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?

Am Madadh-Allaidh

For 12,000 years wolves roamed Scotland. However, over three centuries ago, we exterminated them. This film reveals the rise and fall of the Scottish wolf and explores the question of whether they should be re-introduced. Wolves arrived as the last ice age ended, following the herds of deer and reindeer that crossed a now-lost land bridge from Europe. For thousands of years, wolves and humans shared the landscape as apex predators, with the wolf entering human art, myth and belief. However, farming put wolves and humans on a collision course, and, after centuries of persecution, wolves became extinct in Scotland. Since then, deer numbers have exploded, and many of Scotland’s woodlands have been stripped bare. Some argue for the wolf’s return. Could we, and should we, hear the howl of the wolf once more in the Highlands?
