In "Extinct", six extinct species are brought back to life using 3D computer graphic technology. With programmes devoted to the dodo, sabre-toothed tiger, great auk, Tasmanian tiger, Irish elk and mammoth, viewers can watch the story of these animals from birth. The "Extinct Fact Files" gives young readers a chance to learn more about these animals and birds. With original illustrations, maps and timelines, they can explore how and where each creature lived, how it hunted and what is was hunted by. The book explains what happened to cause these species to die out, and the impact of climate change and human interference. With countless more species balancing on the brink of survival today, the "Fact Files" provides useful information on what we can really to to help.
