WWF, the international non-governmental organization made this rare poster for the Copenhagen Summit in December 2009. During that summit the world leaders met to discuss Climate Change. WWF launched an intitiative called Vote Earth! to mobilize people to vote and put pressure on the world leaders to make the right decisions. They’ve created a poster entirely made of ice that was placed in a central spot of Lisbon. The poster warned of the consequences of the ice-cap melting, making people feel the urgency of putting an end to environmental disasters.
