Printing documents to read them is very expensive and it also harms our environment. Americans use 700 trillion sheets of copy paper each year, (that is about 10,000 sheets per office worker!).  Every ton of paper not printed will save about 17 trees. http://www.epa.gov/wastewise/wrr/factoid.htm   Deskjet Ink costs as much per ounce as gold, The Enquirer , July 25th, 2005.  To calculate how much you can save by printing less see: http://www.epa.gov/wastewise/pubs/wwupda11.pdf
Potential savings of US$1700 per worker per year just by printing less.
Envirowise, a UK government agency, shows how a small company with 40 employees saved £40,000 a year simply by minimising paper use and wastage. http://www.envirowise.gov.uk/envirowisev3.nsf/key/dbry4phjru
