Since naturalists realized that the human activity was provoking the extinction of many species, it became a necessity and a dream to create an archive of all the living creatures on Earth. Many have tried and failed. Some like 19th-century ornithologist and painter John James Audubon were limited by the technology available at their time. Yet Audubon classified hundreds of illustrations, collected in his book Birds of America. Others, such as photographer Joel Sartore, are currently working on an archive of thousands of animals all around the world, hoping to capture the whole animal kingdom. Today, researchers are able to create accurate 3D models of living organisms to preserve the heritage of life on Earth, that’s the aim of Digital Life Project.
