The Frozen Ark is a charitable frozen zoo project created jointly by the Zoological Society of London, the Natural History Museum and University of Nottingham. The project aims to preserve the DNA and living cells of endangered species to retain the genetic knowledge for the future. The Frozen Ark collects and stores samples taken from animals in zoos and those threatened with extinction in the wild, with the expectation that, some day, cloning technologies will have matured sufficiently to resurrect extinct species. The Frozen Ark was a finalist for the Saatchi & Saatchi Award for World Changing Ideas in 2006.
