Four Countries Are Home to Two-Thirds of the Planet’s Primates—and Most of Those Are Endangered
By Jason Bittel
At last count, there were 505 nonhuman primate species living in the wilds of 90 countries across the globe. That might make you think of Earth as the Planet of the Apes (plus monkeys, lemurs, tarsiers and lorises), but according to a large study published last month, those statistics are a little misleading.
In truth, just four nations—Brazil, Madagascar, Indonesia and the Democratic Republic of the Congo (DRC)—harbor 65 percent of all primate species. And nearly two-thirds of the primates living in those hot spots (we'll call them the Big Four) are facing extinction.
Primates can be loosely defined as mammals with opposable thumbs, but they come in all sizes and dispositions, from timid, one-ounce pygmy mouse lemurs to stately, 550-pound Grauer's gorillas, to drunk 12-pound vervets. And the places these animals call home are just as diverse. Let's see how the humans in the four most primate-heavy countries are managing (or failing) to save their cousins.
Big, Beautiful Brazil
That more primates—crested capuchins, dwarf marmosets, red-bellied titis, sakis, uakaris, night monkeys and so on—live in Brazil than anywhere else should come as no surprise. The South American country is nearly as large as the U.S., and within its borders lies 60 percent of the Amazon rainforest, which accounts for more than half of all the rainforest left on Earth.
Unfortunately, Brazil allowed agriculture and timber operations to clear 114 million acres of this prime primate habitat between 2001 and 2016—the largest loss of forest over that period among the Big Four. (The next closest, Indonesia, lost half as much.) Even more concerning, Brazil has recently shifted toward more environmentally exploitative government policies and looser conservation laws, which scientists suspect will lead to even more deforestation.
Mining is also threatening Brazil's primates, and not only because it's tearing up the land. A 2017 study found that the country has at least 126 dams holding back mining-contaminated water and that these structures are "vulnerable to failure in the forthcoming years." And when these dams do burst, they befoul every waterway for hundreds of miles downstream with a wave of toxic sludge. (Mining dam collapses are dangerous for non-endangered primates, too. Twenty people died in 2015 when a large mine-tailings dam collapsed on the Doce River.)
But for all of Brazil's environmental woes, the country is also full of hope. According to Russell Mittermeier, coauthor of the new study and chair of the IUCN Species Survival Commission Primate Specialist Group, Brazil is the most successful among the Big Four at maintaining its primate diversity. He attributes this to the work of the country's large community of primate conservation professionals.
Take the northern muriquis, the largest monkeys in the New World. Also known as wooly spider monkeys, they can grow to more than four feet tall, and people often hunt them for meat. Further, the large tracts of Atlantic forest they once inhabited have been sliced and diced to the point where only pockets of the monkeys remain.
But in recent decades, organizations like the Muriqui Institute for Biodiversity, the Pro-Muriqui Institute and the National Institute of the Atlantic Forest have formed to give these monkeys a boost. While northern muriquis are still critically endangered, one population has risen from just 22 individuals to at least 354 as of 2015. (For a related Brazilian primate success story, check out my earlier piece on golden lion tamarins.)
Brazil is also capable of halting its deforestation habits and has done so in the past. From 2005 to 2012, the country reduced its rate of forest loss by a whopping 80 percent.
Brazil is the architect of its own destiny, for good or ill, but as of now, Mittermeier thinks it will tip toward the good. "It's the country where we have the highest likelihood of keeping all known species and subspecies into the next century," he said.
DRC's Future Is Very Much TBD
Gorillas, chimpanzees, monkeys and the most adorable of the adorable (though a bit gross), bushbabies, all call the Democratic Republic of the Congo home—as does one of the world's fastest growing human populations. The mountainous jungles of this large central-African nation are lush, but rampant government corruption and myriad warring factions run just as thick here. Together, these factors make the DRC the most worrisome of the Big Four.
The DRC has some of the planet's most important great ape conservation areas—places like Virunga National Park, home to the mountain gorillas that Dian Fossey made famous and Kahuzi-Biega National Park, where you'll find the rare Grauer's gorilla (as few as 17,000 are thought to remain).
As in the other Big Four nations, logging and agriculture threaten the DRC's wildlife, but poaching is the biggest problem here. Almost every primate known to inhabit this country has at some point ended up for sale in its bushmeat markets—even the tiny talapoin, which weighs about as much as a teacup Yorkie. At a single market in Kisangani, the country's third-largest city, one study found more than 8,500 primates over the course of four months—including many critically endangered ones, such as the Dryas monkey and, yes, the Grauer's gorilla.
It's likely that several of the products you own are adding to the loss of primates in the DRC. The country produces more than half of the world's cobalt, which is a key component in the lithium ion batteries that power smartphones, computers and electric cars. In just the past five years, demand for cobalt to fuel these industries has tripled, and experts expect it to double again by 2020.
The cobalt mining industry brings more roads, more deforestation and more workers looking for relatively easy sources of protein into the DRC's otherwise remote forests. A study from 2017 estimated that 8 to 10 million people make a living each year at these surface mines—and that translates to a lot of primates on the plate.
While corruption and lack of government accountability are rife in the DRC, even here there is hope. A recent census of the mountain gorillas Dian Fossey studied shows that the gorilla's numbers have actually increased since 2010, making it the only great ape population on Earth proven to be on the upswing.
Madagascar's on Its Own
The African island of Madagascar has the luxury of sharing precisely zero land borders with another country. This is good news in some ways, as it means the island's wildlife is protected from violent conflicts and from poachers spilling over from neighboring countries (as happens on the DRC-Rwanda border and the Brazil-Colombia border). But islands come with their own biodiversity risks.
The landmass now known as Madagascar separated from the Seychelles and India between 84 and 95 million years ago and it boasts an array of species found nowhere else on Earth. This includes five families of primates made up of 15 different genera and 111 species and subspecies.
"Madagascar is far and away the highest major primate conservation priority in the world," said Mittermeier.
But he notes that 90 percent of its natural habitats have already disappeared, thanks to agriculture and logging over the past century. "You have all of this incredible primate diversity found nowhere else in an area about the size of three New Jerseys," he said. "And New Jersey is not a very big state."
The Malagasy government has done very little to enforce its own environmental laws. Fortunately, local communities and NGOs are taking matters into their own hands. For instance, the only way tourists can gain access to the Andasibe-Mantadia National Park—home of the indri, one of the world's largest living lemurs—is by hiring a local guide.
NGOs are also taking the reins to save the critically endangered golden-crowned sifaka. About 6,000 of these cream-colored beauties remain in the northern stretches of the island, where forest fragmentation has greatly reduced their habitat. A local Malagasy NGO known as Fanamby teamed up with Conservation International in 2005 to secure a 49,000-acre protected area for the sifaka. Their numbers continue to decline, but so long as there are protected forests, there is hope.
Indonesia Is a Mixed Bag
Last comes Indonesia, a nation of more than 17,000 islands in the Pacific. Known for its orangutans—some of which have lost more than half of their habitat over the past 16 years to palm oil plantations—Indonesia is also home to googly-eyed tarsiers, lanky gibbons and lovely little langurs.
The country also has the largest population of Muslims on Earth—which is good news for its primates for one simple reason: Primates aren't considered halal, so Muslims usually won't eat them.
But while Indonesian primates have dodged the dinner plate, they have not escaped habitat destruction. Widespread clearing of tropical forests for palm oil and timber has put many primates here on the ropes. Without their natural homes, the animals sometimes seek food and shelter near human communities, where they are viewed as garden pests and killed. Weighing up to 220 pounds, orangutans are particularly conspicuous crop raiders, and when found, they're often shot.
The endangered Javan gibbon, also known as the silvery gibbon, is also running out of room to roam. Logging has pushed these animals out of the lowlands they prefer and into higher elevations, but there's obviously a limit to how high the gibbons can go and still survive. At most, only about 4,000 silvery gibbons remain, and some scientists estimate that their habitat has been reduced by up to 98 percent in all.
Still, conservationists aren't giving up on the gibbon yet. They are about to release into the wild a half dozen silvery gibbons that were born in captivity. It's not a magic bullet, but each primate returned to the wild population helps expand genetic diversity and gives the species a tiny boost toward staving off extinction.
As to where the Indonesian government stands on primate conservation, the timbre of a recent news story is not encouraging. The country is set on a massive hydroelectric dam project and appears to be actively downplaying concerns about the effect its construction could have on Tapanuli orangutans, a species discovered just last fall and already feared to be endangered.
The Good News?
Realizing so many of our cousins face so many existential threats of our own making can be disheartening, but there is one silver lining: No primate has gone extinct in more than 100 years. (There have been some close calls, though. For instance, the Bouvier's red colobus monkey was thought to be extinct until scientists rediscovered it in 2015.)
"This is the only larger group of mammals for which we did not lose at least one species or subspecies in the 20th century," said Mittermeier. The question now is, can we make it another 100 years with our family tree intact?

The patient in the case report (let's call him Tom) was 54 and in good health. For two days in May, he felt unwell and was too weak to get out of bed. When his family finally brought him to the hospital, doctors found that he had a fever and signs of a severe infection, or sepsis. He tested positive for SARS-CoV-2, the virus that causes COVID-19 infection. In addition to symptoms of COVID-19, he was also too weak to move his legs.
When a neurologist examined him, Tom was diagnosed with Guillain-Barre Syndrome, an autoimmune disease that causes abnormal sensation and weakness due to delays in sending signals through the nerves. Usually reversible, in severe cases it can cause prolonged paralysis involving breathing muscles, require ventilator support and sometimes leave permanent neurological deficits. Early recognition by expert neurologists is key to proper treatment.
We are neurologists specializing in intensive care and leading studies related to neurological complications from COVID-19. Given the occurrence of Guillain-Barre Syndrome in prior pandemics with other corona viruses like SARS and MERS, we are investigating a possible link between Guillain-Barre Syndrome and COVID-19 and tracking published reports to see if there is any link between Guillain-Barre Syndrome and COVID-19.
Some patients may not seek timely medical care for neurological symptoms like prolonged headache, vision loss and new muscle weakness due to fear of getting exposed to virus in the emergency setting. People need to know that medical facilities have taken full precautions to protect patients. Seeking timely medical evaluation for neurological symptoms can help treat many of these diseases.
What Is Guillain-Barre Syndrome?
Guillain-Barre syndrome occurs when the body's own immune system attacks and injures the nerves outside of the spinal cord or brain – the peripheral nervous system. Most commonly, the injury involves the protective sheath, or myelin, that wraps nerves and is essential to nerve function.
Without the myelin sheath, signals that go through a nerve are slowed or lost, which causes the nerve to malfunction.
To diagnose Guillain-Barre Syndrome, neurologists perform a detailed neurological exam. Due to the nerve injury, patients often may have loss of reflexes on examination. Doctors often need to perform a lumbar puncture, otherwise known as spinal tap, to sample spinal fluid and look for signs of inflammation and abnormal antibodies.
Studies have shown that giving patients an infusion of antibodies derived from donated blood or plasma exchange – a process that cleans patients' blood of harmful antibodies - can speed up recovery. A very small subset of patients may need these therapies long-term.
The majority of Guillain-Barre Syndrome patients improve within a few weeks and eventually can make a full recovery. However, some patients with Guillain-Barre Syndrome have lingering symptoms including weakness and abnormal sensations in arms and/or legs; rarely patients may be bedridden or disabled long-term.
Guillain-Barre Syndrome and Pandemics
As the COVID-19 pandemic sweeps across the globe, many neurologic specialists have been on the lookout for potentially serious nervous system complications such as Guillain-Barre Syndrome.
Though Guillain-Barre Syndrome is rare, it is well known to emerge following bacterial infections, such as Campylobacter jejuni, a common cause of food poisoning, and a multitude of viral infections including the flu virus, Zika virus and other coronaviruses.
Studies showed an increase in Guillain-Barre Syndrome cases following the 2009 H1N1 flu pandemic, suggesting a possible connection. The presumed cause for this link is that the body's own immune response to fight the infection turns on itself and attacks the peripheral nerves. This is called an "autoimmune" condition. When a pandemic affects as many people as our current COVID-19 crisis, even a rare complication can become a significant public health problem. That is especially true for one that causes neurological dysfunction where the recovery takes a long time and may be incomplete.
Though there is clear clinical suspicion that COVID-19 can lead to Guillain-Barre Syndrome, many important questions remain. What are the chances that someone gets Guillain-Barre Syndrome during or following a COVID-19 infection? Does Guillain-Barre Syndrome happen more often in those who have been infected with COVID-19 compared to other types of infections, such as the flu?
The only way to get answers is through a prospective study where doctors perform systematic surveillance and collect data on a large group of patients. There are ongoing large research consortia hard at work to figure out answers to these questions.
Understanding the Association Between COVID-19 and Guillain-Barre Syndrome
While large research studies are underway, overall it appears that Guillain-Barre Syndrome is a rare but serious phenomenon possibly linked to COVID-19. Given that more than 10.7 million cases have been reported for COVID-19, there have been 10 reported cases of COVID-19 patients with Guillain-Barre Syndrome so far – only two reported cases in the U.S., five in Italy, two cases in Iran and one from Wuhan, China.
It is certainly possible that there are other cases that have not been reported. The Global Consortium Study of Neurological Dysfunctions in COVID-19 is actively underway to find out how often neurological problems like Guillain-Barre Syndrome is seen in hospitalized COVID-19 patients. Also, just because Guillain-Barre Syndrome occurs in a patient diagnosed with COVID-19, that does not imply that it was caused by the virus; this still may be a coincident occurrence. More research is needed to understand how the two events are related.
Due to the pandemic and infection-containment considerations, diagnostic tests, such as a nerve conduction study that used to be routine for patients with suspected Guillain-Barre Syndrome, are more difficult to do. In both U.S. cases, the initial diagnosis and treatment were all based on clinical examination by a neurological experts rather than any tests. Both patients survived but with significant residual weakness at the time these case reports came out, but that is not uncommon for Guillain-Barre Syndrome patients. The road to recovery may sometimes be long, but many patients can make a full recovery with time.
Though the reported cases of Guillain-Barre Syndrome so far all have severe symptoms, this is not uncommon in a pandemic situation where the less sick patients may stay home and not present for medical care for fear of being exposed to the virus. This, plus the limited COVID-19 testing capability across the U.S., may skew our current detection of Guillain-Barre Syndrome cases toward the sicker patients who have to go to a hospital. In general, the majority of Guillain-Barre Syndrome patients do recover, given enough time. We do not yet know whether this is true for COVID-19-related cases at this stage of the pandemic. We and colleagues around the world are working around the clock to find answers to these critical questions.

One of the initial reasons social distancing guidelines were put in place was to allow the healthcare system to adapt to a surge in patients since there was a critical shortage of beds, ventilators and personal protective equipment. In fact, masks that were designed for single-use were reused for an entire week in some hospitals.

Unity Task Forces formed by presumptive Democratic presidential nominee Joe Biden and Sen. Bernie Sanders unveiled sweeping party platform recommendations Wednesday that—while falling short of progressive ambitions in a number of areas, from climate to healthcare—were applauded as important steps toward a bold and just policy agenda that matches the severity of the moment.
"We've moved the needle a lot, especially on environmental justice and upping Biden's ambition," said Sunrise Movement co-founder and executive director Varshini Prakash, a member of the Biden-Sanders Climate Task Force. "But there's still more work to do to push Democrats to act at the scale of the climate crisis."
The climate panel—co-chaired by Rep. Alexandria Ocasio-Cortez (D-N.Y.) and former Secretary of State John Kerry—recommended that the Democratic Party commit to "eliminating carbon pollution from power plants by 2035," massively expanding investments in clean energy sources, and "achieving net-zero greenhouse gas emissions for all new buildings by 2030."
In a series of tweets Wednesday night, Ocasio-Cortez—the lead sponsor of the House Green New Deal resolution—noted that the Climate Task Force "shaved 15 years off Biden's previous target for 100% clean energy."
"Of course, like in any collaborative effort, there are areas of negotiation and compromise," said the New York Democrat. "But I do believe that the Climate Task Force effort meaningfully and substantively improved Biden's positions."
Today the 6 Biden-Sanders Unity Task Forces are unveiling final language. The Climate Task Force accomplished a gr… https://t.co/gz3broq2qe— Alexandria Ocasio-Cortez (@Alexandria Ocasio-Cortez)1594240617.0
The 110 pages of policy recommendations from the six eight-person Unity Task Forces on education, the economy, criminal justice, immigration, climate change, and healthcare are aimed at shaping negotiations over the 2020 Democratic platform at the party's convention next month.
Sanders said that while the "end result isn't what I or my supporters would've written alone, the task forces have created a good policy blueprint that will move this country in a much-needed progressive direction and substantially improve the lives of working families throughout our country."
"I look forward to working with Vice President Biden to help him win this campaign," the Vermont senator added, "and to move this country forward toward economic, racial, social, and environmental justice."
Biden, for his part, applauded the task forces "for helping build a bold, transformative platform for our party and for our country."
"I am deeply grateful to Bernie Sanders for working with us to unite our party and deliver real, lasting change for generations to come," said the former vice president.
On the life-or-death matter of reforming America's dysfunctional private health insurance system—a subject on which Sanders and Biden clashed repeatedly throughout the Democratic primary process—the Unity Task Force affirmed healthcare as "a right" but did not embrace Medicare for All, the signature policy plank of the Vermont senator's presidential bid.
Instead, the panel recommended building on the Affordable Care Act by establishing a public option, investing in community health centers, and lowering prescription drug costs by allowing the federal government to negotiate prices. The task force also endorsed making all Covid-19 testing, treatments, and potential vaccines free and expanding Medicaid for the duration of the pandemic.
"It has always been a crisis that tens of millions of Americans have no or inadequate health insurance—but in a pandemic, it's potentially catastrophic for public health," the task force wrote.
Dr. Abdul El-Sayed, a former Michigan gubernatorial candidate and Sanders-appointed member of the Healthcare Task Force, said that despite major disagreements, the panel "came to recommendations that will yield one of the most progressive Democratic campaign platforms in history—though we have further yet to go."
We rein in #pharma's greed by: 1) Allowing Medicare to FINALLY negotiate Rx drugs FOR ALL AMERICANS 2) Using Rx d… https://t.co/6k9iUCLMp7— Abdul El-Sayed (@Abdul El-Sayed)1594238411.0
Observers and advocacy groups also applauded the Unity Task Forces for recommending the creation of a postal banking system, endorsing a ban on for-profit charter schools, ending the use of private prisons, and imposing a 100-day moratorium on deportations "while conducting a full-scale study on current practices to develop recommendations for transforming enforcement policies and practices at ICE and CBP."
Marisa Franco, director of immigrant rights group Mijente, said in a statement that "going into these task force negotiations, we knew we were going to have to push Biden past his comfort zone, both to reconcile with past offenses and to carve a new path forward."
"That is exactly what we did, unapologetically," said Franco, a member of the Immigration Task Force. "For years, Mijente, along with the broader immigrant rights movement, has fought to reshape the narrative around immigration towards racial justice and to focus these very demands. We expect Biden and the Democratic Party to implement them in their entirety."
"There is no going back," Franco added. "Not an inch, not a step. We must only move forward from here."
