As the world focuses on the zoonotic COVID-19 outbreak, we are bringing focus back to the Oct. 22, 2019, release of The Berlin Principles, which are an urgent call to governments, academia, and civil society that all sectors need to break down barriers to ensure a united effort to prevent the emergence or resurgence of diseases that threaten humans, wildlife, and livestock.

The Berlin Principles were developed and issued at the "One Planet, One Health, One Future" conference organized by the Wildlife Conservation Society and the German Federal Foreign Office. The conference included the top minds from around the globe addressing how human development and interference on nature are generating threats affecting all life on Earth.

The New York Times: China ban big but traffickers may exploit loopholes, conservationists say

Dr. Christian Walzer, WCS’s chief global veterinarian, said China's new ban “is a big step in the right direction.” The ban goes to the “root cause” of the COVID-19 outbreak, he said which he and most other scientists view as human harvesting of wild animals.

“But there is a huge trade in wildlife that is not related to consumption.”

February 26, 2020

STATEMENT: A critical and positive step but other forms of trade should be added

“WCS welcomes this critical and positive step that reflects the Chinese central government’s commitment for not only solving the COVID-19 outbreak but in preventing future risks through legislative reform and improved enforcement and management.

“There is no such risk-free trade and consumption of any wild mammals and birds whether they are wild-caught or farmed. WCS believes that only by prohibiting the live trade in all wild birds and mammals can the risk of future viral emergences be prevented, and thus other forms of trade should also be included in this ban.

“In addition, this creates a potential loophole for traffickers who may exploit the non-food exemptions to sell or trade live wildlife, creating additional challenges to law enforcement officers.”

STATEMENT: WCS applauds China for revising and strengthening wildlife protection laws

“Preventing future zoonotic outbreaks is not about targeting one species—like pangolins, bats and snakes—but taking strong actions to ban wet markets trading in wildlife and broadly strengthening wildlife laws and regulations," said WCS's Dr. Christian Walzer. "We applaud The National People’s Congress of the People’s Republic of China for declaring on Monday that it is revising wildlife protection laws, in order to strengthen the fight to end indiscriminate hunting and consumption of wild animals."

VIDEO: Wildlife markets are the most important factor in the emergence of COVID-19

January 30, 2020

Key questions answered

What is the Wildlife Conservation Society's main message concerning the COVID-19 coronavirus?

As Dr. Walzer states in the video above, WCS is asking China and others governments to close live animal markets that trade in wild animals—whether these animals come from the wild or whether they are farmed-wildlife. There are three clear steps we are advocating for to prevent the spread of similar zoonotic diseases: close live animal markets that sell wildlife; strengthen efforts to combat trafficking of wild animals within countries and across borders; and work to change dangerous wildlife consumption behaviors, especially in cities.

Won’t closing these markets hurt the poor?

No. Wildlife populations are being depleted as they are poached and hunted. Viral outbreaks lead to mass culling of domestic animals, which increases the cost of basic animal protein, hitting the poor the hardest.

Why do we suspect the COVID-19 coronavirus is a spill-over from animals to humans?

Scientists from the Chinese Centre for Disease Control have confirmed a live animal market teeming with a multitude of wildlife species as the origin of the COVID-19 coronavirus. Dr. Zhong Nanshan, director of the China State Key Laboratory of Respiratory Disease, who became famous for leading the fight against SARS 17 years ago, pinpointed on Chinese state television the likely source of the new coronavirus as wildlife. Environmental samples from the Wuhan market have been linked to wildlife.

Why are these live animal markets that sell animals for food such a problem?

It is hard to design more perfect conditions for new viruses to emerge than market systems such as that in Wuhan: Tightly pack together a variety of species from around the country or the world and transport them long distances directly into large markets. Ensure that these massively stressed and immuno-compromised wild animals are in close proximity to domestic and farmed animals. Then distribute these animals out to major urban populations for consumption.

What action has the Chinese government taken about these markets with this outbreak?

The Chinese government is to be applauded for acting quickly, as three government agencies took the first step, announcing a nationwide ban prohibiting all wild animal trading activities with immediate effect. This includes not only wet markets, but supermarkets restaurants and e-commerce platforms. The announcement also stated that “any violation of the provisions of this announcement shall be investigated and dealt with severely in accordance with the law and regulations”. However, this is not enough, as the ban currently only covers the period until “the epidemic situation is lifted nationwide”. It must be permanent.

Is it a common occurrence for viruses to be transmitted from animals to humans?

The resulting re-assortment and exchange of viral components between species at live animal markets is a major source of new viruses. These can be zoonotic, i.e., transmitted from animals to humans (e.g., Avian Influenza, SARS, MERS), and subsequently successfully mutate so that they can transmit between humans, creating the conditions for a rapid global pandemic.

Are there markets like this outside of China?

Similar markets occur in cities across other Asian countries and if these persist, and human consumption of wildlife goes on, then we will continue to face heightened risks from emerging new viruses, potentially more lethal.

What do the people in China and Chinese media think about closing these markets?

A large and growing number of people in China support closing these markets. On Chinese social media, support for the issue has been among the highest trending topics on Weibo (China’s most popular microblog site) over the last week, with the hashtag “#The Source of the New Coronavirus is Wild Animals” viewed 1.2 billion times. The hashtag "#National Wildlife Trading Is Banned Until the Epidemic is Over” has amassed 400 million views over 24 hours since it was announced, and the view of Chinese netizens is clear: “It should be permanently banned. Do you want to have another epidemic?,” “Reject wild meat, ban forever and punish offenders severely,” “It is for the sake of human life, health, safety, and maintenance of natural harmony that wildlife trading activities should be permanently banned from now on.”

Not only that. State media and academics agree. The China Daily recently headlined, “It’s Time to Permanently Ban Wildlife Trade” and Sina News, “It’s Time to Ban Wild Animal Trading.” While a group of senior Chinese academics, including the former president of Peking University and Dr. Shi Zhengli of Wuhan Institute of Virology, Chinese Academic of Science (who is one of the scientists who identified bats as the original carrier of SARs), have publicly called on China’s National People’s Congress to end the illegal trade and consumption of wild animals by issuing emergency legislation integrating public health and safety concerns into the wildlife protection law.

Consumption of wild meat appears to be to blame for the COVID-19 virus, as it was for SARS in 2003. We must abolish wet markets where these pandemics breed, write WCS's Christian Walzer and Aili Kang write in The Wall Street Journal.

January 26, 2020

STATEMENT: Chinese ban on wildlife markets needs to be permanent

“The Chinese government’s announcement today to temporarily ban the sale of wildlife in markets, restaurants and over e-commerce needs to be permanent," said WCS's Dr. Christian Walzer. "We congratulate the government for taking this important first step."

“The banning of such sales will help end the possibility of future outbreaks of zoonotic diseases, such as the COVID-19 coronavirus. We learned this lesson with the outbreak of another zoonotic disease, SARS, in 2002. The pattern will keep repeating itself until we ban, not only in China, but in other countries, the sale of wildlife, specifically for food and in food markets."

The Guardian: Calls for global ban on wild animal markets

Wild animal markets must be banned worldwide, say experts in and outside China, warning that the sale of sometimes endangered species for human consumption is the cause both of the new coronavirus outbreak and other past epidemics.

The Huanan seafood market in Wuhan, which has been closed down as the source of the infection, had a wild animal section, where live and slaughtered species were on sale. An inventory list at the Da Zhong domestic and wild animals shop inside the market includes live wolf pups, golden cicadas, scorpions, bamboo rats, squirrels, foxes, civets, hedgehogs (probably porcupines), salamanders, turtles and crocodiles. In addition, it offered assorted parts of some animals, such as crocodile tail, belly, tongue and intestines.

January 22, 2020

STATEMENT: Close live animal markets that trade in wildlife

“Governments must recognize the global public health threats of zoonotic diseases," said WCS's Dr. Christian Walzer. "It is time to close live animal markets that trade in wildlife, strengthen efforts to combat trafficking of wild animals, and work to change dangerous wildlife consumption behaviors, especially in cities. It is essential to invest resources not only into discovering new viruses but more importantly in determining the epidemiological drivers of zoonotic spillover, amplification, and spread of infectious diseases."
