It would take away breeding ground for human transmittable mutations. With literally billions of animals, mainly in filthy conditions, we just keep rolling the dice every day for a strain that starts a pandemic. We can either try to abolish factory farming, or just hope that the next pandemic won’t be much worse than covid.
This one isn’t human to human transmittable. It jumped to one human, but can’t infect other humans from there, so unless it mutates in a bad way it won’t start a pandemic. That’s very unlikely with one infection, but there will be more if it stays on animal farms.
