Artist Maya Lin's Sound Ring immerses listeners in a world of endangered species

Maya Lin has created an art installation at the Cornell Lab of Ornithology in Ithaca, New York, to draw attention to the importance of international conservation. The Sound Ring plays the sounds of extinct, endangered and threatened species and habitats on the planet — from a chorus of lemurs in Madagascar to Weddell seals in the waters off Antarctica.
