People write on a police sign as they  demostrate while take part in the Global Alternative Forum for Life and Environmental Social Justice in Cancun
People draw on a police banner at a protest during the Global Alternative Forum for Life and Environmental Social Justice in Cancun December 5, 2010. The United Nations climate change talks in Cancun have far lower ambitions than last year's Copenhagen summit which fell short of an all-encompassing deal to help slow floods, droughts, heatwaves and rising sea levels. The banner reads, "Federal police check point, 300m". REUTERS/Gerardo Garcia (MEXICO - Tags: ENVIRONMENT DISASTER CIVIL UNREST POLITICS)
