How can we have mold
in the desert ?
Even in the desert molds form naturally in the environment or are blown in by the winds. Molds can travel thousands of miles on the natural atmospheric currents. Mold is nature’s way of cleaning itself of unwanted cellulosic materials; wood, paper, plant materials, etc.
In the desert environment molds are common but usually limited by lack of moisture due to the dry environment. Mold needs moisture, a food source, a minimal air movement and a dark, relatively cool place to thrive. Take one of these factors out of mold’s environment and development is not likely.
Doesn’t sound as if there would be much mold here, however – We don’t LIVE in the desert. We live and work in an artificial environment of our own making.
We put up buildings and create a more hospitable environment for our selves inside them – with Air Conditioning and heat, wood flooring, insulation, moisture barriers and drywall. The environment we live in and the construction methods and materials we use are what allows mold to become a factor in our homes, businesses and offices.
True in any geographical area.
• Moisture – Any water leak can be enough to provide the moisture needed to produce mold. The longer things are wet – the more the probability of mold growth. This is why time is of the essence in properly drying a structure after a water intrusion.
• Food source – Drywall is an excellent food source – The paper covering on drywall is essentially a partially digested wood pulp. Mold loves this and is the reason why mold first begins to form (or show) on drywall products. Any wood product can supply the food source mold needs to grow. The more processed the product – the sooner mold will find a home in it. Mold will form faster on the paper covering of drywall products than the solid wood of framing.
• Minimal air movement and dark conditions – The interior spaces of most every wall, flooring and ceiling structure provide these conditions quite readily, and mold loves it!
Mold is in
because it loves
the comfortable living conditions we’ve created for ourselves and the materials we’ve used to do it.
If we were to really live in the desert
(with no A/C, heat,
ceilings or walls)
mold would never
be a problem here.
