Mammoth Book of Apocalyptic SF 

The last sixty years have been full of stories of one or other possible Armageddon, whether by nuclear war, plague, cosmic catastrophe or, more recently, global warming, terrorism, genetic engineering, AIDS and other pandemics. These stories, both pre- and post-apocalyptic, describe the fall of civilization, the destruction of the entire Earth, or the end of the Universe itself. Many of the stories reflect on humankind’s infinite capacity for self-destruction, but the stories are by no means all downbeat or depressing — one key theme explores what the aftermath of a cataclysm might be and how humans strive to survive.
