The World's Biggest Cave

In 2009 a team of British cavers went on an expedition deep within the jungle of central Vietnam. To their amazement they discovered an enormous cave which they believe to be the biggest in the world. The team, the first humans ever to enter the cave, traveled 6 kilometers underground until their way was blocked by a gigantic rock face they dubbed 'The Great Wall of Vietnam'. Now they have returned, but this time with the right equipment to climb the wall and with a geologist and zoologist to discover if this is indeed the Biggest Cave in the World and what secrets lie deep within?

Pride Ruler at Risk

Only few big cats have been as intensively studied as lions. We thought we knew everything about them. Yet some parts of their lives kept hidden in the dark.

The Search for Snow

In the northern hemisphere, snow is produced by atmospheric low pressure areas that move in from the western Atlantic in the form of huge cloud masses. Snow is vital to the balance of mountain ecosystems. Many animal and plant species at high altitudes depend on it for their survival. But due to global warming, snow is falling less and less. Will there be no more snow in the future? In the Alps and eastern US the situation is clear: as temperatures rise, snow falls less and less, and snow periods tend to shorten. This threatens the mountain flora and fauna. What future do the marmots or alpine bells have without a heat-insulating layer of snow? What future do the marmots or alpine bells have without a heat-insulating layer of snow? What will happen to the conifers in North America without the annual frost protection? Research teams are looking at the implications for snow-adapted species. The documentation shows animal mountain dwellers, who hope for the long-awaited snow every winter.
