WWF WWF has long been famous for its original approach to campaigning. Surely, many people remember the
black cloud and
“It's not too late” .
Now, WWF has made a promotion that will not only help reduce the harm done to nature, but also make you smile. The World Fund decided to fight not the consequences of deforestation, but the causes. In their opinion, the main threat to trees are printers, devouring paper in large quantities. Or rather, their users, i.e. we are with you.

To do this, they created a special file format (.wwf extension) - which is almost the complete equivalent of PDF, but without the ability to print documents.
You can read more about the format and download the software to use it on the specially created website
www.saveaswwf.com (a version is
currently available for Mac OS X 10.4+ users, but they promise to post versions for other OS soon).
“About 13 million hectares of forest disappear every year - this is the area the size of Greece” - are upset in WWF - “Every tree is an important part of the habitat for plants and animals, such as orangutans, elephants, birds, etc. year increases the number of endangered species of fauna and flora. The WWF format, which will be gaining popularity every day, will reduce this enormous damage to the ecology of our planet. ”
Let's hope that such an unusual move will make people think!
