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.

Madagascar: a paradise in danger

The country is suffering a great social, political and ecological crisis which is threatening the survival of much of its biodiversity, unique in the world. Selective logging of Madagascar rosewood is causing a biological crisis unprecedented in the country. Lemurs, one of the most affected groups, are treading on thin ice.

INTRODUCTION

When the French botanist Jean-Henri Humbert set foot on the massif of Marojejy for the first time, in 1948, he was so astonished of what he saw that 7 years later he published Une merveille de la nature à Madagascar, a book which exalted the incredible biodiversity and pristine forests present in the region1. The fact is that Marojejy is possibly the best example of the rich and varied fauna and flora that Madagascar holds and, hence, the best indicator to take notice when the island begins to show signs of collapse. Unfortunately, both the region and the whole of Madagascar live days of uncertainty, and the fear of the disappearance of this treasure is becoming more real day after day.

Madagascar, the world’s fourth largest island, has an area of just over the Iberian Peninsula and contains a unique biological wealth. Despite its size and the relative proximity to the African continent, it has remained isolated from other continents since 80 million years ago, causing the local flora and wildlife have evolved independently from the rest. As a result, more than 90% of Madagascar’s species are considered unique in the world2. A 90% of reptiles3, 60% of birds4 and 80% of the island flora5 are endemic, as well as some unique lineages of mammals such as lemurs and fossas. However, all are at imminent risk of extinction due to the events experienced in the country in the recent years.

CAUSES OF THE ECOLOGICAL CRISIS IN THE COUNTRY

Deforestation has been present on the island since its colonization by humans, approximately 2000 years ago. However, in recent years, the delicate political situation in the country has led to their forests to their limits. With an unprecedented population growth, an extreme poverty (one of the highest in the world 6, 7) and a pressing political crisis, the nature of the island is helpless and besieged by multiple fronts. In addition to the traditional system of slash and burn deforestation, which allows local people to open forests to cultivate, it has appeared an unexpected player led by international companies. Selective logging of species of the genus Dalbergia (rosewood), rare in the forests and precious in the developed world due to its characteristic color and the strength of its wood, has become the main threat for the biodiversity of the island. It must be added, to the direct impact that involves the extraction of specific species of forest, resulting threats that can be even more damaging for the biodiversity, such as poaching, opening roads, habitat alteration, introduction of invasive species or intimidation of local populations by criminal organizations that manage the illegal exploitation8.

Selective logging, present and endemic for decades, took a breather in 2000, thanks to its ban in National Parks. However, due to a deep political crisis occurred in 2009, which ended with a coup d’etat, the situation got out of hand, and criminal organizations took control, entering with impunity in the National Parks of the country9. Many of these National Parks are literally being swept away and looted, and they are nothing more than a mirage of what they were once. Despite the restoration of democracy in 201310 and the promises of the elected president to end the “plague” that selective logging of rosewood was causing to the country11, nothing is being done to fight against poaching.

WHICH COUNTRIES ARE BEHIND POACHING?

China is by far, the major importer of illegal timber from Madagascar. The main reasons are the growth of its middle class, which demands new furniture in line with their new standard of living, and the facilities granted by China due to its lax legislation on illegal timber12. A considerable part of this wood is used to make furniture in the style of the Ming Dynasty, which can be sold for $ 20,000. As there is no control on the illegal timber entering to the country, it is impossible to trace their origin. That’s why, in many cases, furniture and musical instruments manufactured in Europe or North America have been made with some or all with illegal timber13.

BIODIVERSITY IN DANGER

Due to the opening of roads to remove rosewood timber, lemurs and other native species have become the target of poachers. At the beginning of the political crisis of 2009, a huge amount of lemurs and other wildlife were hunted to feed the thousands of loggers who often live in the forest while carrying out the logging. However, later, a luxury market which involved lemurs emerged, supplying restaurants with its meal in the larger cities and selling them as a delicacy.

Although the amount of death lemurs at the hands of poachers is unknown, there are many species that are suffering the impact, many of them in serious danger of extinction like the indri lemur -the largest lemur alive-, the Tattersall’s sifaka or the silky sifaka. The latter, has just a population estimated of 300 individuals. The situation of lemurs is so dramatic that a study of 2012 warned that 90% of the 103 species of lemurs should be on the Red List14. In addition, 23 of them should be qualified as Critically Endangered, the highest threat level.

During this time it has also been an increase of trade of wild animals to serve as exotic pets, mainly affecting chameleons and turtles15, but has also been intensified the smuggling of lemurs16. In fact, a study of 2015 estimated that the number of lemurs captured in freedom for the exotic pet market could reach the creepy number of 28,000 in the last 3 years17.

IS THERE ANY LONG TERM SOLUTION?

There is always a way to make things get better. Here there is some of them:

  • Avoid selective logging of rosewood should be the number one priority to reduce the collateral damage it generates. Since 2011 the Malagasy species of the genus Dalbergia belong to CITES Appendix 3, granting them a greater degree of protection and regulating their trade. However, the controls remain inefficient and wood is coming from Madagascar towards the ports of China. In 2013, CITES urged China to increase controls in ports, but nothing was done about it. As indicated in this 2015 article of The guardian18, illegal timber from Madagascar continues entering in large amounts, because Chinese law allows importing timber without requiring export permits.
  • Effective monitoring forest by independent observers could yield results. In fact, this system has already been implemented in countries such as Cambodia and Cameroon, achieving good results19.
  • DNA fingerprinting is another method that it has recently been used on confiscated ivory to determine which populations of African elephants are being hunted. DNA testing has already been applied recently to track limber in other countries20.
  • Finally, it is necessary that each and every one of us avoid purchasing exotic pets from Madagascar if there is no legal certification that tells us we are not damaging them.

With all these solutions, an increase of public awareness and a greater international responsability regarding environmental problems, it may still has a glimmer of hope for wildlife in Madagascar.

Bearded vulture: conservation of a unique bird

Last month a bearded vulture was born for the first time in Spain of parents bred in captivity and reintroduced into the wild. The bearded vulture is the only bird in the world that feeds almost exclusively on bones. Like the Iberian lynx, it is one of the emblematic animals of the Iberian Peninsula and it is endangered, so it is subject to various conservation and reintroduction programs. In this article, we encourage you to find out more about the bearded vulture and the spanish conservation projects.

DESCRIPTION

The bearded vulture (Gypaetus barbatus) is a diurnal bird of prey popularly included in what is called vultures, scavenger and ghoul birds (they feed on dead animals). However, the bearded vulture is quite different from other vultures:

  • It is so highly specialized that 85% of their diet are bones (osteophague) of dead mammals such as wild ungulates (chamois) and domestic cattle (goats, sheep). It can swallow bones up to 25 cm, and if they are too large catches them, rises them to 20-40 m and crashes bones against the rocks into smaller pieces that can swallowIt also uses the same technique to break tortoise shells.
  • It is very large, with a wingspan up to 2.8 meters and a weitgh up to 7 kg.
  • In general it isn’t noisy: it just whistles if it is excited or during the mating season.
  • It hasn’t the typical plucked vulture head. Vultures have a few or no feathers on their heads to maintain an optimum hygiene after putting their head in dead animals. Due to its peculiar diet, the bearded vulture has more feathers on head and neck, with its characteristic beard” below the peak.
  • The plumage is the same for both sexes but changes with age. The typical reddish and yellowish adults plumage is due to their habit of bathing in mud rich in iron oxides, otherwise they will had a white breast.

In this video (5 minutes, catalan) you can see bearded vultures in flight, breaking bones, engulfing them, raising a chick in the nest and bathing in mud.

REPRODUCTION

Bearded vultures nests on ledges and natural rock caves in the mountainous and rugged areas where they live. They have stable partner for life from age 7 and the reproductive cycle has different stages:

  • Pre-laying (September to November): nest building (covering it with branches, wool, feathers, bones ), defense of territory and sexual activity.
  • Incubation (December-February): they lay one or two eggs with a time difference of 6 days. Both sexes participate in the incubation for 53 days.
  • Nurturing (March-August): the largest chick kills his brother (fraticidal violence) to ensure survival. Parents provide food and when the chick leaves the nest (June-July), learn from them to find and prepare food until their emancipation.
  • Emancipation (January): displacement (thousands of kilometers) and dating back to the land where it was born to breed (philopatric instinct).

DISTRIBUTION

Subspecies Gypaetus barbatus meridonalis is distributed by the South and East Africa, while Gypaetus barbatus barbatus by North Africa and parts of Eurasia (see map).

In the Iberian Peninsula is found naturally only in the Pyrenees (Catalonia, Aragon and Navarra). Spain is the European country with more breeding couples registered (about 130, 2014 data).

THREATS

Bearded vulture populations are declining. It is ranked globally asnear threatened” in the IUCN Red List and “endangered” in the Spanish Catalogue of Endangered Species. Current threats they face are:

  • Death by poisoning (illegal baits, poisoned animal consumption, consumption of remains of lead hunting ammunition plumbism).
  • Death by electrocution or collisions with power lines and wind turbines of wind farms.
  • Poaching
  • Habitat loss and decreasing of reproductive efficiency because of the humanization of the medium (urbanisation, adventure sports )
  • Reduction of food (cattle in stables, obligation to bury the corpses )

CONSERVATION IN SPAIN

Due to the limited distribution of populations, their low number and difficulty to colonize new territories, in 2014 thirteen autonomous communities signed a protocol for the recovery of vultures in Spain. The most prominent action of this protocol is to strengthen the National Strategy for the Conservation of the Bearded Vulture in Spain (started in 2000) and the Programme Captive Breeding (2001), with actions such as the revaluation of rural areas, supplementary feeding and support for traditional farming practices. This strategy also involves the reintroduction in historic areas where the bearded vulture has been extinguished:

WHAT IS HACKING?

Hacking or rural upbringing is a technique that involves the release of captive-bred animals in an area that the bird assimilates as its birthplace. If successful, the bearded vulture returns to settle and breed. This technique did not has a conservationist origin, since it was developed by falconers in the Medieval Age. Falconry (hunting with birds of prey) are also currently used for wildlife control at airports or cities.

In falconry hacking consists in lefting in an elevated cage chicks that can feed by themselves. Falconer feeds them without being seen. After a few days they open the cage, using it as a basis for learning to fly. They are still feeding them until they learn to hunt by themselves and leave the cage. The young ones connect the cage as its birthplace so it will always return.

The center managed by the Gypaetus Foundation is based on the natural breeding, with minimal human intervention. Parents raise and feed their young from the second week of hatching. To monitor the nests a video surveillance system is used.

Since 2006, 31 bearded vultures have been released from captive breeding and each one is tracked by GPS transmitters. Currently 15 individuals are still sending signals (9 were killed and 7 stopped working). As said in the introduction, the good news is that last month was born the first chick result of released individuals (Tono and Blimunda) by hacking technique.

For more information, check out this documentary (in spanish) about the bearded vulture and its conservation (El bosque protector. Fauna amenazada, El Quebrantahuesos, 29 minutes).

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:

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.
