Earth Matter delves into the history of extractivism in Chile, beginning with the nitrate mines in the Atacama Desert in the nineteenth century and extending to the ongoing extraction of copper, lithium, and water. Through photography, video, archival research, and personal interviews, artist-researchers Xavier Ribas, Ignacio Acosta, and activist-writer Louise Purbrick examine the interconnected forces that bind Chile's natural resources to global capital, particularly in the financial district of London.
