…and why it is a key pandemic vector:
This expanding industrial footprint has accelerated the flow of pathogens into new territories around the world. In Central Africa, the growth of bushmeat hunting—linked to a dearth of local fish due to Chinese and EU overfishing—has spread monkeypox, a smallpox-like virus, from rodents to humans. In China, the growing prosperity of the middle class has led to an increased demand for the luxury “yewei” cuisine, which revolves around the consumption of rare, exotic wild animals; live animal (or “wet”) markets, where such wild animals are sold, have grown accordingly. These wet markets facilitated the emergence of SARS-CoV-1 in bats, civet cats, and humans in 2002 and, some speculate, the novel coronavirus in 2019. And in southeast Asia, rising incomes have led to the increased consumption of pork and the growth of pig farms. The expansion of swine farming in Malaysia precipitated the transmission of Nipah virus from bats to pigs and then humans in 1998; similarly, in China, the expansion of swine farming has led to the frequent emergence of highly virulent forms of avian influenza viruses and antibiotic-resistant pathogens.
And more on “wet markets,” and why shutting them down is a complicated question:
Among today’s wet markets, you’ll find some that sell no live animals whatsoever, just slaughtered animals and produce; some that carry common live animals like chickens or fish; and some that sell wildlife like bats and snakes.
While US lawmakers and other public figures talk about wanting to ban wet markets writ large, what they seem to really want to ban is the sale of wild animals — or perhaps any live animals — that sometimes occurs there. (Presumably they would have no problem with the wet markets that carry only slaughtered meat and produce; after all, the US is full of such markets.)
Which is why (can’t refrain), the most comprehensive solution would be evolution toward plant-based diets. Just saying.
