Above the desert, towels under felt hats flutter in the wind.

Bi Fang subconsciously opened his mouth, trying to feel a trace of coolness, but the wind blowing over was like a hot flame, except for pouring into the throat, burning the tongue, and scalding out a wisp of green smoke, there was no superfluous effect.

After more than a week of travel, as Bifang went deeper, the nearby sand dunes became higher and higher, and there were fewer and fewer rocks.

Burkina Faso has long been in the background, and at this time the area has reached the hinterland of Mali, and as far as the eye can see, there are towering golden low mountains everywhere, stretching continuously to form thousands of golden waves, which are quite gorgeous in the sunlight, like a golden sea of infinite light.

"Now it's not just food, it's also starting to strain water."

The drone camera is deflected to the side of the camel, on which are hung two rattlesnakes with no snake heads, the only remaining watermelon, a few palm berries, and finally a jug of water in Bi Fang's backpack.

That's all the stuff for one person and one camel now.

[Fang Shen is wrong, in fact, there is still a large half ton of reserve materials]

[You can be a person]

[Alpha did something wrong, you have to do this to it]

Alpha.

Bi Fang gave the male camel its name.

It didn't have any special meaning, it was just easier to call, and in the past two days the camel seemed to understand that the title was its name, and began to respond.

And the relationship between the two has gone further, and at night they do not deliberately lead the camel to a distance of three meters and tie it, but directly with them.

On the surface, Alpha is no different from ordinary camels, but there are some overly intimate actions that Bi Fang still won't do, such as standing behind him for a long time, or feeding at close range.

Animals in nature are strange, and nature has endowed animals with ingenious relationships, some animals and people are kind, some people regard man-made disasters, and some animals and humans have not seen for thousands of years, but they can have natural emotions.

The sun was blazing, and the time came to noon, Bi Fang stroked Alpha's neck and found a place to rest, avoiding the hottest time of the day.

Leaning in the shadow, Alpha tossed the sand with his hooves and sat down on his knees in a comfortable position on his own.

Bi Fang took some fruit from it, as well as a rattlesnake, sliced the pre-smoked snake meat with a dagger, and stuffed it into his mouth to replenish his strength.

I have to say that the emergence of alpha has brought great help to Bi Fang.

Throughout the journey, Bi Fang saved a lot of energy and time, and did not have to interrupt the journey frequently for water and food.

It is very difficult to walk from Burkina Faso to the heart of Mali on a normal route, and it is very difficult to walk without twenty days on both feet, and it takes time to hunt and find water and food, but with the help of camels, this time can be shortened to ten days, which is more than twice as fast.

Catch two rattlesnakes today, catch a scorpion tomorrow, and the day after tomorrow you may encounter a small lizard or jerboa.

The only regret is that the jerboa is an endangered species and cannot be eaten, so Bi Fang gave it a brain meltdown, and let the big-eared mouse let it go after knowing that people are sinister.

These animals are not large in size and cannot be fully fed, but this kind of thing that can be easily caught on the way is indeed very convenient and simple, and it accelerates the whole crossing process in disguise.

"Taming and domestication are not the same, and taming domesticated animals is the third type."

"'Taming' is the taming of an individual animal, i.e. harmless to humans. Usually it is used to imply some kind of friendly relationship, culminating in the idea that for some species it is okay to be with people without wanting to kill them. ”

"A species may be more or less adapted to domestication, but ultimately it is an individual process."

"Domestication, on the other hand, means that humans have changed a species to make it easier for it to coexist with humans. The members of this species are now different from any of the original species they came from, and their instincts have been altered so that for them, being friendly with humans makes their attitude towards humans more natural. ”

"Jared Diamond, in his book Guns, Bacteria and Steel, discusses what makes a species domesticated or not domesticated, including the specific case of horses and zebras."

He pointed out that 14 large animals were completely domesticated by humans: sheep, goats, cows, pigs, horses, Arabian camels, Bactrian camels, camels and alpacas, donkeys, reindeer, buffalo, yaks, Balinese cattle and Mitan. Many of these species are related. And he claims that in order for a species to be domesticated, it must possess certain characteristics. ”

"It has to be an omnivore or herbivore, it has to grow fast, it breeds well in captivity, it has a proper temperament, and some animals are actually very nasty or completely hostile to humans, like zebras, because they have a short temperament, they bite a lot, and then they can accept incarceration, and finally there is a social structure that allows them to accept subordinate roles, or hierarchy."

"This is consistent with a currently popular theory that we domesticate animals by playing a role in their natural hierarchy. In other words, animals allow us to play an existing role that their own humans would normally assum. ”

"For example, the owner of a dog is seen as part of a pack, like the head wolf in a pack."

"It has also been suggested that many of the animals we domesticate evolved into a state of extended childhood, in which they respond to us at an early age, and in their species, adult animals do too."

Although a zebra resembles a horse, it is almost impossible to tame it.

Back when the Boers settled in South Africa, they tried to tame zebras, but the results were not as good as they could be.

Any additional pressure on the back of these animals can cause panic, and it will take generations of domesticated zebras to tame them, and more tame variants, like wheat, may take hundreds or more.

Horses seem to have a different genetic pathway, which led to their domestication.

They find themselves living in northern latitudes and have far fewer predators other than humans.

As a result of the Ice Age and subsequent human migration to North America, they would be endangered due to overhunting by their Indian ancestors, so the refuge moved to the northern latitudes of Asia, where horses were first preserved as a food resource and then domesticated by humans for use.

Horses have developed a bond with species that have almost made them completely extinct.

"Today, it's the opposite, because there are more than 60 million horses and less than 800,000 zebras in the world."

"Nature is so wonderful."

After listening to Fang's talk about the difference between zebras and horses, many viewers had many ups and downs of thought.

【Cowhide】

[Those who follow me prosper, and those who oppose me die]

【Wonderful Nature】

[When can you domesticate the tiger, and when the time comes, the big cat]

[Brother, is the Siberian tiger masturbating, this is strong]

Bi Fang chewed on the flaky snake meat, like gnawing on a piece of leash, hard and old, difficult to chew, swallowing into the smoking throat as if swallowing a piece of prickly fur.

"As for the idea of taming sharks, snakes and lizards of all kinds, it is even more impossible, the reality is that most species on Earth are impossible to tame, and even those animals that have been tamed to a certain extent cannot live very close to humans without exhibiting behaviors that endanger animals and human hosts."

"Many people like to raise some curious creatures, I have no objection, but the premise is to take good care of them, don't let them escape, let alone release them into the environment, causing species invasion, even if you really don't like it, it's best to solve it yourself."

[In other words, will there be more and more animals raised by Fang God in the future]

[There is one thing to say, last time it was six dogs, and now it is a camel, I think Lao Fang has the potential to open a zoo]

[Expect the day when the wilderness zoo opens]

[Why doesn't Lao Fang take the dogs to the club to yo-yo, let them run happily, how happy]

"I'll think about it."

Bi Fang smiled and did not refuse the fans' requests on the spot.

At four o'clock, the sun was slightly slanting to the west, and the sunlight in the air was no longer as scorching as at noon, Bi Fang grabbed the reins of Alpha and got up to continue walking.

"There are many stories about this desert, it is said that a caravan once passed through the Sahara Desert and ended up falling on the desert due to lack of water, but in fact there are wells nearly 100 meters away, and maybe they died from their own hopeless hearts."

"Water is really a priority in desert survival, and if there is water, then rationing should be limited."

"It depends on having access to the necessary water resources and at the same time protecting against the sun and minimizing water loss. Allow for a slight imbalance. For every two liters of water loss, at least one and a half liters should be supplemented, which is a ratio of 4:3. ”

"It's important to hydrate your body after sweating so that the damage is minimized and precious water resources are not wasted."

"Lack of fluid does not reduce the amount of sweating, which is one of the cooling mechanisms in the body, not to expel water. If you drink too much water at one time, more than your body needs, you will be excreted immediately, which is not beneficial, and you can even get water poisoning. ”

[Water poisoning, I don't say who it is]

【Hahaha】

[It's a little interesting]

"If you are blocked by a vehicle breaking down on your planned journey through the desert, you may and should have identified known oases, qanats or water holes along the way."

"The qanats can be very deep and require buckets and ropes to lift the water. The water holes at the bottom of the dry riverbed are often seasonal, and there are usually slate or branches covered by predecessors, and you can spot them according to this. ”

"If you are far from the known water holes, you may find water by digging down at the lowest point outside the bend of a dry stream, or at the lowest point between the dunes."

"Of course, in the desert, it's worth trying to follow the local wildlife for water, and there is a famous saying among the inhabitants of desert areas: 'It's wiser to take the path that already exists than to forge a new one.'"

[Strange quotes added]

[This is used in the composition]

[Last time I used Fang Shen in my writing, hahahahaha]

[I rub, this can also be used?] 】

[What brave or something, anyway, just put it up, make it hard, hard it's hard, don't do it, it's safe, although it's uncomfortable, but there is a guarantee]

[Why do I feel that the more I hear this, the stranger it becomes]

"People and animals usually follow the same path, and these roads tend to twist and turn and stretch throughout the land."

"If you come across a road in the desert that is often walked by people or animals, be sure to follow it."

"Don't take a straight line to avoid those turns. This is because people or animals often walk this path with the least obstacles, and often from one shady place to another, from one water source to another. ”

"It's a great trick in many situations, like when I followed a white-limbed bison in the rainforest to find a salt mine, but it can be dangerous, but it's important to remember that some desert animals don't drink water, but get enough water from their food."

"You need to have a lot of experience and the ability to discern animals."

"Always keep in mind that you should save as much energy and water as possible, make the most of your time and space, don't work in hot weather, sweat will take away more body fluids, and you may not be able to find water, you must balance the loss of body fluids with the possible gains."

"Depending on the environment, you can even take advantage of the water provided by cacti and various roots, and you can also take advantage of the huge temperature difference between day and night in the desert to condense water vapor for water."

[Oh, speaking of which, I don't seem to have seen a cactus or something]

[Hey, as soon as you say that, I also remember, it seems that the old man has been walking for so long, and he has never encountered a cactus, there are so many plants before, I have never seen it]

"Because there are no cacti in the Sahara, no, you can't say that there are none, it can only be said that there are very few, after all, globalization, it is normal for species to invade or something."

Bi Fang's gaze swept to the vast desert around him and explained.

This immediately surprised everyone, because in their impression, the desert and the cactus are an inseparable pair of CPs!

"This is a common misconception of normal people, cacti are American plants, and not all deserts can survive."

"Cactus belongs to a typical CAM plant, that is, a plant with sedum acid metabolism pathway, mostly a slurry plant, simply understood as succulent, the leaves degenerate into needles, and the daytime pores are closed, reducing transpiration; The stems are thick and juicy, with well-developed parenchyma cells that store abundant water; The epidermis of the stem has a thick, hard wax that acts as a protective layer......"

"Because of these abilities, it is resistant to hot and arid environments, and in addition, the cactus has a large root system, which can absorb the precipitation of the rainy season and store it in the body for use in the dry season, so that it will not live on the scorching sand and stone and dry out."

"The southern part of Modonge and Chouguo belongs to the savannah climate, there are obvious dry and wet seasons, the wet season is shorter, and the cactus absorbs a lot of water in the wet season to preserve water to ensure water consumption in the dry season."

"But!" Bi Fang paused, attracting everyone's attention, "It is not resistant to cold, and it is difficult to survive below zero." ”

"For example, the Taklama wet, although the summer is hot and dry, but the winter is cold, so it cannot reach the temperature conditions for cacti to survive in the wild, so there is no growth in the wild."

"The Arabian Peninsula in the Middle East and even the entire Sahara Desert is a typical tropical desert climate, where it is hot all year round, precipitation is scarce, and the water conditions are too poor to support the cactus' water storage requirements, and the night temperature is usually below zero, so there is no cactus distribution."

"But further north, offshore locations, such as Morocco, where there are more cacti, and even cactus forests, are still very shocking, and you can go and see them when you have time."

[Okay, I'll go when I'm free (dog head]

[Shocked me for a whole year, I always thought that cacti and desert were normal configurations, but not all of them turned out]

[Indeed, this is the first time I've heard of such a thing......]

[A little hanging]

[Fang Shen knows a lot]

[In the future, if I talk about the strong vitality of cacti, can I refute it like this? 】

[Actually, it doesn't work, because it's still very strong (funny)]

The rainbow fart blew again in the live broadcast room, but Bi Fang grabbed the reins at this time and sniffed gently.

Just when everyone thought there was something abnormal, Bi Fang suddenly smiled.

"A sandstorm is coming."
