Given that every 4 minutes an area the size of a soccer game field is deforested, organization SOS Mata Atlantica has to work continuously to make people conscious. In order to talk with internauts, we have developed a banner that is entirely green. As you scan the green area with your mouse, the green will vanish gradually. In this way we are able to show, both directly and didactically, that if we dont do something, the green of our forests will also vanish.
