I’ve always been of the opinion that it’s arrogant and hypocritical for humans to call any other animal vermin!
Even with all our medicines, vaccines and biosecurity measures we still constantly spread disease. We shouldn’t have needed COVID to teach us basic hygiene like hand washing and not coughing all over people/covering your face if you are sick etc. Flu existed before this particular coronavirus (not the first one or that special really apart from coming out of a lab) and that still kills people also. But it’s like some people have only just figured out what germs are and only NOW consider the fact that they could potentially make others sick. Some employers have only just realised that if you are sick maybe you should stay home.
