How can media studies save the planet? This bold question motivates research within the emerging framework of materialist media ecology. While the term ‘media ecology’ has been applied since the 1960s to the study of media as metaphorical environments, it is only in the past decade that media scholars have started to realise, and begun accounting for, the material, ecological cost of media consumption, especially in its current electronic forms. In addition to the palpable materiality of media-technological hardware and its waste streams, materialist media ecology also concerns itself with the infrastructures and carbon emissions associated with producing and transmitting the signals that enable contemporary connectivity.
