You obviously do not understand how pandemics and viruses work.
You cannot stop an earthquake but you can manage your response to it.
Same thing with Covid19, many countries were ready for it some more or less than others.
Viruses mutate very fast and are known to hop from one animal to another like mosquitos, bats, pigs and birds etc. These type of virus are some of the most dangerous.
The main policy now is social distancing to flatten the curve until we have a vaccine that can help the most vunerable people such as elderly and immunocomprimsed people.
Worldwide there are over 1,600,000 different viruses in animals and so far we only have a database of 3000 of them. It was only a matter of time that one mutated and came into humans. Its happening now and it will happen again.
Its not just about meat markets, this can happen in farms and in the wild, as more and more land is reclaimed by deforestation the higher the chance that humans can come in contact with newer and deadlier viruses.
These pandemics should be taken more seriously because they can kill more people than world wars.
There are many books and documentaries on pandemics on youtube and netflix that were made before 2019 and its striking how accurate the science was.
