This book discusses how as humans we can help promote biodiversity and strive for ecological stability through reduced mammal hunting and by maintaining food networks with carnivores at the top of the food chains. Unfortunately, this opportunity has not been utilized. The reason for this is mainly that the hunters' interest organizations have great political power. From being a necessity to provide food, hunting has become a callous hobby or cultural psychopathy. This is in contrast to the fact that only a small minority of the population hunts.

The author Stig Nordskilde is a Danish lawyer who has argued for maintaining ecosystems with great biodiversity and against hunters who destroy food networks by killing carnivores and herbivores. He has studied mammalian behaviour in particular, and photographed these in the northern hemisphere, including in Alaska, the Yukon, Greenland, Svalbard, and Scandinavia.
