The film offers a comprehensive examination of the exploitation of animals in modern society.

NOVA: Extreme Animal Weapons From lobster claws and dog teeth to bee stings and snake fangs, every creature depends on a weapon. But some are armed to extremes that make no practical sense - whether it's bull elks with giant 40-pound antler racks or tiny rhinoceros beetles with horns bigger than their body. What explains giant tusks, horns and claws that can slow an animal down and even impair health and nutrition? Showcasing astonishing wildlife cinematography, Extreme Animal Weapons investigates the riddle of outsize weaponry and uncovers a bold new theory about what triggers an animal arms race. In creatures as varied as dung beetles and saber-toothed tigers, shrimp and elephants, the same hidden factors trigger the race and, once started, these arms races unfold in exactly the same pattern. In this enthralling special, NOVA cracks the secret biological code that underlies nature's battleground.

An astonishing journey revealing the awesome power of the natural world. Over the course of one single day, we track the sun from the highest mountains to the remotest islands to exotic jungles.

Gombessa Expedition 3 Protected by an international treaty Antarctica has been spared the effects of hunting and fishing. But signs in ice’s cyclical patterns and its biodiversity have become worrying. Connected to the planet’s global ecosystem via atmospheric circulation and ocean currents, this white haven is suffering the effects of human activities. To document and explain what is unfolding in Antarctica, photographer, diver, and marine biologist Laurent Ballesta and photographer of extreme environments Vincent Munier will be blending their artistic perspectives of a rapidly changing continent. Laurent will tackle technical and human prowess below the ice to bear witness to its remarkable underwater life. His photographs will advance knowledge on Antarctica’s unique and little-known biodiversity. On land, his eye riveted to the lens of his camera, Vincent captures snapshots of life in an Emperor Penguin colony.

The Siberian discovery of the best-preserved woolly mammoth on record has teams of experts working around the globe, and around the clock, on some of the most ambitious projects in science. In Russia, paleontologists are conducting a historic autopsy on the 40,000-year-old beast to find out how it lived, and how it died. Meanwhile labs in South Korea and at Harvard University are using the latest advances in DNA manipulation in hopes of cloning the furry giant and introducing it to the modern world.
