Stumbled across this article today.
Sounds kinda interesting.
It offers a good food for thought.
Even though you won't think of food when reading this.

[Health News] Washington, Dandruff which causes much irritation by making the scalp flaky and itchy may also account for a much larger proportion of air pollution, than earlier believed, according to a new study.
The study suggests that particles of skin, pollen, fur fibers, and other cell fragments may account for up to 25 percent of the particles in the atmosphere.
Particles suspended in the atmosphere, known as aerosols, play an important role in climate change. But researchers say they need a better understanding of what those aerosols are made of so they can build more accurate climate change models.
Aerosols produced by burning fuel and other human activities have been the primary focus of attention for their contributions to air pollution and climate change. But aerosols from natural sources such as plants and animals, known as "bioaerosols," have been considered a minor source of air pollution until now.
[Health News] In the study, which appears in the current issue of the journal Science, researchers analyzed aerosols collected from different environments and in different seasons.
They identified a broad array of bioaerosols in the samples, including fur fibers, dandruff, and skin as well as fragments of plants, pollen, spores, bacteria, algae, fungi, viruses, and protein crystals.
In some cases these natural air pollutants accounted for up to 25% of the total particles in the atmosphere.
In spring, the results showed that pollen is more abundant, and in winter, dead skin and other cells are the predominant sources of bioaerosols. (ANI)
