In the past century, several unique species were driven to the brink of extinction, and others; into the memories and records of past generations. Thylacine, Black Rhino, Laughing Owl. Even the Eastern cougar was officially ruled extinct in 2011. Dozens of mammals and birds, seen to the children of today, in no other form than artworks, and taxidermy.
I propose; that the technology used for Holographic recreations of musicians, be put to better use, and used to create full-sized, three-dimensional projections, of famous extinct species. The sight of these creatures lost, may help conservation. A simple Smithsonian Exhibit, could change so much.
