Farming is the world's greatest cause of environmental destruction - and the one we are least prepared to talk about. We criticise urban sprawl, but farming sprawls across thirty times as much land. We have ploughed, fenced and grazed great tracts of the planet, felling forests, killing wildlife, and poisoning rivers and oceans to feed ourselves. Yet millions still go hungry.

Now the food system itself is beginning to falter. But, as George Monbiot shows us in this brilliant, bracingly original new book, there is another way.
