Changed your light bulbs, gone vegetarian, sold your car, but still feel like your consumer impact is intolerable? It may be time to go freegan and learn to live off the waste that others throw out. Freegans gain most of their possessions and sustenance by foraging — for clothes, for furniture, and for grocery-store food that is slightly bruised or just past its expiration but still entirely edible.
