The issue “Ecological Histories of Photography” examines the relationship between photography and ecology as understood in multiple ways: ecology as an interdisciplinary science which has sought a global understanding of the environment since its emergence in the 19th century; ecology as a specific agenda within political and activist movements that emerged with the rise of public awareness of environmental issues in the second half of the twentieth century; ecology as the object of social and philosophical movements which question the binary opposition of nature and culture in Western society; and finally the ecological impact of the photographic industry through its dependence on extraction, petrochemical derivatives, and more recently digital technologies.
