Books to Sequester Carbon
Carbon footprints have always looked more like superstition than science to me, especially when the estimates differ by a factor of 30 or so. In the case cited, much of the calculation seemed pretty dicey - the carbon cost included the carbon incorporated in the book plus the carbon that the tree cut down might have taken from the atmosphere in the future.
Oh please! Trees grown for fiber are going to be cut down sometime and wouldn't live forever anyway. Also, they will be replaced by new trees that will in turn grow and take up carbon, and the carbon taken from the tree is now a durable book.
Of course I now buy most of my books in electronic form.
