For John Palmer and Harpy, please stop publishing BS about the virus origin. I know it would be reassuring if it was produced by humans, because it would means that with a better control of humans, we would be on the safe side, that we don't need to change our way of life.
Pandemic viruses are a normal evolution, because mutations happens all the times, but most of the mutations can be controlled directly by our body, some can be controlled by our health care system, and once in a while, like every 100 years, probably even less, there is one mutation that just can't be stopped.
Our globalization makes it worse because we mix our populations constantly, if the plague took years to go to most part of the world, few weeks were enough for the Covid19. Furthermore, using each piece of land available on earth is like searching for forgotten viruses.
Until Covid19, we have been very lucky that other viruses like Ebola didn't go all over the world.
