TVTranscript
00:02For a small country barely the size of Switzerland, Costa Rica has made tremendous efforts to protect the environment,
00:10setting aside one-fourth of its land area as natural parks and nature reserves.
00:16The tropical climate and varied topography have fostered exceptional biodiversity,
00:21with wildlife from both North and South America.
00:24From the peaks of volcanoes down to the Pacific and Caribbean shores, wildlife has flourished.
00:57Costa Rica is located midway on the isthmus that has joined the two continents North America and South America for
01:0415 million years.
01:05The east-west collision between two tectonic plates, the Caribbean plate to the east and the Cocos plate beneath the
01:12Pacific Ocean to the west,
01:14has created this narrow strip of land dominated by the perfect cones of its many volcanoes.
01:22Many of these volcanoes are active, while others are dormant.
01:27The continuing tectonic activity has formed a chain rising to an altitude of 3800 meters.
01:34Ocean winds drive the warm, damp air up from the plains and onto the slopes.
01:40The rising vapor cools, and as it cools it condenses into clouds.
01:45Between 1,000 and 3,000 meters, the climate has produced a biotope typical of tropical mountain areas, the cloud
01:54forest.
01:58The tallest trees form a canopy some 20 meters above the ground.
02:03Lush vegetation with twisted trunks and contorted branches covers the entire area.
02:10All along the mossy trunks, plants stretch skyward, rising from darkness, seeking light for photosynthesis.
02:26Warm springs are a reminder that we're on the edge of a volcano.
02:34The remarkable turquoise color of the river is a natural phenomenon, due to the chemical reaction between calcium carbonate and
02:42the sulfur in the water from deep underground.
02:44The entire area is filled with the stench of rotten eggs.
03:01But everywhere in the cloud forest, water is indeed the source of life and the key to luxuriant plant growth.
03:10Overcoming the lack of space on the crowded forest floor, some plants, called epiphytes, like orchids and lichens, grow on
03:18the surface of trees without reaching the ground.
03:21They gather minerals from the humus that builds up at the bases of branches, and they filter rainwater.
03:28Between the ground and the top of the canopy, there is a full range of vegetation levels.
03:34Every large tree is an ecosystem in its own right, providing a great variety of habitats and food for the
03:41animals of the forest.
03:44The black-faced solitaire builds its nest in moss, half-concealed by the vegetation.
03:52This male sings to keep in contact with his mate.
03:59But there's another song in the air.
04:05One of the loudest, most penetrating songs in the cloud forest comes from the three-waddled bellbird.
04:12The male's head features three wattles of skin, and his beak opens wide.
04:18The bellbird is mainly a fruit-eater, but it could intimidate many a smaller creature.
04:27The bellbirds and other birds living in the cool cloud forest are often reclusive and hard to see.
04:35On the other hand, there's no problem watching the many species of hummingbirds
04:40when they display their plumage with its characteristic metallic sheen.
04:54Bright-colored passerines, like this couple of flame-colored tanagers, have to beware of birds of prey.
05:03Luckily for them, this turkey vulture is a carrion bird.
05:07And even if it's hungry, the tanagers would be far too fast for any vulture to catch them.
05:22It should come as no surprise that these mysterious forests are home to one of the world's most beautiful birds.
05:29Watch the long green tail feathers protruding from a hollowed-out tree trunk.
05:33These mountains are home to the mythical resplendent Quetzal,
05:37once considered divine and now classified as near-threatened.
05:42The female, recognized by her short tail feathers and gray breast, is not far from the nest.
05:48Inside, the long green tail feather shows the male is at work.
05:57The female immediately flies in to replace her partner in warming their two hatchlings, who are only a few days
06:04old.
06:05The male can shake out his feathers before flying off to hunt.
06:15The female watches for the father to return, when she'll have to leave, as the nest is too small for
06:21the both of them.
06:23About ten minutes later, the male is back, with a grasshopper in his beak for the chicks.
06:27They'll need a few more days before they can eat fruit like their parents.
06:39In the meantime, the female Quetzal can rely on her partner, who conscientiously carries out his fatherly duties.
06:48At 2,000 meters in altitude, another couple of Quetzals is ready to mate.
06:54The nesting season runs from April to May.
06:58If they are perching side by side outside the nest, it's because the male is still working on the nest.
07:03He hasn't finished hollowing out the trunk of a dead tree to make it more comfortable.
07:08The female is quite demanding, and won't accept the nest until it's absolutely perfect.
07:48The female checks on how the work is coming along.
07:51Will she approve the nest and finally take possession?
07:59The male has worked hard and looks exhausted.
08:08But his partner has flown out, signaling there's more work to do.
08:18So the male bravely resigns himself to finishing the job.
08:32The female Quetzal remains unruffled, confident of getting her way.
08:37This is surely a part of their mating game.
08:47Throughout Latin America, the resplendent Quetzal is a symbol of freedom.
08:51Every attempt to raise Quetzals in captivity has failed.
08:57Quetzals allow themselves to die if deprived of their freedom.
09:01Preserving the Quetzal means preserving its natural habitat.
09:05Creating ecological corridors to link forests together would also promote greater genetic mixing between populations.
09:18The cloud forest is home to many other intriguing species.
09:23What is this strange thing that looks like a furry snake poking around in the underbrush?
09:31It's the tale of a white-nosed coati.
09:40Coatis are omnivores.
09:43They're quick and clever and constantly in search of food.
09:47This one's foraging under the leaves for small vertebrates, insects, nuts and fruit.
09:53And nothing will distract him.
10:02Their excellent sense of smell helps them locate their prey, no matter how small or how well they're hidden.
10:09Their sharp claws do the rest.
10:21Coatis find most of their food on the ground, but they're ready to climb the trees as well.
10:27The best fruits might demand more of an effort, but coatis have perfect balance.
10:37Male coatis tend to be solitary, except during the mating season.
10:42But females live in small family bands with their young.
10:46This social structure provides protection for the young pups,
10:50despite the fact that adults are constantly caught up in the search for food.
11:05Because of their mobility and voracious appetite, coatis play a major role in the ecosystem.
11:11After digesting fruit from the trees, they disperse the seeds far away.
11:16Some seeds germinate better after transiting through their digestive systems
11:21and being dropped to the ground with natural fertilizer.
11:25This is one of nature's ways of spreading the forest and promoting plant biodiversity.
11:36The smaller trees are frequently visited by variegated squirrels, so-called because of their multicolored fur.
11:44Unlike squirrels in other countries, variegated squirrels do not store food for later,
11:50because there's no winter in Costa Rica.
11:53There's a dry season, when it still rains, and a rainy season, when the sun still comes out.
12:01In short, because there's never a season without a fresh food supply,
12:05there's no reason to store food for later.
12:10This also means that forgotten stores won't germinate to form new trees,
12:14as can occur in Europe or North America.
12:23Some of the most remarkable trees in the forest are the various species of strangler fig.
12:29They begin as seeds dispersed by birds and germinate on other existing trees.
12:35They grow branches to capture light and send their roots down to the ground, wrapping around the support tree.
12:42This strangles the host tree, which eventually dies and decays, leaving a baroque-shaped columnar tree around a hollow core.
12:54These tall trees make perfect purchase for mantled howler monkeys,
12:59so named because of the loud calls they use to communicate and defend their territory.
13:32These impressive calls can be heard from miles away,
13:35when they grow up.
13:39The sound is amplified by the hyoid bone near the vocal cords,
13:45which is enlarged in the male mantled howler.
13:52Any conflicts among the mantled howler monkeys are handled simply by howling.
13:57At the very least, this spares them the need to fight.
14:02This monkey tends to be pretty lackadaisical,
14:06largely owing to their diet,
14:08which is primarily composed of leaves that have low nutritional value and are hard to digest.
14:23They prefer tender shoots, which are less likely to contain toxins.
14:29But first of all, they have to reach the shoots.
14:46Mantled howler monkeys spend the rest of their time napping.
14:55Despite the damp midday heat, the young howlers have the time and energy to play.
15:03The rules are simple.
15:05Just hold on and try not to fall.
15:08Let's go!
15:09Let's go!
15:11Let's go!
15:25Let's go!
15:41Heliconia, this flower plant that grows in forests, is highly nutritious and rich in
15:47glucose.
15:48It's a feast for this hummingbird, a white-necked jacoban attracted by its red petals.
16:11During the day, hummingbirds have to feed every ten minutes or so, and their daily sugar
16:16intake has to be roughly half their body weight.
16:20That's because of their rapid metabolism.
16:22With a heart beating nearly 1,000 times a minute, without food, a hummingbird would die
16:29in less than two hours.
16:40When the rain begins to fall, filling the flowers' corollis with sweet water, the feast becomes
16:47even more intense.
16:52Hummingbirds could add more protein to their diet, but the small insects they'd have to
16:57catch tend to vanish when it rains.
17:17Between two wheels, hummingbirds perch in order to conserve energy.
17:22They can fly backwards or hover in place.
17:25This helps them avoid collisions when several are attracted to the same flower.
17:31hummingbirds could add more.
17:43Yet, while they can weigh less than 10 grams soaking wet, a hummingbird's life is an extremely
17:50active one.
17:53The other birds seem to dislike the rain and take shelter as they wait for the sky to clear.
18:00But the rain can continue for days, and they simply have to feed.
18:06The smallest passerines, like this olive-backed euphonia, have no choice but to face the rain.
18:14This male, red-legged honeycreeper is all decked out for the mating season and can't resist
18:21the temptation of a bunch of bananas.
18:24In the heat and rain, fruit spoils as soon as it ripens.
18:28Birds have no trouble breaking the soft skin.
18:31The most aggressive birds, like this blue-gray tanature, manage to get the best spots.
18:43The cloud forest gets over two meters of rainfall a year, making it a paradise for frogs.
18:53This green and black poison dart frog, like other members of the family Dendrobatidae, have
19:00brightly colored bodies to warn potential predators that they are toxic.
19:05The poison in their skin is only defensive, and is secreted only when they are under stress.
19:12Still, the toxin is strong enough to kill a man.
19:15One hypothesis is that Dendrobats accumulate poison from their prey, especially ants and centipedes.
19:26And then, suddenly, the rain stops.
19:32Even weak wide when they all of the bugs don't deal even, teeny, or the嗯.

20:16The Sun
20:17is greeted by a multitude of bird songs. But this blue-throated Toucanet has no time
20:27to join the symphony because he's totally focused on feeding his chicks and their mother.
20:33The female hollowed out the nest. She's currently incubating four eggs, and it's the male's turn
20:39to feed the family.
20:48He flies between fruit trees and the nest, removing waste matter during each journey.
20:57Keeping the nest clean is essential because the couple will be using it for many years to come.
21:20A little lower at an altitude of 1,200 meters, the temperature climbs swiftly with the Sun.
21:26This is when the male cicadas sing, or rather make a strident sound by vibrating their timbles,
21:33which are membranes on their abdomens.
21:37The males have recently molded, casting off their exuvia, and now they're trying to attract females.
21:43Without this distinctive sound, how could they find the right mate among the 35,000 known species
21:48of insects identified in Costa Rica?
21:57While beetles with their flashy colors are easy to see, some grasshoppers are perfect at camouflage,
22:04as they seek to remain invisible to predators.
22:11Sometimes, it's the other way around, with brightly colored prey and a well-camouflaged predator.
22:18Like most dendorbrats, the blue-jean's dart frog is poisonous, and so has no reason to be discreet.
22:26Indeed, to attract a mate, the male's approach to courtship seems to be the same as the cicadas.
22:34The louder, the better.
22:41In the jungle, you have to do everything you can to get attention, when you're barely two centimeters long.
22:54A little further, a young nine-banded armadillo is already wide awake.
22:59This nocturnal animal is really hungry as it emerges from its burrow in the twilight.
23:07Guided by a powerful sense of smell, it's searching for earthworms, small reptiles, and especially insects.
23:15Discovering an ant hill wets its appetite even more.
23:19Fortunately, it's protected from ant bites by its caratine carapace and the thick skin of its belly.
23:32Lower down, at an altitude of 1,000 meters, the cloud forest gives way to a sunnier, warmer biotope.
23:39This is the tropical rainforest.
23:42Here, annual rainfall does not exceed 2 meters, and during the dry season from December to April, the sun may
23:50shine several days in a row.
23:55Here, too, sulfur tariffs are a reminder of the volcanic origin of the subsoil.
24:00The continuous emission of hydrogen sulfide from these vents has scarred the vegetation.
24:10But the sulfur carried by the water settles quickly near the source, and the clearer water, downriver, can irrigate the
24:18forest.
24:26Abundant water and generous sunlight have led to a unique variety of plants.
24:33The flowering trees burst into bloom, each in turn as the seasons change.
24:42Plants of the bromeliad family, which often grow on other trees, have large flowers with a huge variety of colors
24:50and shapes.
24:54With 1,200 species, orchids are among the most common flowers.
25:00Their beauty, fragrance, and colors compete to attract birds and pollinating insects, particularly butterflies.
25:10Butterflies suck up nectar through their long proboscis, which is sometimes as long as their abdomen.
25:16Rubbing against the stamen, the male part of the flower, the proboscis picks up pollen,
25:22which will then pollinate the pistil of the same flower or another flower of the same species.
25:30Like bee populations, butterfly populations are declining worldwide, and this is a major concern.
25:37The Earth has 2,500 species of flowering plants, and 85% of them depend on insects for pollination.
25:47This pale owl butterfly has nothing to fear.
25:51To discourage predators, its wings are marked with an ocellus, or eye spot, that mimics the eye of a reptile.
25:59The upper side of the wings of this Palletes bluemorpho are bright blue,
26:04but the underside is brown to blend in with the surrounding vegetation when the butterfly is at rest.
26:22If there's one species that doesn't want to blend in with the environment, it's this keel-billed toucan.
26:29Its beak is 15 centimeters long, and it can reach even the most distant fruit.
26:35And it helps with grooving, which sometimes toucans do with obvious pride, especially during the breeding season.
26:56Yellow-throated toucans may have fewer colors, but their bill is just as effective for smoothing their feathers.
27:09In a natural environment teeming with insects and parasites, birds spend much of their time scratching, cleaning, and preening their
27:18plumage.
27:20While some birds' appeal is based on their bright colors, other birds, like the great potu, use camouflage.
27:28The nocturnal great potu sleeps by day, mimicking a tree branch.
27:36Even if it may be hard to sleep through the squawking of the Montezuma oropendala and their acrobatics.
27:53The brown-hooded parrot is much more discreet.
27:58These small parrots live in groups of a dozen or so individuals, but they can also get away from the
28:04others to feast on the best trees.
28:08And this fruit is attracting a lot of interest.
28:18The trees in poorer health are infested by various larvae, mollusks, and insects, to the delight of the cinnamon woodpecker,
28:27who is willing to work to capture them under the bark.
28:42The most insatiable feeders are possibly the black-handed spider monkeys, who vary their diet by moving from tree to
28:51tree.
28:55Up to the age of three months, young monkeys travel only on their mother's back, holding on with their prehensile
29:03tail.
29:04They won't break free until they're a year old, after their mothers have taught them to recognize edible leaves, fruit,
29:11and insects.
29:14Despite their natural curiosity, young black-handed spider monkeys must avoid toxic plants.
29:22Scientists believe that this learning effort, and the memorization it involves, have contributed to developing the intelligence of spider monkeys.
29:30They are actually ranked third for intelligence behind the orangutan and the chimpanzee.
30:01whoopin beautiful-バイズ
30:05The mini snail
30:05For the youngest ones who aren't yet capable of picking fruit on their own,
30:10there is the temptation to steal, despite the likelihood of being caught.
30:30Pinching someone else's food would require both skill and tact.
30:36From there to the hovering illustration cmd咎 под Christmasmd咎...
30:53Did you call it the
31:06Larceny may have ended in failure and in being scolded, but there's nothing more comforting
31:12than mother's milk.
31:20Each female bears just a single baby monkey every two to four years.
31:25The rate of reproduction of spider monkeys is too low to offset the effect of poaching
31:30and deforestation, especially in the countries neighboring Costa Rica.
31:35The black-handed spider monkey is therefore considered an endangered species.
31:45Living at altitudes below 500 meters, and capable of reaching the age of 50, scarlet macaws
31:52are less endangered.
31:53The female can lay two or three eggs a year, providing that she accepts a mate.
31:59Couples spend lots of time bickering, and the sound is deafening for this red-eyed frog,
32:05which only wants to sleep in peace during the day.
32:12During delousing sessions, the slightest mistake in grooming can cause a fight.
32:24Despite the quarreling, this couple will stay together all life long.
32:30The ceremonial smoothing of feathers helps to maintain the flame.
32:36But once again, beware of clumsy beaks.
32:46The red-eyed tree frog is now fully awake, but won't go hunting for insects until after sunset.
32:52It keeps a discreet watch on its surroundings, with semi-transparent eyelids over its big red eyes.
33:04As twilight fades, the calm returns.
33:16Even this family of howler monkeys, high in a tree, are dining in silence.
33:21Better not let the big cats, ocelots, cougars, or jaguars, know where you are before falling asleep.
33:39The night is filled with the sound of insects.
33:46Predators are resting or waiting in ambush.
33:49The most alert creatures are the spiders, particularly tarantulas, on the lookout for prey near the entrance to their burrow.
34:00Tarantulas eat insects, reptiles, and small rodents by injecting digestive enzymes to liquefy their flesh before sucking out the liquid.
34:11Woe to any creatures that vibrates their web.
34:15Leaf-cutter ants, which provide nutrients to the fungi they feed upon, are unlikely to be caught by tarantulas,
34:22because they carefully follow the path of their own pheromones, leading back to the ant hill.
34:31The kinkajou is mainly a fruit-eater, but is ready to use its long tongue to catch ants, or maybe
34:38a tiny frog.
34:41Many nocturnal animals play it safe, by blending into the background.
34:47Whatever happens, this will be a good night for some, while others won't live to see the following day.
34:54The kinkajou is only a few meters above sea level.
35:15Barely a few meters above sea level, coastal plains are crisscrossed by channels and marshes.
35:22There are no roads across this muddy maze, abandoned to tropical humidity, and that's good news for the wildlife here.
35:32At daybreak, this black-crowned night heron stands sentinel over the surroundings.
35:38Better to stand above the water, where an American crocodile is watching and waiting.
35:47Here there are species that cannot coexist with humans, such as Baird's tapper.
35:52This one is resting, unaware of the looming danger.
36:06This is also one of the last sanctuaries for the jaguar.
36:11The big cat, whose territory once spanned both North America and South America, is now confined to a few pockets
36:18of impenetrable jungle.
36:20Sightings are extremely rare. Still, it can sometimes be spotted catching the sun on the banks of a river, always
36:27on the lookout for creatures crossing its territory.
36:31The black vulture and the white-headed Keperson both prefer to get away, more or less discreetly, while the going
36:37is good.
36:43Luckily for them, the jaguar is sated, and only wants to rest in peace and quiet.
36:49Despite weighing seventy kilograms, the jaguar moves in silence, and its spotted coat can quickly vanish in the vegetation.
37:01There are other big cats prowling on the forest floor.
37:06It's much smaller than the jaguar, but the ocelot is also very discreet.
37:11While spending much of its time perched on branches, the ocelot prefers to hunt on land.
37:18It obviously cannot attack a tapper, but takes on all kinds of rodents, small reptiles, and even careless birds.
37:33Snakes often remain motionless to watch their prey, and they move in silence.
37:39This bird snake, a member of the colibrid family, is searching for bird eggs.
37:45But its tongue detects a smell much stronger than any bird.
37:52Some twenty-collared peccaries are moving in the bird snake's direction.
38:01Snakes have poor eyesight, but their forked tongues let them locate the origin of any scent,
38:07using the sense of smell, the same way that we can locate sounds using both ears.
38:18Peccaries are not a threat to the snake unless they sense they are in danger.
38:23The snake, nevertheless, prefers to wait till the peccaries have gone before continuing on its way.
38:37Now that there's no danger of being trampled, the reptiles can come back into the open.
38:42This young, black, spiny-tailed iguana is looking for insects.
38:46Like all iguana species, it will switch to flowers, fruits, and leaves, but only after reaching adulthood.
38:54For the time being, it still needs a high-protein diet.
39:00These sleepy little bats won't be competing with the iguana for flies.
39:05But because insects are scarce, it falls back on some vegetarian fare.
39:12When the iguana reaches adulthood, its skin darkens and it grows dorsal spines.
39:20Green iguanas are the most impressive lizard species in Costa Rica.
39:24They live near rivers and streams.
39:28The male green iguana can easily grow to 1.5 meters in length.
39:33His dragon's head can certainly impress smaller lizards.
39:37Reptiles spend much of their time thermoregulating, that is, adjusting their body heat, by shifting their exposure to the sun.
39:45It's complicated because their scales don't provide much insulation from the heat.
39:51Luckily for them, the absolute stillness of smaller lizards makes them easy prey for herons, especially this boat-billed heron.
40:05This is the common basilisk lizard.
40:07Only the male has the characteristic dorsal crest.
40:11They're famous for their ability to run on water, using their long hind legs and toes.
40:17They stay close to rivers and streams, watching for mangoes to ripen on the trees.
40:36Their tiny teeth can't bite through the skin of the mango, so they feast on over-ripened fruit.
41:03The green iguana has more powerful jaws, so that's less of a problem.
41:08Still there's lots of competition for over-ripe fruit that's bursting out of its skin.
41:24Failure means the iguana has to settle for leaves, which aren't as sweet for the time
41:29being.
41:33Green iguanas may look awkward, but they're good swimmers and excellent climbers.
41:38Their powerful toes and sharp claws grasp branches as they climb for food, cool fresh
41:44air, and peace and quiet high in trees.
41:50But they don't get much of a friendly welcome from the scarlet macaws.
41:59Macaws live in groups without a hierarchy, but they have a pecking order for eating.
42:06The oldest macaws come first and get the best locations using their beak like a third foot.
42:20Only when the older ones fly off can the younger, less experienced macaws move to the same trees
42:27to pick the remaining nuts.
42:39Cracking nuts and removing the contents is a skill that young birds are quick to learn.
42:45Between two morsels, they squawk to let the rest of the group know they're there.
42:51The Central American squirrel monkey seems a bit stressed out by the racket.
42:59This monkey is also looking for fruits, especially to feed the two-month-old youngster.
43:08The squirrel monkey is the smallest of the four species of primates living in Costa Rica, smaller
43:13than the howler monkey, the black-handed spider monkey, and the white-headed capucin.
43:25Brown-throated sloths, on the other hand, hardly move at all, whether alone or carrying their young.
43:34They sleep 13 hours a day, and the first thing they do when they wake up is to take a
43:39rest.
43:40The reason is their extremely slow metabolism.
43:43They take 15 to 20 days to fully digest the leaves they eat.
43:49They have a bowel movement only once a week, and that's the only time they leave the tree to go
43:54to the ground, though no one actually knows why.
44:01In any event, the sloth seems perfectly content with its existence.
44:08There's not much that could keep it from sleeping, certainly not the deep courting song of the male great Curacao,
44:16who's trying to attract a mate.
44:24But the female would have to be ready to listen, unlike this white-lined tanager that's hunting a pretty large
44:30spider.
44:38Here, a male cherry's tanager is preening his feathers, while keeping an eye on his female.
44:45Soon, it will be nesting time for the species, and that means building a cozy nest.
44:55That's also why this pale-billed woodpecker has spent the past few days hollowing out the trunk of a dead
45:02tree.
45:03The pecking seems to have awakened the proboscis bats that were sleeping in a nearby tree.
45:10This bare-throated tiger heron shows that we can't be far from a mangrove estuary, where a singular natural phenomena
45:20occurs.
45:23For several hours, with each rising tide, rivers flow backwards, away from the sea, as the rising tide floods the
45:32river's mouth.
45:33And beyond the beach, we see the rolling waves of the Pacific Ocean.
46:03The shoreline, all along the wild coasts of Costa Rica, is the sea, as the sea, as the sea.
46:07The sea is much like the rest of the country, a meeting place for nature.
46:12Here, volcanic rock plunges into the ocean, and the sun's heat gathers up the water that'll be carried to the
46:18mountain peaks.
46:21This is the intertidal zone, where marine wildlife and terrestrial fauna meet.
46:27Hermit crabs scuttle into new shells, and painted ghost crabs, which burrow underground, are prey to the seabirds overhead.
46:40Shore birds and wading birds feed at the river's mouth.
46:56This little blue heron begins its meal with some freshwater crustaceans, and needs some liquid to help wash down the
47:04crayfish.
47:10A few quick strides bring the herons to saltwater fish.
47:14Fish that can't escape their sharp beaks, even if they swim towards the open sea.
47:24It's here, on the original beaches, that the animal populations from North and South America first met and mingled,
47:33in the great melting pot of Central American wildlife.
47:45This is where the green turtle struggles to lay her eggs in the sand, in order to perpetuate the species.
47:55These shores are sanctuaries, where the green turtle hatchlings scramble into the ocean to face their destiny.
48:06These are the beaches where other animals will nest in the sand, or dig their burrows, and see the sunset
48:14over the Pacific Ocean,
48:15where we can hope that nature will be preserved today, and flourish tomorrow.
48:35We are now living in the sand, as it's darkness in the sea, but she knows that you can feel
48:41it.
48:41You will love the sea that she's going to wear the sea that you can wear the sea.
48:41Well, you will love the sea, and die with the sea.
48:52And all these and the sea, and the sea, and the sea.
48:53You
