Urban jungle

For much of history, wild patches in cities provided essential food, fuel, medicine and places of recreation and escape for city-dwellers, and the dividing line between city and countryside was blurred. Even our post-industrial cities are much wilder places that we might imagine, with booming animal and plant populations, if we know where to look. In 'Urban Jungle', Ben Wilson explores the wild side of cities, past, present and future: the middens, abandoned sites and strips of land alongside railway lines.
