"The United States is one of the biggest consumers of paper in the world. Between 1990 and 2002, paper consumption in the United States increased from 84.9 million tons to 97.3 million tons." Wikipedia

Wiki is your source??

Okay.......right...sure...whatever you say..

You can get the raw data from
http://www.census.gov/prod/1/manmin/asm/m93as-1/m93as-1a.pdf (for 1992-1993)

and

http://www.census.gov/prod/2006pubs/am0531gs1.pdf

for 2002-2005, in which period usage has continued to rise.

I agree that the technology already exists to enable us to use far less paper, but paper is still way too cheap, and hence gets used very wastefully.
