MELBOURNE, AUSTRALIA - DECEMBER 13: The city of Melbourne is seen blanketed in thick smoke from bushfires burning in the Gippsland and Alpine regions, December 13, 2006 in Melbourne, Australia. Some thirty-seven bushfires, thought to have been sparked by lightning, have joined together to become 15 large fires. They have burnt approximately 90,000 hectares of scrub and forest and continue to spread in the southern Australian state of Victoria. Several villages and properties are under threat from the advancing fire front. (Photo by Robert Cianflone/Getty Images)
