The last of a natural history of Britain and Ireland, presented by Julian Pettifer New Landscapes
Much of our wildlife has found refuge in our 20th-century landscapes. The new wetlands of gravel pits and reservoirs shelter great crested grebes and cormorants, and sand martins excavate homes in working quarries. On the man-made cliffs of industry ravens and mistle thrushes nest, while the cooled slag of a steel works becomes carpeted by vivid flowers teeming with insect life. Even motorway verges have become havens for wildlife. These unofficial nature reserves supplement those that preserve more ancient, fragile landscapes.

from Larne
Roger Royle takes the shortest sea journey (just 80 minutes) between Britain and Ireland and arrives in the busy ferry port of Larne. 'Gateway to Ulster' and 'Gateway to the Glens', Lame caters for the industrialist and welcomes the tourist. Its people still embrace an age-old faith, as Roger discovers on board Hammy Robinson 's small ferry boat. The wiry boatman respects the mighty power of the sea, but 'St Patrick blessed the ferry that nobody would ever drown on it; and nobody has'. Rejoice, the Lord is King (Darwall's 148th); To the name of our salvation (Grafton): How great thou art!; Dear Lord and Father of mankind

The investigation takes them to a seaside hotel where some rather unusual people are staying...
