The 5 most threatened species by traditional Chinese medicine

Traditional Chinese medicine has boomed in recent years, thanks to increased purchasing power, especially Chinese Asian middle class. This ancient medicine is based on the concept of vital energy, that invades every corner of the body and organs, and can be acquired through ingested substances, as are parts of various animals. Despite numerous studies, there is no scientific evidence of its benefits to human health. In contrast, there is evidence of an alarming decline in populations of emblematic species such as tigers, rhinos or lions.

INTRODUCTION

3000 years ago emerged, within the Shang Dynasty, a type of medicine that would completely change the life and habits of the Asian people. The basis of traditional Chinese medicine have a strong philosophical component and focus on the concept of ‘Qi’ or vital energy. This energy flows inside the body through channels or meridians, which in turn are connected to organs and bodily functions. The ‘Qi’ regulates the spiritual, physical and emotional balance of the person, and can be altered when the Yin and Yang (negative and positive energy) get unbalanced. This imbalance and alteration of vital energy is what leads to all kinds of diseases.

Since ancient times, diseases have been fought with many remedies, many of them derived from animals. Almost any Asian species has been used for traditional medicine, such as cows, wasps, leeches, scorpions, antelopes, sea horses, dogs or snakes. Despite the zero scientific evidence of its benefits, its popularity has been increasing with the population explosion and the purchasing power of Asian countries, especially China and Vietnam. Many ‘new rich’ find in these products a way to distance themselves from other social classes and show off their new lifestyle. As a result, many species are in danger of extinction in the coming decades if nothing is done about it.

In this article we will have a look at the 5 most threatened species by Chinese medicine, and the actions that are being carried out to improve their situation.

THE 5 MOST THREATENED SPECIES BY CHINESE MEDICINE

Tiger (Panthera tigris)

The tiger is undoubtedly the most emblematic and admired animal by traditional Chinese medicine. Practically all its parts has been used, such as its nose, tail, eyes, whiskers, brain, blood and even penis. Each part has been associated with a particular cure. Eating your brain, for example, combat both laziness and pimples, while the eyes are used to treat malaria and epilepsy.

Unlike other animals used for traditional medicine, tiger parts are not only sold to Asian countries like China, Taiwan, Japan or South Korea, but also to occidental countries, even the United States and United Kingdom. In fact, in cities like London, Birmingham or Manchester you can find products that claim to contain tiger bone. The price of tiger bone is between 140 and 370 dollars per kg in the US, while a cup of tiger penis soup (that it is used to increase virility) reaches 320 dollars.

Although there are only  3,200 tigers in the wild (of the 100,000 existing a century ago), there are countries that contain tigers as Myanmar, Laos and Cambodia who have not yet signed the CITES agreement, which means that hunting is still legal. In the airport of Hanoi, for example, it is still possible to buy bones, organs and tiger skins without any difficulty.Te

Despite the ban on trade in tiger bones in China in 1993, the business of the tiger is still a very important business in the country. In fact, as pointed out by the researcher and writer Judit Mills in an interview of Yale Environment 360, from that year the number of tiger farms increased rapidly, reaching, at present, the number of 6000 tigers in these places. Most of these farms are dedicated to the growing business of tiger wine, symbol of high status and wealth among the Chinese population. The tigers are fed like cattle until they are killed to extract their bones, which will be immersed in rice wine. The longer they remain in the broth, the higher the price of the bottles.

Just over a month ago, a scandal involving tigers and traditional medicine splattered the Kanchanaburi Tigers Temple in Thailand. In there, more than 40 dead tiger babies were found in freezers, allegedly in order to deal with them on the black market that involves this mythical species.

Asian black bear (Ursus thibetanus) and sun bear (Helarctos malayanus)

Bear bile has been used in traditional Asian medicine for thousands of years. Yore, bile was extracted once the bear was dead, using its meat as well. However, since 1980 the popularity of this product grew, and a flourishing industry was settled and growing year after year. It is estimated that there are currently more than 12,000 bears in farms bile extraction in China and Vietnam.

Thanks to its high levels of ursodeoxycholic acid, bear bile can help to treat liver ailments and bladder. However, the extraction of bile causes to bears an unimaginable damage, both physical and psychological. In most cases, bears are confined in cages whose size is like a phone booth, and are continuously sedated so they do not give problems. Poachers make them a hole in the gallbladder and let it drip in order to extract the bile. This heinous practice is still legal in China, although 87% of the population disagrees with this practice.

Many lose much of their teeth by gnawing the bars continuously to try to escape, or attempt suicide punching themselves in the stomach.

White rhinoceros (Ceratotherium simum)

If we look back, it might seem that the situation of the white rhino is excellent. This African species was on the brink of extinction in the early twentieth century, when there were only 100 individuals. Fortunately, thanks to numerous international efforts, the species recovered surprisingly and currently has a population of about 20,000. However, the situation of rhinos is critical again, because of the poachers kill more than a thousand of them every year, which has reignited the alarms for this species.

The rhino (the Asian rhino in that time) has been hunted since the dawn of traditional medicine, as there are records of their hunting since 200 B.C. Horns, blood, skin and even urine have been used since ancient times as a remedy for various ailments such as nosebleeds, strokes, seizures and fever. Today, the main goal is his horn, which reaches exorbitant prices on the black market. A rhino horn can reach up to 46,000 euros per kilogram on the Asian black market, which has already been exceeded the price of gold. The business has prospered thanks to this great incentive, the ease of hunting these animals (they are slow, nearsighted and docile) and the lack of vigilance in the countries they live. The main destination for rhino horn is Vietnam, where the belief in their properties is stronger.

It surprises and scares simultaneously when comparing the only 13 deaths in 2007 with the nearly 1200 deaths occurred in 2015. Source: TRAFFIC.

Pangolin (family Manidae)

Probably, the hunt that has increased more in recent times is the pangolin hunting, especially in China and Vietnam, its main markes. They are hunted for their meat and scales, wich are used for traditional Chinese medicine as a remedy for all kinds of diseases: malaria, anziety,depression, asthma and even cancer. Of course, scientific investigations have found no evidence of health benefits, and it is very unlikey to occur, because their scales are made of keratin, the same material that forms our fingernails and hair, or rhino horns.

Much of the hunted pangolins come from Myanmar, a country that has become, unfortunately, a gateway for most hunted pangolins in Asia or Africa. According to TRAFFIC, in the period from 2010-2014 were seized, only in Myanmar, 4339 kg of pangolin scales and 518 dead bodies. In the Philippines, in April 2013, a fishing boat containing 10,000 kg of pangolin scales was seized, which amount of 20,000 to 25,000 pangolins. With a population in continuous decline, the situation is far from improving. It is no wonder: a hunter, which in many cases has enough to survive, can gain up to 1,000 euros for just a single pangolin.

Lion (Panthera leo)

Lion has been the latest to join this unfortunate list. It was once one of the most abundant larger cats on the planet, with an estimated population of more than 400,000 individuals in 1950. Nowadays, it is calculated a population of no more than 20,000 individuals, a fact that has placed them in the Red List species in the Vulnerable category.

Although the greatest threat for the lion is still habitat loss, the increase of protect measures for tigers in Asia and their low number has placed the lion as a new target for the mafias, as indicated in this 2015 Nature article. In 1995 it was documented for the first time the use of parts of lion in traditional medicine, when it was discovered several typically tiger products containing lion parts. In December 2009 the CITES agreement allowed the export of skeletons lion to Asia. It is estimated that from that date until the end of 2011 more than 1160 bodies of lions were exported, mostly to Laos and Vietnam. The main use of lion bones is to serve as a substitute of tiger bones as a sexual enhancers.

CURRENT STATUS OF LAWS AND ACTIONS AIMED TO PROTECT ILLEGAL HUNTING OF THESE SPECIES

  • Tiger: Many Asian nations such as China, Nepal, Japan, South Korea and Thailand have pledged to enact laws that prohibit trade of tiger products, preserving their habitat and form a regional network to stop the tigers trade. Hong Kong, which accounts for almost half of exports of tiger parts, has intensified controls, while Taiwan, thanks to a recent trade control law, conducted numerous seizures, arrests and extensive searches for illegal tiger parts.
  • Asian black bear and sun bear: By mid-2015 it was known that an important pharmaceutical Chinese was working on an alternative synthetic product for bear bile. This product could finally end up with the bear bile farms. However, it is still necessary the total abolition of this practice in China.
  • Rhinos: There is a strong debate about legalizing rhino horn trade in South Africa. Some NGOs believe that this would lead to a fall in prices on the black market, while others argue it would raise the demand and mafias would still control the market. TRAFFIC along with Save the Rhino International launched an awareness campaign in Vietnam to persuade consumers of rhinoceros horn to reject its use. In addition, TRAFFIC got the commitment from the Association of Traditional Medicine of Vietnam to promote the reduction of demand of rhino horns.
  • Pangolin: Trade with pangolins and parts is protected by law in Myanmar, the most affected country by illegal trade. In addition, Asian pangolins are included in Appendix II of CITES, which means that international trade is prohibited. China is increasing control of smuggling pangolin, and has already imposed tough penalties to pangolin traffickers.
  • Lions: They are listed in Appendix II of CITES, which means that trading of its parts is strictly controlled. Farms created for lion hunters are the main supply of bones for Chinese medicine, that means that, for now, this phenomenon is having little impact on wild populations.

Homosexuality is so animal

Fortunately for LGTB collective, greater and greater countries and societies understood that homosexuality is something natural and that it is not an illness. Anyway, despite this is true, it is also true that it is necessary to work hard to achieve equality on lesbian, gay, transexual and bisexual rights and to eradicate the false belief that homosexuality is unnatural. In the next weeks, in cities all over the world like Barcelona and Madrid will take place LGTB Pride parties. For this reason, this article hope to show clear examples that homosexuality is not exclusive of human, but present in many animals. So, there is no reason to continue believing in the argument that homosexuality is unnatural!

INTRODUCTION

Homosexuality is a fact present in many animal species. In fact, it has been documented in 1,500 of the more than 1 million described animal species (Bagemihl, 1999). Without going any further, a study of the California University demonstrated that in all the analysed species there were some individuals with homosexual traits or behaviours, including worms, flies, birds, dolphins and chimpanzees, among others.

In the animal kingdom, the concept “homosexuality” refers to any sexual behaviour between same sex animals, like copulation, flirt, mating, genital stimulation and young breeding. In the case of humans, it is more complex than this because there is much more factors and feelings are involved in this.

From the biological point of view, it is supposed that the goal of any species is its perpetuation. So, which is the function of homosexuality? There are many theories about it and they are not particular because for each species there is one explanation or another. Let’s explain three of them! Marelen Zuk, professor in biology at the University of California, propose that not producing their own offspring, homosexuals could help to breed and take care of their relatives, what also contributes to genetic pool. According to the biologist and phsycologist Janet Mann from the Georgetown University, it is a way of creating links and alliances between individuals. Finally, in the case of fruit fly and other insects, the evolutionary biologist Nathan Bailey suggest that the reason of their homosexuality is the lack of the gene that let them to distinguish between both sex. There is also the possibility that homosexuality doesn’t have any function. At any rate, homosexual behaviour may have evolutionary consequences, but it is still being studied.

PINGUINS

On February 2004, New York Times published that Roy and Silo, two male chinstrap penguins (Pygoscelis antarctica) from the Central Park Zoo, coiled their necks, vocalized one to other and had sex. When they were exposed to females, they rejected them. Moreover, zookeepers gave them a fertile egg in order they incubate them and when the little penguin was born they feed her until she was able to live by herself. This is not an isolated case because it have happened more in this and other zoos, like in Bremerhaven Zoo (Germany), Faunia (Spain) and Dingle Ocean World (Ireland).

But this is not exclusive of captive animals. A research done on Adélie penguin (Pygoscelis adeliae) found homosexual behaviours in some of their young individuals. Another research was carried on king penguin (Aptenodytes patagonicus), in which it was observed that 28.3% of males flirted with other males. The reason in this case seems to be an excess of males or high testosterone levels. Anyway, it was found two partners (male-male and female-female) in which one knew the vocalization of the other.

BONOBOS

The bonobo (Pan paniscus), apes very close to humans, are a good example of homosexual behaviours. They are so sexual. It has been observed that, in captivity or free, half of their sexual relationships are with same sex animals. In addition, females have sex with other females almost every hour. The main function of this is to strengthen links between animals. In the case of males, in order to reduce the stress after a fight, a penis fight takes place, that consists on rubbing their genitals together.

KILLER WHALES

Homosexual interactions between male killer whales (Orcinus orca) are an important part of their social life. When resident groups join together during summer and autumn to feed, males show flirting, affectionate and sexual behaviours between them. Normally, interactions take place one to one and lasts for an hour, but it can be longer. In this interactions, they caress, chase and carefully push one to the other. Another amazing behaviour is the beak – genital orientation, but it also take place between males and females. Just under the water surface, one male swims in an upside down position, touching the genital zone of the beak. Then, they dive together in a double helix spiral. This happens several times, but they interchange their positions. It is not strange to see them with the erected penis during this interaction. Despite it happens in all ages, it is specially abundant in young animals.

GUPPIES

A research made on guppies (Poecilia reticulata) demonstrated that the lack of females in the environment during a long period of time produce that males prefer other males even when there are females in the environment. Not only this. When males that had been with females during a long period of time are deprived from females for a short time (two weeks) they prefer males instead of females.

Male guppies prefer other males when there is no females in the environment during a long period of time (Picture from GuppyFish).

DRAGONFLIES

Some studies lay bare that there is a high rate of mating between same sex individuals in dragonflies. The reasons could be the lack of individuals of the other sex or that female tricks to avoid sexual advances of males could produce that males look for same sex individuals. One specific example is blue-tailed damselfly (Ischnura elegans), in which 17% of males of wild populations prefer male partners.

17% of male blue-tailed damselfly (Ischnura elegans) prefer other males (Picture: L. B. Tettenborn, Creative Commons).

SOME EXAMPLES MORE

  • Studies on wild occidental gull (Larus occidentalis) show that between 10 and 15% of females are homosexual. It has been seen that they show flirting rituals between them and that they set nets together. They only copulate with males to produce fertile eggs, but then go with their initial partner.
  • On domestic sheep, 8% of males from a flock prefer other males despite the presence of females. But this could benefit other males because they can present the same genes and pass to next generation. But this also benefits females by doing them more fertile.
  • The king of savannah, the lion, also have homosexual behaviours. It has been observed wild male and female lions with this behaviour, include mating.

  • In some species of seahorse, homosexual behaviours between females are frequent, more than heterosexual.

CONCLUSION

Homosexual behaviours are no only in humans, but they are more complex in people. The reason that lead to the development of these behaviours in animals are several: lack of females, to stablish harder links… but there are some examples in which the behaviour is permanent. Moreover, it has been seen that this behaviours are not artificial due to the captivity of animals, like humans in prison, but they haven in wild animals too. So, homosexuality happens in many animals and cannot be considered unnatural. In addition, if it is the result of natural forces it cannot be considered immoral.

Pangolin: poaching is condemning it to extinction

Neither the tiger or elephant or rhino: the most hunted mammals by humans are pangolins, to the point of critically threaten their survival as a species. Discover the only mammal with scales, its current condition and what can we do to prevent the extinction of all species of pangolin in the world.

WHAT IS A PANGOLIN?

The name pangolin (also known as scaly anteater or trenggiling) includes 8 different species distributed by a variety of habitats (tropical rainforests, dry forests, savanna areas, cultivated fields…) in Africa and Asia. They measure between 90 cm and 1.65 m. They are the only family in the order Pholidota: although physically similar, armadillos, sloths and anteaters are not its relatives (order Xenarthra). Most are nocturnal, solitary and shy, so there are still many questions about their biology and behavior in the wild (they don’t usually survive captivity).

MORPHOLOGY

Pangolins are the only mammals with scales: they are made of keratin (like our nails) and give them a look like a pineapple or artichoke. Scales are very sharp and they can move them voluntarily. If pangolins feel threatened hiss and puff, curl into a ball leaving the scales exposed and secrete pestilential acids to ward off predators (tigers, lions, panthers and humans).

The claws allow them both climb as digging: terrestrial pangolins hide and breed in underground galleries and arboreal pangolins do the same in hollows on trees. The tail of the tree pangolin is prehensile to attach to the branches. In addition, pangolins are excellent swimmers.
They are mainly bipedal animals: forepaws are so large that force them to walk on its hind legs, with a maximum speed of 5 km/h. Watch a pangolin walking and feeding:

NUTRITION

Pangolin has no teeth and is unable to chew. It feeds on ants and termites, which locates with its powerful sense of smell (the view is underdeveloped) and catch them with its sticky and long tongue (may be longer than the body itself, up to 40 cm). The stones swallowed involuntarily and corneal structures of their stomach help them to crush the exoskeletons of insects. With its powerful claws destroy their nests to access them and avoid their attack plugging his ears and nostrils, besides having an armored eyelid. It is estimated that a pangolin can consume about 70 million insects per year, which makes them important regulators of the population of ants and termites.

REPRODUCTION

Pangolins can reproduce at any time of the year. After pregnancy (two to five months, depending on species) only one young is born (African species) or up to three (Asian species).

The pangolin is born with soft scales, which begin to harden after two days. When after a month come out of the burrow, they travel on the tail of her mother and become independent at 3-4 months. Their lifespan is unknown, although in captivity an individual lived until 20 years old.

THREATS AND CONSERVATION

In addition to habitat destruction, the main threat that pangolins face is direct hunting for human consumption. Although there are international laws to protect them, it is estimated that about 100 000 pangolins are hunted annuallyGiven the defense strategy of this animal, poachers only have to catch them of the ground. Like other species, like sharks, the food market and traditional medicine are the main causes of directing the pangolin towards extinction.

WHY PANGOLINS ARE POACHED?

  • Bushmeat is considered a delicacy and an indicator of high social status in Vietnam and China. The pangolin fetus soup is sold as an elixir to increase virility and improve breast milk production. The price of bushmeat on the black market can reach $ 300 per kilo. The price of an individual can reach $ 1,000.

  • Blood is sold as a tonic to improve health and as an aphrodisiac.
  • Scales can reach $ 3000 per kilo and are used for almost anything: to cure from acne to cancer. This belief is curious, considering that the scales have the same structure as our fingernails.

All these purported medicinal and magical effects have no scientific basis, making yet more nonsense pangolin smuggling.

CONSERVATION

The population trend of all species of pangolin is declining in some cases to an alarming extent. The IUCN (International Union for the Conservation of Nature) Red List of Threatened Species classifies them as it follows:

RED LIS CATEGORIES IUCN

Because of their status, IUCN restored in 2012 a group of specialists within the Species Survival Commission (SSC) dedicated to pangolins (Pangolin Specialist Group -PangolinSG-). Its main objective are do research to increase knowledge of pangolins, the threats they face and how they can be mitigated to facilitate preservation.

The conservation projects that are being carried out include campaigns to reduce the demand of bushmeat and pangolin scales and the tightening of laws. Still, the total ignorance of populations’ state and low survival in captivity for breeding makes it difficult to design strategies for their conservation.

WHAT CAN YOU DO FOR PANGOLIN?

  • Reject any product derived from this animal, either bushmeat, scales or “miracle” products for the cure of diseases. Read the labels of any traditional remedies, especially if they are from the Asian market, and recall that its hypothetical benefits have no scientific basis, so that you can rethink their use.
  • Share information. If you own new data on pangolins, photos or videos contact with PangolinSG to cooperate with the investigation. Talk about them in your immediate environment to raise awareness and publicize this fantastic single animal.
  • Do a PhD about pangolins. Lot of research on these species is still needed, so if you are a student and you are planning to do a PhD, you can collaborate with PangolinSG with your future research.
  • Become a PangolinSG volunteer. Get involved in the development and implementation of projects and conservation programs.
  • Make a financial donation so PangolinSG can continue its work.

In conclusion, more scientific research, a change of mind and protection policies are needed to prevent the pangolin become an example of extinct species at the hands of ours, as it is about to happen to white rhino.
