People participate in a mass floating event in the Dead Sea September 14, 2012. Hundreds took part in the event to raise environmental awareness for the ailing sea, located at the earth's lowest point. The event took place on the one-year anniversary of the day when thousands of naked volunteers posed at the Dead Sea for U.S. artist Spencer Tunick, who also attended Friday's event. The placard reads: "Stop robbing our sea". REUTERS/Nir Elias (ISRAEL - Tags: ENVIRONMENT TPX IMAGES OF THE DAY)
