A volunteer places bones made of paper and plaster as part of the One Million Bones art installation on the National Mall near the U.S. Capitol in Washington, June 8, 2013. Organizers said the project, led by artist Naomi Natale, mobilized artists and students around the world to create the bones in order to bring attention to genocide and mass atrocities.
