As another comment mentioned, the one we just lived through where I had to be inside for 2 years. It came from a live meat market.
I wouldn't be surprised if we get a sufficiently human-transmissible avian flu pandemic within the decade, given how many non-avians the current strain has been killing in addition to birds.
Which pandemic was caused by people eating meat?
Much of what you said is true, but some of it is a stretch, and taken altogether it seems like an exaggeration.
