Overgrowth is an interactive environment exploring the ecological consequences of industrial agriculture through more-than-human perspectives. Species that thrive on pollution, such as nitrogen-loving lichens or ammonia-fed dandelions, populate this world deprived of human presence. Their excessive growth, while signaling abundance, is a symptom of ecological distress caused by intensive farming,over-fertilization, and emissions. Through the act of playing, Overgrowth de-centers the subjectivity of human users, as they experience the environment from the perspective of cows stuck in an exploitative and polluting system. The machines employed to improve the efficiency of agricultural processes, such as milking robots and insemination stations, become material witnesses of this multispecies suffering. By learning how to read the messages hidden in the landscape and sensing the effects of carelessness, the work prompts us to imagine new forms of multispecies relations and coexistence.
