As part of the global 'rights to the city' movement and mounting concern over food waste, results are presented here of an ethnographic study of young people in Australia who choose to glean food from supermarket 'dumpster bins' and open markets primarily for political reasons. These youth form part of an international 'freegan' subculture: the belief in 'minimising impact on the environment by consuming food that has literally been thrown away' (Macmillan English Dictionary Online 2002). The study explores the emergence of two related subcultures: 'Dumpster Diving' (the act of procuring food from a supermarket dumpster bin for individual consumption) and 'Food Not Bombs' (a global-spanning group who collect left-over food from markets to cook and serve to people on the street). The analysis focuses on the ethics embedded within their alternative consumption diets. These findings are analysed in terms of the creation of their alternative identities performed on temporal-spatial terrains, exemplifying the role of the contemporary activist's use of space, place and culture in relation to social issues.
