Wildlife conservation and field biology are not for the faint of heart. Studying wild animals in their natural habitat brings with it long periods away from home, lack of comfort, and many logistical challenges. It calls for a certain kind of grit. But equally, it requires a persistent mindset to fight the cause of wildlife when conservation clashes with company’s bottom lines, political aspirations, and the wants and needs of an expanding world population. Even amongst this hardened bunch, few people would voluntarily venture into icy wastelands to study the animals existing at the edge of the world. Joel Berger is one of them and Extreme Conservation is his story, equal parts adventure narrative as it is a meditation on the value of wild nature.
