Since 25 years, the Swiss bear scientist Reno Sommerhalder has been living in Canada among these huge fur-bearing animals. In 2013, he initiated a particularly ambitious project in Siberia, trying to help young bear orphans survive their first summer. However, the crux is that the young bears must not become accustomed to humans, in order not to become a “problem bear” in adult life. The biggest threat for the Siberian bears is, beside mankind, the Amur tiger. Reno has to accept that this threat is part of the natural cycle.
