The animal filmmaker Andreas Kieling uses several examples from different regions on earth to focus on the influences of humans on wild animals. In Yellowstone national park, he investigates how resettled wolves change nature and fauna. What does the settling of Indian parakeets mean for the local bird life in some German regions? In Asia, Kieling concerns himself with koalas, whose food source is becoming increasingly nutrient-poor. And how can one avoid conflicts between bears and local farmers in Slovenia?
