Remember the WWF "hot water" cups that were given away at the important United Nations Climate Change Conference in Bali last December? You poured hot water in them and the the graphic of the world’s land mass vanished under the rising sea.
The Miami ad school kids (in Brazil) just did their own hot-coffee version (and imply that it will be/was seen at Starbucks) for the Natural Resources Defense Council. Here we're not vanishing the earth under water, but turning continents into deserts.
One way to make two similar points. Also similar - the clever LIAA 2007 Gold Ambient indoor winner "paper towels" for WWF.
The Miami adschool credits claim that their cup was released 2007 - just like the WWF cups.
