A leopard war is about to break out. In this 40,000-hectare enclave plagued by climate change, resources are becoming increasingly scarce for wildlife.

Will the mother leopard be able to protect her offspring from the many dangers? Can the cubs master the art of survival? A gripping animal tale that follows the destiny of a family of felines for 3 years, in the wilds of Botswana.

These killers are feared by all the local wildlife.  But for the past few years, this region has been hit by drought, and a dam being constructed upstream has dried up the river’s flow. Whereas prey was once abundant, it has now fled the area, and the lionesses are struggling for survival. They resort to attacking the giraffes for food

The Alps – wild mountains, extreme lives, but also a magical world. This majestic mountain range connects eight countries and reaches heights of up to 4,000 metres above sea level. At a length of 1,200 kilometres, the Alps form both a connecting bridge between western and eastern Europe and a high barrier between southern and central Europe. The mountains act as a mighty water reservoir and continental watershed, feeding innumerable rivers that flow into three different oceans.  Their highest peak, Mont Blanc, is surrounded by long, soaring mountains with ice-covered slopes. These great summits are just one reason the so-called “Roof of Europe” continues to fascinate – across the continent and around the world. The incredible diversity of landscapes, flora and fauna makes the Alps a unique natural treasure at the heart of Europe.
