Twenty years ago, no biologist on an expedition to the Arctic would have described a polar bear as skinny or weak.

The general impression is that the polar bear will always be the strong Arctic hegemon.

They have no natural predators in this land, and they can run on the ice fields without worry, and their huge bodies will even tremble on the earth.

They swim in the ocean, and their sturdy forelimbs give them web-like functions, allowing them to move freely through the water.

Some polar bears are even able to migrate between hundreds of kilometers of land across the ocean, spending most of their lives floating on sea ice and only landing on land during the breeding season.

Sea ice also has the benefit of providing a steady source of food for polar bears – seals.

When seals ventilate and rest on the sea ice, they are likely to be a meal for polar bears, who occasionally eat some whale carcasses.

Even if polar bears are not so lucky and don't catch seals, the layer of fat they store under the skin can provide them with energy for a certain amount of time.

"This layer of fat makes them look strong." Bi Fang said.

Polar bears are completely different from brown bears, with a very thick layer of fat and a larger body frame that is used to hold and support everything in size, so the head-to-body proportions are completely different.

The difference between the two is visible to the naked eye.

Polar bears have relatively small heads, slender necks, and hind limbs that are slightly longer than their forelimbs, and their bodies are tilted forward. Brown bears, on the other hand, have a rounder head, a short and thick neck, and no significant difference in the length of their limbs, and their bodies are parallel to the ground.

Even non-professionals can easily distinguish between two species, so how can a brown bear not be recognized by a professional staff member of an animal protection organization because it wears a white vest?

The story of the so-called albino brown bear "Qiao Yin" on the Internet being mistaken for a polar bear and being sent to the North Pole twice is nothing more than a false concodiation.

Although none of the albino brown bears named Qiao Yin have made it to the Arctic twice, many have actually lost their homes and have been forced inland in search of food.

It was from the beginning of this century that everything began to change.

When exploring the Arctic, one can occasionally spot a skeletonized polar bear that looks like a walking skeleton bear.

If these polar bears can no longer find food, they will inevitably starve to death, but their weak bodies can no longer withstand the intensity of hunting, and their death is doomed.

As global warming accelerates, sea ice is becoming shorter-lived, making it difficult for polar bears to hunt, potentially facing increasingly stressful living conditions and higher mortality rates, and having to travel farther afield to catch prey in order to get enough food.

Polar bears left the North Pole.

Polar bears have struggled with a number of headwinds over the years, and the disappearing polar bears have also told humans that they have lost the battle without natural predators.

"Polar bears we've been wept from the sea ice and lost seals, a vital food, but in the southeast of Greenland, we're finding an isolated population of polar bears that are genetically different."

"Unlike other polar bears that depend on sea ice for their survival, these bears hunt year-round on the water near ocean glaciers, where sea ice conditions are close to what we predict for the Arctic region at the end of the 21st century."

From the past to the present and the future, Bi Fang explains why the polar bears in Greenland seem to be living well.

"The polar bears here will probably be the only ones that will survive in the future, and they will be more adaptable."

Bi Fang stood on top of the ice field, looking at the giant bear staring at him in the distance, and smiled.

During the days galloping on the snowfield, Bi Fang saw a lot of creatures, which brought him a great sense of novelty, and recently he had his eyes on an arctic female bear, and every day he took her child to look for food on the ice field, watching from a distance, very interesting.

The giant Arctic mother bear swayed forward with her huge body, and the young bear cub followed behind, often attracted by other things around her, until she came back to her senses and found that her mother had gone away.

The baby polar bear scrambled to its feet, ran and jumped to keep up, and then attracted attention by the ice or stones on the side of the road, and so on.

"For many endangered animals, they only have one chance, and the shrinking base gives them no chance of trial and error. They are not like the hares of Australia, even if a special racial virus is developed, there is a large enough base to ensure that individuals with antibodies can still reproduce stably. ”

"Not to mention that many animals, plants and careful creatures cannot be effectively counted at all, and most of the time it is not even clear whether they are extinct or not."

"The risk of extinction of many species may be much more serious than we thought, such as the north-stomach frog in Australia, which took less than a year from discovery to complete extinction."

[Whoever kills is looking for whom, the money was earned by others, and now others have to bear the consequences, even if it becomes extinct after 10,000 steps, it will not affect me, a person who even has to pay money to enter the zoo]

[The misery of life makes people boring, alas:-(]

[Human development is to remove the wooden planks in the wooden house in winter to keep warm, but a cement house is still being built next to it. If the wooden houses are completely destroyed before the new houses are built, the extinction of mankind will not be far away. But if you don't remove the plank, some people won't see the sun the next day. 】

"Many people may not understand the impact of the extinction of such small things, such as the Pinta Island tortoise, or the turtle, which has no impact on our lives at all, and the protection of animals is more out of compassion."

"But I think species conservation is like playing stacking music, this is a kind of building block game, I don't know if you have ever played it, that is, a large number of square wooden blocks are neatly stacked into a large cuboid, and individual wooden blocks are constantly extracted from it until the cuboid collapses after who pulls it out."

Water friends have realized that many people may not have played this kind of game, but they have also heard of it, and it is used as a metaphor at the moment, vivid and vivid.

"Species conservation is all about minimizing the number of bricks that are being pulled out and protecting the edifice of the biosphere from collapsing."

Bi Fang smiled: "I've said similar things many times, no matter how much it seems to be preachy, it's just that this time the survival is coming to an end, and it seems that I can't sublimate the theme without something, which reminds me of the ending that I had to have when writing essays before." ”

"So let's start having fun."

The biosphere has evolved over hundreds of millions of years to become what it is today, during which countless species have appeared and disappeared, and have undergone various reshuffles and restarts, and humans have been the biggest beneficiaries of this round.

The extinction of one or two species certainly does not destroy the entire body size, but their extinction warns of great changes in the environment, and there is no way for humans to repair the damage to the biosphere out of thin air, so it is a good thing to avoid its further deterioration.

Bi Fang believes that in the future, mankind will definitely explore a way of development that is more beneficial to itself and the biosphere.

As soon as the words were finished, the young polar bear accidentally tripped and fell to the ground because it was chasing too fast, and its bones rolled several times, and its fluffy fur was covered with dry snow.

The mother polar bear finally noticed her mischievous child, turned around and bit the back of the bear's neck, shook it a few times, and shook off the snow to help it get back on its feet.

One bear, one small and one bear, continued to walk into the distance.

The audience who saw the same scene laughed even more, and many female fans felt that their hearts were about to melt, and the bear was so cute.

And more, they are still discussing what Bi Fang just said.

[Not long ago, the Yangtze River white sturgeon was also completely extinct]

[I first met the Yangtze white sturgeon in the text called "Living Fossils", it was still an endangered species at that time, and now it is gone, which is a pity]

Each species has its own unique advantages, for example, artemisinin is extracted from Artemisia annua, and each species has the potential to bring great benefits to humans. Human beings protect animals not only for that kindness and morality, but also to protect themselves and leave a way out for themselves in the uncertain crisis of the future. 】

[For human beings, it is the evil consequence of destroying the environment, but human beings will not become sinful people.] Natural selection, survival of the fittest. Human beings will destroy the environment and gradually stop being "fittest", so they will protect nature. 】

......

Mid-January.

Bi Fang has been living in the Arctic for more than 90 days, and there is less than a week left before the final end.

Three months of survival in the wilderness was the longest task Bi Fang had ever done, and his image was completely different from when he first came here.

Hair that has not been taken care of for a long time does not look oily because it is washed frequently, but it still looks a little sloppy because it is too long.

This is unavoidable, Bi Fang can simply shave some of it, but in the cold Arctic, this is completely unnecessary, on the contrary, thick hair can also be kept warm to a certain extent.

The overall weight has also been reduced to a certain extent, although there has been hunting during the period, but it is still inevitable that it has declined, but the decline is not much, it is still maintained at about 80 kilograms, probably the state before fattening.

After coming and going, nothing has changed, and everyone is happy.

This also further proves that Bi Fang's survivability is indeed at the top of the human race.

In the same show in the previous life, the environment was not even as bad as Bi Fang, and in the case of being in the forest, almost all the contestants would lose weight significantly, and some even lost dozens of pounds directly, which was terrifying.

But this only shows that the contestants are not capable, after all, if they had to lose weight to survive in the Arctic for 100 days, then the Inuit would have been extinct long ago.

"Sun and Moon"

Bi Fang was only a little uncomfortable in the early stage, and quickly controlled his survival state in the later stage and entered a stable living environment.

From one environment to another, and to live like an indigenous, or even better, all this shows Bi Fang's ability.

He has the ability to survive in one of the harshest environments on Earth for a long time, and even has the power to feed six large dogs!

Malamutes can eat more than people, in other words, Bi Fang can even feed ten people by himself!

This horrific conclusion made everyone realize something.

If he really came to the apocalyptic environment, as long as it wasn't for a meteorite hitting the earth and destroying the entire planet at once, this guy would definitely be the last person to live, and he could even bring others to live with him.

Today, Bi Fang went out as usual, he put on a snow-white scarf, beckoned six sled dogs, gently closed the wooden door, and plugged in the latch.

The deserted Arctic didn't need anything like this, until after the Arctic wolves attacked once, Bi Fang decided it was necessary to install one to prevent the sled dogs from suddenly running out.

Plugging in the wooden bolt, the cabin trembled slightly, a few smoked rabbits hanging on the edge of the wooden house shook a few times, the snow on the edge of the roof fell, there was a snowstorm some time ago, the wooden roof was completely covered with snowflakes, but the angle of inclination was too large, and the snow was not too thick.

Seeing the swaying smoked rabbit meat, which could make the sled dogs on the side salivate, Bi Fang looked up and patted his head.

"I forgot to put them in."

If you don't bring them back to the house, you might be eaten by something.

After putting away the smoked rabbit meat on the edge and putting it in the house, Bi Fang set off again in a sleigh, traveling on the vast ice field to witness more scenery.

The temperature is still very low, only about minus 30 degrees, but compared to minus 60 degrees in the snowstorm some time ago, it can already be called "warm".

It was a time of real horror, and the temperature was minus 60 degrees Celsius, and Bi Fang felt as if even his soul was about to freeze.

The surrounding environment is still the same gray and white, but Bi Fang does not feel lonely and monotonous.

Even on the eternal ice sheets, new life and new things appear every day.

Every morning is different.

Every life has a new story.

The wind will bring the seeds of the story, and time will make it germinate.

Bi Fang enjoys this kind of life and does not feel difficult.

Of course, such a life guarantee comes from Bi Fang's strong ability to survive, if you change people, it is already very difficult to survive, let alone experience the beauty.

Normal people come to the Arctic to survive, and they can feel the cruelty of only nature and the harshness of the environment, so that they cry in despair.

"It stands to reason that the sun should rise in these two days, I don't know if it can be met."

In mid-January, it's already the time when the polar night is about to disappear.

Bi Fang, who was driving a dog sled, said to himself that he had been wandering around the ice field for the past two days, where there were no hills or trees, and there was no end as far as the eye could see, so that he could see the rising sun as soon as possible.

From the polar night to the polar day, the experience is absolutely breathtaking.
