Hundreds of elephants in Botswana have died, what exactly is the cause of death?

The cause of death of more than 300 elephants in Botswana should be the death of drinking water containing cyanobacterial toxins in the puddle, before the local investigation team also considered artificial poisoning, poaching, disease and other factors, but with the deepening of the investigation, they were ruled out step by step, and the final investigation results showed that due to the local climate change and rising temperature, the toxic cyanobacteria bacteria in the waterhole where the elephant often moved were overgrown, and the elephant should have been active in the waterhole for a long time, drinking water, which led to the poisoning.

Elephant Mortality PhenomenonIn the past few months, Botswana, the country with the largest number of elephants in Africa, has seen large-scale elephant deaths, the latest news has been that more than 350 elephants have died unnaturally, most of them fell in the area around the Okavango Delta, it is said that more than 70% of the elephant carcasses are close to the waterhole, so the investigators finally concluded that the death of the elephant is inseparable from the waterhole.

Strange phenomenonIt is normal for individual animals to die unexpectedly in nature, but large-scale animal deaths in a short period of time are relatively rare, and these elephants in Botswana also showed strange phenomena before they died: elephants, regardless of male and female, old and young, or prime elephants, all fell one after another near natural puddles; Some elephants seem to have lost their sense of direction before they die, and can only spin around wildly in place; Some elephants had difficulty even walking, and suddenly fell to their knees face down, and died suddenly; Usually when an animal dies in the wild, vultures fly to eat carrion, but the fallen carcasses of these elephants are rarely visited by vultures. Based on these strange phenomena, the investigation team believes that the elephant may have died of an unknown disease or that its nervous system was attacked.

The final investigation team of cyanobacteria took water samples from the puddle and sent them to laboratories in South Africa and the United States for testing, and found that these water bodies contained large amounts of cyanobacterial bacteria. Some species of cyanobacteria grow with toxic substances that can kill animals, so the team concluded that elephants drank large amounts of water containing cyanotoxins to cause their bad luck.

The current ** in Botswana indicates that the country's elephants, who died from toxins in the water produced by cyanobacteria. Since March this year, more than 300 elephants have died in Botswana, which has been investigated to be caused by cyanobacteria in the water, and samples sent to the laboratory have detected cyanobacterial toxins. And some witnesses responded that some elephants had repeatedly walked in circles when they died, which may be due to nerve damage to the elephant's brain.

As a result, local officials concluded that it was the cyanobacterial neurotoxin that caused the mass death of the elephants.

Cyanobacteria are widely distributed, growing in about 75% of the world's freshwater, and there are about 2,000 species of cyanobacteria in the world, and about 900 have been recorded in China. The harm of cyanobacteria to water bodies is mainly in nutrient-rich water bodies, where cyanobacteria bloom in large numbers and then produce green tides on the surface of the water. Green tides can cause water quality to deteriorate and deplete oxygen in water bodies.

And some cyanobacteria produce toxins that can affect people and animals to varying degrees. There are algal toxins in some cyanobacteria, which can be divided into hepatotoxins and neurotoxins according to the different ways of harm, and this time it is the neurotoxins produced by some cyanobacteria that harm Botswana elephants.

Toxin-producing cyanobacteria are not common, but in recent years, they have become more common due to global climate change driving up global temperatures. The rise in global temperature has brought various problems to humans and animals, but it is undeniable that a large part of global warming is caused by humans. The massive emission of greenhouse gases has caused the earth's temperature to rise, and with it comes a series of problems.

Melting glaciers, rising sea levels, more frequent extreme weather, and more. Eventually, the animals will also die as a result of the impact.

We can't afford to make animals pay for human fault time and time again. The earth is our only home, and it is urgent to care for the environment. Maybe if we only make a small change in our lives, this incident in Botswana will not happen, and they will be able to live leisurely on the earth.

Drinking water containing cyanobacterial toxins in a puddle caused death, and the local investigation team also considered factors such as artificial poisoning, poaching, and disease, but as the investigation deepened. The final investigation results showed that the local climate change and rising temperature caused the excessive multiplication of toxic cyanobacteria in the waterhole where the elephant often moves, and the elephant should have been in the waterhole for a long time to move and drink water, which led to the poisoning.

The main culprit in the death of hundreds of elephants is a bacterium, cyanobacteria bacteria, elephants are dying from the toxins produced by cyanobacteria, as climate change drives up global temperatures, the presence of toxic cyanobacteria is becoming more and more common, and the continuous high temperature and sufficient sunlight in summer can easily cause cyanobacteria outbreaks.

As a result of climate change, temperatures are particularly high in southern Africa, and water is getting warmer, which causes bacteria to multiply and produce more toxins, and elephants drink toxin-laden water, leading to death.

More than 350 elephants in Botswana died mysteriously! The cause of death is under investigation.

Since March this year, hundreds of elephants have died mysteriously in northwestern Botswana, Africa, and many elephants have been found near waterholes. The mysterious death of hundreds of elephants has made netizens talk about it.

One of the authors of the article, the famous South African zoologist Armanda Bastos, said that although no definitive conclusions have been drawn about the mysterious death of these elephants, malicious poisoning can basically be ruled out, because no other animals have been found to die nearby; It is also unlikely to be an illegal hunt, as the tusks are all intact; The likelihood of dying of starvation is not very high, as there is plenty of food available to the elephants; Judging by the condition of the elephant at the time of death, the possibility of anthrax infection has also been ruled out.

A local environmentalist in Botswana said, "In the absence of drought, such a mass death event is completely unprecedented." ”The age distribution and sex of the dead elephant herd are not consistent. According to the observation of the locals and the death posture of the elephants, some are lying flat on the ground, indicating that death is fast; Others paced in circles before dying, and the rate of dying was relatively slow.

And the health of some of the elephants that are still alive is not encouraging. And 70% of the elephants that die are near waterholes.

Botswana officials have previously issued a statement that they are stepping up their investigation into the cause of the strange death of the elephant herd, and samples of nine pesticides and chemicals commonly poisoned wild animals have tested negative, ruling out two suspected minerals or starvation-related elephant deaths. Regarding the mysterious death of the elephants, McCann, head of National Park Rescue, said: "It's horrible, we need to know what's going on."

Talking about the cause of death of elephants, he said that there may be many causes of elephant deaths, such as parasites unique to elephants, and even new crown pneumonia, which are still unclear.

Hundreds of elephants in Botswana, Africa died mysteriously, and experts have ruled out the possibility of artificial poisoning, so the most likely cause of death is disease or virus raging in the elephant herd, resulting in the collective death of hundreds of elephants!

Hunted by criminals. Ivory is a rare item, and many criminals take risks to hunt elephants for profit, which must be severely punished.

For the time being, the cause of death of these elephants has not yet been ascertained, but the damage caused to Botswana is very serious.

Because of the rapid development of human beings, most of the natural environment has been destroyed, thus casting a shadow of death on the earth.

In a situation like this, there is no way to tell if this is man-made or natural, but there is always a reason for it, and it should be investigated to avoid such a situation from happening again.

This is because many people are not highly conscious, which leads to the wanton killing of elephants, and the current ecological environment is also deteriorating, so this situation has occurred.

It is very likely that this death was caused by some disease, but the current methods of human beings are still uncertain, and it is also possible that the death of elephants is caused by some new virus.

Botswana is home to the world's largest elephant population, but will the recent elephant deaths in Botswana cause panic and harm to human health? I think there may be a possible reason for the epidemic, which caused the elephant to be infected with the virus and cause death, and it is possible that it has also become a hunter's thing, but because there are only elephant deaths in Botswana, not in neighboring countries, and it is possible that the elephants are poisoned and killed by the blue-green algae bacteria in the water, all of which pose a threat to the safety of elephants.

1. Affected by the epidemic.

In the face of the death of elephants in Botswana, I can't help but wonder if the epidemic has affected the elephants and infected them with the virus, which is very scary, and at the same time, it will also bring the virus to other creatures in Botswana, seriously affecting the health of Botswana residents.

2. Massive plundering by hunters.

Most of the local hunters use poisoning to attack elephants, in the face of so many elephants, poachers will inevitably hunt elephants, because only Botswana's own elephants have died, and in neighboring countries it has not happened, it is likely to be poaching by poachers, this behavior will endanger more elephants, in elephant settlements, we should protect the safety of elephants, poaching is strictly prohibited.

3. Bacterial poisoning of cyanobacteria in water.

In the water where elephants live, cyanobacteria accumulate all year round, and cyanobacteria bacteria can also produce toxins, which pose a threat to the safety of organisms, which is equivalent to a chronic poison, in daily life, slowly invade the inside of the elephant's body, slowly weaken the elephant's body resistance, and eventually lead to the bizarre death of the elephant, this reason also exists, slowly strangling the elephant's body, and eventually leading to the death of the elephant.

1. Forests have been destroyed and elephants have lost their habitat; 2. The local climatic conditions have deteriorated, and it is difficult for elephants to survive; 3. There is a phenomenon of indiscriminate hunting and killing of elephants in the local area.

In the south of Africa, there is a country called Botswana, a development of such a country, and it is also one of the important ones of the whole country. But I didn't imagine that now an elephant has performed a corresponding death event, and the number of such a death is already very large, because before the elephant dies, it cannot carry out a corresponding transformation. At the same time, in the face of such a thing, we know that it is impossible to imagine it.

And such an elephant, its whole, in the process of a thing, is because it is in the whole process of this thing, because it is not able to carry out a corresponding direction, so it is said that such a death will be caused. <>

So we can see that the current result is that the predators kill one by one, and the poaching of elephants in Africa is also very serious. This is also a question of a related animal, the white tiger. It's not that some people are driven by this interest and so they will do such a thing, and we can also carry out an understanding.

And for such a problem now, it can be seen that they are very difficult to understand. At the same time, it is also possible that they have a related virus, which is why they are in such a situation。And the virus is also spreading violently among this one animal.

If such a problem occurs, for an elephant, such a thing will happen, we also take the past to make a corresponding understanding, but we all go to an imagination, that is, now facing such a whole agent, there is an environment in which such a thing will happen, but it makes people feel very incomprehensible, so it can be seen, That is to say, there is still a related problem in such an overall operation environment. <>

At the same time we can you come to a conflict that is related to a local elephant and an animal. If it is said that because the elephant eats a local crop, and it has a related impact on the elephant, this is also a reason that we can all understand. And the specific reason is also a related scientist to conduct a topic investigation.
