It isn't practical to make every space as sterile as a clean room. Outside air also carries pathogens.
Besides, humans and our ancestors have spent millions of years exposed to all sorts of things. It is why we have an immune system.
- isp 3y agoThis is a good example of exactly the kind of argument that would have been made against clean water 175 years ago, and which (I predict) will be unthinkable to make decades from now against clean air. The rise of respiratory pathogens corresponds with dense cities, which are only a few thousand years old. This is the blink of an eye in evolutionary terms. This is different for humans than for bats, which co-evolved for millions of years with such pathogens.
