Safe as WWF and safe a tree.The World Wildlife Fund  has created a new, PDF-type file format called WWF. It’s a file format that can not be printed out.

The foundation for the conservation of nature is in full campaign to prevent the massive cutting of trees for paper production. As can be heard in the ads they have prepared for the occasion, millions of trees are cut down every day to make paper. This is a massive problem they  aim to reduce.

Decide for yourself which of your documents don’t need printing and save them as WWF. The WWF format is a PDF that cannot be printed out. It is now so simple way to avoid unnecessary printing. So here’s your chance to save trees and help the environment.
