This fascinating book takes you all over the world and deep into history. It's main aim is to challenge the theory that folk societies and non western civilisations,lived in harmony with their enviroment,and that only modern western societies are the root of pollution,extinction,mass murder and social exclusion. Edgerton really slays a sacred cow here ,with a wealth of information about maladaptive customs of the native americans, africans, eskimos, aboriginals, chinese and indians, to name a few. Some of the customs he descibes are odd ,some are cruel and at times disgusting , but never boring. This book is a real eye opener and I highly recommend it to anyone
