It might be fair comment that what's going on would be a lot less likely in a world of vegans where direct contact between humans and animals was extremely rare.
But the 'wet market' thing is just a vaguely racist red herring.
Any virus that infects domesticated animals will inevitably infect humans, if it is able. This one may have done so at a Chinese market. No-one actually knows. But if it didn't, then it would instead have happened at a farm, slaughterhouse, livestock market or whatever
Well, no, no and no.
In a word of vegans direct contact between humans and animals would not be extremely rare. On the contrary, it could exist more contact, but in a context or respect, and there would not be exploitation. Therefore we would all be healthier.
The "wet market thing" is not a racist term, it reflects the harsh reality of some countries. Sadly, in my third world country people eat a lot of meat. But we don't have "wet markets" because even in our extremely carnivorous culture those atrocities are not morally tolerated.
Not any virus that infects domesticated animals will infect humans, because the fact that some animals have been domesticated for thousands of years has allowed people's immunization. The huge problem arises when humans exploit wild animals, or they exploit domesticated animals differently than in the way in which the link between those animals and humans was originally established (eating dogs and cats, for example).
