400 years ago, the majority of respectable physicians agreed that bad
smells were the cause of disease. We really need to rid ourselves of this
conceit that we know better. We know more, certainly. But better ?

Some diseases are caused by invisible to them agents that can generate
bad smells, so they were at least partly right in that some bad smells
are connected with some diseases.

Malaria, for instance is caused by microbes carried by mosquitoes that
breed in smelly, stangnant water. Get rid of the smelly water, and the
incidence of malaria is reduced locally.

Cholera is caused by organisms that grow in water contaminated by
sewage, which causes a bad smell. Get rid of the smelly water and the
cholera stops.

They were doing the best they could with the knowledge and equipment
they had. Much as we are doing with global warming now. If we reduce
what we think is a major contributory cause, and that doesn't stop it,
then we need another theory. Making less CO2 is a good aim for other
reasons, anyway.
