The result is increasing outbreaks of super bugs, fed by over use of antibiotics as well as improper disinfection. They originate in the dust clouds produced by industrial pollution, these clouds of dust rise into the higher earth atmosphere where bacterial and fungal microbes collect and continue to mutate. These dust clouds return to earth to spread new mutated microbes into the air we breath.
The super-bugs continue to mutate as they build resistance to antibiotics and disinfectants. I will go into more detail on this problem in a later blog post.
In the study below Cryptococcus is a form of fungi that is mutating as a result of living in the earth atmosphere in dust clouds.
A key moment in aeromicrobiology, or the study of airborne microbes, came in 1933, when Fred Meier of the US Department of Agriculture convinced Charles Lindberg to collect samples during an arctic flight from Maine to Denmark. Upon finding everything from fungal spores to algae and diatoms, Meier wrote, "the potentialities of world-wide distribution of spores of fungi and other organisms caught up and carried abroad by transcontinental winds may be of tremendous consequence."
One of the most surprising new findings about airborne microbes is that far from being passive passengers of the wind, some are truly adapted to life in the mesosphere—70 km above the earth's surface—where they must constantly repair their DNA following bombardment by direct UV radiation. Or take a 2008 study that found that airborne microbes haunting Singapore shopping malls are not a random sample of what's outside, but are specialized for survival in the indoor air environment.
