Book excerpt: We see the signs around us every day: the chain cafs and mobile phone outlets that dominate our high streets; the disappearance of knobbly carrots from our supermarket shelves; and the headlines about yet another traditional industry going to the wall. For the first time, here is a book that makes the connection between these isolated, incremental local changes and the bigger picture of a nation whose identity is being eroded. As he travels around the country meeting farmers, fishermen and the inhabitants of Chinatown, Paul Kingsnorth reports on the kind of conversations that are taking place in country pubs and corner shops across the land - while reminding us that these quintessentially English institutions may soon cease to exist.
