1 00:00:14,500 --> 00:00:18,620 Search and rescue teams are crossing Iceland's central plateau. 2 00:00:21,260 --> 00:00:25,580 A few kilometres below them, a huge reservoir of molten magma 3 00:00:25,580 --> 00:00:28,380 shakes the ground as it makes its way to the surface. 4 00:00:32,260 --> 00:00:35,180 The question is not IF an eruption will take place, 5 00:00:35,180 --> 00:00:37,580 but when...and where. 6 00:00:41,180 --> 00:00:45,460 Icelanders have turned their unstable, cold, rugged island 7 00:00:45,460 --> 00:00:48,700 into one of the most modern and culturally-rich nations on earth. 8 00:00:50,420 --> 00:00:53,180 But they still keep one foot in the wild 9 00:00:53,180 --> 00:00:56,620 and a very careful eye on the beast stirring beneath them. 10 00:00:59,540 --> 00:01:02,340 Over what turns out to be an explosive year, 11 00:01:02,340 --> 00:01:04,780 and through the eyes of wild foxes... 12 00:01:06,980 --> 00:01:08,380 ..an eider duck farmer... 13 00:01:11,140 --> 00:01:12,820 ..and Viking horsemen, 14 00:01:12,820 --> 00:01:15,300 we'll see why everything on Iceland 15 00:01:15,300 --> 00:01:18,940 remains uniquely connected to the land underfoot. 16 00:01:33,100 --> 00:01:36,220 Under the eerie glow of the Northern Lights, 17 00:01:36,220 --> 00:01:38,900 Iceland is in the iron grip of winter. 18 00:01:47,020 --> 00:01:49,460 Lying close to the Arctic Circle, 19 00:01:49,460 --> 00:01:52,260 with just a few hours of light a day, 20 00:01:52,260 --> 00:01:54,420 it has endured months below zero. 21 00:02:11,380 --> 00:02:15,780 At this time of year, it's hard to imagine Iceland's fiery origins, 22 00:02:15,780 --> 00:02:18,780 but the island emerged as molten lava 23 00:02:18,780 --> 00:02:20,860 from deep beneath the Atlantic Ocean. 24 00:02:22,580 --> 00:02:25,060 It's one of the planet's newest pieces of land. 25 00:02:29,340 --> 00:02:32,460 Everywhere are reminders of how little time it's had 26 00:02:32,460 --> 00:02:34,940 to shed its raw, rocky character, 27 00:02:34,940 --> 00:02:38,820 and how closely it's connected to the very centre of the earth. 28 00:02:48,180 --> 00:02:52,300 Iceland is so new and so isolated in the North Atlantic 29 00:02:52,300 --> 00:02:54,660 that, until relatively recently, 30 00:02:54,660 --> 00:02:57,700 there were no land mammals here at all. 31 00:03:11,100 --> 00:03:12,940 But during the last Ice Age, 32 00:03:12,940 --> 00:03:17,140 when it was connected to Greenland by ice bridges and ice floes, 33 00:03:17,140 --> 00:03:20,020 a very tenacious predator turned up. 34 00:03:26,660 --> 00:03:28,540 The Arctic fox. 35 00:03:31,820 --> 00:03:33,860 Iceland's first land mammal, 36 00:03:33,860 --> 00:03:37,380 in its many colour variations, was here to stay. 37 00:03:43,580 --> 00:03:47,460 But how it survived on Iceland without any of its regular prey, 38 00:03:47,460 --> 00:03:52,340 like lemmings, has long fascinated scientist Ester Unnsteinsdottir. 39 00:03:54,420 --> 00:03:58,020 'This is an Arctic species, it's adapted to the Arctic winter, 40 00:03:58,020 --> 00:04:00,860 'which is really cold. 41 00:04:00,860 --> 00:04:03,900 'And you can see it on the thick fur, 42 00:04:03,900 --> 00:04:07,540 'it's the thickest fur in the universe, so very well insulating.' 43 00:04:08,980 --> 00:04:11,020 It's actually better than a polar bear's 44 00:04:11,020 --> 00:04:12,380 against the biting cold. 45 00:04:19,140 --> 00:04:21,940 Enduring extreme weather is one thing - 46 00:04:21,940 --> 00:04:25,220 its biggest challenge on Iceland is finding food. 47 00:04:27,020 --> 00:04:28,580 They need to eat. 48 00:04:28,580 --> 00:04:31,940 And if they don't have enough food in the wintertime, 49 00:04:31,940 --> 00:04:37,020 especially before breeding, they don't manage to breed properly. 50 00:04:39,460 --> 00:04:41,460 There is a remarkable lifeline. 51 00:04:43,100 --> 00:04:46,100 An arm of the Gulf Stream helps to keep much of Iceland's 52 00:04:46,100 --> 00:04:49,020 long, rocky coastline ice-free. 53 00:04:49,020 --> 00:04:52,060 So even in winter, foxes can scavenge 54 00:04:52,060 --> 00:04:56,020 the washed-up remains of fish, seabirds and sea mammals. 55 00:05:11,260 --> 00:05:16,420 Only the toughest foxes hold on to a slice of good shoreline territory 56 00:05:16,420 --> 00:05:18,620 and get the chance to breed. 57 00:05:20,660 --> 00:05:22,540 But first, they have to find a mate. 58 00:05:37,980 --> 00:05:41,580 A dark male appears to have won over a brown female. 59 00:05:42,940 --> 00:05:45,740 A white male is desperate to mate with her, too. 60 00:05:51,780 --> 00:05:53,980 And succeeds in grabbing her attention. 61 00:05:58,580 --> 00:06:02,140 For a while, he seems to have outfoxed his rival. 62 00:06:11,500 --> 00:06:13,260 But it doesn't end well for him. 63 00:06:15,340 --> 00:06:17,700 The white male will have to try elsewhere. 64 00:06:21,420 --> 00:06:25,180 Hopefully, this brown female, with the victor in tow, 65 00:06:25,180 --> 00:06:27,700 has the strength she'll need to have a family. 66 00:06:33,580 --> 00:06:38,100 For the weak or the inexperienced, winter is a punishing time. 67 00:06:39,500 --> 00:06:41,940 Less than half of all foxes survive. 68 00:06:54,140 --> 00:06:57,180 Sea mammals have an easier ride. 69 00:06:57,180 --> 00:06:58,860 The ice-free waters offer 70 00:06:58,860 --> 00:07:01,380 some of the best fishing in the North Atlantic... 71 00:07:03,060 --> 00:07:07,340 ..attracting not just seals, but whales and dolphins. 72 00:07:09,580 --> 00:07:13,420 The fertile seas were a good reason for humans to settle here, too. 73 00:07:17,300 --> 00:07:21,740 The first Vikings colonised Iceland just over a thousand years ago. 74 00:07:23,500 --> 00:07:26,820 Down the generations, through fishing and farming, 75 00:07:26,820 --> 00:07:28,660 they have carved out a unique way 76 00:07:28,660 --> 00:07:30,940 of dealing with the many limits to life. 77 00:07:33,140 --> 00:07:37,420 Most of Iceland's people, just over 300,000 of them, 78 00:07:37,420 --> 00:07:40,060 are descended from the original settlers. 79 00:07:40,060 --> 00:07:43,860 And many still work the land in tried and tested ways. 80 00:07:46,300 --> 00:07:48,740 Even their livestock traces back to the animals 81 00:07:48,740 --> 00:07:50,380 the Vikings brought with them. 82 00:07:57,300 --> 00:08:01,700 Purest and most admired is the Icelandic horse. 83 00:08:03,900 --> 00:08:06,940 It's smaller and much hardier than most other breeds. 84 00:08:08,260 --> 00:08:11,900 Owners give them a little help towards winter's end, 85 00:08:11,900 --> 00:08:15,020 but mostly, they tough out the cruellest of weather. 86 00:08:17,220 --> 00:08:21,260 The best way to raise livestock here is to keep the animals semi-wild. 87 00:08:22,860 --> 00:08:25,540 It gives them the character and spirit to survive 88 00:08:25,540 --> 00:08:27,780 in this austere volcanic landscape. 89 00:08:36,900 --> 00:08:39,180 But with little prime grazing land, 90 00:08:39,180 --> 00:08:42,140 Icelanders could never rely on their livestock alone. 91 00:08:46,260 --> 00:08:50,900 Long ago, the arrival of squadrons of swans, ducks and geese 92 00:08:50,900 --> 00:08:53,740 would have offered relief from dwindling winter rations. 93 00:08:58,340 --> 00:09:00,820 One species offered much more than a meal. 94 00:09:04,140 --> 00:09:07,980 Eider ducks are among the millions of birds that are drawn to Iceland 95 00:09:07,980 --> 00:09:10,020 from all around the North Atlantic. 96 00:09:14,940 --> 00:09:19,740 These days, Thor Bjornsson makes an unusual living from them. 97 00:09:19,740 --> 00:09:23,620 But he can't start work until the eiders have finished pairing up 98 00:09:23,620 --> 00:09:25,140 and have come ashore. 99 00:09:38,580 --> 00:09:42,340 He, and the birds, are waiting for spring. 100 00:09:52,740 --> 00:09:56,500 Exposed all winter to brutal Atlantic storms, 101 00:09:56,500 --> 00:10:00,140 Iceland has been blanketed by huge volumes of snow. 102 00:10:10,820 --> 00:10:14,420 When that melts, it fills thousands of streams and rivers. 103 00:10:18,420 --> 00:10:20,300 And cascades over some of Europe's 104 00:10:20,300 --> 00:10:22,820 largest and most powerful waterfalls. 105 00:10:49,540 --> 00:10:51,820 Iceland is so new and remote 106 00:10:51,820 --> 00:10:55,180 that relatively few species have made it here. 107 00:11:00,900 --> 00:11:03,740 Its hardy pioneers are always under pressure. 108 00:11:05,540 --> 00:11:10,140 Even now, it's a race to make the most of longer, warmer days ahead. 109 00:11:16,540 --> 00:11:18,420 After a winter of famine, 110 00:11:18,420 --> 00:11:22,860 male ptarmigan are hungry to reach the buds, packed with proteins, 111 00:11:22,860 --> 00:11:25,700 which are swelling at the top of willows and birches. 112 00:11:30,700 --> 00:11:32,820 It's a precarious high-wire act 113 00:11:32,820 --> 00:11:36,380 for a bird that spends the majority of its time on the ground. 114 00:11:45,020 --> 00:11:47,860 Down on the coast, Thor is impatient 115 00:11:47,860 --> 00:11:50,220 for the eiders to get on with mating. 116 00:11:58,820 --> 00:12:01,660 Millions of other migrating and resident birds 117 00:12:01,660 --> 00:12:04,860 are already nursing eggs, set to take advantage 118 00:12:04,860 --> 00:12:08,180 of what will be a very short, but bountiful summer. 119 00:12:14,100 --> 00:12:15,860 BIRDSONG 120 00:12:22,140 --> 00:12:27,260 Eventually, the eiders return to the western islands of Breidafjordur, 121 00:12:27,260 --> 00:12:28,900 finding the same nest scrapes 122 00:12:28,900 --> 00:12:32,420 that their mothers and grandmothers used before them. 123 00:12:37,020 --> 00:12:40,060 The mother duck cradles her eggs in a pillow of down 124 00:12:40,060 --> 00:12:42,900 collected from her own breast feathers. 125 00:12:45,580 --> 00:12:47,740 There is no other duck down like it. 126 00:12:51,460 --> 00:12:54,500 It's this down that Thor wants to harvest, 127 00:12:54,500 --> 00:12:57,340 but he'll need his extended family to help gather it. 128 00:13:01,900 --> 00:13:06,060 Thor's farm consists of nearly 300 small islands. 129 00:13:06,060 --> 00:13:09,580 And they'll have to deal with over 3,000 wild eider ducks. 130 00:13:14,540 --> 00:13:16,820 It's going to be a busy few weeks. 131 00:13:22,700 --> 00:13:25,100 Spring has finally reached Hornstrandir, 132 00:13:25,100 --> 00:13:29,420 the craggy, lonely, north-western corner of Iceland. 133 00:13:37,540 --> 00:13:41,020 After a severe winter, this female fox 134 00:13:41,020 --> 00:13:43,940 is hanging around one of only two den sites. 135 00:13:46,340 --> 00:13:50,940 The lack of food over the past few months will have taken its toll, 136 00:13:50,940 --> 00:13:53,180 but now she has to step up a gear. 137 00:13:54,820 --> 00:13:57,660 She's looking after not just herself... 138 00:14:08,020 --> 00:14:10,860 ..but six newborn cubs. 139 00:14:16,140 --> 00:14:17,980 Her work is cut out. 140 00:14:17,980 --> 00:14:20,820 She's a mum with a sky-high milk bill. 141 00:14:20,820 --> 00:14:23,460 Just to keep up production, she's going to have to spend 142 00:14:23,460 --> 00:14:25,900 the next weeks hunting fulltime. 143 00:14:42,180 --> 00:14:45,220 Arctic foxes are feisty opportunists. 144 00:14:47,220 --> 00:14:50,500 They may be small, but when livestock arrived on Iceland, 145 00:14:50,500 --> 00:14:54,340 they soon worked out how to kill animals much larger than themselves. 146 00:14:56,580 --> 00:15:00,020 In response, the early settlers began hunting foxes 147 00:15:00,020 --> 00:15:02,060 to keep their numbers under control. 148 00:15:04,060 --> 00:15:07,100 Today, foxes still take livestock 149 00:15:07,100 --> 00:15:11,300 and the hunting quotas enshrined in law in the 13th century 150 00:15:11,300 --> 00:15:13,020 are still in force. 151 00:15:16,500 --> 00:15:19,060 On Iceland's marginal land, 152 00:15:19,060 --> 00:15:23,780 the challenges facing both fox and farmer cannot be underestimated. 153 00:15:25,220 --> 00:15:27,860 Making a living out here is tough. 154 00:15:30,900 --> 00:15:34,860 For farmers like Halldor, horses are their pride and joy. 155 00:15:39,220 --> 00:15:42,140 These days, Halldor and his son-in-law, Snorri, 156 00:15:42,140 --> 00:15:44,100 mostly breed them for riding. 157 00:15:50,980 --> 00:15:53,420 Horses are still better than 4x4s 158 00:15:53,420 --> 00:15:56,820 on Iceland's rough tracks and mountain passes. 159 00:15:56,820 --> 00:15:59,100 Just as sturdy and dependable 160 00:15:59,100 --> 00:16:01,980 as when they were the backbone of Icelandic communities. 161 00:16:06,260 --> 00:16:09,860 HE SPEAKS OWN LANGUAGE: 162 00:16:52,060 --> 00:16:55,540 The finest horses became highly-regarded status symbols. 163 00:17:15,900 --> 00:17:18,980 SNORRI IN ENGLISH: You had a lot of respect if you had the best horse. 164 00:17:18,980 --> 00:17:20,980 Even if you were a poor farmer, 165 00:17:20,980 --> 00:17:23,740 if you had the best horse, you had respect. 166 00:17:23,740 --> 00:17:27,300 HALLDOR SPEAKS OWN LANGUAGE 167 00:17:27,300 --> 00:17:30,940 SNORRI TRANSLATING: "Really important for the young guys to have a nice horse 168 00:17:30,940 --> 00:17:32,980 "when they were looking for girls. 169 00:17:32,980 --> 00:17:36,180 "When you came with good clothes, on a nice horse, 170 00:17:36,180 --> 00:17:37,820 "you had a good chance." 171 00:17:47,620 --> 00:17:51,460 Every spring, Halldor checks on his pregnant mares. 172 00:17:51,460 --> 00:17:54,900 He hopes his favourite stallion will be the father. 173 00:17:56,060 --> 00:17:59,980 The very best foals will be much admired at the end-of-year round-up, 174 00:17:59,980 --> 00:18:02,820 but Halldor has no control over their arrival. 175 00:18:04,420 --> 00:18:06,900 They give birth to their foals in secret. 176 00:18:06,900 --> 00:18:09,140 Often after dark, and without help. 177 00:18:14,660 --> 00:18:18,180 Halldor has to trust that his mares are robust enough to cope. 178 00:18:32,780 --> 00:18:37,260 Over 3,000 eider ducks are now settled on eggs on Thor's islands. 179 00:18:45,580 --> 00:18:48,980 He and his family carefully comb each rocky outcrop, 180 00:18:48,980 --> 00:18:50,540 looking for nests. 181 00:18:53,300 --> 00:18:55,860 Thor's unusual livelihood allows him 182 00:18:55,860 --> 00:18:58,820 to spend time in the wildest parts of Iceland, 183 00:18:58,820 --> 00:19:01,700 among the nature he loves so much. 184 00:19:01,700 --> 00:19:04,340 'I started about 1970. 185 00:19:05,660 --> 00:19:08,460 'And I was 14 years old then. 186 00:19:08,460 --> 00:19:13,500 'I found it very, very nice to be with the birds, like this. 187 00:19:13,500 --> 00:19:17,180 'Collecting down and all the wildlife around it.' 188 00:19:18,900 --> 00:19:22,900 Thor carefully sets the eggs aside, removes the down, 189 00:19:22,900 --> 00:19:26,300 and will re-cushion the eggs in soft, warm hay. 190 00:19:28,580 --> 00:19:33,180 The female ducks can then return to their duties with no harm done. 191 00:19:33,180 --> 00:19:37,900 His yield is limited by the number of birds that return each year. 192 00:19:41,460 --> 00:19:44,020 Some years are better than others and... 193 00:19:45,660 --> 00:19:49,180 ..we get up to 55 kilos of eiderdown. 194 00:19:51,100 --> 00:19:57,540 Normally, it's about 65 nests in one kilo of down. 195 00:19:59,020 --> 00:20:02,300 Eiders have proved tricky to domesticate. 196 00:20:02,300 --> 00:20:05,420 Their down can only be farmed from wild birds. 197 00:20:05,420 --> 00:20:08,500 To increase overall numbers, 198 00:20:08,500 --> 00:20:11,020 Thor collects and rears a few offspring 199 00:20:11,020 --> 00:20:13,340 that may not otherwise survive. 200 00:20:13,340 --> 00:20:18,900 'A lot of young ones, eider ducklings, die in many ways. 201 00:20:18,900 --> 00:20:23,780 'Bad, er...weather, wet and windy. 202 00:20:23,780 --> 00:20:25,940 'They cannot get enough food. 203 00:20:25,940 --> 00:20:28,660 'So normally, they maybe raise up one duckling, 204 00:20:28,660 --> 00:20:30,900 'two ducklings, something like that. 205 00:20:30,900 --> 00:20:32,940 'We take one or two eggs from the nest, 206 00:20:32,940 --> 00:20:35,780 'depends how many eggs are in the nest. 207 00:20:35,780 --> 00:20:40,060 'When we started here, it was about something between 500 or 600 eiders 208 00:20:40,060 --> 00:20:43,420 'nesting in the homeland area, but now it's more than 1,000, 209 00:20:43,420 --> 00:20:45,300 'so they come back.' 210 00:20:48,140 --> 00:20:51,220 While his eggs are incubating, Thor gets down to business. 211 00:20:54,900 --> 00:20:59,340 Nearly three quarters of all eider duck down comes from Iceland, 212 00:20:59,340 --> 00:21:01,220 and it's all gathered by hand. 213 00:21:02,780 --> 00:21:06,340 Thor's family painstakingly pick the down clean 214 00:21:06,340 --> 00:21:08,860 before it's bagged up for sale. 215 00:21:08,860 --> 00:21:13,660 Most becomes a cosy filling for high-end duvets, quilts and jackets. 216 00:21:13,660 --> 00:21:15,700 THEY SPEAK OWN LANGUAGE 217 00:21:19,060 --> 00:21:23,700 Its secret may lie in the way the fibres flex and lock together, 218 00:21:23,700 --> 00:21:26,380 creating thousands of minuscule air pockets. 219 00:21:27,740 --> 00:21:29,820 It's such effective insulation 220 00:21:29,820 --> 00:21:32,700 that it's been used to keep astronauts warm in space. 221 00:21:36,300 --> 00:21:39,380 This is duck down that's flown to the moon and back. 222 00:21:41,780 --> 00:21:43,460 CHIRPING 223 00:21:46,500 --> 00:21:51,780 After a few days under a heat lamp, Thor's ducklings begin to hatch. 224 00:21:51,780 --> 00:21:53,380 They grow quickly. 225 00:21:53,380 --> 00:21:57,660 In the wild, eider ducklings can fledge after just a month. 226 00:21:57,660 --> 00:21:59,260 CHIRPING 227 00:22:03,420 --> 00:22:04,740 But under Thor's wing, 228 00:22:04,740 --> 00:22:08,380 they stand a much better chance of making it to adulthood. 229 00:22:08,380 --> 00:22:10,540 CHEEPING 230 00:22:24,140 --> 00:22:26,460 For these first days, at least, 231 00:22:26,460 --> 00:22:29,660 they only have eyes for their new duck dad. 232 00:22:33,380 --> 00:22:35,620 They won't follow him around long-term, 233 00:22:35,620 --> 00:22:38,260 but Thor will have to spend the rest of the summer 234 00:22:38,260 --> 00:22:40,500 as a stay-at-home father, 235 00:22:40,500 --> 00:22:43,940 teaching them skills they'll need to become wild birds. 236 00:22:48,740 --> 00:22:51,660 The longest days of the year are approaching, 237 00:22:51,660 --> 00:22:54,900 when the sun barely dips below the horizon. 238 00:22:54,900 --> 00:22:56,540 The fullness of summer 239 00:22:56,540 --> 00:22:59,820 is only really felt around the island's edges. 240 00:23:06,100 --> 00:23:10,260 Hardly anything lives on the vast, ash-covered central plateau. 241 00:23:13,220 --> 00:23:16,900 Its many volcanoes erupt too frequently and violently 242 00:23:16,900 --> 00:23:19,100 to give life much chance. 243 00:23:21,940 --> 00:23:25,620 It's like a sleeping giant that everyone's turned their back on, 244 00:23:25,620 --> 00:23:28,220 but dares not forget is there. 245 00:23:41,180 --> 00:23:43,380 Watching over the fox family, 246 00:23:43,380 --> 00:23:47,340 Ester is spending more and more time on the Hornstrandir peninsula. 247 00:23:51,300 --> 00:23:53,020 The cubs have been weaned, 248 00:23:53,020 --> 00:23:56,460 but Mum's workload just gets bigger by the day. 249 00:23:59,940 --> 00:24:02,020 Sibling rivalry can be lethal. 250 00:24:04,460 --> 00:24:08,060 It's thought that each fight reinforces their rank in the family. 251 00:24:10,060 --> 00:24:13,340 Dogged determination decides who gets most food 252 00:24:13,340 --> 00:24:16,180 and who, ultimately, survives. 253 00:24:37,540 --> 00:24:40,380 This mum seems to be made of particularly stern stuff 254 00:24:40,380 --> 00:24:43,540 and is providing for all six of the cubs. 255 00:24:54,380 --> 00:24:57,620 She's raising her family close to one of the most prolific 256 00:24:57,620 --> 00:25:00,020 seabird colonies in Iceland. 257 00:25:02,140 --> 00:25:05,100 There's lots of tempting food on offer. 258 00:25:05,100 --> 00:25:08,540 The problem is that it's perched on sheer walls of rock. 259 00:25:27,860 --> 00:25:32,140 If ever there was a high-stakes game, this mother is playing it. 260 00:25:43,100 --> 00:25:46,980 One false step and she will plunge hundreds of metres 261 00:25:46,980 --> 00:25:49,020 onto the rocks below. 262 00:25:49,020 --> 00:25:51,460 Her cubs will effectively die with her. 263 00:25:52,860 --> 00:25:55,660 SQUAWKING 264 00:26:18,660 --> 00:26:20,060 She's found a kittiwake. 265 00:26:23,340 --> 00:26:24,940 But with a growing family, 266 00:26:24,940 --> 00:26:28,020 she will have to risk her life over and over again. 267 00:26:30,260 --> 00:26:33,300 Today, she has the cliffs to herself, 268 00:26:33,300 --> 00:26:37,380 but until the 1950s, foxes were in direct competition 269 00:26:37,380 --> 00:26:41,180 with the people who eked out a living on this far-flung peninsula. 270 00:26:42,940 --> 00:26:48,340 'It was very harsh, even for humans, you know. It was really tough. 271 00:26:48,340 --> 00:26:52,980 'Bad winters and, er...not easy to survive. 272 00:26:52,980 --> 00:26:56,260 'So, both for humans and foxes. 273 00:26:56,260 --> 00:26:59,540 'And they were probably using the same resources, 274 00:26:59,540 --> 00:27:01,500 'both space and food, 275 00:27:01,500 --> 00:27:03,740 'so they were feeding on birds and eggs. 276 00:27:03,740 --> 00:27:05,780 'And that's what people were also feeding on.' 277 00:27:08,220 --> 00:27:10,060 On the remote island of Grimsey, 278 00:27:10,060 --> 00:27:13,500 they still gather eggs from the massive summer colonies. 279 00:27:17,140 --> 00:27:21,460 Its long coastline and towering cliffs of resistant volcanic rock 280 00:27:21,460 --> 00:27:25,180 provide ledge space for thousands of kittiwakes and guillemots. 281 00:27:27,940 --> 00:27:30,580 And burrows above for puffins. 282 00:27:30,580 --> 00:27:32,580 BIRDSONG 283 00:27:41,220 --> 00:27:45,100 Across Iceland, there is still the taste for seabird eggs. 284 00:27:45,100 --> 00:27:47,500 A traditional and free-range alternative 285 00:27:47,500 --> 00:27:49,820 to battery-farmed chicken eggs. 286 00:27:51,620 --> 00:27:54,580 These days, the kit may be relatively modern, 287 00:27:54,580 --> 00:27:57,820 but it still requires an old-fashioned head for heights. 288 00:28:11,740 --> 00:28:14,260 Timing is crucial. 289 00:28:14,260 --> 00:28:16,780 Eggs are scooped up right after laying. 290 00:28:16,780 --> 00:28:19,460 The theory being that as soon as the birds realise 291 00:28:19,460 --> 00:28:21,460 their egg has gone, they'll re-lay. 292 00:28:23,180 --> 00:28:26,060 The collectors simply delay the hatch by a few days. 293 00:28:54,620 --> 00:28:57,340 The length of cliff which each collector sweeps 294 00:28:57,340 --> 00:28:59,100 is strictly controlled. 295 00:29:04,620 --> 00:29:07,700 Today, these eggs are sold through supermarkets, 296 00:29:07,700 --> 00:29:10,420 or traded for autumn berries from the mainland. 297 00:29:29,820 --> 00:29:33,860 For many, foraging remains a part of everyday life, 298 00:29:33,860 --> 00:29:36,900 tapping into the rich natural resources around them. 299 00:29:45,860 --> 00:29:49,700 The most remarkable resource of all is the heat beneath their feet. 300 00:29:55,220 --> 00:29:58,860 The island lies over the edge of two continental plates 301 00:29:58,860 --> 00:30:01,300 that are pulling away from each other. 302 00:30:01,300 --> 00:30:04,260 Iceland is being stretched apart in the middle. 303 00:30:06,780 --> 00:30:09,620 It's the easiest place for boiling molten rock 304 00:30:09,620 --> 00:30:11,260 to rise towards the surface. 305 00:30:14,180 --> 00:30:17,020 This readily heats groundwater, 306 00:30:17,020 --> 00:30:19,140 which, day to day, can be rather useful. 307 00:30:20,420 --> 00:30:24,100 Long ago, Icelanders discovered how it could slow-cook 308 00:30:24,100 --> 00:30:27,260 one of their most celebrated foods, lava bread. 309 00:30:30,780 --> 00:30:34,780 Every household has its own secret recipe for roobrau, 310 00:30:34,780 --> 00:30:37,660 but each loaf will be baked in much the same way. 311 00:30:41,780 --> 00:30:45,860 Once the dough is bucketed up, it will be placed in a hot spring - 312 00:30:45,860 --> 00:30:48,300 nearly every rural community has one - 313 00:30:48,300 --> 00:30:51,460 and then left for 24 hours. 314 00:31:03,660 --> 00:31:06,500 The immense geothermal power on offer 315 00:31:06,500 --> 00:31:09,100 has transformed the lives of all Icelanders. 316 00:31:10,780 --> 00:31:13,060 They live just south of the Arctic Circle. 317 00:31:13,060 --> 00:31:15,740 Yet, modern, ground-heated greenhouses 318 00:31:15,740 --> 00:31:18,340 allow them to ripen vegetables and fruits 319 00:31:18,340 --> 00:31:21,100 that wouldn't otherwise stand a chance of growing here. 320 00:31:28,220 --> 00:31:30,500 They've created a sustainable bubble 321 00:31:30,500 --> 00:31:32,820 in which plants and their pollinators 322 00:31:32,820 --> 00:31:36,020 defy the limits of growing on raw, northern rock. 323 00:31:40,820 --> 00:31:44,580 But along with their daily bread, Icelanders are fed updates 324 00:31:44,580 --> 00:31:47,540 on the many earthquakes that occur on the island. 325 00:31:47,540 --> 00:31:50,460 It's as routine as the weather forecast. 326 00:31:50,460 --> 00:31:53,340 And this year, it seems, more important than ever. 327 00:31:56,780 --> 00:32:00,340 In late May, a swarm of 200 earthquakes 328 00:32:00,340 --> 00:32:04,180 register under the Bardarbunga volcano in central Iceland. 329 00:32:06,020 --> 00:32:09,860 It lies under Europe's largest glacier, Vatnajokull. 330 00:32:09,860 --> 00:32:13,380 And eruptions in the past have caused catastrophic floods. 331 00:32:19,420 --> 00:32:24,060 There's no evidence as yet that magma is on its way to the surface, 332 00:32:24,060 --> 00:32:26,540 but pilots overflying the area 333 00:32:26,540 --> 00:32:30,300 are asked to keep an eye on any changes to the ground below them. 334 00:32:37,060 --> 00:32:39,340 On this extraordinary island, 335 00:32:39,340 --> 00:32:41,540 ordinary life simply goes on. 336 00:32:44,460 --> 00:32:47,020 There have been over a dozen eruptions 337 00:32:47,020 --> 00:32:48,980 in Halldor's lifetime alone. 338 00:32:48,980 --> 00:32:51,780 Right now, he has more immediate concerns. 339 00:32:58,820 --> 00:33:01,180 One of his mares has just given birth. 340 00:33:03,500 --> 00:33:06,980 Like many creatures that evolved on open grassland, 341 00:33:06,980 --> 00:33:10,700 the foal's instinct is to get on its feet as quickly as possible. 342 00:33:39,220 --> 00:33:40,700 It seems healthy. 343 00:33:55,860 --> 00:33:58,340 The new foals will stay close to their mothers 344 00:33:58,340 --> 00:33:59,980 for most of their first year. 345 00:34:04,020 --> 00:34:07,500 But it may be the last Halldor sees of them for a long while. 346 00:34:12,660 --> 00:34:17,460 Soon, all his horses will move up the valley and into the mountains. 347 00:34:17,460 --> 00:34:20,260 It will give these lower pastures a break. 348 00:34:22,860 --> 00:34:26,180 But the move is also important to encourage the foals to run free. 349 00:34:27,780 --> 00:34:30,180 If they're to survive their first winter, 350 00:34:30,180 --> 00:34:32,020 they need to become resilient. 351 00:34:39,540 --> 00:34:41,780 Horses from all the farms around here 352 00:34:41,780 --> 00:34:44,860 are allowed to return to their roots. 353 00:34:44,860 --> 00:34:48,460 Just like the ancestral wild horse of the Eurasian Steppes, 354 00:34:48,460 --> 00:34:50,540 they'll roam in large herds 355 00:34:50,540 --> 00:34:52,740 and won't see their owners 356 00:34:52,740 --> 00:34:54,620 for many months. 357 00:34:54,620 --> 00:34:58,260 You want to keep this wildness a little bit in the horses. 358 00:34:58,260 --> 00:35:00,740 And this is the best place to do that. 359 00:35:00,740 --> 00:35:05,780 And it's also really important that young horses go there, foals, 360 00:35:05,780 --> 00:35:08,460 to learn this as quickly as possible. 361 00:35:08,460 --> 00:35:13,620 This strengthens their mind a lot to do this. 362 00:35:13,620 --> 00:35:17,500 Because you never know in Iceland, if... Just... 363 00:35:17,500 --> 00:35:20,180 If it gets lost on the mountains, 364 00:35:20,180 --> 00:35:23,460 they know how to help themselves. 365 00:35:23,460 --> 00:35:28,740 I think also for the growing of the horses and the young horses, 366 00:35:28,740 --> 00:35:33,620 it's, like, it grows much better and stronger on the mountains. 367 00:35:36,420 --> 00:35:38,900 The Skagafjordur region prides itself 368 00:35:38,900 --> 00:35:41,700 on producing the very best Icelandic horses. 369 00:35:44,860 --> 00:35:47,140 Strict rules control the breed. 370 00:35:49,340 --> 00:35:52,700 A horse sold abroad is never allowed to return, 371 00:35:52,700 --> 00:35:56,500 having lost the magic mix of wildness and trainability. 372 00:35:58,980 --> 00:36:01,820 This is the trait Halldor's foals must develop 373 00:36:01,820 --> 00:36:04,900 if they are to do him proud at the end-of-year round-up. 374 00:36:20,580 --> 00:36:23,380 The short summer is pressing on. 375 00:36:23,380 --> 00:36:27,420 Wild eider ducks are already leading their young broods out on the water. 376 00:36:36,660 --> 00:36:38,540 The eider is a diving duck 377 00:36:38,540 --> 00:36:41,660 that spends the whole winter living at sea. 378 00:36:41,660 --> 00:36:43,900 It's vital they become powerful swimmers. 379 00:36:49,620 --> 00:36:51,700 Thor's ducklings, too, 380 00:36:51,700 --> 00:36:54,660 must begin learning how to face the trials ahead. 381 00:36:59,900 --> 00:37:02,580 Younger members of the family lead the way. 382 00:37:06,340 --> 00:37:10,300 They get very quickly very big and strong. 383 00:37:10,300 --> 00:37:14,780 And we bring them to the sea every day, or sometimes twice a day, 384 00:37:14,780 --> 00:37:17,340 to feed in the sea and swim a little bit. 385 00:37:20,620 --> 00:37:23,820 Here, they'll build up their muscles and sharpen their instincts. 386 00:37:25,180 --> 00:37:27,180 They're still vulnerable to the cold 387 00:37:27,180 --> 00:37:29,500 and to ravenous black-backed gulls, 388 00:37:29,500 --> 00:37:32,620 so the children must guide and protect them. 389 00:37:35,500 --> 00:37:38,140 First days, we have to look very well after them 390 00:37:38,140 --> 00:37:40,900 because they want to go away. 391 00:37:40,900 --> 00:37:44,660 So we try to gather them and so they don't swim away. 392 00:37:46,820 --> 00:37:49,260 This wilful streak is good. 393 00:37:49,260 --> 00:37:51,220 It means they haven't been tamed. 394 00:38:07,420 --> 00:38:10,660 All in all, it's a fun way for the kids to connect with nature. 395 00:38:21,020 --> 00:38:22,980 And the smallest member of the family 396 00:38:22,980 --> 00:38:25,140 gets to talk down to someone else. 397 00:38:48,460 --> 00:38:50,260 It's home-time. 398 00:38:50,260 --> 00:38:55,460 The ducklings are gently herded and counted back in. 399 00:38:55,460 --> 00:38:57,820 Where they'll fluff themselves back up 400 00:38:57,820 --> 00:39:00,420 in readiness for the next stage of their training. 401 00:39:07,740 --> 00:39:09,540 For now, it's job done. 402 00:39:14,420 --> 00:39:16,580 BIRDSONG 403 00:39:16,580 --> 00:39:20,820 In Hornstrandir, the Atlantic Ocean is slowly gnawing 404 00:39:20,820 --> 00:39:24,540 at what remains of a very ancient and immense lava flow. 405 00:39:29,060 --> 00:39:33,220 On its unforgiving edge, the mother fox has defied the odds. 406 00:39:41,940 --> 00:39:45,220 All six of her cubs are still alive. 407 00:39:45,220 --> 00:39:47,980 Although life is a challenge, they currently stand 408 00:39:47,980 --> 00:39:50,940 a better chance in Iceland than elsewhere in the Arctic. 409 00:39:54,500 --> 00:39:59,660 'There's very few Arctic foxes left in Scandinavia. 410 00:39:59,660 --> 00:40:03,620 'And they have been endangered for many, many years. 411 00:40:03,620 --> 00:40:09,100 'But they're facing troubles that we are not facing here in Iceland.' 412 00:40:09,100 --> 00:40:13,220 Ester believes the big problem for Arctic foxes in Scandinavia 413 00:40:13,220 --> 00:40:16,860 is the northward march of the red fox, due to climate change. 414 00:40:18,180 --> 00:40:21,020 As it moves into Arctic fox territory, 415 00:40:21,020 --> 00:40:23,660 the red fox takes over their den sites, 416 00:40:23,660 --> 00:40:27,220 competes for food and even kills adults and young. 417 00:40:31,980 --> 00:40:36,300 The Arctic foxes on Iceland remain out of reach. 418 00:40:36,300 --> 00:40:38,900 The island is an important stronghold for them. 419 00:40:41,740 --> 00:40:43,500 Mum's job is nearly done. 420 00:40:45,340 --> 00:40:48,060 In the next few weeks, the cubs will leave home. 421 00:40:56,180 --> 00:40:58,460 Hunger may force them into taking livestock, 422 00:40:58,460 --> 00:41:00,260 where they risk being shot. 423 00:41:12,820 --> 00:41:15,700 The odds are that not all of these cubs will survive 424 00:41:15,700 --> 00:41:18,540 the coming winter, or go on to breed. 425 00:41:20,420 --> 00:41:23,580 But the Arctic fox has an almost heroic ability 426 00:41:23,580 --> 00:41:26,180 to turn hardship into opportunity. 427 00:41:29,700 --> 00:41:32,700 This mum's given them the best possible start in life. 428 00:41:50,500 --> 00:41:53,260 This far north, the limits to life 429 00:41:53,260 --> 00:41:56,220 for animals and humans, are very stark. 430 00:41:57,540 --> 00:42:00,700 So Icelanders have never been shy of taking from nature. 431 00:42:03,060 --> 00:42:07,180 Traditionally, they've harvested everything from seabirds to whales, 432 00:42:07,180 --> 00:42:11,060 fish to seals, some of which they still take today. 433 00:42:15,220 --> 00:42:17,860 But it's clear that if you live on an island, 434 00:42:17,860 --> 00:42:20,100 especially one so remote and northerly, 435 00:42:20,100 --> 00:42:22,540 you cannot take more than you need. 436 00:42:28,300 --> 00:42:30,540 Ever since the Vikings first landed, 437 00:42:30,540 --> 00:42:32,940 fishing the rich offshore waters 438 00:42:32,940 --> 00:42:35,300 have been fundamental to the country's economy. 439 00:42:36,980 --> 00:42:39,660 In the 1970s, Iceland even used gunboats 440 00:42:39,660 --> 00:42:43,140 to defend a 200-mile fishing limit around their coast. 441 00:42:47,220 --> 00:42:49,140 Today, with careful management, 442 00:42:49,140 --> 00:42:52,700 their fisheries are some of the most sustainable in the world. 443 00:43:01,220 --> 00:43:04,340 Their long-term thinking has helped other countries, too. 444 00:43:07,820 --> 00:43:11,060 Icelandic rivers are important spawning grounds 445 00:43:11,060 --> 00:43:12,900 for the Atlantic salmon. 446 00:43:16,940 --> 00:43:20,380 But in the 1980s, salmon started to decline, 447 00:43:20,380 --> 00:43:22,020 due mainly to overfishing 448 00:43:22,020 --> 00:43:24,580 by commercial operations on the high seas. 449 00:43:29,780 --> 00:43:32,820 By raising funds to buy out the netting operations, 450 00:43:32,820 --> 00:43:35,220 effectively paying them not to fish, 451 00:43:35,220 --> 00:43:38,380 millions of salmon were given a chance 452 00:43:38,380 --> 00:43:41,500 to return to rivers, from Norway to North America. 453 00:43:45,980 --> 00:43:48,460 The problem is far from over. 454 00:43:48,460 --> 00:43:51,540 Striking a balance between harvesting and protecting 455 00:43:51,540 --> 00:43:53,500 is an ongoing effort, 456 00:43:53,500 --> 00:43:56,540 but Icelanders manage it in their own unique way. 457 00:43:58,180 --> 00:44:00,380 It's a country where hunting and gathering 458 00:44:00,380 --> 00:44:03,180 sit side by side with modern life. 459 00:44:10,180 --> 00:44:13,620 A nation with a dynamic economy, built around Reykjavik, 460 00:44:13,620 --> 00:44:16,460 the most northerly capital city in the world. 461 00:44:18,500 --> 00:44:21,580 Cheap, clean, renewable power warms homes, 462 00:44:21,580 --> 00:44:24,780 keeps the lights on and provides mains' hot water. 463 00:44:26,420 --> 00:44:29,100 Even city pavements have underfloor heating. 464 00:44:31,500 --> 00:44:34,540 Reykjavik's Opera House celebrates music and drama 465 00:44:34,540 --> 00:44:37,500 inspired by the original Icelandic sagas. 466 00:44:38,820 --> 00:44:42,260 But Icelanders are necessarily rooted in reality. 467 00:44:45,300 --> 00:44:48,020 They can never forget they're living over a huge 468 00:44:48,020 --> 00:44:50,980 and widening tear in the earth's crust. 469 00:44:53,140 --> 00:44:55,140 And as summer draws to a close, 470 00:44:55,140 --> 00:45:00,460 the giant reservoir of molten rock under them is beginning to stir. 471 00:45:07,460 --> 00:45:11,500 Back on the Breidafjordur islands, wild eider offspring 472 00:45:11,500 --> 00:45:14,900 are learning what to eat by watching their parents. 473 00:45:31,780 --> 00:45:35,260 It's Thor's job to introduce his ducklings to the kind of food 474 00:45:35,260 --> 00:45:37,860 that will keep them going out on the open water. 475 00:45:40,540 --> 00:45:43,780 When they grow up, they'll be diving mainly for molluscs, 476 00:45:43,780 --> 00:45:46,740 which they eat, shell and all. 477 00:45:46,740 --> 00:45:50,060 Tiny crustaceans, stirred up from the shoreline, 478 00:45:50,060 --> 00:45:51,260 are good starter foods. 479 00:45:58,700 --> 00:46:01,500 In the end, Thor, as a surrogate duck dad, 480 00:46:01,500 --> 00:46:03,900 can only give them a helping hand. 481 00:46:10,620 --> 00:46:13,340 Little by little, they spread their wings, 482 00:46:13,340 --> 00:46:15,900 foraging a little further from home, 483 00:46:15,900 --> 00:46:18,300 becoming a little wilder every day. 484 00:46:21,340 --> 00:46:25,220 But they swim then between here, close to the island 485 00:46:25,220 --> 00:46:28,900 and go on their own trips feeding, 486 00:46:28,900 --> 00:46:31,860 but they always come home in the evening. 487 00:46:31,860 --> 00:46:35,260 So they find something in this ocean to eat, 488 00:46:35,260 --> 00:46:40,660 so it make them a good start in their new life in the world. 489 00:46:46,260 --> 00:46:48,580 Eventually, Thor leaves them on their own. 490 00:46:50,740 --> 00:46:52,620 His nurturing work is done. 491 00:46:54,700 --> 00:46:56,540 Nature will take over from here. 492 00:47:00,180 --> 00:47:02,620 But Thor hopes their homing instinct 493 00:47:02,620 --> 00:47:05,020 will bring them back to his islands next year. 494 00:47:17,860 --> 00:47:20,900 In the high pastures, ripening blueberries 495 00:47:20,900 --> 00:47:23,940 and the turning leaves mark the slide to autumn. 496 00:47:29,620 --> 00:47:32,860 Even though the first snows are dusting the mountains, 497 00:47:32,860 --> 00:47:35,300 it's a time eagerly awaited by farmers 498 00:47:35,300 --> 00:47:37,580 in the northern area of Skagafjordur, 499 00:47:37,580 --> 00:47:42,180 for it also heralds the event of their social calendar, 500 00:47:42,180 --> 00:47:43,820 the annual round-up. 501 00:48:21,220 --> 00:48:24,500 The horses might die up here in winter blizzards, 502 00:48:24,500 --> 00:48:28,140 so farmers join forces to gather up the different herds 503 00:48:28,140 --> 00:48:30,420 and drive them all down the valley. 504 00:48:32,980 --> 00:48:34,420 For this year's foals, 505 00:48:34,420 --> 00:48:37,260 it's a complete surprise to be near humans again 506 00:48:37,260 --> 00:48:39,340 and it goes against the grain. 507 00:49:02,300 --> 00:49:04,380 But this independent spirit 508 00:49:04,380 --> 00:49:07,740 is exactly what Halldor and Snorri want. 509 00:49:07,740 --> 00:49:10,860 It's what the Vikings saw in the ancestors of these horses 510 00:49:10,860 --> 00:49:13,460 when they traded them from Mongolia 511 00:49:13,460 --> 00:49:16,260 and brought them to Iceland over 1,000 years ago. 512 00:49:26,820 --> 00:49:30,100 This is horse-trading nature's way. 513 00:49:45,340 --> 00:49:46,940 THEY NEIGH 514 00:49:54,220 --> 00:49:58,100 Somehow, each farmer must separate their own horses from the crowd. 515 00:50:00,140 --> 00:50:02,740 But they're judging everyone else's at the same time. 516 00:50:11,100 --> 00:50:14,740 No horse is broken in until it's at least four years old, 517 00:50:14,740 --> 00:50:17,820 so most of them have a mind of their own. 518 00:50:17,820 --> 00:50:20,060 But this is what they love about them. 519 00:50:23,380 --> 00:50:25,340 It's been the only way to raise horses 520 00:50:25,340 --> 00:50:27,100 in Iceland's harsh environment. 521 00:50:32,060 --> 00:50:36,020 Their return from the mountains, though, always brings deep relief. 522 00:51:13,380 --> 00:51:16,220 When all is done, Halldor and Snorri 523 00:51:16,220 --> 00:51:18,780 will lead the horses back to the farm, 524 00:51:18,780 --> 00:51:21,180 as generations have done before them. 525 00:52:05,660 --> 00:52:08,380 The land under their feet demands respect. 526 00:52:09,740 --> 00:52:11,740 And in this, of all years. 527 00:52:14,420 --> 00:52:16,340 High in the central plateau, 528 00:52:16,340 --> 00:52:19,100 the Bardarbunga volcano has sprung into life. 529 00:52:20,500 --> 00:52:22,940 Over a thousand earthquakes in a single day 530 00:52:22,940 --> 00:52:28,140 suggest a huge volume of molten rock trying to reach the surface. 531 00:52:28,140 --> 00:52:29,420 But where? 532 00:52:30,900 --> 00:52:32,580 Fearing massive floods 533 00:52:32,580 --> 00:52:36,100 should the eruption melt the Vatnajokull glacier, 534 00:52:36,100 --> 00:52:39,180 search and rescue teams evacuate a vast area. 535 00:52:41,820 --> 00:52:45,460 Hour by hour, scientists track the earth tremors 536 00:52:45,460 --> 00:52:47,820 that mark the movement of the magma. 537 00:52:47,820 --> 00:52:50,740 The column of hot rock is snaking northwards. 538 00:53:01,740 --> 00:53:05,020 Eventually, it breaks through a fissure in the plains, 539 00:53:05,020 --> 00:53:06,900 just beyond the edge of the glacier. 540 00:53:08,780 --> 00:53:13,340 It's big. Probably the biggest lava eruption 541 00:53:13,340 --> 00:53:17,380 that we have seen for 30 years or so, I would guess. 542 00:53:19,860 --> 00:53:22,140 As it turns out, nothing like it 543 00:53:22,140 --> 00:53:25,700 has been seen on Iceland for over 200 years. 544 00:53:37,180 --> 00:53:40,060 The fissure is about 400 metres long, 545 00:53:40,060 --> 00:53:45,140 but lava pours out at nearly 300 cubic metres a second, 546 00:53:45,140 --> 00:53:47,260 like a cut that won't stop bleeding. 547 00:53:49,900 --> 00:53:54,140 Underneath Iceland, the Eurasian plate is pulling eastwards 548 00:53:54,140 --> 00:53:58,220 and the North American plate is pulling westwards. 549 00:53:58,220 --> 00:54:01,660 Until this eruption, the island has been spreading apart 550 00:54:01,660 --> 00:54:04,100 at two centimetres a year. 551 00:54:04,100 --> 00:54:07,140 Here, it's opening up ten times faster. 552 00:54:10,780 --> 00:54:16,180 The lava is a ferocious 1,200-degrees centigrade. 553 00:54:16,180 --> 00:54:18,140 It would melt even cast iron 554 00:54:18,140 --> 00:54:21,060 and incinerate a human being in seconds. 555 00:54:23,340 --> 00:54:27,180 This is as close as we get to seeing into the centre of the earth. 556 00:54:49,860 --> 00:54:53,660 The ground shakes as the fissure splits open even further, 557 00:54:53,660 --> 00:54:57,340 creating a rift that's 1.5 kilometres long. 558 00:55:11,820 --> 00:55:14,780 Pumped by pressure that's been building for centuries, 559 00:55:14,780 --> 00:55:18,340 superheated gas and water causes tonnes of lava 560 00:55:18,340 --> 00:55:22,340 to fountain up to 100 metres into the air all along its length. 561 00:55:24,860 --> 00:55:26,980 These are the same monumental forces 562 00:55:26,980 --> 00:55:29,300 that created Iceland in the first place. 563 00:56:33,220 --> 00:56:34,820 Over the next six months, 564 00:56:34,820 --> 00:56:38,460 the lava flow covers over 85 square kilometres. 565 00:56:45,860 --> 00:56:49,660 85,000 tonnes of poisonous sulphur dioxide 566 00:56:49,660 --> 00:56:52,260 is released into the atmosphere every day. 567 00:56:58,980 --> 00:57:02,460 In 1783, an eruption on Iceland 568 00:57:02,460 --> 00:57:05,140 threw up so much ash and sulphur dioxide 569 00:57:05,140 --> 00:57:08,540 that it's thought to have caused famine on a global scale 570 00:57:08,540 --> 00:57:11,980 and the deaths of six-million people worldwide. 571 00:57:15,020 --> 00:57:18,740 Miraculously, this fissure allows the colossal pressure 572 00:57:18,740 --> 00:57:22,220 under Bardarbunga to be released slowly. 573 00:57:22,220 --> 00:57:25,500 Had it gone off just a few kilometres away, 574 00:57:25,500 --> 00:57:28,660 explosively, under the Vatnajokull glacier, 575 00:57:28,660 --> 00:57:30,460 the picture would be very different. 576 00:57:37,180 --> 00:57:41,060 It's the ultimate reminder that the lives of all Icelanders 577 00:57:41,060 --> 00:57:43,660 depend on the raw forces beneath them. 578 00:57:50,980 --> 00:57:53,300 A wild life, 579 00:57:53,300 --> 00:57:55,820 uniquely connected to nature, it may be, 580 00:57:55,820 --> 00:57:59,620 but the remarkable people and animals that live here 581 00:57:59,620 --> 00:58:02,180 have learned how to work with the land, 582 00:58:02,180 --> 00:58:03,860 rather than fight against it. 583 00:58:06,500 --> 00:58:09,180 They've taken all of Iceland's opportunities 584 00:58:09,180 --> 00:58:11,860 and challenges in their stride. 585 00:58:13,140 --> 00:58:15,180 GENTLE BARK
