Asia——Seven Worlds One Planet
Let's start~
Asia, the largest of all the earth’s continents. It stretches from the equator, to beyond the Arctic Circle. This is a continent of extremes. Here temperatures can drop to below minus sixty degree Celsius. On land, survival is almost impossible. But for a few weeks in summer, the ice melts, and the coast is transformed. This is one of the biggest gatherings of mammals to be found anywhere on earth.
These are Pacific Walrus. For most of the year they feed in the Arctic Ocean emerging to rest on the sea ice. But now climate change has melted the ice here and the only place within reach of their feeding grounds where they can rest are few beaches, such as this one. A hundred thousand of them almost the entire world population are here. They are gigantic, a male can weight over tonne, and many die in the scrum. On a beach, four hundred and fifty miles to the west, there is a further danger, Polar bears. They too have been forced to spend more time ashore by the winding ice. And now, they are very hungry. But adult walrus are tough, well?armed, and agile in water, and could fatally injure the bear, who failed.
The narrow beaches here are backed by cliffs. And some walrus scramble up them escaping the crowed. At the top, they are 80 metres above the beach. But this is not the place where a walrus should be. Now are they the only ones to have found it, the bears have got up here too. The walrus’s instinct is to find safety in the water. They can still smell the sea, and they can hear it. Just the polar bear presence is enough to spool the walrus. Many walrus that climb the cliffs never make it back to the ocean. Even once the polar bears have moved on, the walrus need to return to the sea, and some take the nearest way to do so. As one crashes on the rocks, these on the beach stampede and more lives are lost. In the course of just a few days, over 200 walrus die. Now the polar bears can feed on the carcasses. These events only occur once every few years, but as the world warms, and the ice retreats still further, they may become more frequent.
Inland, the ground is gripped by winter for 6 months of the year. Five million square kilo-miles of northern Russia, are locked beneath the ice. But even so, some creatures have managed to make their homes here. They leave evidence of their presence in the snow. These tracks all lead in one direction.
Kamchatka has the highest density of active volcanoes on the planet. Temperature under the ground reach 250 degrees Celsius, pushing up cauldrons of boiling mud and clouds of steam. But in spite of dangers, some creatures travel long distances to visit the area.
A Kamchatka brown bear?spends the long winter sleeping in a den below ground and now he is extremely hungry. But finding food means getting dangerously close to the scalding foundations. This is the only place for many miles around that a bear can reach grass that is snow-free thanks to the hot earth. Putting a foot wrong here could lead to real trouble and bodies have been found of bears that stumbled into the pools that were scalded to death. And this bear is not alone. Brown bears, by and large, are solitary creature and this is?one of the few times of the year when they tolerate the presence of others. And now, they are so well-fed and relaxed and they even have time to play. This volcanic spot has become a warm oasis in Asia’s frigid north.
Away from Arctic Russia, Asia has the hottest deserts, highest mountains and tallest jungles on our planet. This is a continent of incredible variety. But it was not always so. Some 8900 years ago, India was an island, lying away to the south. But it drifted northwards, putting up the sediments between it and mainland Asia. Over millions of years, the sediments lying between crumpled up and rose to form the Himalayas. Now, these are the tallest mountains on the planet. They reach 8900 kilo-metres?high. India is still moving northwards and these mountains are still rising. Asia’s mountains stretch all the way from Afghanistan, across Northern India to here in center of China.
These are the mountains of Shennongjia among China’s highest. The forests here were, until comparatively recently, the least known in the world. Few outsiders had any idea of what animals might be living in them. There were stories of human-like monsters, yetis. Abominable Snowmen who left strange footprints in the snow, but little else.
And indeed there are monkeys living in these snowy forests. And they are strange. Meet the blue-faced, golden-coated, snub-nosed, snow monkey. They are among the heftiest of moneys. Big animals keep warm more easily than small ones, and they survive in colder conditions than any other monkeys on earth. They all have snub-noses, perhaps prominent ones would only too easily get frostbitten. The whole group huddles together and slightest opportunity to keep warm. And who wouldn’t. Even adults, if they get separated from the group can freeze to death. Now, in the depth of winter, food is desperately hard to find. The head of the family leads them to the edge of their territory in search of something to eat. The only food here is wretchedly um-nourishing, bark, moss and lichen. They are hardly enough to sustain one monkey, let alone a family.? But they share it, peaceably. Survival depends on the group keep together. In these mountains, any food is precious. Rivals, they too are searching for food. The two males go head to head. Now the females join the fray. Outnumbered, the intruders retreat. Their leader is the last to go. The fight was over the smallest of meals, but it was ferocious nonetheless and the family is now scattered. But they must stay together. The youngest are already badly chilled. She can see her father, but has she the strength to reach him. Back to safety and warmth. The huddle is the only source of warmth in these bleak frozen forests.
To the west of the Himalayas in Iran, lie some of the hottest deserts on earth. This is the Lut Desert and here temperature can reach 70 degrees Celsius. The blisteringly hot rocks and baking sands of Iran’s deserts may appear totally lifeless. But a few trees manage to grow in the shade of the canyon walls. And here at least, migrating birds passing through, can stop for a little rest. A flycatcher. With luck, there might be a meal of some kind here. There are spiders in the crevices. Not much but worth having. And there is something moving up there. The bird was mistaken. It was a viper with a lethal bite.? This species has only recently been discovered, and so far, it has been found nowhere else but here. Its camouflage is so effective that it is almost impossible to see it on these rocks. And on its tail, moveable scales have been modified to look like a spider’s legs. And its tip, like an abdomen. Migrating birds only appear in this barren desert during a few weeks of the year. This is the snake’s only chance to eat for months! A shrike. It was flown here from Africa and hasn’t fed for days. Better luck next time.
Conditions are almost as harsh on the dry plains of Northern India. A male Sarada Lizard does his best to get himself noticed. It is breeding time. The wide-open spaces are good place to be seen. He is only 7 centimetres tall, but a rock will help to make him conspicuous. And he has already been noticed by one female. It’s time for him to show off. The more healthy and virile he is, the brighter his colours are.?And females like bright, flashy colours. But he, it seems, is not as conspicuous as he might be. In the neighbor territory, there is another male who has found an even bigger rock. So the newcomer is not making quite such a good impression. The one on the big rock is attracting all the females. A newcomer will need a higher platform if he is to been seen by a female and he had better do something about it. He only lives for a year. This is his one chance. He will have to fight if necessary. His rival isn’t backing down. Sarada males can fight to the death. The newcomer has won. Now he can claim the high platform and the best territory. And the females will choose him for a partner as long as he can fight off the other claimants.
As the Himalayas rose over millions of years they eventually formed a gigantic barrier that prevented rain clouds from the south travelling further north. And a completely new weather system developed in southern Asia. The monsoon.
These drenching annual rains transformed southern Asia. Dense rain-forests?formed in which plants and animals of all kinds were able to proliferate and evolve. Some of the tallest jungles grow in Indonesia. The home of the largest of all tree-living animals of any kind, the orangutan. There is multitude of things to eat here, but you have to know where to find them. Young orangs stay with their mother for years learning how to do that. This youngster has only just started. Termites, an important source of protein. But perhaps they are an acquired taste. He’s off to search for something he might prefer. It’s hard to know where to look. Or where is safe to clamber. Different levels in the forest contain different foods. And some of them the most delicious are in the highest parts of the canopy. 50 metres above the ground. He is a couple of years old, and he is already getting adventurous. His mother could climb right to the top in ten minutes or so if she wants to. But she lingers to keep an eye on him. A fall from this height could be fatal. Where the gaps between the branches are too wide for him, his mother lets him use her body as a bridge. Only 10 metres to go before the top, but it’s hard for a small hands. He’s had enough. Time for a rest with mother. And this is his reward, ripe mangoes sweet and juicy. There is so much he must learn. He will depend entirely on his mother until he is seven. It is the longest of all childhoods except ours.
In these dense forests, it is not easy for animals to see one another at any distance. But songs carry well through the jungle. This is the characteristic sound that echoes through the Sumatran forest at every dawn. But what can this be? Of all the sounds in the Indonesian forests, this is one of the strangest to our ears. It can be heard nowhere else on earth. And this is the singer. A Sumatran rhinoceros.
She is tiny, only a fifth of the size of her more Africa relatives. Her head could rest?comfortable on your knee. She is the gardener of this Eden. She doesn’t just live in it, she?helps to create and sustain it. She eats fruits and then sheds the seeds in her droppings and so spread the foods she prefers through the forests. In this dense jungle, she uses sound to locate a possible mate. But her calls are unanswered. She is living behind a fence for her own protection. In the past, Sumatran rhinos were widespread through Southern Asia. Today, there are fewer than 70. It may well be that as she approaches the end of her natural life, she will have become one of the last of her species. Because in the last 40 years, one third of the forests of Southeast Asia has been destroyed in order to sell timber and food products around the world. The forests of Borneo and Sumatra home to the orangutan and rhinos and thousands of other species that have evolved here over millions of years are now in real danger of being lost forever. It seems that the animal whose home this once was are worth to us than the land they lived on.
Viewed from space, the scale of destruction is only too obvious. Asia has undergone a faster change in the last 100 years than at any time in its history. Its forests are being annihilated. Its cities are expanding and as the human population approaches 4.6 billion, the largest of all continent is no longer able it seems to allow space for its wildlife.
The ocean around Southern Asia are also feeling this pressure. These seas feed billions of people around the world. For many fishermen here, their catch is the only source of livelihood. And there is one fish here that they prize above all others. The whale shark. It swims slowly, gently harvesting the plankton. It is almost 20 metres long, the largest fish in the world. They are also under the threat. Like many shark species in Asia, populations have declined by more than half in recent years. They are an easy and valuable catch. But here, there is a respect for the seas and their inhabitants. Whale shark hunting has now been banned across Indonesia waters. This whale shark plays a different part in the lives of these fishermen.?They feed him, and relationship seems to bring joy to both parties. And with this new protection has come something truly remarkable. Whale sharks from far away are seeking out these fishermen. And in these safe waters, there is a chance for their numbers to increase. And may be one day, other sharks species will be protected too.?The people here have made a simple and extraordinary choice, fishing in a way that is sustainable for themselves and the animals. Caring for wildlife is surely our shared responsibility. Across this vast continent and across the world, it is decisions like these that are key to protecting the planet’s most precious diversity.
Asia on location（亞洲拍攝后）:
I first went in search of orangutan in 1956. Then there were around 175,00 living in the remote forests of Borneo. I found on the forest floor, the rinds and cores of durian fruit which I knew was the favourite food of orangutan. Then we heard a crashing in the branches ahead, and high up in the trees, we saw a great furry read form. He seemed enormous and was probably five feet high. In the sixty years since, I’ve returned to Borneo on many occasions to film and document its wildlife. But during that time, the islands’orangutan population has more than halved, leaving them endangered, and finding them in their natural habitat has become ever more difficult. The cause of this decline was evident during the visit in 2012.
When I first came to this river in Borneo in 1956, the rainforest stretch unbroken on either side of the side for hundreds of miles, but it’s very different today. Now only patches of forest remain, so to film orangutan in the wild, the Seven Worlds crew joined a research team heading for the Gunung Palung National Park. This four hundred square mile area is home to Borneo’s largest remaining wild orangutan population. Here, they are protected and studied.
The crew follow a mother, known to researches as Bebe and her infant Bias as she teaches him how to find food. Like all orangutan mothers, Bebe has to work hard to raise Bias and this means she may only have four or five infants in her lifetime. This low number of babies means it is hard for orangutan to recovery from population decline. Researches want to know why orangutan give birth so rarely. Today they’re following a young female Walima to find out if she’s pregnant, but to do this, they’ll have to put themselves in the firing line.
Dr Cheryl Knott says, “So what we do is to wait until she pees, and we have a bag on fishing pole, and when she starts to go, we run under there and we try to catch it. Yeah, a few years ago I was featured in a magazine as the top ten worst jobs in the science-it was kind of a joke, but orangutan pee collector was number one. So not too glamorous apparently.”
Research is starting to show an important pattern: the orangutan can only conceive when there is enough fruit around their home. The team will now test the sample to discover if Walima is pregnant. But the orangutan within Gunung Palung are the lucky ones.
Those beyond the borders of the park face a very different world. Many are left with no home at all. This footage shows members of International Animal Rescue attempting to dart and sedate a stranded orangutan so it can be moved to safety. Rescued orangutan are treated, but with each passing year, there are fewer places left for them to go. The destruction on Borneo’s rainforest has been happening on an industrial scale. Huge areas were initially stripped for timber and then a very different type of tree were planted, oil palm. Today it has become the most widely used type of vegetable oil in the world and Borneo is the location of almost half the oil palm plantations on the planet. These uniform plantations can’t support life in the same way as a rich and diverse rainforest. However, oil palm is very important to the local economy and it’s highly efficient. Simply using another type of oil might take up more land leading to more deforestation.
And this is where it ends up palm oil is found in around half the package products in our supermarkets as well as in bio-fuels. The balance between our needs and conservation is hard, but we can offer a vital lifeline for our forest relatives. We may be able to protect them through simple choices life buying products made with deforestation-free sustainable palm oil from companies that support local people using existing plantations without cutting down more rainforest, keeping Gunung Palung’s inhabitants safe including Walima who did become pregnant and now has a daughter to care for. Their future will be determined by the choices we make today.
Back in 1956, I never imagined that within the space of my lifetime, these intelligent apes and the ancient forests they have lived in for millions of years would be placed under such dire threat. Just how much longer they will inhabit the planet is up to all of us.
