A pathway to the understanding of mosses? (III)
Mosses do have lots of enemies, in particular in the commercial field. A global
player in chemistry products doesn't hesitate to summarize their properties,
rather stone-hearted, as follows:
Mosses: Soiling, material degradation and dangerous, slippery surfaces!
Well, there are motives for such statements. The chemical production is providing
many, many products which are intended to be sold for an enduring fight against those
evil mosses. And, of course, the supplier has a tendency to make profit in this field.
Constant demand due to a constant fight - a perfect market situation. So, the statement above
is understandable, somehow. But in order to reach a more balanced assessment we must keep in mind
that the moss characterization by the suppliers of chemical products is based solely
on sales interest. As a consequence the moss positives are being skipped.
We would like to emphasize that the beautiful, ideally (half-)spherical geometry
of the moss cushions which is a par excellence support of Darwin's thoughts -
a shield and perfect proof of the never-ending fight for existence on earth.
No, not only the brute fight against those human individuals who are cleaning
their pavement borderlines on a daily basis.
Alos the necessity to withstand the extremes of rain and drought.
Stone and pavement mosses receive their water supply only from rainfall.
So they must be able to defend themselves against this water but at the same time
to be able to store it as well.
