But all paper making is immensely polluting, and I'd be willing to be your average tree farm is not friend to the environment, either. And in my version of a bookless future, reading would not require special devices like the Kindle but rather involve a contraption that would serve many other purposes as well, i.e., a run-of-the-mill computer (obviously lighter and more portable than laptops are currently, but that's bound to come), which people would be buying, upgrading, etc., regardless.
