The pandemic wasn't a huge surprise, it was just the biggest of several over the last few decades. Still not as bad as the 1918 pandemic.
There are plenty of factors that make this more of an issue - increased population pushing into new areas, poor people using wild animals for food, climate change encouraging spread of mosquitoes, more travel allowing quicker spread...
The problem with regulating these markets is that this would need to happen world wide. Next time it could be from Africa.
And while China delayed a little on reporting this, I could easily see an African nation not even detecting problems till its spread widely.
Sure we should try to phase these out, but they survive as either cheap meat or cultural reasons for a particular meat. Hard to regulate. Im sure China could do it, but plenty of other places would struggle.
And WHO doesn't really have any power, all it can do is make recommendations, its then up to countries to listen. While WHO recommendations changed, that is because our understanding of the infection changed. I think WHO did a reasonable job.
Research is one area we can control, because that has big money involved and would fall under plenty of rules and regulations.
Could be something that we get countries to sign up to an agreement on research safety - maybe get independent inspections for certain research, a bit like nuclear inspections. While this one wasn't a lab leak, it doesn't mean that we should assume it could never be a lab leak.
I think this sort of research can be important, as long as it for general betterment, not as weapons!
Now Im sure there are people discussing these sorts of issues. But they are not sexy click-bait, so we probably dont see it in general media.
