When personal computers first began showing up in offices around the world, people believe

d that this business tool would lead to something called the "paperless office." This was hailed as a great advance in business practices.

The "paperless office" theory went something like this: people would store their information on disks and computers instead of using file folders and paper. As a result, paper use would decrease. This was supposed to help preserve natural resources as well as reduce the world's solid-waste disposal problem.

In some ways this theory has played out in practice. In offices everywhere around the world, files and records are increasingly being stored electronically rather than on paper. But the prediction has not proven to be entirely true. Documents are often printed out in part or in their entirety in order to be reviewed or shared with others. Often multiple versions of a document go through the printout stage, thus actually increasing the use of paper for each document rather than reducing it. In addition, computers have made it easier to generate notices and flyers, of which people readily make multiple copies to distribute to as wide an audience as possible. In some ways, computers have made it easier than ever before to use large quantities of paper.

So, while computers have reduced paper use in some areas, they have increased it in others. The issue of felling forests in order to manufacture paper and the question of how to dispose of so much solid waste still remain problematic.
