Nowadays we are witnessing the most rapid rate of extinctions since the end of the dinosaur era. Fortunately, on all continents, defenders of nature have decided to act. They struggle on a daily basis for the survival of the world’s fauna. This handful of nature lovers is struggling fiercely to save them. From Africa to Europe, from Asia to Australia and throughout the Americas, we will discover the endangered world of pachyderms, predators, reptiles, and we will follow the work of their carers.
