Yet another reason to move to a plant-based lifestyle. Covid came from some folks in China using exotic animals for some purpose. Now a new variant seems inevitable from animal populations. Is it worth the burgers and coats?
Are they though? Mass farming puts humans into orders of magnitude more contact with animals than wet markets. In the case of covid, a wet market led to the disease. There are plenty of cases — just about the majority of plagues — where a domesticated animal led to disease
In some ways the dangers are different, perhaps more manageable in some cases. For wet markets, it's the unknown from nature. In the case of Domesticated markets, it is more typically an issue either from failures in procedure (i.e. e.coli/listeria/salmonella) or because of over-industrialization (Mad Cow Disease)
And maybe it was aliens, we don't know yet. But it's not really helpful to suggest random theories without a shred of evidence on the off-chance that they might be accurate, because that rabbit hole has no bottom.
