With a population of just over 50,000 people the Faroe Islands are spending vast sums of money digging sub-sea tunnels to keep remote communities alive. Combined with a government subsidised helicopter service, it allows islands with a handful of permanent inhabitants to thrive and has helped reverse the trend for young Faroe Islanders to emigrate in search of a more modern lifestyle. Join Tim Ecott, author of The Land of Maybe: a Faroe Islands Year, as he flies over this remote North Atlantic archipelago and ventures deep beneath the ocean to investigate why big spending on infrastructure brings huge social benefits to the islands.
