00:00In the north of the Himalayas, there is a land few times seen by the outside world.
00:16The Tibet plateau.
00:21It covers 25% of China and is the highest and most extensive plateau in the world.
00:31Here, the animals are pushed to the limit of their possibilities.
00:38Some dedicated parents fight to bring their sheep to these steep peaks.
00:46A young monkey faces the family plots in the forests of the slopes.
00:51And brave Tibetan antelopes undertake an epic migration to produce life while they face death in the high plains.
01:10All the animals that inhabit this place fight daily to survive.
01:19But only the strongest survive in this land of extremes.
01:25Here, at the top of the world.
01:32Tibet, the top of the world.
01:35This story begins in the forest, on the edge of the plateau.
01:54Right now, it is under the iron rule of winter.
01:59A time when temperatures never rise above zero degrees.
02:04Enduring as best he can among the trees, he finds one of the rarest primates in the world.
02:17There could be less than 2,000 specimens left in freedom.
02:23It is the black langur with a flat nose.
02:27No other monkey on the planet lives at greater altitude.
02:34They are specially adapted to life at these altitudes.
02:40The absence of a nose allows the air, poor in oxygen, to have a direct entrance.
02:47And thus, it does not run the risk of losing it by freezing with extreme cold.
02:56The thick fur protects them to a certain extent.
03:00But what really helps them survive here is to have each other.
03:07This little one is in the safest place he could be.
03:13Cuddled in the arms of his abnegated mother.
03:23His father has spent the summer very busy protecting the sand.
03:27But now he contributes to heating the tight family core.
03:34This little prince has been the center of his mother's attention since he was born last year.
03:40But his world is about to take a total turn.
03:45At the top of the wooded slopes are the peaks of the mountains.
03:51At an altitude of about 5,000 meters, it is the highest and steepest part of the Tibet plateau.
03:57Up here, there is only half as much oxygen as at sea level.
04:07There is no other way to get to the top of the mountains.
04:13The only way to get to the top of the mountains is by boat.
04:19The only way to get to the top of the mountains is by boat.
04:28It is too cold for most mammals.
04:32Although not all.
04:47A Tibetan wolf.
04:50One of the rarest wolves in the world.
04:54His domain extends through this rugged terrain.
05:02But the territory means nothing if it does not produce food.
05:07And he is hungry.
05:10I have here what I was looking for.
05:13Barrels.
05:18It is difficult to distinguish them in this immense space.
05:23It is difficult to distinguish them in this immense space.
05:31He can not do it alone.
05:41But he has help.
05:54The herd must work as a team.
06:11Its blood, adapted to transport more oxygen, gives it resistance.
06:16But there is a lot of ground to cover.
06:23They have detected the trail of the barrels.
06:27Their targets are already in sight.
06:35The hunt begins.
06:43The barrels run away to a more rugged terrain,
06:47where the wolves cannot follow them.
06:50A member of the herd passes them to keep them away from the rocks.
07:10Teamwork has paid off.
07:21A prey of this size will give them food for several days.
07:30But soon they will have to look for more prey.
07:35From the top of the food chain to the lowest.
07:43Pikes, cousins close to rabbits.
07:46They are too focused on food.
07:50Even in winter, under the blanket of snow, it is still possible to find grass.
07:56If you are willing to dig.
08:03They outnumber all the other mammals.
08:06And they are on the menu of all the predators of the highlands.
08:11The entire ecosystem rests on these small and furry shoulders.
08:20Luckily, they have a safe space.
08:24They have a safe place to rest.
08:28They have a safe place to rest.
08:32Luckily, they have a safe place to rest.
08:38Each family has its own burrow,
08:41with separate rooms and multiple entrances.
08:47A shelter from danger and cold.
08:53Suddenly, an uproar.
09:02They are yaks.
09:04A relative of the cows with long hair.
09:13They are transhuming with their shepherds.
09:19They are able to live at more than 5,000 meters above sea level.
09:23Something that almost no other domestic animal can do.
09:31Now they are thirsty.
09:39But in winter, this is one of the driest places in the world.
09:47Practically all the water is trapped in the snow and ice, even in this river.
09:55But the yak has a special technique to free it.
10:02First, it must face the ice.
10:07A difficult challenge for an animal that weighs as much as half a small car.
10:32They are not exactly skaters.
10:35And this is their secret weapon.
10:39It melts the ice a little,
10:42and then it turns it into water.
10:47It is a secret weapon.
10:51It is a secret weapon.
10:55It melts the ice a little,
10:58and then it turns it into water.
11:01It melts the ice a little,
11:04and then it turns it into water.
11:11An ingenious survival strategy.
11:16They will not need to drink again in a couple of days.
11:21Their fur is thick enough to keep the body warm,
11:25even if it freezes on the surface.
11:28These impressive animals are made to thrive here.
11:43Finally, winter ceases to threaten the forest on the slopes,
11:47and spring begins to appear.
11:58For the little monkey, everything is a continuous change,
12:02and life cannot be better.
12:06He is old enough to experiment with total freedom.
12:16Life is a great adventure.
12:28And in each tree, there is a playmate.
12:32But spring brings another novelty.
13:02A little sister.
13:22Like all babies, her sister is a nuisance,
13:26and takes all the attention of her mother.
13:33After a day full of adventures,
13:36the little prince returns to his family.
13:48But his mother is busy.
13:56He is no longer the center of attention.
14:03His perfect childhood vanishes for a moment.
14:15It seems that he will have to take care of himself.
14:23The signs of spring are rising little by little.
14:28Until they finally reach the high peaks.
14:46But up here, the snow takes a long time to disappear.
14:51The wolves have managed to overcome winter.
14:55Even so, their life ahead will not be easier.
15:00Getting food is even more important now.
15:10The alpha female has been a mother.
15:15And she has four little mouths to feed.
15:30The future of this rare species of wolf rests in puppies.
15:35And it is time to give them a new life.
15:44Puppies like these, and right now,
15:47their mother's milk is the only thing that keeps them alive.
16:00With a full stomach,
16:02the most daring puppy begins to investigate his world.
16:09And he pushes his brothers to do the same.
16:15Even with certain abusive tactics.
16:20Through these tricks,
16:23the puppies gain strength and coordination,
16:26which are fundamental skills for hunting.
16:32Soon the peaks of the place will be in their sight.
16:39While the puppies continue to hunt,
16:42their father and the rest of the herd have a task ahead.
16:47With new mouths to feed,
16:50the territory is more important than ever.
16:55They work in groups to claim their areas,
16:58sending their competitors the unmistakable message
17:01that this territory belongs to them.
17:06Territory means food,
17:09and with the arrival of May,
17:12it begins to become more abundant.
17:16For the varal, it is breeding season.
17:25Varals depend entirely on the steep peaks
17:28to protect themselves from wolves.
17:40Puppies must learn very soon
17:43to move through these dangerous terrains.
17:53These animals are perfectly adapted to this vertical world.
18:00The varal has a lot in common with the goat.
18:04Like the goat,
18:06it has a split nipple to better grip the rocky surfaces.
18:11Its soft soles work like climbing shoes.
18:17They almost seem to challenge the force of gravity.
18:26Wolves could never reach them up there.
18:30But there is another enemy
18:35that also feels comfortable among the cliffs.
18:40The snow leopard.
18:44Its weapons are stealth and camouflage.
18:47It waits for its prey to get close enough
18:50to catch it by surprise.
18:54But the varals stay out of its reach.
18:58Today it will starve.
19:07Like the wolves, it needs to defend its territory.
19:14But unlike the snow leopards,
19:17the snow leopard is not afraid of danger.
19:23Unlike them, this female works alone.
19:29The odour glands around the moustache and the chin
19:33spread their scent
19:36and leave a clear message to other leopards.
19:39Get out of here!
19:46As the month of May advances on the plateau,
19:49the pikes' families grow rapidly.
20:00The father has already started to produce herds.
20:04From now until the end of the summer,
20:07he and his wife could have a litter every three weeks.
20:11Therefore, they would produce up to 18 young this season
20:15and all of them will have to eat.
20:20The territory of the father is not larger
20:23than a few parking spaces,
20:26but he defends it at the expense of everyone who approaches.
20:34Dad has detected an intruder.
20:39He comes in search of the food that produces this land.
20:45And dad is not going to let him.
20:50The warning does not work.
20:58And the fight begins.
21:08Although he is small, he fights like a brave man.
21:12Although he is small, he fights like a brave man.
21:33He has defended his little kingdom.
21:37However, close to there he faces a much greater danger.
21:42A royal eagle with the pikes in its sight.
22:04Warning call.
22:08Most catch the message.
22:13But one has been exposed in open terrain.
22:22Wrong place, wrong time.
22:34The father and his family have passed another difficult test.
22:43The highland extends between the high peaks.
22:51Here, with the arrival of spring,
22:54begins the most epic event of the Tibetan plateau.
23:06The migration of the Chirúes, the Tibetan antelopes.
23:12Thousands have traveled up to 300 kilometers in the last three weeks,
23:17from all corners of the plateau.
23:30They are females who have left the males behind
23:33and will not see them again in several months.
23:42This is their promised land.
23:47The coasts of the mystical lake Suonai.
24:02Nobody knows why they have chosen this particular place,
24:06but they are here for a very special reason.
24:09To continue the cycle of life.
24:17All the females of the pack stop in just three weeks of July.
24:30There is no time to stay without doing anything.
24:39They have to be able to walk for 15 minutes before being born.
25:03Incredibly, the young are already able to walk at the age of 15 minutes of birth,
25:08and luckily, such an abundance of possible prey
25:12inevitably attracts predators.
25:21Another group of Tibetan wolves, waiting for their opportunity.
25:26They will have to act soon.
25:32The Chirúes will definitely leave when the summer ends.
25:39But for now, their journeys are shorter.
25:43Every night, all the mothers and their young
25:46move to the nearby hills,
25:49fleeing the exposure in the plain.
26:02While the Chirúes are getting ready to go to bed,
26:06the darkness invades the entire plateau.
26:10At more than 4,000 meters above sea level,
26:13at night the temperatures plummet, even in summer.
26:20At these altitudes, the same sky seems like it can be touched.
26:37The Chirúes are already in their prime in the forest.
26:42The young male has stopped depending on his family
26:46since his sister arrived.
26:49But it is a good time of the year to make friends.
26:53The Chirúes are already in their prime in the forest.
26:57The young male has stopped depending on his family
27:01since his sister arrived.
27:04But it is a good time of the year to make friends.
27:13They seem to be having a good time.
27:16These young males left their families when they were their age.
27:21They have formed a gang,
27:23and are practicing skills they need to master.
27:35If he wants to follow in his father's footsteps
27:38and lead a gang one day,
27:40he will have to learn to fight.
27:49He can no longer resist the urge to join them.
27:54But the others practically double his size.
27:58But the others practically double his size.
28:02And soon he realizes his mistake.
28:24His mother has heard his cries.
28:36It turns out she was watching him.
28:46He has no serious injuries,
28:49except in his pride.
28:52He probably needs his family more than he thought.
28:56He probably needs his family more than he thought.
29:03At the top of the peaks, it is already summer.
29:12But the Tibet continues to test the wolves.
29:20The puppies are hungry,
29:22and their mother's milk is running out.
29:26Father has not yet returned with food,
29:29and mother can only hunt in the vicinity of the burrow.
29:35Time is running out.
29:37He needs to get food.
29:45Suddenly, they see something.
29:50A wolf!
30:04It is father,
30:06and he comes with a surprise.
30:10Food for his hungry family.
30:16They start eating meat very early,
30:19about three weeks old.
30:22Soon they will no longer need a drop of mother's milk.
30:40Now, without hunger, it is time to play,
30:44and practice more hunting skills.
30:48These game sessions at the end
30:51will decide the hierarchical order in the family.
31:10All the young people who live in the highlands
31:13enjoy the relatively warm days of summer to the fullest.
31:24There is plenty of fresh grass,
31:30and plenty of time to play,
31:33and, in passing, to become strong for the challenges that await them.
31:39There is always something to do.
31:45The sun shines,
31:48and the wind blows.
31:51The grass is green,
31:54and the wind is blowing.
31:57The wind is blowing,
32:00and the grass is green.
32:03The grass is green,
32:06But good times do not last forever.
32:31One of the largest meteorological phenomena on the planet is approaching.
32:37It barely rains on the arid plateau of Tibet until the end of July,
32:43when the winds and rains of the monsoon appear.
32:49The monsoon advances to the north from India and the south of Asia with such force
32:55that not even the mountain range of the Himalayas and its imposing Mount Everest can stop it.
33:05The storm covers the entire forest
33:11and closes on the shores of Lake Suonai.
33:22Here the situation gets even more complicated.
33:28At an altitude of 4,000 meters, the rain falls in the form of ice.
33:36In these open plains, the chiruas depend on their thick outer fur to repel the hail.
33:46The soft and warm fur they have underneath was at a time so coveted to make luxury coats,
33:54that this antelope was on the verge of extinction.
34:02Today it is a protected species, and its biggest problem is extreme meteorology.
34:17Finally, the storm ends, but it has left its mark.
34:27The monsoon has turned this river into a torrent.
34:35Even so, the herd must cross it every night to go to its refuge in the hills.
35:06It is not easy with such thin legs.
35:10Many of the young have only two weeks to live.
35:36The experienced mothers try to protect their young,
35:43but when the water runs so fast, crossing is still dangerous.
35:51Staying behind can have fatal consequences.
36:06The strength of the water is excessive for some.
36:23Others have difficulties.
36:30Exhausted from the effort, they still have to overcome the last obstacle, which is to get out.
36:43The little ones have passed their first big test.
36:52The instinct drives these mothers to seek refuge for the night,
36:59and their young cannot do anything but follow them.
37:07But the summer monsoon in Tibet has not yet ended here.
37:13The clouds, still full of moisture, advance towards the surrounding peaks.
37:32Here, the temperature in summer can drop 20 degrees in one day.
37:39And at these altitudes, the rain becomes blizzard.
37:46Adult wolves are used to these extreme weather events,
37:52but their young need protection.
37:55Their dedicated parents keep them safe in the burrow while the storm lasts.
38:04As soon as it appears, the snow melts again.
38:13The sun rises on the plateau, and the chirus return to their usual feeding grounds.
38:26The wolves stalk the herd.
38:32Soon there will cease to be this abundance of prey,
38:38when the chirus leave for their winter territories.
38:44The opportunities for the wolves are over.
38:50And they take action.
39:21The adults are very fast.
39:28They need to attack the younger ones.
39:41The chirus gather in search of safety.
39:48But the predators are not willing to give up.
39:54Now or never.
40:17The wolf manages to get between the mother and the calf.
40:47It is impossible for it to defend itself from a hungry wolf.
40:53Another pair of young are separated from their mothers.
40:59One of them has no escape.
41:05The other is trapped in the burrow.
41:11One of them has no escape.
41:17It is lost.
41:23The other has managed to return to the herd's safety.
41:29This time, the balance has tilted in favor of the wolves.
41:35But the chirus herd has not given up.
41:41It has not given up.
41:48But the chirus herd remains strong.
42:02In the forest, the change of season has already begun.
42:09Autumn brings new dangers for the monkeys.
42:25The little male survives alone.
42:31When something catches his attention.
42:37A great male, unknown, that rests in confidence.
42:43He is in the middle of a mission.
42:49He is in the middle of a mission.
42:55The little male feels curious and decides to follow in his footsteps.
43:18Suddenly, he sees his mother and her calf.
43:24He sees his mother and his sister.
43:30And he understands the intentions of the great male.
43:39It is breeding season, and he has the mission of looking for a mate.
43:45The father hears the commotion and rushes to defend his females.
44:15The intruder tries to escape.
44:20But he will not get away so easily.
44:25The mother runs to safety.
44:33This time, the intruder leaves.
44:40But he is injured. It will take a while to return.
44:46But he is injured. It will take a while to return.
44:52The father has protected what is his.
44:58He is not a monkey to be confronted with.
45:04But he has learned a great lesson.
45:10Not everyone who wanders around here is a friend.
45:20Bad times are coming.
45:34But for now, the efforts of the snow leopard to protect its territory have paid off.
45:40But for now, the efforts of the snow leopard to protect its territory have paid off.
45:46With the ram, he will be able to hold out for a few days.
45:52The efforts of the wolves have also been worth it.
45:58The alpha male has shown that he is a good head of family,
46:04and with this food, he has earned the respect of others.
46:10The alpha male has shown that he is a good head of family,
46:16and with this food, he has earned the respect of others.
46:30Adding to their strength, these wolves have raised four healthy puppies.
46:36Soon they will be fully developed hunters like their parents.
46:43But the tibetan is about to change again.
46:58In the woody slopes, the temperature is starting to drop.
47:05The little male is now literally abandoned in the middle of the cold.
47:11Without the warmth and care of his family, he will not survive.
47:17Without the warmth and care of his family, he will not survive.
47:23The sister sees that she is looking at them, and her reaction is surprising.
47:29The sister sees that she is looking at them, and her reaction is surprising.
47:35She approaches her older brother with caution.
47:41She approaches her older brother with caution.
47:47They share a moment.
47:52Her sister, who had made him feel rejected upon his arrival,
47:58is now ready to reunite with her family.
48:04And just in time, because in the tibet, the arrival of winter is almost instantaneous.
48:13Chirú's young are already stronger, and they should be.
48:19They have a long journey ahead to their winter territories.
48:25In a few days, they will all be gone.
48:31They arrived as a herd, but they leave as families.
48:40The pikes stay where they are, enduring the winter.
48:46The wolves also stay, and pick up everything that the tibet puts in their path.
48:55The monkeys prepare for the harsh winter, knowing that they have each other.
49:03These heroic creatures bring their families forward in the worst conditions,
49:09and they do it year after year.
49:14A new generation is now ready to face the future,
49:20and continue the endless cycle of life,
49:25here, at the top of the world.
