You should take Mike Nelson's environmental economics class, he poses a similar issue to this about deforestation. Many are against deforestation and the like, claiming we are destroying our environment and natural land. The problem with this is that if we were to stop allowing new (not recycled) paper to be produced, we would also stop maintaining our "farmed" forest land and also stop planting new forests; therefore leaving less trees to produce oxygen and general appeal for our environment. High demand of paper means more trees being planted and more trees in our environment, which is good for those who are worried about deforestation.
