Chapter 809 sandstorm

Above the desert, the towel under the felt hat fluttered in the wind.

Bi Fang opened his mouth subconsciously, trying to feel a hint of coolness, but the wind blowing was like a scalding hot flame. Except for pouring into the throat, burning the tongue, and burning a wisp of blue smoke, it had no superfluous effect. .

After more than a week’s trip, as Bi Fang went deeper, the nearby sand dunes became higher and higher, and the rocks became less and less.

Burkina Faso has long since become the background behind it. At this time, the range has reached the hinterland of Mali. As far as the eye can see, there are towering golden low mountains everywhere. It is gorgeous, like a golden ocean shimmering with infinite light.

“It’s not just food, but water resources are starting to strain.”

The drone camera is deflected to the camel’s side, with two rattlesnakes without their heads hanging on them, only a watermelon and some doom palm fruit, and finally a pot of water in Bifang’s backpack.

This is all the materials for one person and one camel now.

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

【You can be yourself】

[What did Alpha do wrong, you have to treat it like this]

alpha.

The name Bi Fang gave to the male camel.

It doesn’t have any special meaning, it’s just a little more convenient to call. The camel seems to understand that this title is its name in the past two days, and began to respond.

And the relationship between the two went further. At night, he did not deliberately lead the camel to three meters away to tie it, but took it directly by his side.

On the bright side, Alpha is no different from an ordinary camel, but Bi Fang still won’t do some overly intimate actions, such as standing behind it for a long time, or feeding it at close range.

There are all kinds of strange animals in nature, and nature has endowed them with ingenious relationships. Some animals are kind to humans, while others regard humans as natural disasters. Some animals and humans have not seen each other for thousands of years, but they can have natural emotions.

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

Relying on the shadow, Alpha threw the sand with his hooves, and chose a comfortable position to kneel and sit down by himself.

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

It has to be said that the appearance of Alpha has brought great help to Bi Fang.

During the whole journey, Bi Fang saved a lot of physical strength 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 hinterland of Mali, and it is even on the route to be walked. It is very difficult to live without feet for 20 days. In the middle, it takes time to hunt and find water and food. But with the help of camels, this time can be shortened to less than ten days, more than double the speed.

Catch two rattlesnakes today, a handful of scorpions tomorrow, and a small lizard or jerboa the day after tomorrow.

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

These animals are not big enough to eat enough, but this kind of thing that can be easily caught on the road is indeed very convenient and simple, and it accelerates the entire crossing process in disguise.

“Tame and domestication are not the same, and domestication of animals is the third.”

“‘Tame’ is the tameness of an individual animal, i.e. harmless to people. Often it is used to imply some kind of friendly relationship, culminating in the idea that for some species ‘can be with people and not want to kill them’ .”

“A species may adapt more or less to domestication, but ultimately it’s an individual process.”

“And domestication means that humans have changed a species to make it easier to coexist with humans. The members of this species are now different from any original species they came from, their instincts have been altered so that for them, it is not the same as humans. Friendly, making them more natural with humans.”

“In Guns, Germs, and Steel, Jared Diamond discusses what makes or does not domesticate a species, including the specific case of horses and zebras.”

“He points out that humans have completely domesticated 14 large animals: sheep, goats, cattle, pigs, horses, Arabian camels, bactrian camels, camels and alpacas, donkeys, reindeer, buffaloes, yaks, Balinese cattle and mitans. These Many species are related. And he claims that a species must have certain characteristics in order to be domesticated.”

“It has to be an omnivore or herbivore, grow fast, breed well in captivity, have a proper temperament, some animals are actually quite annoying or outright hostile to humans, like zebras, because they have a hot temper and often bite people , then being incarcerated, and finally having a social structure, or hierarchy, that allows them to accept subordinate roles.”

“This is consistent with a currently prevailing theory that we domesticate animals by playing a role in their natural hierarchy. In other words, animals let us play an existing role that their own humans would normally assume.”

“For example, the owner of a dog is seen as a member of the pack, like the alpha wolf in a pack of wolves.”

“It has also been suggested that many of the animals we domesticate evolved into an extended childhood state in which they respond to us at an early age and, in their species, adults respond as well.”

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

As early as when the Boers settled in South Africa, they tried to tame zebras, but the results were less than satisfactory.

These animals panic at any extra back pressure, and to tame it will take generations of domesticated zebras before a more tame variant, like wheat, may take hundreds of years or more.

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

They found themselves living in northern latitudes with far fewer predators other than humans.

Due to the Ice Age and subsequent human migration to North America, which would have been endangered by overhunting by their Indian ancestors, refuges moved to the northern latitudes of Asia, where horses were first preserved as a food resource and then domesticated by humans for for use.

Horses are linked to a species that nearly wiped them out.

“Today, the opposite is true, as the global horse population exceeds 60 million and the zebra population is less than 800,000.”

“Nature is so wonderful.”

After listening to Fang Fang’s description of the difference between zebras and horses, many viewers had many ups and downs.

【Cowhide】

[Those who obey me will prosper, those who go against me will perish, right?]

【Wonderful nature】

【When can you tame tigers, then slap big cats】

[Brother, is the Siberian tiger licking, this is powerful]

Bi Fang chewed the flaky snake meat as if he was gnawing on a leather belt. It was hard and old, making it difficult to chew, swallowing it into his smoking throat as if he had swallowed a piece of thorn fur.

“As for the idea of ​​taming sharks, snakes and various lizards, the reality is that most species on Earth are impossible to tame, and even those that are tamed to a certain degree cannot live in close proximity to humans without exhibit behaviors that endanger animal and human hosts.”

“Many people like to keep some curious creatures. I don’t object, but the premise is to take good care of them, don’t let them escape, and don’t release them into the environment, causing species invasion, even if you really don’t like them, it’s best It was solved by hand.”

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

[One thing to say, last time there were six dogs, and now it’s a camel. I think Lao Fang has the potential to open a zoo]

【Looking forward to the day when the Wilderness Zoo opens its doors】

[Why didn’t Lao Fang bring the dog eggs to the club for a yo-yo, let them run happily, how happy?]

“I will think about it.”

Bi Fang smiled and did not reject the fans’ requests on the spot.

At four o’clock, the sun slanted slightly to the west, and the sunlight in the air was no longer as vicious as it was in the middle of noon. Bi Fang took Alpha’s reins and got up and continued on his way.

“There are many stories in this desert. It is said that caravans once passed through the Sahara Desert and finally fell in this desert due to lack of water sources, but in fact there are wells nearly 100 meters away, maybe they died of their own. A hopeless heart.”

“Water resources are indeed a top priority in desert survival. If there is water, the ration should be limited.”

“It depends on the availability of the necessary water resources, and at the same time protecting against the scorching sun to minimize water loss. A slight imbalance is allowed. For every two liters lost, at least one and a half liters should be added, which is a 4:3 ratio. Proportion.”

“Being hydrated after sweating keeps the damage to a minimum and doesn’t waste precious water resources.”

“Lack of body fluid will not reduce the amount of sweat. Sweat is one of the mechanisms of cooling the body, and the purpose is not to expel water. If you drink too much water at one time, more than the body needs, it will be excreted immediately, which is useless, and even water is lost. poisoning.”

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

【Hahaha】

【interesting】

“If your planned drive through the desert is blocked by a breakdown of your vehicle, you may and should have identified known oases, karez or waterholes along the way in your plan.”

“Kare wells can be very deep and require buckets and ropes to lift water. Water holes at the bottom of dry riverbeds are often seasonal, usually with slate or branches covered by predecessors, and you can spot them based on that.”

“If you’re far from known water holes, you might find water at the lowest point outside a turn in a dry stream, or in the lowest point between sand dunes.”

“Of course, in the desert, tracking local wildlife for water is worth a try, and there is a famous saying among the inhabitants of desert areas: ‘It is wiser to take an existing path than to blaze a new path.'”

【Strange quotes added】

[This is used in the composition]

[The last time I wrote an essay, I used Fangshen, hahahahaha]

[I wipe, this can also be used? 】

[What is brave or something, just put it up anyway, put it hard, put it hard, don’t put it on, it’s safe to put it on, although it’s uncomfortable, it’s guaranteed]

【Why do you feel this is getting more and more strange】

“People and animals generally follow the same paths, and these paths tend to twist and turn across the land.”

“If you come across a road that is often traveled by people or animals in the desert, you must follow it.”

“Don’t go in a straight line to avoid those turns. Because people or animals often travel this way with the fewest obstacles, and it’s often from shade to shade, and from water source to water source.”

“This trick is very useful in many environments, just like I followed the bison to find the salt mine in the rainforest, it may be dangerous, but it must be remembered that some desert animals do not drink water , but get enough water from their food.”

“You need to have enough experience and animal discrimination.”

“Always keep in mind, save your energy and water as much as possible, maximize your time and space, don’t work in hot weather, sweat will take away more body fluids, and you don’t necessarily have to find water, you must Balance the loss of fluids with the potential gains.”

“Depending on the environment, you can even make full use of the water source provided by cacti and various roots, and use the great temperature difference between day and night in the desert to condense water vapor to get water.”

[Yes, speaking of it, why haven’t I seen a cactus or something]

[Hey, when you said that, I also remembered it. It seems that Lao Fang has been away for so long and has never encountered a cactus. There are so many plants before, I have never seen it before]

“Because there are no cacti in the Sahara, no, I can’t say that there are no cacti. It can only be said that there are very few. After all, it is globalized, and it is normal for species to invade.”

Bi Fang glanced at the surrounding desert and explained.

This suddenly surprised everyone, because in their impression, desert and cactus are a pair of inseparable CPs!

“This is a common misunderstanding by normal people. Cacti are American plants, and they don’t survive in all deserts.”

“Cactus is a typical CAM plant, that is, a plant with sedum acid metabolism pathway, and it is mostly a serous plant. A simple understanding is that it is succulent, the leaves degenerate into needle-like, and the pores are closed during the day, reducing transpiration; the stem is thick and succulent, with The well-developed parenchyma cells store abundant water; the epidermis of the stem is protected by a thick, hard waxy…”

“Because of these abilities, it is resistant to hot and arid environments. In addition, the cactus has a huge root system, which can absorb the rainfall in the rainy season and store it in the body for use in the dry season. It will not live on the hot sand and die.”

“Mexico and the southern part of Chou country belong to the savannah climate. There are two distinct dry and wet seasons. The wet season is shorter. In the wet season, the cactus absorb a lot of water 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, Taklima is wet, although summer is hot and dry, but winter is cold, so it cannot reach the temperature conditions for cactus 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 belongs to a typical tropical desert climate. It is hot all year round, with scarce precipitation and poor water conditions, which cannot support the requirements of cacti for water storage. In addition, the temperature at night is usually below zero, so there is no Distribution of cacti.”

“But further north, offshore locations, such as Morocco, there are more cacti, and there are even cactus forests, which are still very shocking. You can go and have a look when you have time.”

[Okay, I will go when I have time (dog head)

[Shocked me for a whole year, I always thought that cactus and desert were normal configurations, what the hell, it turns out that not all of them have it]

[Indeed, this is also the first time I have heard of such a thing…]

【A little hanging】

[Fangshen knows so much]

[I will talk about the strong vitality of cactus in the future, can I refute it like this? 】

[Actually not, because it is still very strong (funny)]

The rainbow fart was blown again in the live broadcast room, but Bi Fang pulled the reins and sniffed lightly.

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

“A sandstorm is coming.”
