Paper
The quantity of paper consumed by the judicial and legislative branches of the federal government is unknown, but if they use as much as the executive branch, then the federal governments total consumption would roughly equal the amount of paper produced through commercial logging on national forests annually. ( More than one-third of the timber cut on national forests from 150,000 to 250,000 acres each year goes into paper products. )

100 million trees per year are needed to produce junk mail. It is estimated that 44% of the junk mail is never opened or read.
