The comment I was replying to saying that almost all diseases and cancers are caused by it isn’t the same thing though. Disease and cancer has been around for a long long time before the use of fossil fuels.
Admittedly I did smush the two together so I'd have to rethink whether "all deaths [that are] linked to pollution" is as reasonable as "all deaths [that are] linked to air pollution" -- I suspect it probably still would be because of the sheer scale of fossil fuels, but regardless, desert sand still beats fossil fuels anyway
