1 00:00:37,038 --> 00:00:41,959 Asia - the largest of all the Earth's continents. 2 00:00:45,254 --> 00:00:50,676 It stretches from the equator to beyond the Arctic Circle. 3 00:00:53,137 --> 00:00:56,807 This is a continent of extremes. 4 00:01:01,395 --> 00:01:07,401 Here, temperatures can drop to below minus 60 degrees Celsius. 5 00:01:09,528 --> 00:01:12,782 On land, survival is almost impossible. 6 00:01:15,534 --> 00:01:18,329 But for a few weeks in summer, 7 00:01:18,454 --> 00:01:22,875 the ice melts and the coast is transformed. 8 00:01:33,678 --> 00:01:37,515 This is one of the biggest gatherings of mammals 9 00:01:37,640 --> 00:01:41,143 to be found anywhere on Earth. 10 00:02:34,989 --> 00:02:37,700 These are Pacific walrus. 11 00:02:38,993 --> 00:02:42,663 For most of the year they feed out in the Arctic Ocean, 12 00:02:42,788 --> 00:02:45,374 emerging to rest on the sea ice. 13 00:02:47,668 --> 00:02:51,464 But now climate change has melted the ice here, 14 00:02:51,589 --> 00:02:56,052 and the only place within reach of their feeding grounds where they can rest 15 00:02:56,135 --> 00:02:59,305 are a few beaches, such as this one. 16 00:03:02,224 --> 00:03:07,938 100,000 of them, almost the entire world population, are here. 17 00:03:12,985 --> 00:03:14,820 They are gigantic. 18 00:03:14,945 --> 00:03:18,574 A male can weigh over a tonne... 19 00:03:22,578 --> 00:03:25,790 ...and many die in the scrum. 20 00:03:37,301 --> 00:03:42,348 On a beach, 250 miles to the west, there's a further danger. 21 00:03:47,770 --> 00:03:49,146 Polar bears. 22 00:03:56,070 --> 00:04:02,118 They, too, have been forced to spend more time ashore by the dwindling ice. 23 00:04:11,419 --> 00:04:15,256 And now they're very hungry. 24 00:04:37,778 --> 00:04:44,452 But adult walrus are tough, well armed and agile in water, 25 00:04:44,577 --> 00:04:47,830 and could fatally injure the bear. 26 00:04:50,749 --> 00:04:51,959 He's failed. 27 00:05:01,427 --> 00:05:05,306 The narrow beaches here are backed by cliffs... 28 00:05:08,309 --> 00:05:13,355 ...and some walrus scramble up them, escaping the crowd. 29 00:05:37,630 --> 00:05:43,219 At the top, they are 80 metres above the beach... 30 00:05:46,180 --> 00:05:50,643 ...but this is not a place where a walrus should be. 31 00:05:53,771 --> 00:05:57,107 Nor are they the only ones to have found it. 32 00:06:00,194 --> 00:06:02,404 The bears have got up here too. 33 00:06:18,879 --> 00:06:22,758 The walrus's instinct is to find safety in the water. 34 00:06:28,514 --> 00:06:30,599 They can still smell the sea. 35 00:06:37,982 --> 00:06:39,567 And they can hear it. 36 00:06:49,159 --> 00:06:53,914 Just the polar bear's presence is enough to spook the walrus. 37 00:07:09,888 --> 00:07:14,393 Many walrus that climb the cliffs never make it back to the ocean. 38 00:07:17,896 --> 00:07:20,399 Even once the polar bears have moved on, 39 00:07:20,524 --> 00:07:26,238 the walrus need to return to the sea, and some take the nearest way to do so. 40 00:07:42,421 --> 00:07:44,465 As one crashes on the rocks, 41 00:07:44,590 --> 00:07:49,094 those on the beach stampede and more lives are lost. 42 00:08:26,423 --> 00:08:31,095 In the course of just a few days, over 200 walrus die. 43 00:08:50,364 --> 00:08:53,617 Now the polar bears can feed on the carcasses. 44 00:09:06,130 --> 00:09:09,341 These events only occur once every few years, 45 00:09:09,466 --> 00:09:14,012 but as the world warms and the ice retreats still further, 46 00:09:14,138 --> 00:09:16,390 they may become more frequent. 47 00:09:20,978 --> 00:09:24,773 Inland, the ground is gripped by winter 48 00:09:24,898 --> 00:09:27,359 for six months of the year. 49 00:09:30,154 --> 00:09:36,034 Two million square miles of northern Russia are locked beneath the ice. 50 00:09:39,246 --> 00:09:43,751 But even so, some creatures have managed to make their homes here. 51 00:09:46,462 --> 00:09:50,299 They leave evidence of their presence in the snow. 52 00:09:53,135 --> 00:09:57,306 These tracks all lead in one direction. 53 00:10:30,172 --> 00:10:35,511 Kamchatka has the highest density of active volcanoes on the planet. 54 00:10:37,221 --> 00:10:42,017 Temperatures underground reach 250 degrees Celsius... 55 00:10:43,227 --> 00:10:47,481 ...pushing up cauldrons of boiling mud and clouds of steam... 56 00:10:50,067 --> 00:10:51,568 ...but in spite of the dangers, 57 00:10:51,693 --> 00:10:56,323 some creatures travel long distances to visit the area. 58 00:11:08,210 --> 00:11:10,379 A Kamchatka brown bear. 59 00:11:12,422 --> 00:11:16,301 He spent the long winter sleeping in a den below ground 60 00:11:16,426 --> 00:11:19,346 and now he is extremely hungry. 61 00:11:24,643 --> 00:11:29,940 But finding food means getting dangerously close to the scalding fountains. 62 00:11:39,241 --> 00:11:41,869 This is the only place for many miles around 63 00:11:41,994 --> 00:11:47,040 where a bear can reach grass that is snow free, thanks to the hot earth. 64 00:11:59,469 --> 00:12:04,224 Putting a foot wrong here could lead to real trouble, 65 00:12:04,349 --> 00:12:06,476 and bodies have been found of bears 66 00:12:06,602 --> 00:12:11,106 that stumbled into the pools and were scalded to death. 67 00:12:17,529 --> 00:12:19,948 And this bear is not alone. 68 00:12:30,000 --> 00:12:33,545 Brown bears, by and large, are solitary creatures 69 00:12:33,670 --> 00:12:36,089 and this is one of the few times of the year 70 00:12:36,214 --> 00:12:38,759 when they tolerate the presence of others. 71 00:12:44,973 --> 00:12:49,770 And now they are so well fed and relaxed that they even have time to play. 72 00:13:11,458 --> 00:13:18,215 This volcanic spot has become a warm oasis in Asia's frigid north. 73 00:13:35,315 --> 00:13:40,445 Away from Arctic Russia, Asia has the hottest deserts, 74 00:13:40,570 --> 00:13:45,534 highest mountains and tallest jungles on our planet. 75 00:13:47,744 --> 00:13:50,998 This is a continent of incredible variety... 76 00:13:55,127 --> 00:13:57,129 ...but it was not always so. 77 00:13:59,006 --> 00:14:01,967 Some 89 million years ago, 78 00:14:02,092 --> 00:14:08,557 India was an island lying away to the south, but it drifted northwards, 79 00:14:08,682 --> 00:14:12,310 pushing up the sediments between it and mainland Asia. 80 00:14:16,273 --> 00:14:18,442 Over millions of years, 81 00:14:18,567 --> 00:14:24,740 the sediments lying between crumpled up and rose to form the Himalayas. 82 00:14:39,087 --> 00:14:44,634 Now these are the tallest mountains on the planet. 83 00:14:46,428 --> 00:14:49,973 They stand over five miles high. 84 00:14:53,852 --> 00:14:59,858 India is still moving northwards, and these mountains are still rising. 85 00:15:07,866 --> 00:15:12,454 Asia's mountains stretch all the way from Afghanistan, 86 00:15:12,579 --> 00:15:17,042 across northern India, to here in central China. 87 00:15:20,629 --> 00:15:26,968 These are the mountains of Shennongjia, among China's highest. 88 00:15:42,859 --> 00:15:48,490 The forests here were, until comparatively recently, the least known in the world. 89 00:15:51,493 --> 00:15:57,165 Few outsiders had any idea of what animals might be living in them. 90 00:16:15,642 --> 00:16:20,939 There were stories of human-like monsters - yetis, abominable snowmen - 91 00:16:21,064 --> 00:16:24,192 who left strange footprints in the snow... 92 00:16:28,155 --> 00:16:30,031 ...but little else. 93 00:16:32,742 --> 00:16:38,790 And indeed there are monkeys living in these snowy forests, 94 00:16:38,915 --> 00:16:40,750 and they're very strange. 95 00:16:45,630 --> 00:16:49,551 Meet the blue-faced, golden-coated, 96 00:16:49,676 --> 00:16:53,221 snub-nosed snow monkey. 97 00:17:01,104 --> 00:17:04,191 They are among the heftiest of monkeys. 98 00:17:10,405 --> 00:17:14,034 Big animals keep warm more easily than small ones, 99 00:17:14,159 --> 00:17:19,289 and they survive in colder conditions than any other monkey on Earth. 100 00:17:23,627 --> 00:17:26,129 They all have snub noses. 101 00:17:26,254 --> 00:17:31,134 Perhaps prominent ones would only too easily get frostbitten. 102 00:17:34,721 --> 00:17:39,976 The whole group huddles together at the slightest opportunity to keep warm... 103 00:17:45,857 --> 00:17:47,525 ...and who wouldn't? 104 00:18:06,044 --> 00:18:11,758 Even adults, if they get separated from the group, can freeze to death. 105 00:18:25,981 --> 00:18:32,362 Now, in the depths of winter, food is desperately hard to find. 106 00:18:38,368 --> 00:18:41,705 The head of the family leads them to the edge of their territory 107 00:18:41,830 --> 00:18:44,165 in search of something to eat. 108 00:18:46,209 --> 00:18:50,171 The only food here is wretchedly unnourishing - 109 00:18:50,297 --> 00:18:55,635 bark, moss and lichen. 110 00:18:57,178 --> 00:19:01,266 There's hardly enough to sustain one monkey, let alone a family. 111 00:19:05,353 --> 00:19:07,272 But they share it peaceably. 112 00:19:15,322 --> 00:19:18,616 Survival depends on the group keeping together. 113 00:19:24,497 --> 00:19:28,084 In these mountains, any food is precious. 114 00:19:32,630 --> 00:19:34,758 A rival group. 115 00:19:43,475 --> 00:19:46,644 They, too, are searching for food. 116 00:19:57,155 --> 00:19:59,491 The two males go head to head. 117 00:20:43,618 --> 00:20:46,538 And now the females join the fray. 118 00:21:01,845 --> 00:21:04,639 Outnumbered, the intruders retreat. 119 00:21:09,686 --> 00:21:12,188 Their leader is the last to go. 120 00:21:23,992 --> 00:21:27,495 The fight was over the smallest of meals, 121 00:21:27,620 --> 00:21:33,209 but it was ferocious nonetheless, and the family is now scattered... 122 00:21:34,752 --> 00:21:36,963 ...but they must stay together. 123 00:21:38,339 --> 00:21:41,301 The youngest are already badly chilled. 124 00:21:48,141 --> 00:21:52,604 She can see her father, but has she the strength to reach him? 125 00:22:30,808 --> 00:22:33,645 Back to safety and warmth. 126 00:22:44,572 --> 00:22:47,992 The huddle is the only source of warmth 127 00:22:48,117 --> 00:22:51,538 in these bleak, frozen forests. 128 00:23:14,185 --> 00:23:20,942 To the west of the Himalayas, in Iran, lie some of the hottest deserts on Earth. 129 00:23:26,030 --> 00:23:28,741 This is the Lut Desert... 130 00:23:30,451 --> 00:23:34,706 ...and here temperatures can reach 70 degrees Celsius. 131 00:23:50,972 --> 00:23:56,269 The blisteringly hot rocks and baking sands of Iran's deserts 132 00:23:56,394 --> 00:23:59,105 may appear totally lifeless... 133 00:24:03,109 --> 00:24:08,156 ...but a few trees manage to grow in the shade of the canyon walls... 134 00:24:11,451 --> 00:24:15,288 ...and here at least migrating birds passing through 135 00:24:15,413 --> 00:24:17,790 can stop for a little rest. 136 00:24:22,629 --> 00:24:24,922 A flycatcher. 137 00:24:26,257 --> 00:24:29,886 With luck, there might be a meal of some kind here. 138 00:24:35,642 --> 00:24:39,145 There are spiders in the crevices. 139 00:24:39,270 --> 00:24:41,898 Not much, but worth having. 140 00:24:47,862 --> 00:24:50,156 And there's something moving up there. 141 00:25:34,867 --> 00:25:37,203 The bird was mistaken. 142 00:25:37,328 --> 00:25:40,456 It was a viper with a lethal bite. 143 00:25:53,720 --> 00:25:56,889 This species has only recently been discovered 144 00:25:57,014 --> 00:26:01,519 and, so far, it has been found nowhere else but here. 145 00:26:04,439 --> 00:26:06,524 Its camouflage is so effective 146 00:26:06,649 --> 00:26:10,528 that it's almost impossible to see it on these rocks. 147 00:26:14,949 --> 00:26:21,372 And on its tail, moveable scales have been modified to look like a spider's legs... 148 00:26:24,917 --> 00:26:26,878 ...and its tip like an abdomen. 149 00:26:41,476 --> 00:26:47,482 Migrating birds only appear in this barren desert during a few weeks of the year. 150 00:26:50,902 --> 00:26:55,281 This is the snake's only chance to eat for months. 151 00:27:08,294 --> 00:27:09,796 A shrike. 152 00:27:10,838 --> 00:27:15,134 It has flown here from Africa and hasn't fed for days. 153 00:28:10,773 --> 00:28:12,984 Better luck next time. 154 00:28:22,326 --> 00:28:27,707 Conditions are almost as harsh on the dry plains of northern India. 155 00:28:35,923 --> 00:28:40,219 A male Sarada lizard does his best to get himself noticed. 156 00:28:41,804 --> 00:28:43,639 It's breeding time. 157 00:28:55,192 --> 00:28:58,779 The wide open spaces are a good place to be seen. 158 00:29:11,083 --> 00:29:13,711 He's only 7cm tall, 159 00:29:13,836 --> 00:29:18,424 but a rock will help to make him conspicuous. 160 00:29:38,986 --> 00:29:42,281 And he's already been noticed by one female. 161 00:29:46,869 --> 00:29:49,455 It's time for him to show off. 162 00:29:57,672 --> 00:30:03,803 The more healthy and virile he is, the brighter his colours are. 163 00:30:10,643 --> 00:30:15,147 And females like bright, flashy colours. 164 00:30:21,070 --> 00:30:26,450 But he, it seems, is not as conspicuous as he might be. 165 00:30:31,080 --> 00:30:32,957 In the neighbouring territory, 166 00:30:33,082 --> 00:30:37,503 there's another male who's found an even bigger rock. 167 00:30:46,721 --> 00:30:51,017 So the newcomer is not making quite such a good impression. 168 00:30:52,643 --> 00:30:57,523 The one on the big rock is attracting all the females. 169 00:31:16,876 --> 00:31:21,964 The newcomer will need a higher platform if he's to be seen by a female, 170 00:31:22,089 --> 00:31:24,592 and he'd better do something about it. 171 00:31:26,093 --> 00:31:28,387 He only lives for a year. 172 00:31:33,642 --> 00:31:35,728 This is his one chance. 173 00:31:40,357 --> 00:31:44,195 He will have to fight, if necessary. 174 00:32:05,299 --> 00:32:07,593 H is rival isn't backing down. 175 00:32:26,737 --> 00:32:29,782 Sarada males can fight to the death. 176 00:33:34,263 --> 00:33:35,973 The newcomer has won. 177 00:33:45,399 --> 00:33:51,113 Now he can claim the high platform and the best territory... 178 00:33:53,240 --> 00:33:56,827 ...and the females will choose him for a partner, 179 00:33:56,952 --> 00:34:00,581 as long as he can fight off the other claimants. 180 00:34:16,847 --> 00:34:20,142 As the Himalayas rose over millions of years, 181 00:34:20,267 --> 00:34:23,646 they eventually formed a gigantic barrier 182 00:34:23,771 --> 00:34:28,859 that prevented rain clouds from the south travelling farther north... 183 00:34:31,403 --> 00:34:36,450 ...and a completely new weather system developed in Southern Asia. 184 00:34:52,591 --> 00:34:54,051 The monsoon. 185 00:35:04,895 --> 00:35:09,149 These drenching annual rains transformed Southern Asia. 186 00:35:11,527 --> 00:35:13,153 Dense rainforests formed, 187 00:35:13,279 --> 00:35:19,576 in which plants and animals of all kinds were able to proliferate and evolve. 188 00:35:26,625 --> 00:35:31,547 Some of the tallest jungles grow in Indonesia, 189 00:35:31,672 --> 00:35:35,884 the home of the largest of all tree-living animals of any kind... 190 00:35:39,221 --> 00:35:41,056 ...the orang-utan. 191 00:35:46,395 --> 00:35:50,274 There is a multitude of things to eat here, 192 00:35:50,399 --> 00:35:53,569 but you have to know where to find them. 193 00:35:58,949 --> 00:36:03,704 Young orangs stay with their mother for years, learning how to do that. 194 00:36:03,829 --> 00:36:07,624 This youngster has only just started. 195 00:36:22,514 --> 00:36:27,061 Termites - an important source of protein. 196 00:36:43,410 --> 00:36:47,122 But perhaps they are an acquired taste. 197 00:37:03,347 --> 00:37:07,643 He's off to search for something he might prefer. 198 00:37:22,074 --> 00:37:24,284 It's hard to know where to look... 199 00:37:38,549 --> 00:37:41,844 ...or where it's safe to clamber. 200 00:37:53,605 --> 00:37:58,318 Different levels in the forest contain different foods, 201 00:37:58,444 --> 00:38:03,991 and some of the most delicious are in the very highest parts of the canopy, 202 00:38:04,116 --> 00:38:06,869 50 metres above the ground. 203 00:38:19,047 --> 00:38:23,218 He's a couple of years old and he's already getting adventurous. 204 00:38:25,345 --> 00:38:29,057 H is mother could climb right to the top in ten minutes or so 205 00:38:29,183 --> 00:38:34,271 if she wanted to, but she lingers, to keep an eye on him. 206 00:38:38,525 --> 00:38:42,779 A fall from this height could be fatal. 207 00:38:54,958 --> 00:38:57,878 Where the gaps between the branches are too wide for him, 208 00:38:58,003 --> 00:39:01,924 his mother lets him use her body as a bridge. 209 00:39:18,774 --> 00:39:21,818 Only ten metres to go before the top. 210 00:39:31,370 --> 00:39:34,706 But it's hard going for small hands. 211 00:39:46,718 --> 00:39:49,054 He's had enough. 212 00:39:58,897 --> 00:40:01,608 Time for a rest... 213 00:40:03,193 --> 00:40:04,695 ...with mother. 214 00:40:14,621 --> 00:40:18,417 And this is his reward... 215 00:40:18,542 --> 00:40:22,045 ...ripe mangos, sweet and juicy. 216 00:40:28,719 --> 00:40:31,722 There's so much he must learn. 217 00:40:39,271 --> 00:40:43,233 He will depend entirely on his mother until he's seven. 218 00:40:44,901 --> 00:40:49,698 It's the longest of all childhoods except ours. 219 00:40:57,998 --> 00:40:59,958 In these dense forests, 220 00:41:00,083 --> 00:41:04,504 it's not easy for animals to see one another at any distance, 221 00:41:04,630 --> 00:41:08,300 but songs carry well through the jungle. 222 00:41:13,263 --> 00:41:15,432 This is the characteristic sound 223 00:41:15,557 --> 00:41:20,228 that echoes through the Sumatran forest at every dawn. 224 00:41:28,362 --> 00:41:30,405 But what can this be? 225 00:41:33,825 --> 00:41:37,454 Of all the sounds in the Indonesian forests, 226 00:41:37,579 --> 00:41:41,500 this is one of the strangest to our ears. 227 00:41:42,959 --> 00:41:46,838 It can be heard nowhere else on Earth. 228 00:42:04,731 --> 00:42:06,608 And this is the singer. 229 00:42:09,444 --> 00:42:12,781 A Sumatran rhinoceros. 230 00:42:16,785 --> 00:42:22,874 She's tiny, only a fifth of the size of her more familiar African relatives. 231 00:42:25,168 --> 00:42:28,463 Her head could rest comfortably on your knee. 232 00:42:34,594 --> 00:42:37,848 She is the gardener of this Eden. 233 00:42:41,351 --> 00:42:46,189 She doesn't just live in it - she helps to create and sustain it. 234 00:42:49,443 --> 00:42:53,572 She eats fruits and then sheds the seeds in her droppings 235 00:42:53,697 --> 00:42:57,534 and so spreads the foods she prefers through the forest. 236 00:43:03,915 --> 00:43:10,130 In this dense tangle, she uses sound to locate a possible mate. 237 00:43:18,597 --> 00:43:21,975 But her calls are unanswered. 238 00:43:23,393 --> 00:43:26,313 She is living behind a fence... 239 00:43:29,983 --> 00:43:32,277 ...for her own protection. 240 00:43:38,700 --> 00:43:45,207 In the past, Sumatran rhinos were widespread throughout Southern Asia. 241 00:43:49,044 --> 00:43:52,339 Today, there are fewer than 70. 242 00:44:06,061 --> 00:44:10,732 It may well be that as she approaches the end of her natural life, 243 00:44:10,857 --> 00:44:15,695 she will have become one of the last of her species... 244 00:44:29,209 --> 00:44:31,461 ...because, in the last 40 years, 245 00:44:31,586 --> 00:44:36,675 one-third of the forests of Southeast Asia has been destroyed 246 00:44:36,800 --> 00:44:41,596 in order to sell timber and food products around the world. 247 00:44:46,977 --> 00:44:52,732 The forests of Borneo and Sumatra, home to the orang-utan, rhinos 248 00:44:52,858 --> 00:44:58,822 and thousands of other species that have evolved here over millions of years... 249 00:44:58,947 --> 00:45:05,537 ...are now in real danger of being lost for ever. 250 00:45:16,840 --> 00:45:21,094 It seems that the animals whose home this once was 251 00:45:21,219 --> 00:45:25,807 are worth less to us than the land they lived on. 252 00:45:29,102 --> 00:45:33,815 Viewed from space, the scale of destruction is only too obvious. 253 00:45:33,940 --> 00:45:38,945 Asia has undergone a faster change in the last 100 years 254 00:45:39,070 --> 00:45:42,741 than at any other time in its history. 255 00:45:45,535 --> 00:45:50,040 Its forests are being annihilated, its cities are expanding, 256 00:45:50,165 --> 00:45:54,044 and as the human population approaches 4.6 billion, 257 00:45:54,169 --> 00:45:58,173 the largest of all continents is no longer able, it seems, 258 00:45:58,298 --> 00:46:01,676 to allow space for its wildlife. 259 00:46:14,940 --> 00:46:19,778 The oceans around Southern Asia are also feeling this pressure. 260 00:46:26,534 --> 00:46:30,914 These seas feed billions of people around the world. 261 00:46:35,460 --> 00:46:40,715 For many fishermen here, their catch is their only source of livelihood. 262 00:46:46,972 --> 00:46:52,268 And there is one fish here that they prize above all others. 263 00:47:02,612 --> 00:47:04,739 The whale shark. 264 00:47:10,412 --> 00:47:15,875 It swims slowly, gently harvesting the plankton. 265 00:47:17,961 --> 00:47:20,547 It's almost 20 metres long - 266 00:47:20,672 --> 00:47:22,799 the largest fish in the world. 267 00:47:29,597 --> 00:47:32,350 They are also under threat. 268 00:47:34,728 --> 00:47:36,771 Like many shark species in Asia, 269 00:47:36,896 --> 00:47:41,901 populations have declined by more than half in recent years. 270 00:47:58,501 --> 00:48:01,504 They are an easy and valuable catch. 271 00:48:08,595 --> 00:48:14,225 But here, there is a respect for the seas and their inhabitants. 272 00:48:17,312 --> 00:48:23,735 Whale shark hunting has now been banned across Indonesia's waters. 273 00:48:26,529 --> 00:48:31,451 This whale shark plays a different part in the lives of these fishermen. 274 00:48:36,164 --> 00:48:42,837 They feed him, and the relationship seems to bring joy to both parties, 275 00:48:42,962 --> 00:48:49,094 and with this new protection has come something truly remarkable. 276 00:49:02,440 --> 00:49:08,113 Whale sharks from far away are seeking out these fishermen, 277 00:49:08,238 --> 00:49:14,744 and in these safe waters, there is a chance for their numbers to increase. 278 00:49:18,706 --> 00:49:24,921 And maybe one day other shark species will be protected too. 279 00:49:32,262 --> 00:49:38,309 The people here have made a simple but extraordinary choice - 280 00:49:38,434 --> 00:49:44,983 fishing in a way that is sustainable for themselves and the animals. 281 00:49:50,405 --> 00:49:55,201 Caring for wildlife is surely our shared responsibility. 282 00:49:58,746 --> 00:50:04,961 Across this vast continent and across the world, it is decisions like these 283 00:50:05,086 --> 00:50:10,341 that are key to protecting the planet's most precious diversity. 284 00:50:17,807 --> 00:50:22,812 Next time... a land of the unexpected. 285 00:50:31,779 --> 00:50:35,533 The richest and most diverse continent on Earth... 286 00:50:39,412 --> 00:50:41,122 ...South America.
