That one is simple. I hate this term. Its called paper or a book or magazine. In fact while we typically make ours out of renewable fast growing wood it can also be made of renewable cotton,unlike say a computer which is made of non renewable materials and which uses electricity on an enormous scale if you include Google and the other data centers that keep the Internet running.
Now don't get me wrong I am quite happy to take advantage of the benefits of PDF publishing but its not morally superior to print as the term dead tree suggests. Its its own thing with its ups and downs.
