Under the stars, the snowfields are not dark.

Snowflakes are crystalline structures, and the snow on the ground is like a mirror that reflects the light around them

Under the starlight, each of the snow-capped mountains glows with a surging dark light, and occasionally a huge figure can be spotted running on it, which is a polar bear that comes out to forage at night.

From October to autumn, polar bears need to forage heavily to survive the winter, which is also when they are at their most active.

The surging green glow of the Doomsday Seed Vault in the dark night,

The engine let out a low roar, the heat from the fuel combustion quickly diffused throughout the off-road body, the prisms on the exhaust pipes slowly melted, and clear water droplets fell and froze again on the ground.

As if hearing the roar of a car, the polar bear, which had been running on the snowfield, suddenly stopped its movements and turned around and approached Bi Fang's side.

Seeing this, Bi Fang subconsciously reached out and touched the hunting knife on the side of his thigh.

The bear killed too much, and when he saw them approaching, he subconsciously wanted to draw his knife.

“nonono！” Barrett hastened to explain.

"Don't be nervous, it's a normal reaction."

Bi Fang was stunned: "Normal reaction? ”

That's normal.

Bi Fang saw the polar bear go from jogging to running wildly, with hair flying on its body, which was obviously a sign of extreme excitement.

Is this called normal?

So far, the most common beast that Bi Fang has dealt with is the bear, although the polar bear has never faced each other, but as a unified subfamily, there is not much difference between the two, especially the brown bear and the polar bear, the two have been separated after geographical isolation for less than 600,000 years, and there is no reproductive isolation.

They all have an unusually well-developed acromion, which is a structural feature of the attachment of shoulder muscles, which can be very powerful to drive the forepaws to swing.

Polar bears have claws of more than 5 centimeters, which are shorter than brown bears and slightly longer than black bears, but they are sharper.

While brown and black bears have blunt claws, polar bears have extremely sharp claws, which is an adaptation to walking in snow and ice.

Powerful and powerful, coupled with a sharp effect, polar bears can easily tear through armor plates more than 5mm thick, which means that the two people in the off-road vehicle at this moment are not safe, and it can even be said to be very dangerous!

Bi Fang could see that Barrett himself was also very often, and the little thumb holding the steering wheel trembled slightly.

But since Barrett said so, Bi Fang did not take any further action.

Compared to his own traveler, Barrett should be more familiar with the aborigines here.

Barrett took a few deep breaths, lowered the seat, climbed into the back seat, pressed the switch on his shoulder, pulled the back of the chair, and dragged out a sizable object wrapped in butter paper.

Barrett slowly unwrapped the oiled paper.

A rich smell of grease overflows.

This is......

The butter paper was wrapped so tightly that Bi Fang didn't smell anything unusual when he got into the car.

Barrett cut it with a knife, and everyone saw that it was actually meat!

It's pork belly.

Bi Fang judged the type of meat based on the smell.

There are quite a few in this bag, at least the amount of several pigs, all of which are selected from the fattest pork belly, which is usually leftovers that no one eats, and at first glance, there is not even red lean meat, it is all fat.

Although not much is eaten, there is nothing better for polar bears than to be full of fat, and only fat can keep them through the polar night.

Carrying a heavy bag of butter, Barrett quickly opened the car door, lifted his legs, lifted the fat from his seat, and then picked up the yellow paper, quickly closed the door, returned to his original position and left with one foot on the accelerator.

The whole process was very quick, and it looks like it has been done more than once.

"Phew, I'm so nervous every time I do this kind of thing, this is the fourth time, but my palms still sweat." Barrett let out a long sigh of relief, as if he had accomplished some daunting task.

Well, feeding polar bears in the wild is a daunting task.

After all, no one can guarantee that the last thing a polar bear will eat in its mouth is a sheep.

"Every time we come over, we feed the polar bears some food so that they can be safe." Driving the car, Barrett explained.

Enwei is both powerful, holding a rifle in his hand is Wei, and feeding regularly is en.

As the glaciers melt, fewer and fewer polar bears can catch seals, and a significant number of polar bears do not survive every year.

According to ecological calculations, polar bears may become extinct by 2100.

"We don't overfeed them every time, we usually do it once they come to make sure they don't hit us with excessive hunger."

There has always been a law in nature that is survival of the fittest, and most polar bears are still able to catch enough food to survive their difficult periods.

Only a small percentage of frail polar bears struggle to survive due to changes in the environment. If humans keep feeding them food, they will lose their predatory nature.

As a result, Barrett and others have maintained a fragile balance with polar bears.

Overall, the journey was an eye-opener for the audience.

There is a magical sense of seeing future technology in the real world, and it is also the first time that human beings really have practical plans for the future.

Many people can't help but think of what Bi Fang said a long time ago.

The history of life is a story of mass elimination, followed by the differentiation of a few survivors.

The Earth has witnessed five mass extinction events, and in each case, 70%-85% of species will be extinct. In the Permian, more than 95% of the animals withdrew and never returned.

For nearly 3.5 billion years, mankind has successfully survived time and time again.

In the next hundreds, thousands, or even hundreds of thousands of years, will you swim in the sea of stars, or will you become part of a fossil?

All the way back to the city, Bi Fang said goodbye to Barrett, also turned off the live broadcast, and walked slowly on the streets of the city alone.

Quite deserted......

After all, it's a place where there are more polar bears than people.

There were no vendors, let alone stalls, just orange street lamps, and the occasional street lamp passing by.

The background color is black, and a white polar bear is depicted on it, and the warning sign with a red outline also informs passers-by of possible dangers outside.

The vast majority of polar bear attacks on humans occur at night.

In fact, it's only six o'clock in the afternoon, and it's still dusk in any low-latitude city, but here, the night is as deep as midnight.

Back at the accommodation, Bi Fang had nothing to do, and was about to take out his mobile phone to play a few games and go to bed after suddenly the phone rang, and the front desk of the hotel informed him that someone was looking for him downstairs.

Someone looking for me?

Bi Fang was stunned, although he has many friends, he hasn't traveled to the most remote city in the world, right?

With curiosity, Bi Fang came downstairs, but what he saw was a strange man he didn't know at all.
