It seems an irrefutable truth that raising animals for meat has become unsustainable. Land is being eroded and destroyed, water resources overdrawn, greenhouse gases over-emitted, and energy and crops unnecessarily diverted - all to satiate a growing and inequitable global overconsumption of meat. But is all meat unsustainable? Sustainable food systems are multiple and varied and represent the diversity and complexity we see in the world. Green Meat? teases out some of that complexity in order to consider what roles animals and their products might play in the future as the world works towards new ways of living.
