The mission of the What is Missing? Foundation is tocreate, through science-based artworks, an awareness about the current crisis surrounding the mass extinct ion of species that is now underway. The project will connect this loss of species to its primary causes- habitat degradation and loss. What is Missing? is both a wake up call and a call to action- creating innovative artworks that utilize sound, media and science to connect people to both the species and places that have disappeared or will most likely disappear if we do not act to protect them. First making us aware of this crisis, the project will thenhighlight what environmental organizations, institutions, and scientists around the world are doing to find solutions to the extinction crisis and the overarching threat of climate change. The project will also show what individuals can do in their everyday lives to help protect species and the habitats that species depend upon for survival. Designed as Maya Lin's last memoriaL the project proposes that we look at a memorial not as a singular static object, but as a work that can exist in multiple forms and in multiple sites simultaneously. The Memorial will consist of media and sound works that are, and will be, installed at permanent and temporary sites throughout the world. These installations will feature one-to-two minutes films produced by the Foundation, which focus on species and habitat loss around the world. Over 75 films have been created to date, with plans to develop a library of 150 videos for use in schools and institutions for educational purposes. The installation formats include: permanent Listening Cones placed at select science institutions, an Empty Room exhibit that can traveL smaller site specific sound and media installations, to art, science and public venues, independent video works that can be shown at events, a physical and digital book, and a website that acts as a nexus for the project in its entirety and enables people to navigate through time, revealing an ecological history of the world by virtue of maps of the past (Map of Memory), present (Conservation in Action), and future (Greenprint).
