No animal in the Amazon is more feared and more respected than the 'spirit of the river' - The Anaconda

In the heart of southern France there is a fog-prone area where, according to legend, a bloodthirsty creature wreaked havoc 250 years ago. A rumor is spreading again in this legendary place, as eyewitnesses report an animal with large paws and a long tail that crosses roads in a single leap - powerful enough to tear down a horse and leave it mutilated in the pasture. Is the Beast of Gévaudan back? The animal photographer Bruno Loisel has a supposedly more rational explanation. The animal that fits the descriptions could be a cougar, but this species of big cat is only native to America. In order to learn the proper techniques for tracking down the puma, he travels to Canada, where he accompanies a team of researchers dedicated to studying the shy, almost invisible predator. Will Bruno be able to use his findings to solve the mystery of the new beast of Gévaudan?

The pack ice off the coast is melting and depriving polar bears of their habitat so that they approach human settlements in their desperation. The changes in the nature of the Arctic Circle combine with the measurements of researchers and observations of the indigenous people to form a disturbing overall picture: In the Russian Arctic, Pandora's box has been opened!
