Media technologies have always been decisive for the epistemic registers and imaginations humans create and associate with nature. In his essay, media scholar Adam Wickberg outlines ​​how knowledge about the environment and media technologies ​have always ​evolve​d​ in tandem​; the history of anthropogenic markers can therefore be understood as a process of environing media. Getting us from the chemical composition of the atmosphere to pre-Columbian Amazonia to the rise of computational media in the late twentieth century, Wickberg chronicles and illustrates how anthropogenic markers are now a subset of a generically mediated planet.
