"These four posters each have hidden images--human faces peering out of the jungle. They are from the World Wildlife Fund Brazil&amp;#039;s &amp;quot;Preserve the World, Preserve Yourself&amp;quot; campaign. The message is clear: our survival depends on how well we manage the world we live in. The faces show a range of expressions, from sad and weeping to anger and even disgust. Telling images indeed of what we are doing to our environment.  Some of the translated Portuguese words on the posters include this message: &amp;quot;The solution for the global warming isn&amp;#8217;t buying an air conditioner.&amp;quot;"^^<http://www.w3.org/2001/XMLSchema#string>
