Part one of two. The comedian travels along one of the world's most contentious borders, visiting places in America and Mexico to find out what life is like on both sides. Sue starts her journey at the western end of the border in the Mexican city of Tijuana, where she helps Honduran volunteers building a hostel for fellow refugees fleeing violence in their country

Part two of two. Sue visits the city of Juarez, which adjoins El Paso on the other side of the border, the two effectively forming a single large city spreading across two nations. A 57-mile section of border wall runs through the two cities, but does not stop thousands of people coming and going across every day. Sue confronts her fear of horses to try out a Mexican form of dressage and meets a woman living in the US who has been separated from her husband, who is not legally allowed to enter the US

Originally broadcast live from the Arctic, this series follows the struggles of polar bears living on this frozen tundra and highlights the impact that environmental changes are having on the bears and the changing world around them. Simon Reeve, Kate Humble and Gordon Buchanan examine the effects of climate change and the struggles these bears now face as the sea ice continues to melt at an alarming rate

From Tewkesbury in Gloucestershire, Michael Portillo heads to the castle of Eastnor at the foot of the Malvern Hills. He also visits Coleford in the Forest of Dean, Slimbridge in Gloucestershire, and Bristol Temple Meads. From there he heads to Filton to investigate the centre of Britain's post-war aviation industry

Wildlife that live thousands of kilometres from land, featuring footage of baby turtles using debris as life rafts and whales sharks embarking on lengthy voyages across the Pacific to the point where it is safest to give birth. Special pressure-proof cameras are used to film sperm whales hunting for squid a kilometre beneath the surface and the impact of plastic pollution on the oceans is revealed

Footage of wildlife inhabiting underwater kelp forests, including thousands of giant cuttlefish spawning along a restricted area of rocky reef off the south coast of Australia. Males outnumber females 11 to one, which leads to fierce competition. Larger males use brute force to drive off competition, while their smaller rivals use deception by mimicking the appearance of females. The programme also features tiger sharks hunting for green turtles in fields of seagrass and spider crabs trying to avoid predators while they shed their shells

Footage of animals that live on the coast, including sea lions working in packs to hunt tuna in the shallows and moray eels that venture out of the water to seek out food on dry rocks. Puffins must brave predators to bring a mouthful of food back to their young and king penguins go without food for a month while they moult. Plus, footage of the bizarre Leaping Blenny, a fish that hates the water

The series concludes with a look at the ways human activity can impact on aquatic wildlife, including albatrosses unwittingly feeding their offspring plastic, mother dolphins with contaminated milk, and communications between animals being disrupted by noise. However, there are signs of hope, including the thriving Norwegian Spring-Spawning Herring, previously on the brink of extinction, and efforts to save endangered species like the whale shark and to preserve the eggs of giant leatherback turtles

The naturalist joins a team of scientists examining the 200 million-year-old fossilised remains of an ichthyosaur, a vast sea creature which was discovered on Dorset's Jurassic Coast. As the skeleton is reassembled, advanced imaging technology and computer animation is used to create a simulation of the sea creature as it would have appeared when it was still alive - the most detailed reconstruction of its kind ever attempted. Meanwhile, forensic investigators painstakingly examine the bones to solve the mystery of how the ichthyosaur died
