This is a shot from the broccoli bin in one of my favorite local grocery's. They have the best produce and for very good prices. There was no actual mold present, as the place is very clean, though aged.
When I began to alter this photo to make it look more dingy I began to think about how it looked like a place where mold could grow and then, about mold in general. I began to think about the fact that mold, as disgusting and repulsive as it is, is just another way in which nature reclaims. It's actually a pretty impressive way
From Wikipedia: Although molds grow on dead organic matter everywhere in nature, their presence is only visible to the unaided eye when mold colonies grow. A mold colony does not comprise discrete organisms, but an interconnected network of hyphae called a mycelium.
Some mold can begin growing at temperatures as low as 2°C. When conditions do not enable growth, molds can remain alive in a dormant state, within a large range of temperatures before they die.
