Want Not: A Dialogue on Sustainability with Images Karen Pinkus and Cameron Tonkinwise CT: Song Dong's Waste Not is the artist's mother's house with everything that was in it during a period of the Chinese government's edict to “waste not.” 1 It captures a sense of the volume of materials over time passing through homes, what is not normally visible because we have surprisingly effective waste concealing systems. It makes apparent the absurdity of using long-life materials for short-life uses. It foregrounds capitalism (via negative socialism), but also the emerging global consumer class in China. It also points to the constipated error of a steady-state version of sustainability. Living involves flows, whereas hoarding leads to death—the piece is a work of mourning by Song Dong and his mother for his father/her husband.
