Freeganism is a practice and ideology of limited participation in the conventional economy and minimal consumption of resources, particularly through recovering wasted goods like food. The word "freegan" is a coinage derived from "free" and "vegan". While vegans might avoid buying animal products as an act of protest against animal exploitation, freegans—at least in theory—avoid buying anything as an act of protest against the food system in general.
Freeganism is often presented as synonymous with "dumpster diving" for discarded food, although freegans are distinguished by their association with an anti-consumerist and anti-capitalist ideology and their engagement in a wider range of alternative living strategies, such as voluntary unemployment, squatting abandoned buildings, and "guerilla gardening" in unoccupied city parks.
Freegans' goal of reduced participation in capitalism and tactics of recovering wasted goods shares elements with the Diggers, an anarchist street theater group based in Haight-Ashbury in San Francisco in the 1960s that organized free housing and clinics and gave away rescued food. The word "freegan" itself was allegedly invented in 1994 by Keith McHenry, the co-founder of Food Not Bombs—an anarchist group that distributes free vegetarian meals as a protest against militarism and as a way of providing "solidarity not charity"—to refer to vegans who eat animal products if they find them in a dumpster. McHenry's account is consistent with other published accounts of freeganism that show the word as beginning to be used in the mid-1990s by participants in the antiglobalization and radical environmental movements.
The pamphlet "Why Freegan?"—written by former Against Me! drummer Warren Oakes in Gainesville, Florida in 1999—defines freeganism as "an anti-consumeristic ethic about eating" and goes on to describe practices including dumpster diving, plate scraping, wild foraging, gardening, theft, employee scams, and barter as alternatives to paying for food. The pamphlet also expanded the activities associated with "freeganism" with a long section on non-alimentary practices, including conserving water, pre-cycling, reusing goods, and using solar energy. More than just a set of behaviors, though, the pamphlet presents freeganism as having an overarching political goal: an "ultimate boycott" of "all the corporations, all the stores, all the pesticides, all the land and resources wasted, the capitalist system, the all-oppressive dollar, the wage slavery, the whole burrito" in favor of "liv[ing] a full satisfying life...while treading lightly on the earth." The first organized group of self-described "freegans" formed in 2003 as an offshoot of the Wetlands Preserve nightclub and associated Activism Center in New York City. According to the group freegan.info, "After years of trying to boycott products from unethical corporations responsible for human rights violations, environmental destruction, and animal abuse, many of us found that no matter what we bought we ended up supporting something deplorable. We came to realize that the problem isn’t just a few bad corporations but the entire system itself." From 2005, freegan.info organized regular events including sewing and bicycle workshops, wild food foraging expeditions, and "trash tours"—public dumpster dives open to the public and to media.
