"You may be interested (or possibly horrified) to discover you ingest and
inhale thousands of tiny life forms on a daily basis.
The air and surfaces around you are home to multitudes of bacteria, fungi,
viruses, mites, algae and protozoa. Your skin isn’t much better, with a complex
ecosystem of organisms called commensals which aren’t necessarily good or bad,
but will shift in their composition depending on where you live, the products
you use and the pets you have.
Most of these creatures are generally undetectable due to their microscopic
size and low concentrations. But when they find a niche they can exploit, you
might notice them by their smell, or the appearance of unwanted staining and
colour changes. A lot of this fungal growth is what we call mould.
We’ve all been disappointed in ourselves at one time or another, lifting a
neglected orange out of the fruit bowl to discover the bottom half is covered
in a velvety blue-green growth.
But what do the myriad colours that appear on our stuff tell us about the world
we try not to think about?"
